Question 1

Which is not a feature of Hyperkinetic child?

Accepted Answer

Answer reason: Hyperkinetic disorder (commonly aligned with ADHD) is characterized by inattention, hyperactivity, and impulsivity, so a low attention span is typical. Intelligence is usually normal, but learning difficulties or lower test performance may be seen secondarily, so “low IQ” can be an associated finding in some contexts rather than a defining neurologic sign. Stimulants (e.g., amphetamine/methylphenidate) are established first-line pharmacotherapy. “Right to left dissociation” is not a recognized clinical feature of hyperkinetic disorder/ADHD and instead suggests other neurologic or developmental phenomena.
Category reason: This item tests recognition of core clinical features and treatment of a neurodevelopmental/behavioral condition rather than a nursing intervention, prioritization, or safety action, so it fits NursingScience under Neurology.

Question 2

Which condition is characterized by "demyelination" of neurons?

Accepted Answer

Answer reason: It is an immune-mediated disorder of the central nervous system in which inflammatory attacks damage myelin and oligodendrocytes, producing plaques of demyelination. This disrupts saltatory conduction and causes neurologic deficits that are often disseminated in time and space (e.g., optic neuritis, sensory loss, weakness). By contrast, Parkinson’s primarily involves dopaminergic neuron degeneration, stroke is focal ischemic/hemorrhagic injury, and epilepsy reflects abnormal electrical activity rather than primary myelin loss.
Category reason: This is a foundational question about the defining neuropathology (demyelination) of a neurologic disease rather than a nursing intervention or care priority, so it fits NursingScience under Neurology.

Question 3

A positive Babinski reflex in an adult indicates...

Accepted Answer

Answer reason: In adults, an extensor plantar response reflects loss of corticospinal (pyramidal) tract inhibition of the spinal reflex arc. This makes it a classic sign of an upper motor neuron process such as stroke, multiple sclerosis, or spinal cord tract disease above the S1 level. It is not a normal adult finding, and lower motor neuron lesions more typically reduce reflexes rather than produce this pathologic response. While spinal cord injury can cause it, the reflex specifically localizes to upper motor neuron/corticospinal tract dysfunction rather than being limited to traumatic injury.
Category reason: This question tests interpretation of a neurologic reflex sign (Babinski) and what lesion type it indicates, which is foundational neuroanatomy/neurologic pathophysiology rather than a nursing intervention or prioritization decision.

Question 4

Which part of the brain is responsible for coordination and balance?

Accepted Answer

Answer reason: It integrates proprioceptive, vestibular, and visual input to fine-tune voluntary movement, maintaining posture, gait, and equilibrium. Lesions classically cause ataxia, dysmetria, intention tremor, and impaired balance/coordination. In contrast, the cerebrum mediates higher cognition and voluntary motor planning, the brainstem controls vital autonomic functions and cranial nerve pathways, and the hypothalamus regulates endocrine and autonomic homeostasis.
Category reason: This is a foundational neuroanatomy question testing which brain structure controls coordination and balance, which falls under Neurology.

Question 5

Impaired consciousness, visual hallucination, hyperactivity and fragmentary delusions are?

Accepted Answer

Answer reason: This presentation is classic for an acute confusional state with fluctuating level of consciousness and prominent perceptual disturbances. Visual hallucinations, psychomotor agitation (hyperactivity), and transient, poorly systematized delusions are typical features, often with impaired attention. Dementia usually has a more chronic course with relatively preserved consciousness early, and schizophrenia/paranoid psychosis do not characteristically cause impaired consciousness.
Category reason: This question tests recognition of a neurocognitive syndrome based on symptoms (consciousness level, hallucinations, psychomotor activity), which is a foundational clinical neuroscience/psychiatry knowledge task rather than a nursing intervention/prioritization scenario.

Question 6

Dementia is seen in all except?

Accepted Answer

Answer reason: Dementia is a chronic, progressive decline in cognitive function seen with neurodegenerative diseases and certain brain injuries. Head injury (especially repetitive or severe traumatic brain injury) and Huntington’s chorea are well-known causes of dementia. Schizophrenia can produce chronic cognitive impairment and may be described historically as “dementia praecox,” but it is not a true progressive dementia syndrome; however, cannabis does not characteristically cause a dementia syndrome, though it can cause acute intoxication and transient cognitive deficits.
Category reason: This is testing causes/differentials of dementia (neurologic disease and brain injury vs substance effects), which is foundational biomedical knowledge rather than a nursing intervention scenario, fitting Neurology.

Question 7

Which cranial nerve controls movement of the tongue?

Accepted Answer

Answer reason: It provides motor innervation to the intrinsic and most extrinsic muscles of the tongue, enabling tongue protrusion and movement needed for speech and swallowing. Lesions cause tongue weakness and deviation toward the affected side due to unopposed action of the contralateral muscles. In contrast, CN V primarily controls muscles of mastication, CN VII controls facial expression, and CN IX is mainly sensory/taste to the posterior third of the tongue with limited motor to stylopharyngeus.
Category reason: This question tests foundational knowledge of cranial nerve function and motor innervation of the tongue, which is a core topic in neuroanatomy/neurology rather than nursing interventions or prioritization.

Question 8

Synapses are the gaps between?

Accepted Answer

Answer reason: A synapse is the specialized junction where one nerve cell communicates with another cell, most commonly another nerve cell. The synaptic cleft is the small gap that separates the presynaptic neuron terminal from the postsynaptic membrane, allowing neurotransmitters to diffuse and transmit signals. Nephrons are functional units of the kidney, the cell membrane is not a structure “between” two cells in this context, and protons/neutrons are subatomic particles unrelated to neural signaling.
Category reason: This question tests basic neurobiology terminology about how nerve cells communicate, which is a foundational concept within the Neurology subject area.

Question 9

Child present with fits of right side of perioral area and tongue which of the following seizure can be characterized?

Accepted Answer

Answer reason: Focal motor seizures involving the face, perioral region, and tongue are characteristic of benign rolandic epilepsy (benign partial seizures), which originates from the centrotemporal region. Absence seizures typically cause brief staring spells without focal motor findings. Generalized tonic-clonic (grand mal) seizures are bilateral with loss of consciousness and generalized convulsions rather than isolated facial/tongue involvement. Complex (focal impaired-awareness) seizures usually include impaired awareness and automatisms, not isolated unilateral perioral/tongue motor jerks.
Category reason: This question tests recognition of a seizure type based on focal neurologic manifestations, which is foundational Neurology knowledge rather than a nursing intervention or prioritization task.

Question 10

Which lobe processes sensory information related to touch and temperature?

Accepted Answer

Answer reason: The primary somatosensory cortex (postcentral gyrus) is located in the parietal lobe and is responsible for processing tactile sensation, including touch, pressure, pain, and temperature. Sensory inputs from the body are relayed via the thalamus to this region, where they are localized and interpreted. Lesions here commonly cause contralateral sensory loss or impaired discrimination (e.g., astereognosis).
Category reason: This question tests knowledge of brain functional neuroanatomy—specifically cortical localization of somatosensory processing—so it fits best under Neurology.

Question 11

The place where the nerve impulse passes from one neurone to another is known as-?

Accepted Answer

Answer reason: This is the junctional site where one neuron communicates with another (or with an effector cell) via neurotransmitter release across the synaptic cleft. It is the key structure enabling transmission between separate neurons, unlike continuous conduction along a single axon. Nodes of Ranvier are gaps in myelin that speed conduction within one neuron, while myelin sheath insulates the axon and neuroglia are supporting cells.
Category reason: This item tests foundational neuroanatomy/neurophysiology terminology about where neuronal signaling is transmitted between cells, which best fits Neurology rather than nursing care decision-making.

Question 12

What is the function of the myelin sheath?

Accepted Answer

Answer reason: Myelin electrically insulates the axonal membrane, reducing current leakage and decreasing membrane capacitance. This enables saltatory conduction, where action potentials “jump” between nodes of Ranvier, greatly increasing conduction velocity and efficiency. Demyelination disrupts this process, leading to slowed or blocked nerve impulse transmission and neurologic deficits.
Category reason: This question tests the role of myelin in nerve impulse conduction, a core concept in the structure and function of the nervous system (neurology/physiology) rather than a nursing intervention or clinical decision.

Question 13

Which lobe of the cerebrum is primarily responsible for processing visual information?

Accepted Answer

Answer reason: The primary visual cortex (V1) is located in the occipital lobe and receives input from the lateral geniculate nucleus via the optic radiations. This region performs initial processing of visual features such as edges, orientation, and motion, then distributes information to association areas for higher-level interpretation. Lesions here commonly cause contralateral visual field deficits (e.g., homonymous hemianopia), supporting its central role in vision.
Category reason: This question tests localization of brain function (which cerebral lobe processes vision), which is foundational neuroanatomy/physiology within Neurology rather than a nursing intervention scenario.

Question 14

Which nerve controls eye movement?

Accepted Answer

Answer reason: Eye movements are controlled by extraocular muscles innervated primarily by cranial nerves III, IV, and VI. Among the listed options, cranial nerve III provides motor control to most extraocular muscles (medial, superior, and inferior rectus; inferior oblique) and also elevates the eyelid. The optic nerve is sensory for vision, the facial nerve controls facial expression, and the trigeminal nerve is mainly facial sensation and mastication.
Category reason: This question tests cranial nerve function (which nerve supplies motor control for eye movement), a foundational neuroanatomy/neurophysiology topic rather than a nursing management or intervention decision.

Question 15

Muscles of the eye are supplied by all of the following cranial nerves except?

Accepted Answer

Answer reason: Extraocular muscles are innervated by cranial nerves III (oculomotor), IV (trochlear), and VI (abducens). Cranial nerve XII (hypoglossal) supplies motor innervation to tongue muscles, not the eye. Therefore, it is the exception among the listed nerves for eye muscle supply.
Category reason: This question tests which cranial nerves innervate extraocular muscles, which is foundational neuroanatomy/neurophysiology knowledge rather than a nursing intervention or clinical decision.

Question 16

What are the two main parts of the human body's central nervous system?

Accepted Answer

Answer reason: The central nervous system (CNS) is anatomically composed of the brain and spinal cord, which integrate and process sensory input and generate motor output. Peripheral nerves belong to the peripheral nervous system (PNS), which connects the CNS to the rest of the body. The heart is part of the cardiovascular system and is not a nervous system structure.
Category reason: This question tests foundational knowledge of nervous system anatomy—specifically the definition and components of the CNS—so it fits Neurology within NursingScience.

Question 17

The spinal cord is linked to the peripheral nervous system through?

Accepted Answer

Answer reason: C) spinal nerves Spinal nerves emerge from the spinal cord via dorsal (sensory) and ventral (motor) roots and carry mixed afferent and efferent fibers to and from the body. They are the direct anatomical connections between the central nervous system (spinal cord) and the peripheral nervous system. Interneurons are confined within the CNS, sensory neurons are only one functional component of peripheral pathways, and the thalamus is a brain relay center not a conduit to the PNS.
Category reason: This is a foundational neuroanatomy question about how the spinal cord connects structurally to the peripheral nervous system, which fits Neurology within NursingScience rather than patient-care decision-making.

Question 18

Gray matters consist of?

Accepted Answer

Answer reason: Gray matter is primarily composed of neuronal cell bodies, dendrites, unmyelinated axons, and supporting glial cells, making it the main site of synaptic integration and processing. In contrast, white matter is rich in myelinated axons, which appear lighter due to lipid-heavy myelin. Therefore options emphasizing axons or myelin alone better describe white matter rather than gray matter. “Only synapses” is too narrow because gray matter includes multiple neural elements beyond synaptic junctions.
Category reason: This question tests foundational neuroanatomy—what structures comprise gray matter versus white matter—so it belongs to Neurology within NursingScience rather than a nursing care/judgment domain.

Question 19

What part of a neuron is destroyed in multiple sclerosis?

Accepted Answer

Answer reason: Multiple sclerosis is a demyelinating disease of the central nervous system in which immune-mediated inflammation damages myelin produced by oligodendrocytes. Loss of myelin disrupts saltatory conduction and slows or blocks nerve impulse transmission, leading to neurologic deficits. The axon itself may be secondarily injured later, but the primary structure targeted early is the insulating myelin layer.
Category reason: This question tests foundational knowledge of a neurologic disease mechanism (demyelination in multiple sclerosis), which is primarily Neurology rather than a nursing intervention scenario.

Question 20

The cranial nerve most sensitive to radiation is?

Accepted Answer

Answer reason: The olfactory nerve is particularly vulnerable to ionizing radiation because olfactory receptor neurons and their supporting epithelium have relatively high cellular turnover and regenerative activity, making them more radiosensitive than many other cranial nerve fibers. Clinically, radiation to the anterior skull base/nasal cavity can lead to early smell impairment (hyposmia/anosmia). In contrast, several other cranial nerves are more resistant due to more robust myelination and less regenerative epithelial interface.
Category reason: This tests foundational knowledge of cranial nerves and their relative susceptibility to radiation injury, which is primarily a neuroanatomy/neuroscience concept rather than a nursing care decision.

Question 21

Information is carried from the central nervous system to a muscle or gland by?

Accepted Answer

Answer reason: B) motor neurons Efferent (motor) neurons transmit signals from the CNS to effectors such as skeletal muscle fibers and glands to produce a response. Sensory neurons are afferent and carry information from peripheral receptors toward the CNS. Hormones are chemical messengers carried in blood rather than neural pathways, and sensory receptors detect stimuli but do not carry impulses from the CNS to effectors.
Category reason: This item tests foundational neurophysiology of afferent vs efferent signaling between the CNS and peripheral effectors, which fits Neurology rather than a nursing care decision.

Question 22

The peripheral nervous system?

Accepted Answer

Answer reason: The peripheral nervous system (cranial nerves, spinal nerves, and ganglia) connects the brain and spinal cord with the rest of the body. It carries sensory (afferent) input to the central nervous system and motor (efferent) output to muscles and glands. The cerebellum and spinal cord are parts of the central nervous system, and the peripheral nervous system includes both sensory and motor components, not motor only.
Category reason: This is a foundational definition/classification question about nervous system organization and function, which belongs to Neurology rather than clinical nursing decision-making.

Question 23

"Antennae" that extend from a neuron and receive information from other cells are called?

Accepted Answer

Answer reason: Dendrites are branched neuronal processes specialized to receive signals from other neurons at synapses and convey graded potentials toward the soma. Axons primarily transmit action potentials away from the cell body to other neurons or effector cells. The cell body (soma) contains the nucleus and integrates incoming signals rather than serving as the main receiving “antennae.” Synapses are junctions between cells where neurotransmission occurs, not the receiving extensions themselves.
Category reason: This is a foundational neuroanatomy/neuronal function question about the parts of a neuron and how they receive and transmit information, which belongs to Neurology rather than clinical nursing decision-making.

Question 24

A 62 yr. old person with sever major depression has to undergo electroconvulsive therapy what would be the side effect in this patient?

Accepted Answer

Answer reason: ECT commonly causes transient cognitive adverse effects, especially short-term memory impairment and anterograde/retrograde amnesia around the time of treatment. These effects are usually temporary and improve over days to weeks after completing the course. Serious complications like cardiac arrest or brain hemorrhage are rare with modern anesthesia and monitoring, and permanent memory loss is not the typical expected side effect compared with transient impairment.
Category reason: This item tests knowledge of a standard treatment (electroconvulsive therapy) and its expected adverse effect profile, which is foundational neuropsychiatric/neurologic science rather than a nursing judgment or prioritization scenario.

Question 25

Lady having job on X high floor always use stairs not lift she has no hoarsment in lift but afraid to use lift Dx

Accepted Answer

Answer reason: C. specific The fear is focused on a particular situation (using an elevator), leading to avoidance despite no actual threat, which is characteristic of a specific phobia (situational type). Agoraphobia typically involves fear of situations where escape may be difficult (e.g., crowds, open spaces, public transportation) and usually spans multiple settings rather than a single trigger. Social anxiety disorder centers on fear of scrutiny/embarrassment in social or performance situations, which is not described here. The behavior of consistently choosing stairs due to elevator fear best fits a specific phobia.
Category reason: This question asks for the most likely psychiatric diagnosis (type of phobia), which is foundational knowledge about mental/neurologic disorders rather than a nursing intervention or prioritization decision.

Question 26

The myelin sheath?

Accepted Answer

Answer reason: A) insulates axons Myelin is a lipid-rich covering produced by oligodendrocytes in the CNS and Schwann cells in the PNS that electrically insulates nerve fibers. This insulation increases membrane resistance and decreases capacitance, allowing saltatory conduction between nodes of Ranvier and significantly speeding action potential propagation. It does not insulate synapses, directly nourish neurons, or serve as the structure that transmits signals between neurons (that role is primarily via synapses and neurotransmitters).
Category reason: This question tests the structure and function of myelin in the nervous system, which is foundational neuroanatomy/physiology content rather than a nursing intervention or clinical judgment scenario.

Question 27

Which system transmits that you have a pebble in your shoe?

Accepted Answer

Answer reason: C) peripheral nervous system Sensory receptors in the skin of the foot detect pressure/pain from the pebble and generate nerve impulses. These impulses travel along peripheral sensory (afferent) nerves to the spinal cord and brain for perception. The central nervous system processes the information, but the transmission from the foot to the CNS occurs via the peripheral nervous system.
Category reason: This question tests how sensory information from the body is carried to the brain, which is a foundational concept of the nervous system and best fits Neurology.

Question 28

The structure that carries electrical messages away from a neuron's cell body is called a?

Accepted Answer

Answer reason: A) axon Axons conduct action potentials away from the neuron's soma toward other neurons, muscles, or glands. Dendrites primarily receive incoming signals and carry them toward the cell body. A synapse is the junction where signaling occurs between cells, and vesicles store neurotransmitters within the presynaptic terminal rather than serving as the conducting process.
Category reason: This question tests foundational neuroanatomy/function of neuronal parts (axon vs dendrite vs synapse), which is biomedical science content under Neurology rather than a nursing intervention scenario.

Question 29

If a patient has a frontal lobe stroke, which of the following would MOST likely be affected?

Accepted Answer

Answer reason: The frontal lobe mediates executive functions (attention, concentration, planning/judgment), personality, and emotional regulation, so infarction here commonly causes impaired attention, disinhibition, mood/personality changes, and poor decision-making. By contrast, hearing and language comprehension are more strongly associated with temporal lobe function (e.g., Wernicke area in the dominant hemisphere). Sensation and spatial perception localize primarily to the parietal lobe, while vision localizes to the occipital lobe.
Category reason: This question tests localization of brain function (which neurologic deficits correspond to specific cerebral lobes), which is foundational neuroanatomy/neurology knowledge rather than a nursing intervention or priority-setting task.

Question 30

Temporary weakness of the muscles on one side of the face is ........?

Accepted Answer

Answer reason: a) Bell's Palsy This presentation describes an acute, typically unilateral lower motor neuron facial nerve (CN VII) palsy that causes weakness of facial expression muscles on one side. It is often idiopathic and may be associated with viral reactivation and inflammation of the facial nerve, leading to a sudden onset that can improve over weeks to months. Polymyositis is an inflammatory myopathy that usually causes symmetric proximal muscle weakness rather than isolated unilateral facial weakness.
Category reason: This is primarily testing recognition of a neurologic condition (facial nerve palsy) based on a clinical description, which fits Neurology rather than nursing care prioritization or interventions.

Question 31

The feature of Alzheimer’s disease is?

Accepted Answer

Answer reason: Alzheimer’s disease characteristically presents with impairment in short-term memory first, due to early involvement of medial temporal lobe structures (including the hippocampus). Remote (past) memories are relatively preserved early and become affected later as the disease progresses. Therefore, predominant recent memory impairment is the most specific early feature among the options. “Global memory loss” and combined “recent and past” memory loss are more consistent with later-stage dementia rather than the typical initial presentation.
Category reason: This question tests core clinical features of a neurodegenerative disorder (Alzheimer’s disease) and memory-domain involvement, which is foundational Neurology knowledge rather than a nursing intervention/priority scenario.

Question 32

Outward arm/leg extension posture is?

Accepted Answer

Answer reason: This posture is characterized by extension and outward rotation (external rotation) of the upper and lower extremities, reflecting dysfunction at or below the level of the red nucleus in the brainstem. It is typically a sign of severe CNS injury with loss of cortical inhibition and unopposed vestibulospinal and pontine reticulospinal activity, leading to extensor rigidity. Decorticate posturing instead shows flexion of the arms with extension of the legs, while Babinski is a plantar reflex finding and opisthotonus is generalized back/neck hyperextension rather than the classic limb posturing pattern asked here.
Category reason: This question tests recognition of abnormal posturing patterns as neurologic signs related to brainstem/corticospinal tract injury, which is foundational Neurology knowledge rather than a nursing intervention or prioritization scenario.

Question 33

What causes parkinsonism disease?

Accepted Answer

Answer reason: Parkinsonism classically results from degeneration of dopaminergic neurons in the substantia nigra, leading to reduced dopamine in the basal ganglia. This dopamine deficiency disrupts motor circuit balance and produces bradykinesia, rigidity, resting tremor, and postural instability. Diabetes and depression are not primary etiologies, and while stroke can cause vascular parkinsonism, it is not the typical cause compared with dopamine loss.
Category reason: This question tests the underlying neurochemical/pathophysiologic basis of parkinsonism (dopamine deficiency in basal ganglia pathways), which is foundational Neurology knowledge rather than a nursing intervention or safety/prioritization task.

Question 34

Which factor predicts phobia persistence into adulthood?

Accepted Answer

Answer reason: Avoidance behavior is a central maintenance factor in specific phobia because it prevents corrective learning (extinction) and reinforces fear via negative reinforcement. Greater avoidance typically reflects higher symptom severity and functional impairment, which correlates with a more chronic course and persistence into later life. By contrast, parental reassurance is not a robust predictor of persistence, and lack of physical symptoms does not indicate lower fear or better prognosis. Early onset is common in specific phobias but, by itself, is less predictive than the degree of avoidance and impairment.
Category reason: The item tests prognostic/maintenance factors in a psychiatric disorder (specific phobia) rather than a nursing intervention or prioritization decision, making it primarily foundational mental health science.

Question 35

Which of the following cell is found in the brain?

Accepted Answer

Answer reason: The brain is composed primarily of neurons and supporting glial cells; neurons are the excitable cells responsible for receiving, integrating, and transmitting electrical and chemical signals. “Nephrons” are the functional units of the kidney, not the brain. “Epithelial cell” is a broad tissue type lining surfaces and forming glands, not the defining functional cell type of brain tissue. “Helatocytes” appears to be a misspelling of hepatocytes, which are liver cells.
Category reason: This is a foundational question about the primary cell type in brain tissue, which is core nervous system biology rather than nursing interventions or patient-care decision-making.

Question 36

Which Part of the Neuron receives Signals from other neurons?

Accepted Answer

Answer reason: Dendrites are the primary receptive structures of a neuron, containing receptors that bind neurotransmitters released from presynaptic neurons. These inputs generate graded potentials that are integrated at the soma/axon hillock to determine whether an action potential will fire. In contrast, the axon primarily conducts signals away from the cell body, the nucleus regulates cellular function and gene expression, and the synapse refers to the junctional site where signaling occurs rather than a specific neuron part specialized for receiving most inputs.
Category reason: This question tests foundational structure-function knowledge of neurons (which part receives incoming signals), which is a core concept in neuroscience rather than nursing intervention or clinical judgment.

Question 37

The monocytes that migrate from the blood into CNS, are known as-?

Accepted Answer

Answer reason: Monocyte-lineage cells that enter the CNS differentiate into resident macrophage-like immune cells called microglia. These cells provide immune surveillance, phagocytose debris, and orchestrate inflammatory responses within brain and spinal cord tissue. Schwann cells are peripheral nervous system glia, and neurons are not derived from monocytes.
Category reason: This is a foundational question about CNS immune/glial cell identity and origin, which falls under Neurology rather than nursing care decision-making.

Question 38

"Circle of Willis" ensures constant blood supply to the...

Accepted Answer

Answer reason: The Circle of Willis is an arterial anastomotic ring at the base of the brain that provides collateral circulation between the carotid and vertebrobasilar systems. This redundancy helps maintain cerebral perfusion if one contributing vessel becomes narrowed or occluded. It therefore supports more constant blood flow to brain tissue, reducing ischemic risk in certain vascular compromise scenarios.
Category reason: This tests knowledge of a specific neurovascular anatomical structure and its function in maintaining cerebral perfusion, which is foundational neuroscience/anatomy rather than a nursing intervention decision.

Question 39

Which is the fastest nerve in the human body?

Accepted Answer

Answer reason: Nerve conduction velocity is highest in large-diameter, heavily myelinated fibers, particularly alpha motor neurons. The sciatic nerve contains many of these thick, myelinated fibers supplying the lower limb, allowing very rapid impulse transmission. By contrast, the vagus nerve is largely autonomic with many smaller fibers, and “optic nerve” is a CNS tract with different functional framing in many nursing MCQs. Therefore, among the listed peripheral nerves, the sciatic nerve is the best answer.
Category reason: This asks about relative nerve conduction speed and properties of nerve fibers, which is foundational neurophysiology/neurology rather than a nursing intervention or safety decision.

Question 40

The basal ganglia are primarily concerned with ________.?

Accepted Answer

Answer reason: They modulate motor activity by helping initiate intended movements and suppress unwanted movements, influencing muscle tone and posture. Dysfunction of these circuits causes characteristic movement disorders such as bradykinesia/rigidity (e.g., Parkinson disease) or chorea (e.g., Huntington disease). Language comprehension, primary visual processing, and general sensory perception are mainly mediated by cortical regions and thalamocortical pathways rather than the basal ganglia as the primary function.
Category reason: This is testing the primary function of a CNS structure (basal ganglia) and its role in motor control, which is core Neurology content rather than a nursing care decision scenario.

Question 41

What is the most likely diagnosis?

Accepted Answer

Answer reason: B. Idiopathic Intracranial Hypertension Normal brain MRI with elevated CSF opening pressure in a patient with headache and blurred vision is most consistent with increased intracranial pressure without a mass lesion, which is characteristic of idiopathic intracranial hypertension. A brain tumor would more likely show an abnormal MRI, and meningitis typically presents with infectious/systemic signs and CSF inflammatory changes rather than an isolated pressure elevation. Optic neuritis primarily causes painful vision loss and is not defined by elevated CSF opening pressure with normal neuroimaging.
Category reason: This item tests recognition of a neurologic condition based on classic diagnostic findings (normal MRI with high CSF opening pressure) and symptoms, which is foundational disease identification rather than a nursing intervention decision.

Question 42

The Peripheral Nervous System Is Composed Of The?

Accepted Answer

Answer reason: The peripheral nervous system consists of nerves outside the brain and spinal cord, including afferent (sensory) pathways that carry information to the CNS and efferent (motor) pathways that carry commands from the CNS to muscles and glands. The brain and spinal cord themselves belong to the central nervous system, not the peripheral nervous system. Therefore choices that include the brain or spinal cord describe the CNS rather than the PNS.
Category reason: This is a foundational anatomy/organization question about how the nervous system is divided into central vs peripheral components, which fits Neurology within NursingScience rather than nursing interventions or clinical judgment.

Question 43

Longest cranial nerve of the body?

Accepted Answer

Answer reason: It is cranial nerve X and has the widest distribution, traveling from the brainstem through the neck into the thorax and abdomen. It provides major parasympathetic innervation to the heart, lungs, and much of the gastrointestinal tract, making its overall course the longest among cranial nerves. The other listed nerves have more limited anatomical reach and do not extend as far into the body cavities.
Category reason: This asks for identification of a specific cranial nerve based on anatomical extent and distribution, which is foundational nervous system knowledge.

Question 44

Which part of the brain controls balance and coordination?

Accepted Answer

Answer reason: It fine-tunes voluntary motor activity by integrating proprioceptive, vestibular, and visual input to maintain posture, balance, and coordinated movements. Damage to this structure classically causes ataxia, dysmetria, and impaired gait stability. In contrast, the medulla primarily regulates vital autonomic functions (e.g., respiration, heart rate), and the thalamus mainly serves as a sensory relay and modulates cortical activation.
Category reason: This is a foundational question about brain structure-function relationships (which brain region controls balance and coordination), which falls under Neurology rather than nursing interventions or clinical prioritization.

Question 45

Functional unit of the nervous system is?

Accepted Answer

Answer reason: A) Neuron It is the basic structural and functional unit responsible for receiving, processing, and transmitting nerve impulses. The other choices are components or junctions related to this unit: axons conduct signals away from the cell body, dendrites receive input, and synapses are the communication points between cells. Therefore, the whole cell best represents the functional unit of the nervous system.
Category reason: This is a foundational question about the primary cellular unit of the nervous system, which is core neurobiology content rather than a nursing intervention or safety decision.

Question 46

A 42-year-old woman is admitted to the hospital with injury to the upper (superior) trunk of the brachial plexus. The diagnosis is Erb–Duchenne palsy. Which of the following conditions is expected to be present during physical examination?

Accepted Answer

Answer reason: Upper trunk (C5–C6) injury in Erb-Duchenne palsy affects nerves supplying deltoid and rotator cuff muscles, especially suprascapular and axillary contributions, leading to impaired shoulder abduction and external (lateral) rotation. Clinically this produces the classic “waiter’s tip” posture with the arm adducted and internally rotated. Winged scapula is more typical of long thoracic nerve injury, intrinsic hand muscle paralysis is seen with lower trunk (C8–T1/Klumpke) lesions, and dorsum-of-hand sensory loss is more consistent with radial nerve distribution rather than an upper trunk-predominant pattern.
Category reason: This item tests localization of a peripheral nerve plexus lesion (upper trunk brachial plexus) to expected motor deficits, which is primarily neuroanatomy/neurologic lesion-pattern recognition rather than nursing care decisions.

Question 47

Patient: 65-year-old female. Presentation: Progressive memory loss + confusion x6 months, difficulty managing finances, no head trauma. Possible Dx:

Accepted Answer

Answer reason: a) Alzheimer’s disease An insidious, progressive decline in recent memory and executive functioning (e.g., managing finances) over months is most consistent with a neurodegenerative dementia. Vascular dementia more often shows a stepwise decline with focal neurologic deficits and prominent vascular risk history. Depression (“pseudodementia”) can mimic cognitive impairment but typically features prominent mood symptoms and inconsistent effort, and hypothyroidism is a reversible cause but is less likely to present as a primary progressive dementia syndrome without other systemic hypothyroid features.
Category reason: This item tests recognition of dementia etiologies and clinical patterns (neurocognitive disorders), which is primarily foundational neurologic disease knowledge rather than nursing interventions or prioritization.

Question 48

Patient: 35-year-old male Presentation: High-grade fever + severe headache + neck stiffness x1 day. Vomiting present, photophobia. Possible Dx:

Accepted Answer

Answer reason: The combination of high-grade fever, severe headache, nuchal rigidity, photophobia, and vomiting is classic for acute meningitis due to meningeal inflammation. Viral flu typically causes systemic symptoms without prominent neck stiffness/meningismus. Migraine may cause photophobia and vomiting but would not explain high fever and neck stiffness. Encephalitis more often features altered mental status, seizures, or focal neurologic deficits, which are not described here.
Category reason: This item tests recognition of a neurologic infectious syndrome (meningeal irritation signs) and differentiating it from other neurologic/viral conditions, which fits Neurology.

Question 49

Bell's Palsy is due to Paralysis of?

Accepted Answer

Answer reason: Bell’s palsy is an acute, typically unilateral lower motor neuron facial weakness caused by dysfunction of cranial nerve VII. CN VII supplies the muscles of facial expression, so its palsy produces inability to close the eye, flattening of the nasolabial fold, and drooping of the mouth on the affected side. It may also reduce lacrimation, salivation, and taste from the anterior two-thirds of the tongue due to associated parasympathetic and sensory fibers. Other listed nerves primarily mediate swallowing/viscera (vagus), facial sensation/mastication (trigeminal), or vision (optic) rather than facial motor function.
Category reason: This is a foundational question about which cranial nerve is affected in Bell’s palsy, testing neuroanatomy/neurologic function rather than nursing interventions, so it fits Neurology in NursingScience.

Question 50

Patient: 25-year-old female Presentation: Severe headache ×1 week, throbbing, photophobia, mild nausea, no fever or vision changes. Possible Dx:

Accepted Answer

Answer reason: Throbbing headache with photophobia and nausea is most characteristic of migraine. The absence of fever and focal sinus symptoms makes sinusitis less likely, and lack of “band-like” pressure without photophobia argues against tension headache. Cluster headache typically presents with unilateral severe periorbital pain and prominent autonomic symptoms (e.g., lacrimation, rhinorrhea), which are not described here.
Category reason: This item tests recognition of classic headache syndrome features (migraine vs tension vs cluster vs sinusitis), which is primarily neurologic disease pattern identification rather than a nursing intervention or prioritization scenario.
