Question 1

What is the largest joint in the human body?

Accepted Answer

Answer reason: The knee is considered the largest joint in the human body based on its overall size and complex articulations between the femur, tibia, and patella. It is a large synovial hinge joint with extensive articular surfaces and strong supporting ligaments and menisci. While the hip is a major weight-bearing joint, it is not typically classified as the largest; the knee holds that distinction. "Pivot" describes a type of synovial joint rather than a specific body joint location.
Category reason: This question tests identification of a major human joint and comparative anatomy (largest joint), which is foundational structural knowledge in Anatomy rather than a nursing intervention or clinical judgment task.

Question 2

THE THIRD MOLARS IN A HUMAN BEING ARE COMMONLY KNOWN BY WHAT NAME?

Accepted Answer

Answer reason: Third molars are the most posterior teeth in each quadrant and typically erupt in late adolescence or early adulthood, which is why they are commonly called "wisdom teeth." Canine teeth are the pointed cuspid teeth located anteriorly, and "cutting teeth" generally refers to incisors. Therefore, the correct common name for third molars is wisdom teeth.
Category reason: This item tests identification of a specific tooth type (third molars) and its common anatomical name, which is a basic oral/dental anatomy concept rather than a nursing intervention or clinical judgment scenario.

Question 3

What is the anatomical name of windpipe?

Accepted Answer

Answer reason: The windpipe is the trachea, the airway tube that conducts air from the larynx to the bronchi and lungs. The spleen is a lymphatic organ, the abdomen is a body region, and the esophagus (spelled incorrectly as "Osophagus" here) is part of the gastrointestinal tract that carries food to the stomach. Therefore, "Trachea" is the only correct anatomical term for windpipe.
Category reason: This item tests identification of a specific body structure (the windpipe) and its correct anatomical name, which is a foundational Anatomy concept rather than a nursing care decision.

Question 4

The number of floating ribs in the human body, is?

Accepted Answer

Answer reason: Humans typically have 12 pairs of ribs: 7 true ribs (pairs 1–7) that attach directly to the sternum, 3 false ribs (pairs 8–10) that attach indirectly via costal cartilage, and 2 floating ribs (pairs 11–12) that have no anterior attachment to the sternum. Therefore, the number of floating ribs is 2 pairs. The other options overestimate the count of ribs without sternal attachment.
Category reason: This is a foundational question about the classification and number of ribs in the human skeleton, which is core content in Anatomy rather than a nursing care/intervention decision.

Question 5

A patient had injury to humerus, Surgical neck of humerus damaged, which nerve damage likely?

Accepted Answer

Answer reason: The axillary nerve courses around the surgical neck of the humerus with the posterior circumflex humeral artery, making it the nerve most vulnerable in fractures or injury at this location. Injury can lead to deltoid and teres minor weakness (impaired shoulder abduction and external rotation). Sensory loss may occur over the “regimental badge” area on the lateral shoulder. Radial nerve injury is more typical with midshaft humeral fractures in the radial groove.
Category reason: This question tests anatomical relationships between a specific bony landmark (surgical neck of humerus) and the peripheral nerve that runs adjacent to it, which is core Upper Limb Anatomy rather than nursing care decision-making.

Question 6

The study of structure of the human body is called?

Accepted Answer

Answer reason: Anatomy is the scientific study of the structure of the human body, including the organization of organs, tissues, and body regions. Physiology focuses on function (how body parts work), not structure. Pathology studies disease processes and structural/functional changes caused by disease. Histology is a subfield of anatomy focused specifically on microscopic tissue structure rather than overall body structure.
Category reason: This item tests foundational knowledge of what the discipline of anatomy studies (body structure), which is a core biomedical science topic rather than a nursing care decision.

Question 7

The muscle of injection in Shoulder is called?

Accepted Answer

Answer reason: The standard intramuscular injection site in the shoulder region is the deltoid muscle. It is superficial and easily accessible, allowing safe deposition of small to moderate IM volumes when landmarked correctly. The biceps and triceps are not the preferred shoulder IM sites because of less consistent landmarking and higher risk of neurovascular injury compared with the deltoid.
Category reason: This item tests identification of the correct muscle in the shoulder used for IM injections, which is a structural/location question about the human body and therefore belongs to Anatomy.

Question 8

Scapula is an example of?

Accepted Answer

Answer reason: The scapula (shoulder blade) is classified as a flat bone because it is thin, broad, and primarily composed of two layers of compact bone with spongy bone between. Flat bones provide wide surfaces for muscle attachment and help protect underlying structures. In contrast, long bones (e.g., femur) are elongated, short bones (e.g., carpals) are cube-like, and irregular bones (e.g., vertebrae) have complex shapes.
Category reason: This question tests classification of a skeletal structure (scapula) by bone type, which is core content in human Anatomy rather than nursing decision-making or patient-care interventions.

Question 9

The total number of bones in the human skull is?

Accepted Answer

Answer reason: The adult human skull is classically described as having 22 bones: 8 cranial bones (neurocranium) and 14 facial bones (viscerocranium). This count excludes the auditory ossicles (6) and the hyoid bone, which are sometimes discussed separately. Therefore, among the options provided, 22 is the correct total number of skull bones.
Category reason: This question tests recall of the standard anatomical count of skull bones, which is a core Anatomy concept rather than a nursing care decision.

Question 10

Pituitary gland is located in?

Accepted Answer

Answer reason: The pituitary gland sits in the hypophyseal fossa of the sella turcica of the sphenoid bone at the base of the skull. It is connected to the hypothalamus by the infundibulum, but it is not located within the hypothalamus itself. The brainstem and cerebellum are posterior fossa structures and are not the anatomical seat of the pituitary.
Category reason: This question tests the anatomical location of an endocrine gland (pituitary) within cranial bony landmarks (sella turcica), which is a core Anatomy topic rather than a nursing intervention or clinical judgment scenario.

Question 11

Digestive system ends at:

Accepted Answer

Answer reason: The digestive (gastrointestinal) tract begins at the mouth and terminates at the anus, which is the external opening where feces exit the body. The rectum and colon are internal segments proximal to the anus and therefore are not the endpoint. The ileum is part of the small intestine and is much earlier in the GI tract than the terminal end.
Category reason: This item tests basic structural knowledge of the gastrointestinal tract (where it terminates), which is an anatomy concept rather than a nursing intervention or clinical judgment scenario.

Question 12

Which is the first permanent tooth to erupt in children?

Accepted Answer

Answer reason: The first permanent teeth to erupt are typically the first molars (often called the “6-year molars”), emerging around age 6 behind the primary second molars. The permanent central incisors usually erupt slightly later (about 6–7 years), followed by lateral incisors and canines later still. Therefore, among the options, the first molar is the earliest permanent tooth to erupt.
Category reason: The question tests knowledge of the normal eruption sequence of permanent dentition, which is an anatomical/developmental concept rather than a nursing intervention or patient-care decision.

Question 13

Which diaphragm is a?

Accepted Answer

Answer reason: The diaphragm is a dome-shaped skeletal muscle that separates the thoracic and abdominal cavities. When it contracts, it flattens and increases thoracic volume, creating negative pressure to draw air into the lungs. It is not a gland (no secretory function) and not a bone; while it is an anatomical structure, its tissue type is muscle.
Category reason: This item tests basic structural identification of the diaphragm and its tissue type, which is foundational human anatomy rather than nursing care decision-making.

Question 14

Haversian canal situated into:

Accepted Answer

Answer reason: The Haversian (central) canal is the central channel of an osteon in compact bone. It contains blood vessels and nerves that supply the concentric lamellae and osteocytes via canaliculi. Brain, lungs, and kidney do not have Haversian systems; these are specific to the microscopic structure of compact bone.
Category reason: This tests identification of a microscopic structural feature (Haversian canal/osteon) and where it is found, which is a core Anatomy concept rather than a nursing intervention or clinical judgment topic.

Question 15

The tailbone is called?

Accepted Answer

Answer reason: The tailbone is anatomically termed the coccyx, which is the terminal segment of the vertebral column. It consists of several (typically 3–5) fused coccygeal vertebrae. The sacrum lies superior to the coccyx, while the sternum is in the thorax and the patella is the kneecap, making them incorrect.
Category reason: This is a direct identification of a body structure (the anatomical name of the tailbone), which is a foundational Anatomy concept rather than a nursing judgment or intervention.

Question 16

Q- The longest nerve in the human body is?

Accepted Answer

Answer reason: The sciatic nerve is the largest and longest nerve in the human body, arising from the lumbosacral plexus and traveling from the pelvis through the posterior thigh to the lower leg via its branches (tibial and common fibular). Its extensive course to the foot makes it longer than cranial nerves such as the optic, vagus, or facial nerves. Therefore, among the given options, the sciatic nerve is the best answer.
Category reason: This item tests factual knowledge of human nerve anatomy (which nerve is longest), making it primarily an Anatomy question rather than a nursing judgment or intervention problem.

Question 17

Human teeth are called?

Accepted Answer

Answer reason: Humans have different types of teeth—incisors, canines, premolars, and molars—each specialized for cutting, tearing, and grinding. Dentitions with multiple tooth forms are termed heterodont. In contrast, homodont dentition refers to teeth that are all similar in shape, as seen in many reptiles and fish. Therefore, the correct term for human teeth is heterodont.
Category reason: This is a foundational classification of tooth types (heterodont vs homodont), which is part of structural anatomy of the oral cavity rather than a nursing care/intervention decision.

Question 18

What type of bone is the sternum?

Accepted Answer

Answer reason: The sternum is classified as a flat bone because it is thin, flattened, and provides broad surface area for muscle attachment and protection. Flat bones also contain diploë (spongy bone) between layers of compact bone and often contribute to hematopoiesis. Functionally, the sternum protects thoracic organs by forming the anterior portion of the rib cage.
Category reason: This question tests classification of a specific skeletal structure (sternum) by bone type, which is a foundational Anatomy concept rather than a nursing intervention or clinical judgment scenario.

Question 19

Voice is Produced by?

Accepted Answer

Answer reason: Voice is produced in the larynx, where the vocal cords (vocal folds) vibrate as air passes through the glottis to create sound. The pharynx helps with resonance but does not generate the primary sound. The trachea functions mainly as an airway conduit, and the alveoli are for gas exchange. Therefore, the best answer is the larynx (spelled in the option as "Laxynx").
Category reason: This question tests knowledge of the anatomical structure responsible for phonation (voice production), which is a core concept in human anatomy rather than a nursing care decision.

Question 20

Metamerism is found in..?

Accepted Answer

Answer reason: Metamerism refers to true segmentation of the body into a series of similar, repeated units (metameres), which is characteristic of annelids. Earthworm (an annelid) shows clear external and internal segmentation with repeated organ systems across segments. Frog and butterfly do not have true metameric segmentation, and Sycon (a sponge) lacks organized segmentation altogether.
Category reason: The question tests recognition of a structural body plan feature (segmentation/metamerism) across organisms, which is a foundational anatomy/zoology concept rather than a nursing care decision.

Question 21

What type of bone is the vertebrae?

Accepted Answer

Answer reason: Vertebrae have complex shapes with multiple projections (spinous and transverse processes) and a vertebral body that do not fit the typical structure of long, short, or flat bones. Because of this non-uniform, specialized architecture, they are classified as irregular bones. This shape supports protection of the spinal cord and provides multiple muscle and ligament attachment points.
Category reason: The question tests classification of bone types (long, short, flat, irregular), which is a foundational topic in skeletal anatomy rather than a nursing-care decision.

Question 22

What Connects the brain and Spinal Cord?

Accepted Answer

Answer reason: The medulla oblongata is the inferior part of the brainstem and is continuous with the spinal cord at the foramen magnum, serving as the direct anatomical connection between brain and spinal cord. The hippocampus is a limbic structure involved in memory, not a connecting segment. The cerebellum coordinates movement and balance and does not form the brain–spinal cord junction. Therefore, among the options, medulla is the best answer.
Category reason: This item tests identification of a central nervous system structure and its anatomical relationship to the spinal cord, which is primarily Anatomy (foundational biomedical knowledge) rather than a nursing intervention or judgment task.

Question 23

The number of human spinal nerves is?

Accepted Answer

Answer reason: Humans have 31 pairs of spinal nerves arising from the spinal cord (8 cervical, 12 thoracic, 5 lumbar, 5 sacral, and 1 coccygeal). Each pair includes a left and right spinal nerve, so 31 pairs equals 62 individual spinal nerves. This is distinct from cranial nerves, which are 12 pairs. Therefore, among the options, 62 is correct.
Category reason: This question tests recall of the number and grouping of spinal nerves, a foundational structural fact about the nervous system and spine, which is primarily Anatomy rather than a nursing-care decision.

Question 24

How many pairs of ribs are there in the human body?

Accepted Answer

Answer reason: Humans typically have 12 pairs of ribs (24 ribs total). These attach posteriorly to the thoracic vertebrae, with the first 7 pairs connecting directly to the sternum (true ribs), ribs 8–10 connecting indirectly (false ribs), and ribs 11–12 not attaching anteriorly (floating ribs). Although anatomical variants can occur (e.g., cervical ribs), the standard count is 12 pairs.
Category reason: This question tests basic structural knowledge of the human skeletal system (rib count), which is a core topic in Anatomy rather than a nursing care decision.

Question 25

Total bones of new born baby is ________?

Accepted Answer

Answer reason: A newborn has more bones than an adult because many skeletal elements (especially in the skull, pelvis, and long bones) are initially separate and later fuse during growth. The commonly taught approximate count at birth is about 300–305 bones, decreasing to 206 in adulthood with fusion. Among the given options, 305 is the best match for the standard newborn bone count approximation. The other choices are either the adult count (206) or implausibly high for typical human anatomy (350).
Category reason: This question tests a factual count about the human skeletal system (number of bones at birth versus adulthood), which is foundational structural knowledge in Anatomy rather than a nursing care decision.

Question 26

Human body consist of ---------- bones

Accepted Answer

Answer reason: The typical adult human skeleton contains 206 bones. Newborns have more bones (about 270–300) that later fuse during growth (e.g., skull bones, sacrum, coccyx). Therefore, among the options, 206 is the correct count for an adult human body.
Category reason: This question tests a basic fact about the number of bones in the human skeleton, which is core content in Anatomy rather than nursing decision-making or patient-care prioritization.

Question 27

Number of Thoracic vertebra in human is?

Accepted Answer

Answer reason: Humans typically have 12 thoracic vertebrae (T1–T12). These vertebrae articulate with the 12 pairs of ribs, forming the thoracic cage. The other options do not match the standard vertebral segmentation of the human spine.
Category reason: This item tests recall of the normal number of vertebrae in a spinal region, which is a core concept in human skeletal anatomy.

Question 28

Phrenic nerve supplies the sensation to all but

Accepted Answer

Answer reason: The phrenic nerve (C3–C5) carries sensory fibers from the fibrous pericardium, mediastinal pleura, and the central diaphragmatic pleura and peritoneum, as well as motor supply to the diaphragm. Thus, it is involved in sensation from the diaphragm and related serous membranes (including central peritoneum) and pericardium. The left ventricle itself is not a structure whose sensation is supplied by the phrenic nerve; cardiac visceral pain afferents travel mainly with sympathetic fibers (and some reflex afferents with the vagus). Therefore, the exception is the left ventricle.
Category reason: This tests anatomical innervation (phrenic nerve sensory distribution) rather than nursing interventions or clinical decision-making, so it belongs to Anatomy within NursingScience.

Question 29

What is the longest bone in the human body?

Accepted Answer

Answer reason: The femur (thigh bone) is the longest and strongest bone in the human body, extending from the hip to the knee. It bears significant body weight and has the greatest overall length compared with other long bones. The humerus, tibia, and fibula are long bones but are shorter than the femur.
Category reason: This question tests knowledge of human skeletal structures and comparative bone anatomy, which falls under Anatomy.

Question 30

How many facial bones does the skull possess?

Accepted Answer

Answer reason: The human facial skeleton consists of 14 bones. These include paired bones (nasal, lacrimal, zygomatic, maxillae, palatine, inferior nasal conchae) plus two unpaired bones (mandible and vomer). Together, they form the framework of the face, orbits, and nasal and oral cavities.
Category reason: This question tests recall of the number of facial bones of the skull, which is a core topic in human skeletal anatomy rather than nursing judgment or intervention.

Question 31

How many bones present in human ear?

Accepted Answer

Answer reason: The human middle ear contains three ossicles: the malleus, incus, and stapes. These small bones transmit sound vibrations from the tympanic membrane to the oval window of the inner ear. Therefore, the correct count of ear bones (ossicles) is three.
Category reason: This question tests factual knowledge of the structures (bones/ossicles) of the ear, which is a core topic in anatomy rather than nursing clinical judgment or patient-care decision-making.

Question 32

How many Teeth of Human?

Accepted Answer

Answer reason: The normal number of permanent (adult) human teeth is 32, which includes 8 incisors, 4 canines, 8 premolars, and 12 molars (including the third molars/wisdom teeth). Primary (deciduous) teeth total 20, but the question asks generally for human teeth and the standard answer refers to adult dentition. Therefore, 32 is the best answer among the choices.
Category reason: This question tests factual knowledge of the normal number of human teeth, which is an anatomical concept related to dentition rather than a nursing care decision.

Question 33

________ Is the study of different organs of body know as?

Accepted Answer

Answer reason: The study of different organs and body structures is called anatomy. Pathology is the study of disease processes, oncology focuses on cancer, and physiology studies how body systems function rather than primarily their structures. Since “Anatomy” is not listed among the options, the best available choice is “Non Of Above.”.
Category reason: This item asks for the term describing the study of body organs/structures, which is a foundational structural science concept belonging to Anatomy.

Question 34

All of the following are lobes of the cerebrum EXCEPT?

Accepted Answer

Answer reason: The cerebrum is divided into lobes including the frontal, parietal, temporal, and occipital lobes. The cerebellum is a separate major brain structure located posterior-inferior to the cerebrum and is not a lobe of the cerebrum. Therefore, "Cerebellar" is the exception among the listed choices.
Category reason: This question tests identification of major brain structures and which named regions are cerebral lobes, which is a foundational topic in gross neuroanatomy rather than nursing clinical decision-making.

Question 35

Which bone is also known as the "funny bone"?

Accepted Answer

Answer reason: The "funny bone" sensation occurs when the ulnar nerve is struck at the medial elbow (cubital tunnel). This nerve runs in a groove adjacent to the medial epicondyle of the humerus, so impact to this area produces tingling down the forearm and into the hand. Although the nerve is ulnar, the commonly tested bone associated with the "funny bone" is the humerus at the elbow.
Category reason: This item tests identification of a skeletal structure and its common anatomical association at the elbow, which is a foundational Anatomy concept rather than a nursing care intervention.

Question 36

How many cervical vertebrae are present in humans?

Accepted Answer

Answer reason: Humans have 7 cervical vertebrae (C1–C7) in the neck region of the vertebral column. C1 (atlas) and C2 (axis) are specialized for head support and rotation, while C3–C7 provide additional support and protect the spinal cord. The other options correspond to different spinal regions (e.g., 12 thoracic vertebrae).
Category reason: This item tests recall of the number of vertebrae in the cervical spine, which is a core concept of human skeletal anatomy rather than nursing judgment or interventions.

Question 37

The part of the ear that collects sound is?

Accepted Answer

Answer reason: The pinna (auricle) is the external visible part of the ear that collects and funnels sound waves into the external auditory canal. The cochlea is involved in transducing vibrations into nerve impulses, not collecting sound. The eardrum (tympanic membrane) vibrates in response to sound, and the ossicles transmit these vibrations to the inner ear. Therefore, the structure that collects sound is the pinna.
Category reason: This is a structural identification question about which ear part performs a specific function (collecting sound), which is primarily covered under Anatomy.

Question 38

Parotid gland

Accepted Answer

Answer reason: The facial nerve traverses the parotid gland (forming the parotid plexus) but does not provide secretomotor supply to the gland. Parasympathetic secretomotor innervation to the parotid comes from the glossopharyngeal nerve (CN IX) via the lesser petrosal nerve to the otic ganglion and then via the auriculotemporal nerve (V3). Therefore, the statement that the facial nerve supplies the gland is incorrect and is the best choice if the item is asking for the false statement about the parotid gland. In contrast, the parotid is the largest salivary gland and its duct opens opposite the upper second molar.
Category reason: This question tests structural and innervation facts about salivary glands (location and nerve supply), which is foundational head-and-neck anatomy rather than a nursing care decision.

Question 39

What is the anatomical name for the wrist joint?

Accepted Answer

Answer reason: The wrist joint is anatomically referred to as the radiocarpal joint, formed primarily between the distal radius and the proximal carpal bones (especially the scaphoid and lunate). The carpometacarpal joint is between the carpal bones and metacarpals (e.g., thumb base). The metacarpophalangeal and proximal interphalangeal joints are finger joints, not the wrist.
Category reason: This question tests identification of the correct anatomical term for a joint and distinguishes wrist anatomy from hand and finger joints, which is core Anatomy content rather than nursing intervention/decision-making.

Question 40

Which of the following structures is located anterior to the vagina?

Accepted Answer

Answer reason: In female pelvic anatomy, the vagina lies posterior to the urethra and the urinary bladder. The rectum, sacrum, and coccyx are posterior structures relative to the vagina. Therefore, the urethra and bladder are the structures located anterior to the vagina.
Category reason: This question tests spatial relationships of female pelvic organs, which is an Anatomy concept rather than a nursing intervention or clinical decision-making scenario.

Question 41

The longest bone in the body is?

Accepted Answer

Answer reason: The femur (thigh bone) is the longest and strongest bone in the human body, extending from the hip to the knee. The tibia is the longest bone of the lower leg but is shorter than the femur. The humerus and ulna are upper-limb bones and are also shorter than the femur. Therefore, the femur is the single best answer.
Category reason: This question tests identification of a human skeletal structure (which bone is longest), a core topic in Anatomy rather than nursing care decision-making.

Question 42

A plane that passes through the midline of the body and divides it into equal right and left sides is called?

Accepted Answer

Answer reason: The midsagittal (median) plane runs vertically through the body’s midline, creating equal right and left halves. A parasagittal plane is parallel to the midsagittal plane but does not divide the body into equal halves. The coronal plane divides the body into anterior and posterior portions, while an oblique plane cuts at an angle.
Category reason: This question tests knowledge of anatomical body planes used to describe location and sectioning of the body, which is a core Anatomy concept rather than a nursing intervention or clinical judgment item.

Question 43

Number of milk teeth of is?

Accepted Answer

Answer reason: Primary (deciduous/milk) dentition consists of 20 teeth total: 8 incisors, 4 canines, and 8 molars. These erupt in early childhood and are later replaced by the permanent teeth. Therefore the correct count of milk teeth is 20, making option C the best answer.
Category reason: This question tests factual knowledge of human dentition and tooth count, which is a basic structural detail of the body studied under Anatomy rather than a nursing intervention or clinical judgment scenario.

Question 44

The heart is located in which cavity of the human body?

Accepted Answer

Answer reason: The heart is located in the thoracic cavity, specifically within the mediastinum between the lungs and above the diaphragm. The abdominal and pelvic cavities contain digestive and reproductive/urinary organs, respectively. The cranial cavity contains the brain, not the heart.
Category reason: This question tests the anatomical location of an organ within body cavities, which is a core Anatomy concept rather than a nursing intervention or clinical judgment scenario.

Question 45

Total number of bone found in skull..

Accepted Answer

Answer reason: The human skull (cranium) contains 8 cranial bones: frontal, occipital, sphenoid, ethmoid, and paired parietal and temporal bones. These are distinct from the 14 facial bones, which are counted separately. Therefore, the correct total number of cranial bones is 8.
Category reason: This question tests recall of skeletal structures and bone counts in the skull, which is a core topic in human anatomy rather than nursing care decision-making.

Question 46

Which neck muscle allows rotation and flexion of the head?

Accepted Answer

Answer reason: The sternocleidomastoid flexes the neck (bilateral contraction) and rotates the head to the opposite side (unilateral contraction). This directly matches the stem asking for rotation and flexion of the head. The deltoid acts primarily on the shoulder, the masseter elevates the mandible for chewing, and the trapezius mainly moves the scapula and extends the neck rather than being the primary head rotator/flexor tested here.
Category reason: This is a foundational question about identification and function of a specific muscle, which is primarily tested in Anatomy rather than nursing clinical judgment or patient-care decision-making.

Question 47

Largest organ in human body is?

Accepted Answer

Answer reason: The skin is the largest organ of the human body by surface area and overall mass. It provides a protective barrier, helps regulate temperature, enables sensation, and contributes to immune defense and vitamin D synthesis. The liver is the largest internal organ, but not the largest organ overall. The heart and brain are vital organs but are smaller than the skin.
Category reason: This item tests basic knowledge of human organs and which is largest, which is a foundational anatomy concept rather than a nursing intervention or clinical decision-making scenario.

Question 48

The largest intestine ends in :

Accepted Answer

Answer reason: The large intestine continues from the cecum through the ascending, transverse, descending, and sigmoid colon, and then terminates in the rectum (followed by the anal canal to the anus). The stomach and duodenum are parts of the upper gastrointestinal tract, not the termination of the large intestine. The ileum is the terminal part of the small intestine and connects to the large intestine at the ileocecal valve.
Category reason: This is a structural question about where the large intestine terminates, which is primarily tested as gross anatomy of the gastrointestinal tract rather than nursing interventions or clinical judgment.

Question 49

The wrist contains how many small bones called carpals?

Accepted Answer

Answer reason: The carpus (wrist) is made up of 8 carpal bones arranged in two rows of four: scaphoid, lunate, triquetrum, pisiform; and trapezium, trapezoid, capitate, hamate. This is a standard anatomical fact used to describe wrist structure and common injury patterns. Therefore, the correct count is 8.
Category reason: This question tests recall of the number of carpal bones in the wrist, which is a musculoskeletal structural fact and belongs to Anatomy rather than nursing care decision-making.

Question 50

In which phylum is the body cavity pseudocoelomate?

Accepted Answer

Answer reason: Pseudocoelomates have a body cavity not completely lined by mesoderm (a pseudocoelom). This is characteristic of roundworms in the phylum Nematoda. In contrast, Annelida, Arthropoda, and Echinodermata are true coelomates with a coelom fully lined by mesoderm (though arthropods have a reduced coelom with a hemocoel as the main body cavity).
Category reason: The question tests classification of animal body cavity types (pseudocoelomate vs coelomate) across phyla, which is foundational structural biology/anatomy rather than nursing care or clinical decision-making.
