Question 1

The school nurse assesses a young child with a rash that’s raised and has circumscribed areas filled with fluid. The nurse documents this finding as which type of rash?

Accepted Answer

Answer reason: This morphology distinguishes vesicular eruptions (e.g., varicella, herpes simplex) from solid elevated lesions. Papules are raised but contain no fluid, macules are flat discolorations, and petechiae are small nonblanching hemorrhagic spots rather than fluid-filled lesions. Therefore the nurse should document the finding using vesicular terminology.

Question 2

A nurse is assessing a client recently admitted to the hospital and observes hair loss in small round circles on the client’s scalp. The nurse documents this assessment finding as?

Accepted Answer

Answer reason: Patchy, well-circumscribed round areas of hair loss on the scalp are characteristic of alopecia (classically alopecia areata). The term describes hair loss regardless of cause and is the correct documentation term for this assessment finding. Amblyopia and exotropia are eye disorders (decreased vision and outward eye deviation, respectively) and do not describe scalp findings. Seborrhea refers to excessive sebum/oily scaling of the skin or scalp rather than discrete circular hair loss.

Question 3

The nurse is assessing the client. Which findings should the nurse associate with herpes zoster?

Accepted Answer

Answer reason: The typical primary lesions are grouped vesicles on an erythematous base that are painful and may also itch as they evolve and crust. Purulent drainage suggests secondary bacterial infection rather than the primary viral presentation. Petechiae or primarily macular lesions are not the characteristic morphology for shingles.

Question 4

Which finding should the nurse expect to observe if a child has papules?

Accepted Answer

Answer reason: This description matches a raised lesion that can be felt on examination. In contrast, fluid-filled elevations describe vesicles or bullae, and nonpalpable flat color changes describe macules. Loss of the epidermal layer reflects erosions/ulcers rather than a papular lesion.

Question 5

A mother of a toddler diagnosed with atopic dermatitis is concerned about how her child acquired the disease. The best response by the nurse is?

Accepted Answer

Answer reason: Atopic dermatitis is a chronic inflammatory skin condition strongly associated with genetic predisposition and family history of atopy (eczema, asthma, allergic rhinitis). It is not “caught” from another person and is therefore not explained by a fungal or viral infection as a primary cause. The underlying problem involves impaired skin barrier function and immune dysregulation, which leads to xerosis and pruritic eczematous lesions. While secondary infection can occur from scratching, that is a complication rather than the way the child acquired the condition. The most accurate, reassuring teaching response is to frame it as a condition with hereditary tendency.

Question 6

The nurse is assessing a 6-year-old child with a spiny projection from the skin suspended from a narrow stalk on the forehead. Which condition would the nurse suspect?

Accepted Answer

Answer reason: g., around the mouth, nose, or forehead) in children. The described morphology—spiny projection suspended from a narrow stalk—fits this classic presentation. Flat warts are typically smooth, slightly elevated, and flat-topped rather than stalked and spiny. Plantar warts occur on the soles and tend to be endophytic and painful with pressure, while venereal warts are located in the anogenital region and are not the expected finding on a child’s forehead.

Question 7

A client arrives at the office of his physician complaining of a rash. The nurse assesses the client and notes several palpable, elevated masses, each about 0.5 cm. The nurse documents these assessment findings using which term?

Accepted Answer

Answer reason: The key descriptors here are “palpable” and “elevated,” which indicate a raised lesion rather than a flat color change. Macules are flat/nonpalpable, vesicles are raised but fluid-filled, and erosions represent superficial loss of epidermis rather than a discrete elevated mass. A 0.5 cm raised lesion therefore best matches a papule.

Question 8

The child has a tentative diagnosis of Albright's disease (neurofibromatosis). When assisting the child to disrobe prior to a physical exam, what should the nurse expect to observe?

Accepted Answer

Answer reason: These hyperpigmented macules are typically present in childhood and are a key screening observation during a skin exam when the condition is suspected. The other options describe infestations, environmental exposures, or unrelated pigmented lesions that are not hallmark findings of neurofibromatosis. Recognizing these lesions supports timely referral for further evaluation of associated neurologic/ocular complications.

Question 9

A 3-month-old infant is noted to have café-au-lait spots on examination. The presence of six or more of these lesions with a diameter greater than 1.5 cm is suggestive of which disorder?

Accepted Answer

Answer reason: NF1 is a neurocutaneous disorder in which increased melanin deposition produces these well-circumscribed light-brown patches early in life, often before other findings emerge. The question’s threshold of ≥6 lesions of significant size aligns with established diagnostic features prompting evaluation for NF1 and associated complications (e.g., optic pathway glioma, skeletal abnormalities). Meningococcemia typically presents with acute systemic illness and petechiae/purpura rather than stable hyperpigmented macules. Tinea versicolor causes hypo- or hyperpigmented scaly patches, and vitiligo causes depigmented patches, neither matching café-au-lait criteria.

Question 10

A child presents with pustules and is diagnosed with impetigo. The nurse documents which assessment findings?

Accepted Answer

Answer reason: A pustule is defined as a small, circumscribed elevation of the skin containing purulent material, matching the child’s presentation. The serous-filled lesion options describe vesicles (0.5 cm), which are fluid-filled rather than purulent. Localized edema (wheal) is more consistent with urticaria or allergic reactions than impetigo’s primary lesion type.

Question 11

A neonate is examined and noted to have bruising on the scalp, along with diffuse swelling of the soft tissue that crosses over the suture line. The nurse most accurately interprets these findings as?

Accepted Answer

Answer reason: The key diagnostic principle is whether neonatal scalp swelling crosses suture lines, which reflects the anatomic layer involved. Caput succedaneum is superficial (in the scalp soft tissues), causing diffuse edema/ecchymosis that can cross suture lines and is commonly related to pressure during labor. Cephalohematoma is subperiosteal bleeding that is confined by periosteal attachments, so it does not cross suture lines and may contribute to hyperbilirubinemia as it resolves. Craniotabes describes soft skull bones with a “ping-pong” feel, and hydrocephalus presents with enlarged head circumference and fontanel changes rather than localized bruised scalp edema.

Question 12

During a physical examination, a child is noted to have nails with “icepick” pits and ridges. The nails are thick and discolored and have splintered hemorrhages easily separated from the nail bed. Which condition would cause this to occur?

Accepted Answer

Answer reason: Onycholysis with subungual hyperkeratosis can make the nail plate lift and separate more easily from the nail bed. Splinter hemorrhages can occur from capillary fragility/trauma in inflamed nail bed tissue. Paronychia is an acute infection of the nail folds, while scabies and seborrhea primarily affect skin and do not produce this characteristic nail pitting pattern.

Question 13

The nurse is caring for a client who has thick, discolored nails that have “ice pick” pits and ridges and splintered hemorrhages and that easily separate from the nail bed. The nurse explains to the client that these findings are associated with which condition?

Accepted Answer

Answer reason: These findings reflect abnormal keratinization and inflammation in the nail matrix/bed, which directly matches the described nail changes. Paronychia is primarily an infection/inflammation of the nail folds rather than matrix-driven pitting and onycholysis. Seborrhea and scabies typically present with scalp/skin scaling or pruritic burrows, not the characteristic pitted, dystrophic nails described.

Question 14

A client is admitted with suspected malignant melanoma on his left shoulder. During the physical assessment, the nurse would anticipate observing?

Accepted Answer

Answer reason: Malignant melanoma is suspected when a pigmented lesion shows concerning ABCDE changes, especially variegated color within the same lesion. The presence of multiple colors (e.g., brown/black with red, white, or blue) reflects irregular melanin distribution and possible regression or ulceration, which are classic warning signs. In contrast, a birthmark that lightens is generally less concerning for melanoma progression, and petechiae suggests a bleeding or platelet disorder rather than a skin cancer lesion. A darkening red birthmark is more consistent with vascular lesion changes than with melanoma’s typical pigmented, color-variegated presentation.

Question 15

A nurse educator is teaching a group of clients about hygiene. Which statement by a client indicates the need for further teaching?

Accepted Answer

Answer reason: "Intact skin primarily functions as a barrier that limits water and chemical absorption rather than broadly absorbing fluids. While certain substances (especially lipid-soluble medications) can be absorbed transdermally, routine “fluid absorption” is not a normal hygiene-related function of healthy skin. In contrast, the skin’s protective role against pathogens, its excretion of small amounts of wastes via sweat, and its role in vitamin D synthesis are well-established physiologic functions. Therefore this statement reflects a misunderstanding and indicates a need for further teaching.

Question 16

Which skin condition is characterized by erythematous plaques with an adherent silvery scale usually appearing over the extensor surfaces of the extremities, including lesions on the palms, soles, scalp, umbilicus, and genital areas?

Accepted Answer

Answer reason: Silvery, adherent scale on well-demarcated erythematous plaques is classic for a chronic inflammatory papulosquamous disorder driven by keratinocyte hyperproliferation and immune dysregulation. The extensor distribution (elbows, knees) and frequent involvement of scalp, umbilicus, and genital areas strongly supports this diagnosis, and palm/sole disease can occur in certain variants. Impetigo typically presents with honey-colored crusted lesions from bacterial infection rather than thick silvery scale. Molluscum contagiosum causes umbilicated pearly papules, and pityriasis rosea commonly shows a herald patch with a “Christmas tree” trunk distribution, not extensor plaques with silvery scale.

Question 17

The nurse is teaching a client how to care for his skin. The nurse determines that the client understands teaching about sebum when the client makes which statement?

Accepted Answer

Answer reason: Sebum is an oily lipid-rich substance produced by sebaceous glands and released into hair follicles to lubricate and help waterproof the skin and hair. This function supports maintaining skin barrier integrity and reducing excessive dryness and friction. The other options describe skin layers (epidermis/dermis/subcutaneous tissue) or the structure of a hair follicle, not the gland secretion itself. Therefore the statement identifying sebum as the skin’s oil indicates correct understanding.

Question 18

The nurse is assessing a 30-year-old client admitted to the emergency department with a deep partial-thickness burn on his arm after a fire in the workplace. The nurse documents the assessment findings as?

Accepted Answer

Answer reason: Deep partial-thickness burns extend beyond the epidermis into the dermis, destroying much of the dermal layer while sparing some dermal structures that allow re-epithelialization. Clinically they can appear pale/mottled and are often very painful due to exposed nerve endings, but the defining feature is depth into the dermis. Full-thickness burns instead involve destruction through the entire dermis and can extend into subcutaneous tissue, which aligns with necrosis through all layers. Superficial burns are limited to the epidermis and present mainly with erythema and pain, making them inconsistent with a deep partial-thickness injury.

Question 19

When assessing the client’s skin the nurse notices a rounded area of hair loss with redness, pustules, and scales that appear greenish-yellow when exposed to a black light (Wood’s lamp). The nurse should plan to implement treatment for which condition?

Accepted Answer

Answer reason: The described yellow-green appearance under black light supports a fungal etiology because certain organisms produce characteristic fluorescence patterns. A bacterial anaerobic process would more often present with foul-smelling, necrotic, deeper tissue infection rather than a scaly alopecic plaque. Contact dermatitis typically causes pruritic erythema and vesiculation in an exposure pattern and does not cause focal hair loss with fluorescent scaling.

Question 20

A 9-year-old child is admitted to the hospital with deep partial-thickness burns to 25% of his body. Which assessment finding would the nurse associate with a deep partial-thickness burn?

Accepted Answer

Answer reason: This depth is characterized by significant dermal tissue injury/necrosis while not destroying the full thickness of skin. Full-thickness burns are defined by necrosis through all skin layers, which makes that option too deep. Findings like only erythema and pain or minimal epidermal damage align more with superficial burns rather than deep partial-thickness injury.

Question 21

An infant is examined and found to have a petechial rash. The nurse documents a description of this rash as?

Accepted Answer

Answer reason: The key distinguishing features are the pinpoint size and lack of blanching with pressure, reflecting extravasated blood rather than vasodilation. Lesions larger than 1 cm are more consistent with ecchymoses, and “various sizes” bruising descriptions do not capture the defining small, pinpoint morphology. Accurate characterization matters because petechiae can signal thrombocytopenia or serious infection and warrant prompt evaluation.

Question 22

A 5-year-old male sustained third-degree burns to the right upper extremity after tipping over a frying pan. Which skin structures would the nurse include when explaining a third-degree burn to the child’s mother?

Accepted Answer

Answer reason: Because cutaneous nerve endings are destroyed, these burns may be painless in the center despite severe tissue damage. Option B describes a partial-thickness (second-degree) burn, which typically preserves deeper structures and is quite painful. Option D describes injury extending into muscle, tendon, or bone, which is more consistent with a fourth-degree burn rather than a third-degree burn.

Question 23

A woman walks into the health clinic and frantically tells the nurse she is worried she might have lice. The nurse performs an assessment and determines that the client has lice when she observes which of the following?

Accepted Answer

Answer reason: This direct visualization is a classic, specific finding supporting the diagnosis on assessment. Diffuse pruritic wheals are more consistent with urticaria or an allergic reaction rather than lice. Linear burrows in finger/toe webs point to scabies, and an embedded stinger indicates a hymenoptera sting reaction.

Question 24

The nurse is discussing the appearance of a rash associated with varicella-zoster virus on a child in the pediatric unit with a student nurse. Which explanation about the rash would be correct?

Accepted Answer

Answer reason: Varicella (chickenpox) classically presents with an intensely pruritic rash that begins on the trunk with rapid spread to the face/scalp and later the extremities, with lesions progressing from macules to papules to vesicles (“dew drop on a rose petal”). Lesions typically appear in crops, so different stages are present at the same time, which is a key distinguishing feature. Koplik spots and a cephalocaudal maculopapular rash describe measles, not varicella. Yellow ulcers with red halos on hands/feet is more consistent with hand-foot-and-mouth disease.

Question 25

Which of the following is not excreted through the integumentary system?

Accepted Answer

Answer reason: g., sodium chloride), urea, and trace amounts of substances such as alcohol. These are dissolved in sweat and reach the skin surface for removal. Blood is not a normal excretory product of skin; its presence on the skin implies bleeding from damaged vessels, not physiologic excretion. Therefore the option that is not excreted through the integumentary system is the one that would indicate injury rather than a glandular waste pathway.

Question 26

During the physical exam of a 59 year old woman, she expresses concerns that she is seeing more lesions on her skin. The nurse practitioner assesses multiple scattered red 3 mm papules on the chest. They are non-tender. Which of the following is most likely?

Accepted Answer

Answer reason: The described lesions are scattered, red, ~3 mm, and non-tender, which matches typical cherry angiomas. Actinic keratoses are rough, scaly premalignant plaques on sun-exposed areas rather than discrete red papules. Seborrheic keratoses are waxy “stuck-on” brown/tan verrucous lesions, and solar lentigines are flat hyperpigmented macules, not papules.

Question 27

Intradermal injection is given into which layer?

Accepted Answer

Answer reason: g., wheal/bleb) used in tests like PPD and allergy testing. The dermis is superficial to subcutaneous fat and deeper than the epidermis, so proper technique targets this middle skin layer. Injecting into muscle or a vein would produce systemic delivery and is inconsistent with intradermal test purposes. Injecting into the fat layer would be subcutaneous, which does not reliably create the characteristic intradermal wheal needed for interpretation.

Question 28

The nurse receives shift report on a client who has a history of psoriasis. Which skin findings does the nurse expect to find when assessing a client with psoriasis?

Accepted Answer

Answer reason: Lesions classically occur on extensor surfaces such as the elbows and knees and may be pruritic. The description of rough red lesions limited to sun-exposed areas is more consistent with actinic damage or photosensitive dermatoses rather than psoriasis. Depigmented patches suggest vitiligo, and a solitary irregular small lesion raises concern for a localized nevus or early skin cancer rather than the typical symmetric plaque pattern.

Question 29

Which of the following integumentary changes is unlikely to occur in an older adult?

Accepted Answer

Answer reason: Sweat gland function also declines, so reduced sweating is a common age-related change and contributes to impaired thermoregulation. Older adults may appear paler due to reduced dermal vascularity and thinning of the epidermis, making underlying structures more visible. Sun-exposure–related hyperpigmented macules (senile lentigines) are also common with age, so their presence is expected rather than unlikely.

Question 30

White patches on skin are called —?

Accepted Answer

Answer reason: The term used for this finding is leukoderma (often used interchangeably with vitiligo in common exam usage). Psoriasis and eczema primarily cause inflammatory, scaly or erythematous lesions rather than true loss of pigment. Rosacea is characterized by facial flushing and papules/pustules, not discrete white patches.

Question 31

Which gland produces sweat?

Accepted Answer

Answer reason: These glands secrete fluid onto the skin surface through ducts, helping dissipate heat via evaporation and contributing to minor excretion of electrolytes. Sebaceous glands instead produce sebum (oil) to lubricate skin and hair, not sweat. Thyroid and adrenal glands are endocrine organs with systemic hormonal functions and do not directly secrete sweat onto the skin surface.

Question 32

Which pigment gives skin its color ?

Accepted Answer

Answer reason: Increased melanin content and larger/more numerous melanosomes darken skin and provide photoprotection by absorbing UV radiation. Hemoglobin mainly contributes to pink/red tones through dermal blood flow, and carotene can add a yellow-orange hue, but neither is the main determinant of baseline skin pigmentation. Bilirubin causes yellow discoloration in jaundice and is pathologic rather than a normal pigment defining skin color.

Question 33

Nurse Jeff is performing a skin assessment on a client with a facial lesion. It appears as a well-defined, red, scaling, thickened bump. This type of skin lesion refers to?

Accepted Answer

Answer reason: This description matches the classic appearance of squamous cell carcinoma, which often presents as a red, scaly, crusted, indurated lesion that can become nodular. Basal cell carcinoma more typically appears as a pearly/waxy papule with telangiectasias and may ulcerate (“rolled border”), rather than a primarily scaly thickened bump. Melanoma is suggested by pigmented lesions with ABCDE changes, and Kaposi sarcoma classically presents as violaceous macules/plaques/nodules, often in immunocompromised patients.

Question 34

The largest organ of the body is —?

Accepted Answer

Answer reason: It covers the entire external body surface and functions as a barrier, thermoregulator, sensory organ, and part of immune defense. While the liver is the largest internal organ and the kidney and heart are vital organs, none exceed skin in total surface area and integrated tissue mass. Therefore, the option identifying skin best matches the definition used in anatomy and physiology.

Question 35

Which pigment gives skin its color?

Accepted Answer

Answer reason: This pigment increases with UV exposure and provides photoprotection by absorbing ultraviolet radiation. Carotene can contribute a yellow-orange hue and hemoglobin contributes a pink-red tone through dermal blood flow, but neither is the main determinant of baseline skin pigmentation. Bilirubin is associated with jaundice and abnormal yellowing rather than normal skin color.

Question 36

Which protein provides strength and water resistance to the skin?

Accepted Answer

Answer reason: Keratin intermediate filaments strengthen cells and, along with the cornified envelope and associated lipids, help limit transepidermal water loss. Collagen mainly provides tensile strength in the dermis rather than water resistance at the surface. Elastin and fibrillin contribute to elastic recoil and microfibril structure, not the primary water-resistant barrier function.

Question 37

The nurse understands that the calciferol hormone is produced by which of the following body systems?

Accepted Answer

Answer reason: This makes the integumentary system the primary site of initial calciferol production. The kidneys then activate vitamin D to calcitriol, but that is a conversion step rather than initial production. The other listed systems are not responsible for generating calciferol from skin precursors.

Question 38

What is the largest organ of the human body?

Accepted Answer

Answer reason: The integumentary system covers the entire body surface and, in adults, comprises the greatest organ by area and commonly by weight. It functions as a protective barrier, supports thermoregulation, sensation, and vitamin D synthesis, reflecting organ-level complexity. Other listed organs are large and vital but do not approach the body-wide surface coverage and aggregate size of the integument.
