Integumentary System CPT Questions and Answers Questions
Question 1 of 5
Which statement is NOT true of the epidermis?
Correct Answer: A
Rationale: The correct answer is A because mitosis actually takes place in the lowest layer of the epidermis called the stratum basale, not the stratum corneum. The stratum corneum is the outermost layer of the epidermis composed of dead skin cells. Mitosis is necessary for cell renewal, and it occurs in the stratum basale where new skin cells are constantly produced. Langerhans cells in the epidermis are responsible for picking up pathogens, making statement B true. Statement C is also true as the intact stratum corneum acts as a protective barrier against bacteria and chemicals. Lastly, statement D is true as the stratum germinativum (also known as the stratum basale) is indeed adjacent to the dermis, the layer of skin below the epidermis.
Question 2 of 5
If possible, a patient with Stevens–Johnson syndrome should receive treatment in a regional burn center.
Correct Answer: A
Rationale: The correct answer is A because Stevens-Johnson syndrome is a severe skin condition that can lead to extensive skin loss and mucosal damage, similar to burn injuries. Regional burn centers have the expertise and resources to manage such complex cases effectively, including specialized wound care, monitoring for complications, and multidisciplinary care. Therefore, transferring the patient to a burn center can improve outcomes and reduce the risk of complications. Other choices are incorrect because without the specialized care available at a burn center, the patient's condition may worsen, leading to increased morbidity and mortality.
Question 3 of 5
Which action by a family member of a client with a wound requiring sterile dressings would indicate the need for additional teaching?
Correct Answer: D
Rationale: The correct answer is D because using a back-and-forth motion while cleaning the wound introduces the risk of cross-contamination. Cleaning should be done in a gentle, single-direction motion to prevent spreading microorganisms. Placing the old dressing in a plastic bag (A) is appropriate for disposal. Changing the dressing without wearing a mask (B) is not necessary unless there are specific respiratory concerns. Donning nonsterile gloves before removing the old dressing (C) is incorrect, as sterile gloves should be worn to prevent contamination.
Question 4 of 5
Which condition would a nurse suspect in a client with pitting edema?
Correct Answer: B
Rationale: The correct answer is B: Kidney disease- may be associated with pitting edema. Pitting edema is when pressure on the skin causes an indentation that persists for some time. Kidney disease can lead to fluid retention, causing pitting edema due to impaired kidney function in regulating fluid balance. Shock (A) is characterized by decreased cardiac output, not typically associated with pitting edema. Hypothyroidism (C) can cause nonpitting edema due to accumulation of mucopolysaccharides in the dermis. Severe dehydration (D) leads to turgor loss but not typically pitting edema.
Question 5 of 5
Which recommendation would a nurse include to a client with psoriasis when providing health teaching concerning skin care at home?
Correct Answer: C
Rationale: The correct answer is C. Applying moisturizing lotion several times a day is recommended for clients with psoriasis to help maintain skin hydration and reduce itching and irritation. It helps to soothe and protect the skin barrier. Showering twice a day (choice A) can strip the skin of natural oils, exacerbating dryness. Soaking in hot water (choice B) can worsen inflammation and dry out the skin. Covering affected areas when in contact with others (choice D) may be necessary for infection control but does not address the primary skin care needs of psoriasis.
