Integumentary System Exam Questions Questions
Question 1 of 5
In applying topical steroids to psoriatic lesions clients are taught to
Correct Answer: B
Rationale: The correct answer is B: apply plastic wrap occlusive dressings. This method helps enhance the penetration of the topical steroid into the skin, increasing its effectiveness. Occlusive dressings create a barrier that traps moisture and heat, promoting better absorption. Leaving the lesion open (A) would not optimize the medication's effects. Loose gauze dressings (C) may not provide sufficient occlusion. Thoroughly washing and reapplying lotion (D) four times daily would not ensure consistent steroid application or occlusion.
Question 2 of 5
Some cells in the subcutaneous tissue produce histamine, which contributes to the process of:
Correct Answer: D
Rationale: The correct answer is D: inflammation. Histamine is released by cells in response to injury or allergens, leading to vasodilation and increased permeability of blood vessels, causing redness and swelling - classic signs of inflammation. Inflammation is a protective response that helps the body to eliminate harmful stimuli and initiate the healing process. Choices A, B, and C are incorrect because histamine does not play a role in infection, mitosis, or energy storage.
Question 3 of 5
Which statement is NOT true of the dermis?
Correct Answer: A
Rationale: The correct answer is A because the papillary layer of the dermis actually anchors the epidermis to the dermis, not the dermis to the subcutaneous tissue. The papillary layer contains blood vessels, nerves, and touch receptors. Choice B is correct because hair follicles are indeed found in the dermis, providing nourishment to hair. Choice C is incorrect because the secretory portions of sebaceous glands are actually located in the subcutaneous layer, not the dermis. Choice D is incorrect because many cutaneous receptors, such as Meissner's corpuscles and Pacinian corpuscles, are located in the dermis, responsible for sensations like touch and pressure.
Question 4 of 5
The healthcare provider has ordered Collagenase for a patient with a left leg necrotic ulcer. What does the nurse understands about the use of collagenase?
Correct Answer: C
Rationale: The correct answer is C because Collagenase speeds up the rate at which necrotic tissue is removed by breaking down collagen within the necrotic tissue. This enzyme helps to debride the wound and promote healing. Choice A is incorrect as collagenase does not absorb exudates. Choice B is incorrect because collagenase is not the body's own digestive enzymes. Choice D is incorrect because collagenase does not remove exudate through high moisture-vapor transmission rate.
Question 5 of 5
The nurse is caring for a 32-year-old with circumferential full-thickness burns to the right arm and trunk. Which nursing intervention has the highest priority in the plan of care?
Correct Answer: A
Rationale: The correct answer is A: Assess radial pulses several times a day. This is the highest priority because the patient has circumferential full-thickness burns, which can cause compartment syndrome and compromise circulation. Assessing radial pulses helps monitor blood flow to the affected areas. B is incorrect as it's not directly related to the patient's condition. C can potentially cause harm due to the risk of further damaging the burned skin. D is incorrect as removing blisters can increase the risk of infection and delay healing.
