Integumentary System Exam Questions Questions
Question 1 of 5
Hair, epidermis, and nails are all made up of:
Correct Answer: A
Rationale: The correct answer is A: keratin. Keratin is a fibrous structural protein that is the main component of hair, epidermis, and nails. It provides strength, durability, and protection to these structures. Vitamin D (choice B) is important for bone health and is not a component of hair, epidermis, or nails. Adipose tissue (choice C) is fat tissue and is not a component of these structures. Collagen (choice D) is a different type of protein found in connective tissues such as tendons and ligaments, not in hair, epidermis, or nails.
Question 2 of 5
The evening nurse reviews the nursing documentation in the male client's chart and notes that the day nurse has documented that the client has a stage II pressure ulcer in the sacral area. Which of the following would the nurse expect to note on assessment of the client's sacral area?
Correct Answer: A
Rationale: The correct answer is A: Partial-thickness skin loss of the dermis. This aligns with the definition of a stage II pressure ulcer, which involves partial-thickness skin loss involving the epidermis and/or dermis. This stage typically presents as a shallow open ulcer with a red-pink wound bed. Choice B (Full-thickness skin loss) is incorrect as it corresponds to a stage III pressure ulcer where there is full-thickness tissue loss. Choice C (Blistering without skin loss) is incorrect as it describes a stage II pressure injury, not a pressure ulcer. Choice D (Intact skin with redness) is incorrect as it signifies a stage I pressure ulcer, where there is non-blanchable erythema of intact skin. Therefore, the nurse would expect to see partial-thickness skin loss of the dermis in the sacral area of the client with a stage II pressure ulcer.
Question 3 of 5
Nurse Bea plans to administer dexamethasone cream to a client who has dermatitis over the anterior chest. How should the nurse apply this topical agent?
Correct Answer: A
Rationale: The correct answer is A: With a circular motion, to enhance absorption. Applying dexamethasone cream in a circular motion helps distribute the medication evenly and promotes better absorption into the skin. This method ensures that the active ingredients are spread uniformly over the affected area, maximizing the therapeutic effects. Incorrect choices: B: In a thick layer - Applying a thick layer may lead to excessive absorption or wastage of the medication. C: With a downward stroke - Applying in a downward stroke may not distribute the cream evenly and may not facilitate absorption. D: Using a cotton ball only - Using a cotton ball may not provide the necessary pressure to evenly distribute the cream on the skin.
Question 4 of 5
The nurse manager is planning the clinical assignments for the day. Which staff members can be assigned to care for a client with herpes zoster?
Correct Answer: A
Rationale: The correct answer is A because a nurse who never had German Measles is not at risk of contracting herpes zoster from the client. Herpes zoster is caused by the reactivation of the varicella-zoster virus, which causes chickenpox. If a person has never had chickenpox, they are at risk of getting it from a client with herpes zoster. Roseola and mumps are not related to herpes zoster, so choices C and D are incorrect.
Question 5 of 5
What important safety measure regarding the use of insect repellents does the nurse teach a parenting group?
Correct Answer: A
Rationale: Step-by-step rationale: 1. Applying repellents to clothing reduces skin exposure. 2. It minimizes direct contact with skin, preventing potential irritation. 3. It also decreases absorption risks. 4. This method is safer, especially for children with sensitive skin. Summary of incorrect choices: B: DEET is not the only effective repellent; there are safe alternatives. C: Oil of lemon eucalyptus is not recommended for babies due to potential skin sensitivity. D: Washing off after 2 hours may reduce efficacy; reapplication is necessary for continued protection.
