Question 1 of 5
The protein in the epidermis that prevents dehydration is:
Correct Answer: A
Rationale: The correct answer is A: keratin. Keratin is a structural protein found in the epidermis that forms a protective barrier to prevent dehydration. It helps to waterproof the skin and protect it from environmental factors. Melanin (B) is responsible for skin pigmentation, collagen (C) provides structural support, and elastin (D) helps skin elasticity. However, these proteins do not specifically prevent dehydration in the epidermis.
Question 2 of 5
Which of the following substances is most likely to cause skin irritation in an individual with irritant-type contact dermatitis?
Correct Answer: B
Rationale: The correct answer is B, harsh soaps. Harsh soaps contain chemicals that can strip the skin of its natural oils, leading to skin irritation in individuals with irritant-type contact dermatitis. Warm water (choice A) is not a common irritant unless it is too hot. Nonlatex gloves (choice C) are typically used to protect the skin and are less likely to cause irritation. Vegetable oils (choice D) are generally considered safe and may even provide moisture to the skin.
Question 3 of 5
A client is admitted with extensive bone and soft-tissue injuries to the leg. Sterile dressings are applied. Two days later, when removing the dressings, the nurse finds that one of the dressings has adhered to tissue in several places. Which action would be taken by the nurse to loosen the dressings?
Correct Answer: D
Rationale: The correct answer is D: Moisten the dressing with sterile saline. This is the most appropriate action because moistening the dressing with sterile saline helps to loosen it without causing further damage or trauma to the tissue. The moisture helps to break the adherence between the dressing and the tissue, making it easier and less painful to remove. A: Applying diluted hydrogen peroxide is not recommended as it can be irritating to the tissue and may cause further damage. B: Pulling with gentle but steady traction can cause trauma and pain to the tissue that the dressing is adhered to. C: Soaking the area in a solution of Betadine is not necessary and may not effectively loosen the dressing compared to using sterile saline.
Question 4 of 5
Which response would the nurse give to a client who asks, “What is causing my acne?â€
Correct Answer: D
Rationale: The correct answer is D because increased androgenic hormones stimulate sebaceous glands, leading to excess oil production and acne. This is supported by scientific evidence. Choice A (eating chocolate) and B (eating fatty foods) lack direct correlation to acne development. Choice C (poor hygiene) can contribute to acne but is not the primary cause. Therefore, D is the most logical response based on the pathophysiology of acne.
Question 5 of 5
A nurse is caring for an older adult admitted to the hospital for dehydration. While the nurse is providing discharge teaching, the client says, “ What should I do about my dry skin? It is so itchy.†Which response by the nurse is appropriate?
Correct Answer: B
Rationale: The correct answer is B: Use a moisturizer on the skin daily to help reduce itching. Moisturizers help hydrate the skin, reduce dryness, and alleviate itching. It is important for older adults with dry skin to maintain skin hydration to prevent further complications. Choice A is incorrect as wearing warm clothes does not directly address the dryness and itching of the skin. Choice C is incorrect as hot baths can actually worsen dry skin by stripping away natural oils. Choice D is incorrect as exposing the skin to the air may lead to further dryness and discomfort.
