Question 1 of 5
Nails are useful for:
Correct Answer: D
Rationale: The correct answer is D because nails are indeed useful for scratching, protecting the ends of fingers and toes, and picking up small objects. Nails have various functions due to their structure and strength. They can be used to scratch an itch, provide protection to the fingertips and toes, and aid in picking up small items. Therefore, D is the correct choice as it encompasses all the valid uses of nails. Choices A, B, and C are incorrect individually as they only represent specific functions of nails, whereas option D covers all the mentioned uses.
Question 2 of 5
Which statement is NOT true of the proteins of the skin?
Correct Answer: C
Rationale: The correct answer is C because elastin is not present in the epidermis but in the dermis. Elastin gives skin its elasticity, not in the epidermis but in the dermis. The epidermis mainly consists of keratinocytes. Therefore, the statement that Elastin in the epidermis loses its elasticity with age is incorrect. Choices A, B, and D are all true statements about the proteins of the skin. Melanin production being genetic, keratin in nails being stronger than in the stratum corneum, and collagen fibers in the dermis providing strength are all accurate characteristics of skin proteins.
Question 3 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 4 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 5 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.
