Question 1 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 2 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 3 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 4 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.
Question 5 of 5
The mediastinum is located in which of the following cavities contains?
Correct Answer: B
Rationale: The correct answer is B: Thoracic. The mediastinum is a central compartment in the thoracic cavity that houses vital structures such as the heart, major blood vessels, esophagus, trachea, and thymus gland. It is located between the lungs and extends from the sternum to the vertebral column. The other choices are incorrect because: A: Dorsal refers to the back, C: Abdominal refers to the abdomen, and D: Cranial refers to the head. These locations do not accurately describe the position of the mediastinum.
