While assessing several clients in a long-term health care facility, which client is at the highest risk for developing decubitus ulcers?

Correct Answer: A

Rationale: The correct answer is A: A 79-year-old malnourished client on bed rest. This client is at the highest risk for developing decubitus ulcers due to being malnourished and on bed rest, leading to decreased mobility and poor nutrition. This combination puts the client at significant risk for skin breakdown and pressure ulcers. Choice B is incorrect because although obesity is a risk factor for developing pressure ulcers, immobility and poor nutrition are higher risk factors. Choice C is incorrect as incontinence can contribute to skin breakdown but is not as high a risk factor as immobility and poor nutrition. Choice D is incorrect as an ambulatory client, even if diabetic, has better mobility than a bedridden client and is at lower risk for developing decubitus ulcers.

Correct Answer: C

Rationale: In chronic renal failure, proteins should be limited in the diet. When the kidneys are not functioning well, the buildup of protein byproducts can put additional stress on them. Limiting protein intake can help reduce the burden on the kidneys. Carbohydrates and fats do not need to be restricted in the same way as proteins. Vitamins are essential nutrients that should not be limited in the diet unless specified by a healthcare provider for a specific reason.

Correct Answer: C

Rationale: The correct answer is C. Using cold packs to relieve joint pain is appropriate for clients with rheumatoid arthritis as cold therapy is more effective at reducing inflammation and pain in these conditions. Heat applications may exacerbate the symptoms by increasing swelling. Taking warm showers before activity may provide comfort but does not directly address joint pain or prevent injury. While anti-inflammatory medications are commonly prescribed, they are not directly related to preventing injury in clients with rheumatoid arthritis.

Correct Answer: A

Rationale: The most appropriate intervention for the nurse to suggest to a 30-year-old male client experiencing difficulty sleeping due to anxiety about his upcoming surgery is to recommend taking a mild sedative before bed. A mild sedative can help manage anxiety and improve sleep in such situations. Encouraging physical activity before bedtime, advising to listen to calming music, or recommending reading a book may not directly address the client's anxiety and may not be as effective in promoting sleep in this scenario.

Correct Answer: C

Rationale: The correct answer is C: 'NPO reduces the risk of aspiration during surgery.' When a client is NPO (nothing by mouth) before surgery, it is to prevent aspiration, which can lead to serious complications such as pneumonia. Choice A is incorrect because being NPO is more about preventing aspiration than nausea. Choice B is a general statement without specifying the reason for being NPO. Choice D is partially correct but does not emphasize the crucial aspect of preventing aspiration, which is the primary reason for fasting before surgery.
