Correct Answer: B

Rationale: The correct answer is to apply a moisture-retentive dressing. This promotes a moist wound environment, which is crucial for wound healing in clients with diabetes. Encouraging a high-protein diet may support overall health but is not directly related to wound healing. Daily wound irrigation can disrupt the wound healing process by removing necessary growth factors and cells. Applying an ice pack to the wound is contraindicated as it can impair circulation and delay wound healing.

Correct Answer: D

Rationale: The correct answer is D: Lowered immune function. Older adults often experience a decline in immune function as they age, making them more vulnerable to infections. This weakened immune system can result in increased susceptibility to various pathogens. Choice A, 'Improved nutritional status,' is incorrect because good nutrition can actually help support the immune system. Choice B, 'Increased mobility,' is not directly related to an increased risk of infections. Choice C, 'Chronic conditions,' while they can contribute to a weakened immune system, do not directly address the primary risk factor for infections in older adults.

Correct Answer: A

Rationale: Encouraging early ambulation is crucial in reducing the risk of postoperative complications, such as blood clots and pneumonia. Early mobilization helps prevent complications like deep vein thrombosis and pneumonia by promoting circulation and preventing respiratory complications. Providing intravenous antibiotics (Choice B) is important for preventing infections but is not the priority immediately post-surgery. Applying anti-embolism stockings (Choice C) is beneficial in preventing venous thromboembolism but does not address the immediate need for mobility. Placing a Foley catheter (Choice D) may be necessary during surgery but is not a priority intervention to reduce postoperative complications related to immobility.

Correct Answer: B

Rationale: The correct answer is to increase fluid intake to 2 liters per day. Adequate fluid intake helps manage hypertension and prevent fluid retention. Limiting sodium intake, avoiding potassium-rich foods, and abstaining from alcohol are important aspects of managing hypertension; however, in this scenario, emphasizing the increase in fluid intake is crucial for the client's understanding and compliance.

Correct Answer: C

Rationale: The correct answer is C: Orange slices. For a client on a mechanical soft diet, foods that are difficult to chew and swallow should be avoided. Orange slices have membranes that can be challenging to consume for individuals with swallowing difficulties. Steamed carrots (Choice A) and mashed potatoes (Choice B) are typically suitable for a mechanical soft diet as they can be easily mashed or cut into smaller pieces. Soft-cooked eggs (Choice D) are also appropriate for this diet as they are soft and easy to chew.
