Which of the following is the most important factor in managing malnutrition in older adults?

Correct Answer: B

Rationale: The correct answer is B: Increasing protein intake. Protein is crucial for maintaining muscle mass and strength in older adults, aiding in the prevention and management of malnutrition. Protein also supports immune function and wound healing. Reducing calorie intake (A) can exacerbate malnutrition, as older adults need adequate nutrition. Avoiding all fats (C) is not recommended as healthy fats are essential for brain health and nutrient absorption. Limiting hydration (D) can lead to dehydration and worsen malnutrition. In summary, increasing protein intake is the most important factor in managing malnutrition in older adults due to its vital role in maintaining overall health and preventing muscle loss.

Correct Answer: C

Rationale: The correct answer is C because regularly reviewing and adjusting medications can help minimize adverse effects of polypharmacy in older adults. This approach ensures that the medications are appropriate, necessary, and not causing harm. A: Encouraging herbal supplements is not a recommended approach as they can interact with prescription medications. B: Prioritizing over-the-counter medications may not address the complexities of polypharmacy and can still contribute to drug interactions. D: Limiting patient discussions about medications can lead to misunderstandings and non-adherence.

Correct Answer: B

Rationale: Step 1: Conducting regular reviews allows nurses to assess the necessity and appropriateness of each medication, addressing potential drug interactions, duplications, and side effects in elderly patients. Step 2: This proactive approach helps prevent polypharmacy-related complications and ensures optimal medication management. Step 3: Ensuring medications are taken exactly as directed (A) may not address the root cause of polypharmacy. Recommending over-the-counter medications (C) without proper evaluation can worsen the issue. Administering medications only during hospital stays (D) is not a comprehensive solution outside of the hospital setting.

Correct Answer: A

Rationale: The correct answer is A because as individuals age, there is a decrease in renal function leading to reduced renal clearance of drugs. This results in a longer drug half-life and potentially increased drug accumulation in the body. Choice B is incorrect as aging often leads to a decrease in hepatic metabolism, not faster metabolism. Choice C is incorrect because aging can actually lead to reduced gastrointestinal absorption due to changes in the gastrointestinal tract. Choice D is incorrect as aging can result in decreased circulation, which may affect drug distribution negatively.

Correct Answer: C

Rationale: The correct answer is C: Monitoring for electrolyte imbalances and adjusting medications accordingly. In advanced CKD, electrolyte imbalances can worsen kidney function and lead to complications. Monitoring electrolytes like potassium and adjusting medications such as diuretics is crucial. A: Initiating early dialysis is not always necessary and should be based on individual patient factors. B: Avoiding all medications is not feasible as some medications are essential and can be adjusted based on kidney function. D: Limiting fluid intake to less than 500 mL per day is too restrictive and can lead to dehydration.
