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: C

Rationale: The correct answer is C: The patient's advanced directives and wishes. This is crucial in end-of-life care as it ensures that the patient's preferences and values are respected. By evaluating the advanced directives and wishes, the nurse can provide care that aligns with the patient's goals and desires. This promotes autonomy and dignity in the patient's end-of-life experience. Choice A (Patient's financial situation) is not as crucial as the patient's wishes in end-of-life care, as financial considerations should not dictate the quality of care provided. Choice B (The family’s expectations) is important, but the patient's wishes should take precedence as it is their care and preferences that should be the primary focus. Choice D (The patient's history of medication use) is relevant for overall care but not as crucial in end-of-life care as honoring the patient's wishes and directives.

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.

Correct Answer: B

Rationale: The correct answer is B because antibiotics are not standard therapy for congestive heart failure in the elderly. The rationale is that antibiotics are used to treat bacterial infections, not heart failure. A: ACE inhibitors are standard therapy as they help dilate blood vessels and reduce the workload on the heart. C: Diuretics help reduce fluid buildup in the body, which is beneficial for managing CHF symptoms. D: Beta blockers are used to reduce the heart's workload and help manage the stress response, making them standard therapy for CHF.

Correct Answer: B

Rationale: The correct answer is B. Decreased hearing in older individuals can lead to increased danger as they may not be able to hear important warning sounds like smoke or security alarms. This can compromise their safety and well-being. A is incorrect because decreased hearing may lead to increased stressful interactions due to difficulties in communication. C is incorrect because decreased hearing can actually increase danger when driving or walking in traffic as the individual may not be able to hear car horns or other traffic sounds, leading to potential accidents. D is incorrect because decreased hearing can contribute to an increased risk of falls due to decreased awareness of environmental sounds and hazards.
