Correct Answer: C

Rationale: The correct answer is C, regular exercise to improve strength and balance. This is the most effective strategy for preventing falls in older adults because it helps increase muscle strength, improve balance, and enhance coordination, reducing the risk of falls. Exercise also improves overall mobility and flexibility, which are essential for preventing falls. Installing bed alarms (A) may alert staff after a fall but does not prevent falls. Using medications to sedate the patient (B) can increase the risk of falls due to dizziness and impaired balance. Restricting movement (D) can lead to muscle weakness and loss of balance, increasing the risk of falls.

Correct Answer: C

Rationale: The correct answer is C because a decrease in alveolar elasticity is not a physical change that directly leads to an increasing incidence of hypertension in the older adult. Arterial stiffening and loss of elasticity (choice A) can lead to increased blood pressure. Changes in renal regulation of sodium and water (choice B) can impact fluid balance and blood pressure. Increasing body weight (choice D) can contribute to hypertension through increased strain on the cardiovascular system. Therefore, a decrease in alveolar elasticity is not directly related to hypertension in the same way as the other choices.

Correct Answer: B

Rationale: The correct answer is B because Mezey and Fulmer (2002) justify gerontological nursing research by emphasizing that it positively influences outcomes from nursing care. This is supported by evidence showing how research in gerontological nursing can lead to improved quality of care for older adults. Other choices are incorrect: A is not directly supported by the justification provided by Mezey and Fulmer (2002), C is too specific and not the main focus of their justification, and D is not mentioned in the justification and does not address the impact of research on nursing care outcomes.

Correct Answer: C

Rationale: The correct answer is C, regular exercise to improve strength and balance. This is the most effective strategy for preventing falls in older adults because it helps increase muscle strength, improve balance, and enhance coordination, reducing the risk of falls. Exercise also improves overall mobility and flexibility, which are essential for preventing falls. Installing bed alarms (A) may alert staff after a fall but does not prevent falls. Using medications to sedate the patient (B) can increase the risk of falls due to dizziness and impaired balance. Restricting movement (D) can lead to muscle weakness and loss of balance, increasing the risk of falls.

Correct Answer: C

Rationale: The correct answer is C: Regular review and adjustment of medications by healthcare providers. This approach is the best because it involves healthcare professionals regularly assessing the appropriateness of each medication, adjusting dosages, and eliminating unnecessary drugs to minimize potential adverse effects and drug interactions in older adults. This proactive management strategy ensures that the patient's medication regimen is optimized for their specific health needs, reducing the risks associated with polypharmacy. Choice A (Regular use of over-the-counter medications) is incorrect as it does not address the issue of polypharmacy and may actually contribute to it. Choice B (Reducing the number of medications based on patient preferences) is not the best approach as patient preferences alone may not always align with the most effective and safe medication regimen. Choice D (Relying solely on herbal supplements) is also incorrect as herbal supplements can interact with prescribed medications, leading to potential complications.
