Correct Answer: A

Rationale: The correct answer is A: Hypertension. Hypertension, or high blood pressure, is the most common chronic condition affecting older adults in the U.S. This is because aging increases the risk of developing hypertension due to changes in blood vessels and the heart. Hypertension can lead to serious health complications such as heart disease and stroke. Summary: B: Osteoporosis primarily affects bone density and is more common in older women. C: Alzheimer's disease is a type of dementia that affects memory and cognitive function, but it is not as prevalent as hypertension among older adults. D: Diabetes is a chronic condition characterized by high blood sugar levels and while it is common, hypertension is more prevalent in older adults in the U.S.

Correct Answer: C

Rationale: The correct answer is C: Free radical theory. This theory states that aging is caused by the accumulation of damage from free radicals in the body, which can be countered by antioxidants found in fruits and vegetables. Thus, the nurse considering the importance of a diet high in fruits and vegetables aligns with the free radical theory. Incorrect choices: A: Oxidative stress theory focuses on the imbalance between free radicals and antioxidants, not specifically on fruits and vegetables. B: Immunological theory relates to the immune system's role in aging, not directly linked to diet. D: Telomere theory concerns the role of telomeres in aging, not directly related to the benefits of fruits and vegetables.

Correct Answer: B

Rationale: The correct answer is B because health disparities refer to variations in health outcomes between different groups, often linked to social, economic, or environmental factors. This definition accurately captures the essence of health disparities by emphasizing the differences in health outcomes among various populations. Choice A is incorrect because it describes cultural elimination rather than health disparities. Choice C is incorrect as it focuses on statistical comparison rather than the health outcomes themselves. Choice D is incorrect as it discusses differing values and perspectives, which are not directly related to health disparities. In summary, choice B is the correct answer as it aligns with the definition and concept of health disparities.

Correct Answer: B

Rationale: The correct answer is B: administer the lowest dose of 2 mg. In older adults, especially the elderly, it is essential to start with the lowest effective dose of medication to minimize the risk of adverse effects. This approach follows the principle of "start low and go slow" when administering medications to older adults due to age-related changes in drug metabolism and increased sensitivity to medications. Administering the lowest effective dose helps to reduce the risk of potential complications such as respiratory depression, sedation, and falls. Choice A (administer the highest dose of 6 mg) is incorrect because starting with the highest dose can increase the risk of adverse effects in older adults. Choice C (avoid the narcotic because of the risk of addiction) is incorrect as it is important to manage pain effectively in post-operative patients, and opioids can be safely used under proper supervision. Choice D (administer the dose only when the client asks for the medication 2 times) is incorrect as pain management should be

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.
