How does aging affect the immune response in older adults, making them more susceptible to infections?

Correct Answer: B

Rationale: Correct Answer: B Rationale: The thymus gland is responsible for producing T-cells, crucial for immune responses. As individuals age, the thymus gland shrinks and becomes less efficient, reducing the production of new T-cells. This decline in T-cell production weakens the immune response in older adults, making them more susceptible to infections. Therefore, choice B is correct. Summary of Incorrect Choices: A: Aging does not increase the production of white blood cells. In fact, the immune system may weaken with age due to a decline in key immune cells. C: Aging does not improve the body's ability to recognize and fight off pathogens. Instead, it often leads to a decline in immune function. D: While some inflammatory responses may increase with age, excessive inflammation can actually be harmful and contribute to age-related diseases, rather than providing protection.

Correct Answer: B

Rationale: Rationale for Correct Answer B: "Channeling Your Inner Strength Toward Wellness" 1. Focuses on a positive approach to aging by emphasizing inner strength and wellness. 2.

Summary of Incorrect Choices: A: "The Many Chronic Illnesses of Aging" - Focuses on negative aspects and does not promote a proactive approach to health. C: "Maximizing Function As You Age" - While important, it may not fully capture the holistic nature of health and wellness. D: "Conserving Your Strength As You Age" - Does not emphasize active engagement in promoting wellness and may promote a passive approach.

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: 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: 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: A

Rationale: The correct answer is A: Primarily in the last 30 years. This is because advancements in research methodologies, technology, and increased awareness of aging population's health needs have led to a significant increase in research rigor and scope in the past few decades. Choice B is too broad and vague. Choice C is incorrect as research on older adults' health outcomes predates the establishment of Medicare. Choice D is too limited in scope, as research on older adults' health outcomes has been ongoing for more than just the last decade.

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: B

Rationale: The correct answer is B: Conduct interviews for specific interests. This intervention allows the nurse to tailor activities to the individual preferences of the older women, promoting engagement and a sense of autonomy. By conducting interviews, the nurse can identify each person's unique interests and preferences, ensuring that the activities planned are meaningful and enjoyable for them. This personalized approach enhances the overall well-being of the residents. Choices A, C, and D are incorrect because they do not focus on individual interests and preferences. While baking cookies, arranging pet visits, and attending library events can be enjoyable activities for some individuals, they may not be suitable or engaging for all residents in the specified age group and setting. These options lack the personalization and customization that conducting interviews for specific interests provides, making them less effective in meeting the diverse needs and preferences of the older women in the assisted-living facility.
