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: 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: C

Rationale: The correct answer is C because it highlights a common issue in nursing education where gerontological nursing content is often underrepresented, with less than 25% of the curriculum dedicated to geriatric care. This is accurate as many nursing programs prioritize other areas over gerontology. A is incorrect as gerontological nursing integration has historically been lacking in nursing curricula. B is incorrect because undergraduate programs often lack extensive coverage of gerontological nursing compared to other specialties like psychiatric nursing. D is incorrect as accreditation does not guarantee specific proportions of gerontological nursing content in the curriculum. Thus, choice C is the most accurate statement regarding gerontological nursing education.

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: 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: 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: 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.
