What is the primary reason older adults are at higher risk for adverse reactions to anesthesia?

Correct Answer: D

Rationale: The correct answer is D: Age-related changes in liver function. As people age, there are changes in liver metabolism and blood flow, affecting the processing of anesthetic agents. Liver function declines with age, leading to slower drug metabolism and clearance, increasing the risk of adverse reactions. Decreased muscle mass (A) may affect drug distribution but not metabolism. Decreased renal function (B) can impact drug excretion but is not the primary reason for adverse reactions. Increased body fat (C) can alter drug distribution but is not the main factor in anesthesia reactions for older adults.

Correct Answer: B

Rationale: The correct answer is B. Fewer than 50% of older adults utilize available preventive services. This is important for a community health initiative as it highlights a gap in healthcare utilization among seniors. By recognizing this statistic, the nurse can tailor the initiative to target the barriers preventing seniors from accessing preventive services. Rationale: 1. Option A is incorrect because stating that approximately 60% of older adults actively participate in preventive health services is misleading. The actual utilization rate is lower. 2. Option C is incorrect as it focuses on preference for alternative medicine rather than actual utilization of preventive health services. 3. Option D is incorrect as it states preventive health services are equally utilized by older and younger adults, which is not supported by data regarding senior healthcare utilization.

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: A

Rationale: The correct answer is A because social aging refers to changes in a person's roles and relationships as they age. Retiring from a job is a significant social change that typically accompanies aging. This indicates a shift in the man's social status and activities, which aligns with the concept of social aging. B, C, and D are incorrect because taking multiple medications, using a walker, and celebrating a 65th birthday are not direct indicators of social aging. While these factors may be related to aging, they do not specifically address the social aspects of aging, which is the focus of the question.

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.

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: 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: Being adequately nourished. Malnutrition weakens the immune system, making individuals more susceptible to infections like tuberculosis. Diabetes (A), living in crowded institutions (B), and immunosuppression (D) all lower immunity, increasing the risk of developing TB. In summary, adequate nutrition is not a risk factor for TB in the elderly, while diabetes, institutional living, and immunosuppression are.

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.
