Rationale: The correct answer is 'Decreased hepatic metabolism.' The elderly population is at risk for more side effects, adverse drug reactions, and toxicity due to a decrease in hepatic metabolism. This is caused by changes in hepatic functioning in the elderly, including decreased hepatic blood flow and functioning. Choice A, 'Increased creatinine clearance,' is incorrect as aging typically results in decreased, not increased, creatinine clearance. Choice B, 'Impaired immune system,' is not directly related to the increased risk of adverse drug reactions in the elderly. Choice D, 'Increased bodily fat,' is not a primary factor contributing to the increased risk of medication-related issues in the elderly population.

Correct Answer: B

Rationale: The theory of aging that aligns with the need for strict infection control prevention measures is the Immunological Theory of Aging. This theory posits that aging leads to a decline in the body's immune defenses and a reduced ability of antibodies to protect against infections. The other theories do not directly address the impact of aging on the immune system. The Programmed Longevity Theory focuses on genetic changes affecting aging, the Endocrine Theory emphasizes hormonal changes, and the Rate of Living Theory relates longevity to the rate of oxygen metabolism.

Rationale: A key principle of patient teaching that ensures patient safety is the confirmation of understanding. To ensure patient safety, it is crucial to confirm that the patient comprehends the information provided. This confirmation can be achieved by having the patient repeat back the information or demonstrate understanding through return demonstration. Documenting the patient's understanding is essential to track the effectiveness of the teaching session and ensure that the patient is equipped with the necessary knowledge for their safety. Family members being present or having multiple staff members provide teaching may be beneficial in certain situations, but the primary focus should be on confirming the patient's understanding to enhance safety and promote effective learning.

Correct Answer: A

Rationale: For a manic client who is hyperactive and may engage in injurious activities, setting realistic limits to the client's behavior is crucial to ensure safety. A quiet environment with firm and consistent limits helps in managing the client's behavior effectively. While repeating verbal instructions can be helpful due to the client's distractibility, it is not the priority compared to setting limits for safety concerns. Allowing the client to express feelings is important, but it should be done through non-destructive methods. Assigning staff to be with the client at all times is not realistic or feasible in the clinical setting and does not address the core issue of managing the client's behavior and ensuring safety.
