Correct Answer: B

Rationale: The correct answer is B: Prolonged medication half-life. As clients age, their metabolism tends to slow down, leading to a prolonged half-life of medications in the body. This extended presence of drugs can increase the risk for adverse effects as the substances accumulate. Choice A, rapid gastric emptying, is not an age-related change and actually decreases the time medications spend in the stomach, potentially reducing their effectiveness. Choice C, increased medication elimination, is not an age-related change either; in fact, aging can lead to decreased renal function, affecting drug elimination. Choice D, decreased medication sensitivity, is not an age-related change that directly increases the risk for adverse effects; rather, it may lead to requiring higher doses for effectiveness but does not inherently increase the risk of adverse effects.

Correct Answer: A

Rationale: The correct answer is to verify the client's blood type with the provider's prescription. This is crucial to prevent an adverse transfusion reaction due to incompatibility. Ensuring the blood type matches before starting the transfusion is a standard safety practice. Option B, ensuring client consent, is important but not directly related to preventing a transfusion reaction. Option C, administering a diuretic, is unnecessary and can be harmful in this context. Option D, checking the client's temperature, is important for general assessment but not specifically focused on preventing a transfusion reaction.

Correct Answer: A

Rationale: In this scenario, the nurse should arrange for an ethics committee meeting to address the family's concerns while ensuring the client's wishes are respected. Choosing option A allows for a formal discussion involving healthcare professionals, family members, and possibly a legal expert to navigate the situation ethically and legally. Supporting the family's decision to initiate life-sustaining measures (option B) would disregard the client's advance directives and autonomy. Completing an incident report (option C) is not appropriate in this situation as it does not address the conflict of interest between the family's desires and the client's wishes. Encouraging the family to contact an attorney (option D) may escalate the situation unnecessarily before exploring more ethical and collaborative approaches.

Correct Answer: C

Rationale: The correct answer is C: Clear lung sounds. Clear lung sounds indicate a therapeutic effect of furosemide, as the medication helps reduce fluid overload in heart failure. Choice A, increased shortness of breath, is incorrect as furosemide is used to relieve symptoms like shortness of breath. Choice B, weight gain of 2.3 kg (5 lb), is incorrect as furosemide is a diuretic that helps reduce fluid retention leading to weight loss. Choice D, bounding pulse, is incorrect as furosemide does not directly impact the pulse rate.

Correct Answer: B

Rationale: The correct statement the nurse should include in the teaching for a client with a new prescription for furosemide is that the client should take the medication with food to prevent gastrointestinal upset. Furosemide is a loop diuretic that can cause gastrointestinal upset, so taking it with food can help reduce this side effect and improve medication tolerance. Choices A, C, and D are incorrect because furosemide does not increase potassium levels, decrease blood glucose levels, or require an increase in the intake of potassium-rich foods. Therefore, the most important teaching point for the client is to take furosemide with food.
