Correct Answer: A

Rationale: Choice A is the correct answer because as individuals age, there is a normal decline in cardiac efficiency, leading to a slower return to baseline heart rate after exercise. This statement demonstrates an understanding of an expected change related to aging. Choice B is incorrect as vision typically declines with age due to changes in the eye's structure. Choice C is incorrect because aging usually leads to a decrease in skin elasticity. Choice D is incorrect as hearing tends to decline rather than become more acute with age.

Correct Answer: C

Rationale: Keeping a food diary is an essential practice when starting a weight loss plan as it helps in tracking calorie intake, identifying eating patterns, and making informed decisions about dietary changes. Planning meals with low carbohydrates and high protein (Choice A) can be beneficial for some individuals, but keeping a food diary is more foundational. Engaging in strenuous daily activity (Choice B) may not be sustainable for everyone and could lead to burnout or injuries. Participating in a group exercise class (Choice D) is beneficial for fitness but may not address dietary habits, which are crucial for weight loss.

Correct Answer: A

Rationale: Discharge planning for a client with an exacerbation of heart failure should begin during the admission process. Initiating discharge planning early ensures a smooth transition and continuity of care for the client. Option B, after the client is stabilized, is not ideal because planning should start early to address potential barriers to discharge. Option C, when the client expresses readiness to go home, may be too late as discharge planning is a proactive process. Option D, just before the expected discharge date, does not allow enough time for comprehensive planning and coordination of post-discharge care needs.

Correct Answer: C

Rationale: The correct position for a client immediately following a liver biopsy is right side-lying with a pillow under the costal margin. This position helps prevent bleeding by applying pressure to the biopsy site. Placing the client supine with the right arm raised above the head (Choice A) or supine with the head of the bed elevated (Choice B) are not ideal positions for post-liver biopsy care as they do not provide the necessary pressure to the biopsy site. Left side-lying with the head of the bed flat (Choice D) is also not recommended as it does not assist in preventing bleeding after a liver biopsy.

Correct Answer: A

Rationale: In the nursing process, the planning step involves determining priorities and goals based on the identified problems. Choice A is correct as it reflects the nurse's role in identifying the most important client problems to address, which aligns with the planning phase. Choices B, C, and D are incorrect. Choice B involves data collection, which is a part of the assessment phase, not planning. Choice C pertains to the implementation of care, which occurs after the planning phase. Choice D involves evaluation of a specific intervention, not planning.
