Correct Answer: D

Rationale: The correct answer is D: “Your heart is not an efficient pump.” This response is the best choice as it accurately describes heart failure, which is a condition where the heart is unable to pump blood effectively. This leads to symptoms such as fatigue, shortness of breath, and fluid retention. Explanation: 1. Choice A is incorrect because heart failure does not mean the heart stops; it means the heart is not functioning properly. 2. Choice B is incorrect because heart failure does not necessarily mean there is dead muscle tissue in the heart. 3. Choice C is incorrect because heart failure is not about pumping too much blood; it is about the heart's inability to pump blood efficiently, leading to circulation problems and other symptoms.

Correct Answer: B

Rationale: The correct answer is B: Disturbed body image. The client expressing concern about the external fixation device making his leg look ugly indicates a disturbance in how he perceives his body image. This can lead to feelings of low self-esteem and impact his overall psychological well-being. Impaired physical mobility (A) is not the priority as the concern is not related to limitations in movement. Risk for infection (C) may be a potential risk with the device but is not directly related to the client's current concern. Risk for social isolation (D) is not directly indicated by the client's statement about the appearance of the leg. Therefore, the most appropriate nursing diagnosis is Disturbed body image (B) based on the client's expressed concern.

Correct Answer: B

Rationale: The correct answer is B because client-centered care emphasizes involving clients in decision-making. During evaluation, assessing if the care plan aligns with the client's preferences and goals ensures personalized and effective care. This approach enhances client satisfaction, engagement, and outcomes. Incorrect choices: A: Not considering the client's input goes against client-centered care principles. C: Prioritizing institutional policies over client feedback neglects the client's individual needs. D: Focusing solely on measurable clinical outcomes may not capture the holistic view of the client's well-being.

Correct Answer: B

Rationale: The correct answer is B: Aldosterone. Aldosterone is a hormone produced by the adrenal glands that helps regulate sodium and water balance in the body. It acts on the kidneys to increase reabsorption of sodium, leading to water retention and increased blood volume. This helps maintain blood pressure and electrolyte balance. A: Antidiuretic hormone (ADH) mainly acts on the kidneys to increase water reabsorption, not sodium retention. C: Thyroid hormone does not directly influence sodium retention. D: Insulin regulates blood sugar levels by promoting glucose uptake, it does not have a direct role in sodium retention.

Correct Answer: D

Rationale: The correct answer is D: high calorie high protein. In COPD exacerbation, the body requires extra calories and protein for energy and muscle strength. High-calorie foods help combat weight loss and fatigue. High-protein foods aid in muscle repair and maintenance. Low-fat low-cholesterol (A) is not ideal as healthy fats are needed. Low-sodium (B) is not necessary unless there is concurrent heart failure. Bland soft diet (C) is not suitable as it does not provide enough calories and protein needed for COPD exacerbation.
