Correct Answer: B

Rationale: A new or changed heart murmur is a common sign of valve involvement in infective endocarditis, indicating a complication such as valve damage or regurgitation. Dyspnea is more commonly associated with respiratory or cardiac conditions not directly related to infective endocarditis. A macular rash is not a typical symptom of infective endocarditis, suggesting other conditions like infectious diseases. Hemorrhage is not a direct complication of infective endocarditis but may occur due to factors such as anticoagulant therapy or underlying bleeding disorders.

Correct Answer: C

Rationale: Clients who have undergone significant visible body changes, like amputation, are at increased risk for body-image disturbances. Amputation can have a profound impact on self-image and body perception due to the visible structural alteration. While conditions like laparoscopic appendectomy, mastectomy, and cardiac catheterization may also affect body image, they are less likely to cause significant disturbances compared to visible changes like amputation.

Correct Answer: A

Rationale: Low sodium levels (hyponatremia) often present with various symptoms, including abdominal cramping. Abdominal cramping is a common manifestation of hyponatremia due to the altered electrolyte balance. Option B ('Elevated blood pressure') is incorrect because low sodium levels typically lead to decreased blood pressure, not elevated. Option C ('Decreased heart rate') is incorrect as low sodium levels are more likely to cause an irregular heart rate rather than a decreased heart rate. Option D ('Increased thirst') is incorrect because excessive thirst is more commonly associated with high sodium levels (hypernatremia) rather than low sodium levels.

Correct Answer: D

Rationale: To ensure the client's safety during a blood transfusion, it is crucial to verify the blood product with another nurse before administration. This step helps confirm the correct blood type and prevents transfusion reactions. While checking the client's identification and blood type (Choice A) is important, the ultimate responsibility lies with confirming the blood product before administration. Monitoring vital signs (Choice B) is necessary during a transfusion but does not directly address verifying the blood product. Administering blood through a peripheral IV line (Choice C) is a common practice but does not specifically ensure that the correct blood product is being administered, which is essential for the client's safety.

Correct Answer: A

Rationale: The best action by the nurse is to respect the patient's preference and autonomy. Defer the bath until evening to allow the patient to follow their usual hygiene routine. Passing on the information to the next shift ensures continuity of care. Choice B is incorrect because it disregards the patient's preference and autonomy. Choice C, while important, does not address the patient's immediate concern. Choice D is incorrect as it does not respect the patient's wishes and may lead to further resistance to bathing.
