Correct Answer: C

Rationale: The correct answer is C: Disturbed body image related to the incision scar. This nursing diagnosis is appropriate as the client's concern about wearing a scarf post-surgery indicates a potential disturbance in body image due to the visible scar. The nurse should address the client's emotional response and offer support to help cope with the change in appearance. A: Risk for impaired physical mobility due to surgery - This choice is not directly related to the client's worry about wearing a scarf and focuses more on physical limitations post-surgery. B: Ineffective denial related to poor coping mechanisms - This choice does not address the specific body image concern expressed by the client. D: Risk of injury related to surgical outcomes - This choice does not address the client's emotional response to the scar and focuses on physical safety risks instead.

Correct Answer: A

Rationale: Rationale for Correct Answer (A): The nurse's best response is to inform the pregnant woman that all pregnant women must have an HIV test. This is because HIV testing is a standard part of prenatal care to prevent mother-to-child transmission. It is crucial to detect HIV early to provide appropriate treatment and prevent transmission to the baby. Summary of Incorrect Choices: B: This response could lead to misinformation and potentially harm the patient and her baby. HIV testing is recommended for all pregnant women regardless of risk factors. C: While governmental guidelines may vary, it is essential for all pregnant women to undergo HIV testing to ensure the health of both the mother and the baby. D: While it is important to provide counseling and involve the patient in decision-making, in the case of HIV testing during pregnancy, it is a standard procedure that should be offered to all pregnant women to safeguard their health and that of their baby.

Rationale: The correct answer is B: Wash and inspect the feet daily. This is important for clients with diabetes mellitus to prevent complications like foot ulcers. Daily foot care helps detect any issues early. Choice A is incorrect as it is not recommended to use commercial preparations without medical advice.

Choice D is incorrect as cutting toenails by rounding edges can lead to ingrown toenails, which can be dangerous for clients with diabetes.

Correct Answer: C

Rationale: The correct answer is C, bilateral crackles. Fluid in both lung bases on x-ray indicates pulmonary edema, causing crackles on auscultation. Fatigue (A) is a nonspecific symptom. Peripheral edema (B) is a sign of fluid retention in the extremities, not lungs. Jugular vein distention (D) indicates increased central venous pressure, which is not specific to lung fluid.

Correct Answer: C

Rationale: The correct answer is C: Position lower extremities below level of heart. This intervention helps improve blood flow and perfusion to the lower extremities by utilizing gravity to assist in venous return. This is crucial for clients at risk for ineffective tissue perfusion post-cardiac surgery. A: Restricting fluid intake may lead to dehydration, which can worsen tissue perfusion. B: Ensuring the client avoids prolonged sitting is important for preventing blood clots, but it does not directly address tissue perfusion. D: Instructing the client to avoid leg exercises may hinder circulation and exacerbate issues related to tissue perfusion.
