Correct Answer: B

Rationale: The correct intervention for a patient receiving a blood transfusion is to monitor the patient for signs of circulatory overload. This is crucial to prevent fluid overload, which can lead to serious complications. Administering antihistamines is not a routine intervention during blood transfusions unless the patient shows signs of an allergic reaction. Ensuring the completion of the blood transfusion within a specific time frame is not as critical as monitoring for circulatory overload. Checking vital signs every 30 minutes is essential, but the specific focus should be on monitoring for signs of circulatory overload.

Correct Answer: B

Rationale: The most effective intervention in preventing deep vein thrombosis (DVT) in a postoperative patient is to encourage early ambulation and leg exercises. Early ambulation helps promote circulation, preventing stasis and reducing the risk of blood clot formation. Encouraging the patient to drink plenty of fluids (choice A) is important for overall health but is not the most effective intervention for preventing DVT. Administering anticoagulants (choice C) is a valuable intervention in some cases, but it may not be suitable for all postoperative patients. Applying compression stockings (choice D) can help prevent DVT but is generally not as effective as early ambulation and leg exercises in postoperative patients.

Correct Answer: C

Rationale: When a patient is immobile, the nurse should assess for psychosocial aspects, including a loss of hope and increased risk of depression. While issues like weight loss (choice A), loss of bone mass (choice B), and loss of strength (choice D) can also occur due to immobility, the primary concern in this scenario is the patient's mental and emotional well-being, making 'Loss of hope' the correct answer.

Correct Answer: B

Rationale: The correct answer is B. Beneficence is the ethical principle of doing good or acting in the best interest of the client. Preventing harm by providing accurate information and necessary care aligns with the principle of beneficence, as it focuses on promoting the well-being and safety of the client. Choices A, C, and D do not directly reflect the concept of beneficence. Ensuring all clients are treated fairly relates more to justice, allowing the client to refuse treatment pertains to autonomy, and ensuring the client's family agrees with the treatment involves collaboration and communication but not specifically beneficence.

Correct Answer: B

Rationale: The most critical information to include when providing discharge instructions for a patient with diabetes is teaching them how to monitor their blood sugar levels. This empowers the patient to actively manage their condition, make informed decisions about their diet and medication, and prevent complications. Encouraging a high-carbohydrate diet (Choice A) can be detrimental for diabetic patients as it may lead to unstable blood sugar levels. While regular exercise (Choice C) is important in diabetes management, monitoring blood sugar levels takes precedence. Providing a list of restricted foods (Choice D) is relevant but not as crucial as teaching the patient how to monitor their blood sugar levels.
