Correct Answer: B

Rationale: The correct intervention to prevent venous thromboembolism in a postoperative client following hip replacement is to administer anticoagulant therapy as prescribed. Anticoagulants help prevent blood clots from forming. Instructing the client to perform ankle pumps helps prevent blood clots by promoting circulation. Maintaining the client in a prone position can increase the risk of venous stasis and thrombus formation. Encouraging the client to ambulate as tolerated also helps prevent venous thromboembolism by promoting blood flow and preventing stasis.

Correct Answer: D

Rationale: In cases of anaphylaxis, all of the listed interventions are crucial for effective management. Administering epinephrine is the primary treatment to reverse the allergic reaction rapidly. Providing oxygen ensures adequate oxygenation to vital organs, and monitoring the airway is essential to prevent obstruction and maintain a clear air passage. Therefore, all three interventions are necessary in managing anaphylaxis. Choices A, B, and C are not individually sufficient to address all aspects of anaphylaxis, making the comprehensive approach of 'All of the above' the correct answer.

Correct Answer: A

Rationale: The correct answer is A: High sodium diet and lack of physical activity. These are established risk factors for developing hypertension as they contribute to elevated blood pressure. Choice B, low potassium intake and excessive alcohol consumption, may also impact blood pressure but are not as strongly associated with hypertension as high sodium intake and lack of physical activity. Choice C, frequent exercise and a low cholesterol diet, are actually beneficial for reducing the risk of hypertension. Choice D, smoking and family history, are more closely linked to other health conditions such as cardiovascular diseases, rather than being primary risk factors for hypertension.

Correct Answer: D

Rationale: When managing a patient with diabetic ketoacidosis (DKA), it is crucial to administer insulin to lower blood sugar levels, administer IV fluids to correct dehydration and electrolyte imbalances, and monitor blood glucose levels regularly to ensure they are within the target range. Therefore, all of the above options are essential components of the comprehensive treatment plan for DKA. Administering insulin alone may lower blood sugar levels but will not address the fluid and electrolyte imbalances seen in DKA. Similarly, administering IV fluids alone may help with dehydration but will not address the high blood sugar levels or the need for insulin. Monitoring blood glucose alone is not sufficient to treat DKA; it must be accompanied by appropriate interventions to address the underlying causes and complications of the condition.
