Correct Answer: C

Rationale: The correct intervention for hyperkalemia is to administer insulin (Choice C). Insulin drives potassium into cells, lowering serum potassium levels. This is effective in acutely reducing high potassium levels. Administering calcium gluconate (Choice A) is used for stabilizing cardiac membranes in hyperkalemia but does not lower potassium levels. Sodium bicarbonate (Choice B) is used for metabolic acidosis, not hyperkalemia. Furosemide (Choice D) is a loop diuretic that can lead to potassium loss but is not the primary intervention for hyperkalemia.

Correct Answer: B

Rationale: The correct answer is B: Increase potassium intake. Potassium helps to lower blood pressure by counteracting the effects of sodium. This dietary change is crucial for managing hypertension. Increasing sodium intake (choice A) is incorrect as it can lead to increased blood pressure. Increasing fiber intake (choice C) is beneficial for overall health but not specifically for hypertension. Increasing alcohol intake (choice D) is harmful and can worsen hypertension. Prioritizing increasing potassium intake is essential for effectively managing hypertension.

Correct Answer: D

Rationale: The correct answer is D: To treat human responses. This goal aligns with the nursing profession's focus on addressing the holistic needs of individuals. Nurses aim to understand and manage patients' emotional, physical, and psychological responses to illness or treatment. By treating human responses, nurses can improve overall well-being. A: Providing cost-effective care is important but not a broad goal within nursing. It is a component of efficient healthcare delivery. B: Forming broad nursing diagnoses is a part of the nursing process, not a broad goal in itself. C: Promoting self-care is crucial in nursing practice, but it is more of a specific intervention rather than a broad goal encompassing the entire profession.

Correct Answer: A

Rationale: The correct answer is A: Apply a splint. This is the first step because immobilizing the affected limb helps prevent further injury and reduces pain. Administering fluids (B) and oxygen (C) are important but not the priority in this situation. Elevating the limb (D) can wait until the fracture is stabilized.

Correct Answer: A

Rationale: The correct answer is A: Administer anticoagulants. Anticoagulants are the primary treatment for DVT as they prevent blood clots from getting bigger and reduce the risk of new clots forming. This helps prevent complications like pulmonary embolism. Elevating the leg and applying compression (option B) can help with symptoms but do not address the underlying cause. Providing anticoagulant therapy (option C) is similar to the correct answer but lacks specificity. Applying compression stockings (option D) can help prevent complications but do not treat the existing clot.
