What is the best nursing intervention for a patient with hyperkalemia?

Correct Answer: A

Rationale: The correct answer is to administer potassium-wasting diuretics. Hyperkalemia, which is high potassium levels, is managed by promoting the excretion of potassium from the body. Potassium-wasting diuretics help the kidneys eliminate excess potassium. Encouraging a low-potassium diet (choice B) is important for long-term management but not the immediate intervention for hyperkalemia. Administering potassium supplements (choice C) would worsen the condition by further increasing potassium levels. Administering IV fluids (choice D) may help with hydration but does not directly address the high potassium levels characteristic of hyperkalemia.

Correct Answer: A

Rationale: The correct intervention for a patient experiencing hypovolemic shock is to administer IV fluids. In hypovolemic shock, there is a significant loss of circulating blood volume leading to inadequate perfusion to tissues. Administering IV fluids is crucial to restore blood volume and improve tissue perfusion. Monitoring blood pressure (choice B) is important but not the primary intervention in hypovolemic shock. Placing the patient in Trendelenburg position (choice C) can worsen outcomes by increasing intracranial pressure and is no longer recommended. Administering oxygen (choice D) is beneficial for many conditions but does not address the underlying issue of inadequate circulating blood volume in hypovolemic shock.

Correct Answer: A

Rationale: The correct answer is to administer oxygen. In a patient experiencing respiratory distress, the primary concern is ensuring an adequate oxygen supply to the body. By administering oxygen, you can help improve oxygenation, which is crucial for the patient's overall well-being. Assessing airway patency is important but administering oxygen takes precedence as it directly addresses the oxygenation concern. Monitoring oxygen saturation is also essential, but the immediate action should be to provide oxygen. Calling for assistance can be important but is not the first priority when dealing with a patient in respiratory distress.

Correct Answer: D

Rationale: The LPN should question the assignment of replacing the PCA pump cartridge and tubing as it is outside the LPN's scope of practice. LPNs are not trained to handle tasks related to PCA pumps, which involve medication administration and monitoring that are typically within the RN's responsibilities. Assisting a postop client with an incentive spirometer (Choice A), collecting a clean catch urine specimen (Choice B), and providing nasopharyngeal suctioning for a client with pneumonia (Choice C) are all tasks that fall within the LPN's scope of practice and do not require questioning by the LPN.

Correct Answer: D

Rationale: The correct answer is D: Non-maleficence. Non-maleficence refers to the ethical principle of avoiding harm. In this scenario, the nurse questions the medication prescription to prevent potential harm to the client, demonstrating the principle of non-maleficence. Choice A, fidelity, pertains to being faithful and keeping promises, which is not the focus of the scenario. Choice B, autonomy, relates to respecting a client's right to make decisions about their care, not the nurse's actions. Choice C, justice, involves fairness and equal treatment, which is not directly applicable to the nurse questioning a medication prescription to prevent harm.
