How can a healthcare professional reduce the risk of falls in elderly patients?

Correct Answer: D

Rationale: All of these interventions are crucial in reducing the risk of falls in elderly patients. Encouraging the use of assistive devices helps provide support and stability, clearing walkways minimizes tripping hazards, and ensuring proper lighting enhances visibility and reduces the chances of falls. Therefore, choosing 'All of the above' is the most appropriate answer as each intervention plays a significant role in fall prevention.

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.

Correct Answer: C

Rationale: The correct answer is 0.9% sodium chloride. This solution is isotonic and helps maintain electrolyte balance during irrigation, preventing fluid and electrolyte imbalances. Tap water (choice A) may cause electrolyte imbalances due to its hypotonic nature. Sterile water (choice B) is hypotonic and can lead to electrolyte disturbances. 0.45% sodium chloride (choice D) is hypotonic and may also disrupt electrolyte balance when used for irrigation.
