ATI PN Comprehensive Predictor 2024

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.

Correct Answer: C

Rationale: The most appropriate position for a client post-lumbar puncture is the supine position. Placing the client in a supine position helps prevent spinal headaches by allowing the puncture site to seal effectively and reducing the risk of cerebrospinal fluid leakage. High Fowler's position, prone position, and sitting position are not recommended after a lumbar puncture as they may increase the risk of complications like spinal headaches.

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: 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: B

Rationale: The most important teaching point for a client with diabetes being discharged is to administer insulin before meals as prescribed. This is crucial for managing blood sugar levels effectively and preventing complications. Monitoring blood sugar levels once in the morning (Choice A) is not sufficient for proper diabetes management, as levels can fluctuate throughout the day. Taking medication only when feeling unwell (Choice C) is not recommended as diabetes treatment is based on a regular schedule. Monitoring glucose levels weekly (Choice D) is not frequent enough to provide the necessary information for managing diabetes on a day-to-day basis.
