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: D

Rationale: The correct answer is to keep the cord stump dry until it falls off. This is important to promote natural healing and prevent infection. Choice A is incorrect because cleaning the cord with hydrogen peroxide daily can actually delay healing and increase the risk of infection. Choice B is incorrect as the cord stump typically falls off within 1 to 3 weeks, not in 5 days. Choice C is incorrect because a cord stump turning black is a normal part of the healing process and does not necessarily indicate a problem requiring immediate provider contact.

Correct Answer: A

Rationale: Correct! When assessing for dehydration in a pediatric patient, checking for dry mouth and decreased urine output are crucial indicators. Dry mouth indicates reduced fluid intake or dehydration, while decreased urine output suggests decreased renal perfusion secondary to dehydration. Skin turgor and capillary refill are more indicative of perfusion status rather than dehydration specifically. Lethargy and irritability can be present in dehydrated patients but are more general signs of illness. Monitoring blood pressure and heart rate are important in assessing dehydration severity but are not the initial signs used for assessment.

Correct Answer: B

Rationale: The correct answer is B: 'Keep oxygen equipment at least 6 feet away from heat sources.' It is crucial to keep oxygen equipment away from heat sources to prevent fire hazards. Option A is incorrect as oxygen tanks should be stored in an upright position. Option C is wrong because smoking near oxygen equipment poses a significant fire risk. Option D is also incorrect as fluid intake should not be restricted while using oxygen therapy; in fact, it is important to maintain adequate hydration.

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.
