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 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: B

Rationale: The correct intervention for a client with stomatitis is to encourage them to eat soft foods. Soft foods help prevent further irritation of the mouth, making it easier for the client to eat and reducing discomfort. Providing lemon-glycerin swabs could be too harsh on the already irritated mucosa. Avoiding toothpaste is relevant for clients with stomatitis to prevent further irritation. Instructing the client to use a mouthwash containing alcohol is contraindicated as alcohol can further irritate the mucosa.

Correct Answer: B

Rationale: The correct answer is to limit phosphorus and potassium intake for a client with chronic kidney disease. In renal insufficiency, the kidneys struggle to excrete these minerals, leading to their buildup in the blood, which can be harmful. Limiting phosphorus and potassium intake helps prevent further kidney damage and manage the progression of chronic kidney disease. Encouraging protein-rich foods (Choice C) may be counterproductive as excessive protein intake can burden the kidneys. Increasing potassium-rich foods (Choice A) is incorrect as high potassium levels can be detrimental in kidney disease. Increasing calcium-rich foods (Choice D) is not typically a focus in dietary teaching for chronic kidney disease unless there is a specific deficiency or need, as excessive calcium intake can also be harmful to kidney function.

Correct Answer: A

Rationale: The correct answer is A: Decerebrate posturing. Decerebrate posturing is an abnormal body posture characterized by rigid extension of the arms and legs, which indicates severe brainstem injury affecting the midbrain and pons. This posture suggests dysfunction or damage to neural pathways controlling muscle tone. Choice B, hypervigilance, is not typically associated with brainstem injury but rather with increased alertness and arousal. Choice C, absence of deep tendon reflexes, is not a specific finding related to brainstem injury. Choice D, a Glasgow Coma Scale score of 15, indicates a fully awake and alert state, which is not expected in a client with a brainstem injury.
