ATI PN Comprehensive Predictor 2024

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.

Correct Answer: A

Rationale: Filgrastim works by stimulating the production of white blood cells. Therefore, monitoring the white blood cell (WBC) count is essential to assess the effectiveness of the treatment. Choice B, serum potassium, is not directly affected by filgrastim therapy. Choice C, hemoglobin level, is important but not the primary indicator of filgrastim's effectiveness. Choice D, serum creatinine, is unrelated to the action of filgrastim and would not reflect its effectiveness.

Correct Answer: A

Rationale: The correct action for the nurse to take after administering an influenza virus immunization by the intradermal route is to avoid massaging the site. Massaging the site can spread the vaccine, potentially reducing its effectiveness. Rubbing the site in a circular motion or applying a bandage are not recommended actions as they can also interfere with the proper absorption of the vaccine.

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 correct answer is B: "Use a bed exit alarm system." For a client with dementia at risk for falls, a bed exit alarm system is beneficial as it alerts staff when the client is trying to get up, helping to reduce fall risks. Choice A, maintaining the client's bed in the lowest position, may not prevent falls as effectively as an alarm system. Choice C, assisting the client with ambulation every hour, may not be feasible and could disrupt the client's rest. Choice D, raising all 4 side rails for safety, can lead to restraint issues and is not recommended as a routine fall prevention measure.
