Pediatric HESI Test Bank

Correct Answer: B

Rationale: Chest tubes are used to drain air and fluid from the chest cavity to prevent complications such as pneumothorax or cardiac tamponade after surgery. Choice A is incorrect as chest tubes are not used to increase tidal volumes. Choice C is incorrect as chest tubes do not maintain positive intrapleural pressure; instead, they assist in removing excess air or fluid. Choice D is incorrect as chest tubes do not regulate pressure on the pericardium and chest wall; they primarily aid in drainage.

Correct Answer: A

Rationale: Abdominal swelling is frequently the initial assessment finding associated with a Wilms tumor. This swelling is caused by the tumor's mass in the kidney, leading to abdominal distension. Weight gain (Choice B) is less likely as a primary finding, as it may occur later due to tumor growth or fluid retention. Hypotension (Choice C) is not typically associated with Wilms tumor unless severe complications like hemorrhage develop. Increased urinary output (Choice D) is not a common initial finding; instead, hematuria or other urinary changes may be observed later in the disease process.

Correct Answer: C

Rationale: Discussing any other observed behaviors can help identify patterns or potential issues, which is crucial for assessing the infant's overall well-being. Option A about accidents and prevention is not pertinent to the situation described. Option B regarding playtime with other children does not address the infant's behavior and potential causes. Option D about food and vitamins is not relevant to the presented scenario and the observed behavior of the infant.

Correct Answer: B

Rationale: Chest tubes are used to drain air and fluid from the chest cavity to prevent complications such as pneumothorax or cardiac tamponade after surgery. Choice A is incorrect as chest tubes are not used to increase tidal volumes. Choice C is incorrect as chest tubes do not maintain positive intrapleural pressure; instead, they assist in removing excess air or fluid. Choice D is incorrect as chest tubes do not regulate pressure on the pericardium and chest wall; they primarily aid in drainage.

Correct Answer: D

Rationale: Promoting perianal skin integrity is crucial when caring for a young child with severe diarrhea as it helps prevent skin breakdown from the irritation caused by frequent stooling. Maintaining the IV (Choice A) may be necessary but is not directly related to managing perianal skin integrity. Taking daily weights (Choice B) is important for monitoring fluid status but not the priority when addressing perianal skin integrity. While replacing lost calories (Choice C) is essential, promoting perianal skin integrity takes precedence in preventing complications associated with skin breakdown.
