Pediatric HESI Test Bank

Correct Answer: A

Rationale: For a 4-year-old child scheduled for a myringotomy, explaining the procedure in simple terms is essential in helping the child understand what will happen during the surgery and reducing anxiety. Encouraging fluid intake, allowing the child to play with medical equipment, and using play therapy are not directly related to preparing the child for the myringotomy procedure. Therefore, these options are incorrect and not as beneficial as explaining the procedure in simple terms.

Correct Answer: D

Rationale: Promoting perianal skin integrity is crucial when caring for a young child with severe diarrhea to prevent skin breakdown from the irritation caused by frequent bowel movements. Maintaining the IV (Choice A) may be important for hydration but is not directly related to managing skin integrity. Taking daily weights (Choice B) is important for monitoring fluid balance but does not address the immediate need to prevent skin breakdown. While replacing lost calories (Choice C) is important, it is not the priority when a child is experiencing severe diarrhea and skin integrity is at risk.

Correct Answer: B

Rationale: Chest tubes are necessary after open-heart surgery to facilitate the drainage of air and fluid from the chest cavity. These tubes help prevent complications such as pneumothorax (accumulation of air in the pleural space) or cardiac tamponade (build-up of fluid in the pericardial sac), which can be serious postoperative issues. Options A, C, and D are incorrect because chest tubes are primarily used for draining purposes and not for increasing tidal volumes, maintaining positive intrapleural pressure, or regulating pressure on the pericardium and chest wall.

Correct Answer: B

Rationale: The best initial action during a tonic-clonic seizure is to place the child on the floor. This action helps prevent injury by providing a safe environment and allows for better management of the seizure episode. Attempting to open the jaw is not recommended as it may cause harm to the child or the nurse. Calling out for assistance is important but should not delay ensuring the child's safety first. Placing a pillow under the child's head is not advisable during a seizure as it can pose a risk of suffocation or choking.

Correct Answer: B

Rationale: The correct answer is providing respiratory therapy. In bronchiolitis, the priority is to maintain airway patency through interventions such as suctioning, positioning, and oxygen therapy. While bronchodilators may be used in some cases, they are not the initial priority. Monitoring oxygen saturation is important but comes after ensuring airway patency. Encouraging fluid intake is essential for hydration but is not the priority over maintaining a patent airway.
