Pediatric HESI Test Bank

Correct Answer: C

Rationale: The correct answer is C: Right ventricular hypertrophy, ventricular septal defect, pulmonic stenosis, and overriding aorta are the cardiac defects associated with Tetralogy of Fallot. In Tetralogy of Fallot, these specific abnormalities contribute to the classic features of the condition. Choice A is incorrect as it includes mitral valve stenosis, which is not typically part of Tetralogy of Fallot. Choice B describes transposition of the great arteries, not Tetralogy of Fallot. Choice D mentions an altered connection between the pulmonary artery and the aorta, which is not a defining characteristic of Tetralogy of Fallot.

Correct Answer: A

Rationale: The correct answer is to rotate injection sites. This practice helps prevent lipodystrophy, a localized loss of fat tissue that can affect insulin absorption. By rotating sites, the child can avoid developing lumps or indentations in the skin where insulin is repeatedly injected. Administering insulin before meals (choice B) may be necessary for certain types of insulin but is not the priority when teaching about insulin administration. Storing insulin in the refrigerator (choice C) is important for maintaining its potency, but it is not the primary emphasis when teaching about insulin administration. Administering insulin at bedtime (choice D) may be necessary based on the child's insulin regimen but is not the primary consideration for teaching injection techniques and site rotation.

Correct Answer: A

Rationale: In this scenario, the infant is showing signs of shock with increased work of breathing. Lowering the extremities helps improve venous return to the heart, cardiac output, and oxygenation by reducing the pressure on the diaphragm. This action can alleviate the respiratory distress and is a critical step to take in a child with signs of shock. Beginning positive pressure ventilations (Choice B) should be considered if the infant's respiratory distress worsens despite lowering the extremities. Placing a nasopharyngeal airway and increasing oxygen flow (Choice C) may not directly address the increased work of breathing or the underlying shock condition. Listening to the lungs with a stethoscope (Choice D) may provide information on lung sounds but does not address the immediate need to improve breathing in a child with signs of shock.

Correct Answer: C

Rationale: The correct answer is to measure the dose with a proper measuring device. Using a household spoon can lead to inaccurate dosing, which can be dangerous. Administering the medication with food or only when the child has a high fever are not the essential instructions related to the safe and effective administration of acetaminophen.

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.
