HESI Pediatric Practice Exam

Correct Answer: C

Rationale: In a situation where an infant with tetralogy of Fallot is acutely cyanotic and hyperpneic, the priority action should be to place the infant in a knee-chest position. This position helps increase systemic vascular resistance, improving pulmonary blood flow and subsequently ameliorating the cyanosis and hyperpnea. It is a non-invasive and effective intervention that can be promptly implemented by the nurse to address the immediate respiratory distress.

Correct Answer: D

Rationale: In this scenario, the infant presenting with vomiting, lethargy, and projectile vomiting indicates a potential serious condition. Crying without tears is a sign of dehydration, a critical condition that can lead to life-threatening complications in infants. Dehydration can rapidly worsen an infant's condition, making prompt intervention crucial to prevent further complications.

Correct Answer: C

Rationale: The correct answer is C. Chest physiotherapy should not be performed right after meals to avoid inducing vomiting. It should be done before meals or at least 1 hour after for effective mucus clearance and to prevent any potential complications like vomiting.

Correct Answer: D

Rationale: Petechial rash can be a sign of a serious condition like meningitis, and the healthcare provider should be notified immediately.

Correct Answer: A

Rationale: In a child presenting with ear pain and fever, asking if the child has had a runny nose is crucial in assessing for possible ear infection causes. Respiratory infections can lead to secondary ear infections, so exploring symptoms related to upper respiratory tract infections, like a runny nose, can help in the evaluation and management of the child's condition.
