HESI Practice Test Pediatrics

Correct Answer: B

Rationale: Auscultating the heart and lungs while the infant is held can provide important diagnostic information in assessing the cardiac and respiratory status of the infant who had surgical correction for tetralogy of Fallot. This intervention can help the nurse identify any abnormal heart or lung sounds, which may indicate complications or issues that need further evaluation or intervention.

Correct Answer: B

Rationale: Administering the scheduled dose is appropriate in this scenario since the heart rate of 128 bpm is within an acceptable range for a 2-year-old child with heart failure. Monitoring for signs of digoxin toxicity is important; however, the immediate action required is to administer the scheduled dose as prescribed based on the heart rate assessment.

Correct Answer: D

Rationale: Kussmaul respirations are deep, rapid breathing patterns observed in metabolic acidosis, such as diabetic ketoacidosis. In this condition, the body tries to compensate for the acidic environment by increasing the respiratory rate to eliminate excess carbon dioxide (CO2) and decrease the acid levels, thereby helping to correct the acid-base imbalance. Therefore, the correct answer is metabolic acidosis.

Correct Answer: C
