Pediatric HESI

Correct Answer: B

Rationale: The correct answer is B. Airway clearance exercises are essential for individuals with cystic fibrosis to prevent mucus buildup in their lungs. It is crucial to perform these exercises regularly, even when feeling well, to maintain lung health and prevent complications. Therefore, the statement indicating that the exercises are not needed if feeling okay shows a misunderstanding and requires further teaching.

Correct Answer: A

Rationale: Administering activated charcoal is the priority intervention as it binds with digoxin, preventing further absorption in the gastrointestinal tract. This helps reduce the amount of digoxin available for systemic circulation and minimizes its toxic effects.

Correct Answer: D

Rationale: A significant drop in heart rate and blood pressure should be reported immediately as it may indicate worsening of the congenital heart defect. A decrease in blood pressure to 70/40 is a critical finding that suggests potential cardiovascular compromise and requires urgent attention to prevent further deterioration.

Correct Answer: B

Rationale: Administering the scheduled dose is appropriate in this scenario as the heart rate of 128 bpm falls within the acceptable range for a two-year-old child with heart failure. It indicates that the child may benefit from the therapeutic effects of digoxin. Monitoring the heart rate closely after administration is essential to ensure the medication's effectiveness and safety.

Correct Answer: C

Rationale: The priority action for a 2-year-old child with croup and stridor is to administer nebulized epinephrine. This intervention helps reduce airway swelling, alleviate symptoms, and improve breathing by causing vasoconstriction and reducing upper airway edema.
