The nurse is admitting an infant diagnosed with supraventricular tachycardia. Which intervention is the priority for this infant?
1. Apply ice to the face.
2. Perform Valsalva's maneuver.
3. Administer a beta blocker.
4. Prepare for cardioversion.
Correct Answer: 1
Rationale: Supraventricular tachycardia episodes are initially treated with vagal maneuvers to slow the heart rate when the infant is stable. In stable infants, the application of ice or iced saline solution to the face can reduce the heart rate. The infant is not capable of performing Valsalva's maneuver. Calcium channel blockers, not beta blockers, are the drugs of choice. Cardioversion is used in an urgent situation, but is not typically the initial treatment.
