Final answer:
If a child with SVT is stable, you can observe and provide reassurance if they are asymptomatic. If they are symptomatic, you can try vagal maneuvers and administer medications or perform cardioversion if necessary.
Step-by-step explanation:
If a child with SVT (supraventricular tachycardia) is stable, there are several steps you can take. First, determine if the child is symptomatic or asymptomatic.
If the child is asymptomatic and there are no concerning findings on physical examination, you can observe and provide reassurance.
However, if the child is symptomatic, you can try vagal maneuvers such as the Valsalva maneuver or carotid massage to restore normal heart rhythm.
If these maneuvers are unsuccessful, you may need to administer medications or perform a synchronized cardioversion to convert the child's heart rhythm back to normal.
