Your patient is a 32-year-old female, 30 weeks' pregnant, complaining of shortness of breath and palpitations. She is alert and oriented, though anxious; her skin is cool and moist, and her radial pulse is weak and rapid, but regular. HR = 180, BP = 100/72, RR = 24. The monitor shows supraventricular tachycardia. After applying oxygen by nonrebreather and starting an IV of normal saline, which of the following is most appropriate?

Question

Quizplus · Accepted Answer

Adenosine is the drug of choice for terminating supraventricular tachycardia. It acts by blocking the AV node, interrupting the reentry circuit causing the tachycardia. It is safe in pregnancy and can be administered in doses of 6 mg followed by 12 mg if needed. Amiodarone and cardioversion may be considered if adenosine fails, but they are not the initial treatments of choice. Transport without further intervention is not appropriate as the patient is experiencing a potentially life-threatening arrhythmia. Versed is not indicated for this situation.
