The client is admitted with paroxysmal supraventricular tachycardia at a rate of 140 beats per minute. the client's blood pressure is 110/55 mm hg, and the client is asymptomatic except for a "fluttering feeling" in the chest. which treatments should the nurse be prepared to administer

The correct answers are: IV adenosine, IV beta blockers, IV amiodarone, or IV calcium channel blockers. Supraventricular tachycardia is a kind of abnormal heart rate and the pathology lies in the atria (hence supraventricular). This is seen in the ECG as narrow QRS complexes. While all the management is applicable for supraventricular tachycardia, the first line is IV adenosine to normalize the heart rate. If this doesn't work, then IV amiodarone can be the second line. After these interventions are done but with no avail, cardioversion should be done.
