Question

A patient's assessment findings include dizziness, shortness of breath, heart palpitations, and paroxysmal supraventricular tachycardia (PSVT). The nurse obtains a prescription for adenosine. Which statement is true about the medication?a. It is given as an intravenous push (IVP) over one to two minutes.b. It must be given through a central venous access device (CVAD).c. The medication decreases conduction through the AV node.d. Its half-life is 10 minutes.

Answer 1

Answer:

The answer is letter C. That is the true stament.

Explanation:

c. The medication decreases conduction through the AV node.

Because Adenosine stops PSVT by slowing the conduction through AV node.  A brief period of asystole is normal. Adenosine is given to the patient as an IVP over one to two seconds and then immediately followed by a fast 20ml normal saline flush. It might be given through  a peripheral IV, but the site should be as close to the heart as possible because of its short half-life, around 10 seconds.
