Following the administration of adenosine, the paramedic should be aware that:

a. The patient may be hypotensive and hypovolemic
b. The patient will require a drip infusion
c. The patient may experience arrhythmias including transient asystole
d. Sympathomimetics may be necessary to counteract the long-term effects of adenosine

c
Rationale: a. Hypotension may be transient, but will not result in hypovolemia.
b. In the acute setting, there is not an indication for a drip infusion of adenosine.
c. Correct.
d. The half-life of adenosine precludes long term effects.
