A nurse is discussing adenosine with a nursing student. Which statement by the student indicates a need for further teaching?
a. "Adenosine acts by suppressing action potentials in the SA and AV nodes."
b. "Adenosine can be used to prevent parox-ysmal supraventricular tachycardia and Wolff-Parkinson-White syndrome."
c. "Adenosine has a half-life that lasts only a few seconds and must be given intrave-nously."
d. "Adenosine is not effective for treating atrial fibrillation, atrial flutter, or ventri-cular dysrhythmias."
B
Adenosine is used to terminate paroxysmal supraventricular tachycardia (SVT) and Wolff-Parkinson-White (WPW) syndrome, not to prevent symptoms. Adenosine suppresses ac-tion potentials in the SA and AV nodes. Because it has a very short half-life of 1.5 to 10 seconds, it must be given IV bolus, as close to the heart as possible. Adenosine is not active against atrial fibrillation, atrial flutter, or ventricular dysrhythmias.
