C) Isoproterenol (Isuprel)
RATIONALE
Terbutaline, pirbuterol, and metaproterenol are all beta 2 stimulants. Isoproterenol stimulates beta 1 and beta 2 receptors, and therefore should not be used with clients with tachydysrhythmias. In order to answer this question, recall knowledge of beta 1 and beta 2 stimulants and their effects on the heart. Use the process of elimination, and exclude those medications of the same category, to be led to the correct choice.
