Answer 1

This question pertains to the use of isoproterenol and dopamine to manage ventricular arrhythmias and shock in a patient who has undergone a heart transplant.

Step-by-step explanation:

The subject of the question relates to the medical management of a patient who is experiencing ventricular arrhythmias and shock post heart transplant. Isoproterenol and dopamine are the medications ordered by the physician. Isoproterenol, a non-selective beta-adrenergic agonist, is usually administered to increase heart rate and improve myocardial contractility. Dopamine, on the other hand, acts predominantly on dopamine receptors but, at higher doses, also stimulates beta-1 adrenergic receptors, leading to increased cardiac contractility. Both medications can help support cardiac output in a patient with heart failure or shock.
