Epinephrine stimulates adrenergic receptors; what sites does the drug stimulate?
  1. Alpha sites more than beta sites
  2. Beta sites more than alpha sites
  3. Alpha and beta sites equally
  4. Neither alpha nor beta sites
Explanation
Answer - C - Epinephrine stimulates alpha and beta sites equally. During cardiac arrest the effects to the alpha sites are most desirable due to them increasing vasoconstriction, which will increase perfusion pressures generated during administration of external chest compressions. This drug is classified as a sympathomimetic - stimulates the sympathetic nervous system.
