Quizplus · Accepted Answer

Atropine is a medication that stimulates the sympathetic nervous system by blocking the action of acetylcholine. This leads to an increase in heart rate by increasing the firing rate of the sinoatrial (SA) node. Therefore, an increase in the patient's heart rate would be the expected finding after administering atropine. Options A and B are not necessarily relevant to the administration of atropine for AV block, and option D may not always be a reliable indicator of medication effectiveness.
