Her blood pressure is 80/50 mm Hg, pulse rate is 40 beats/min and weak, and respirations are 22 breaths/min and regular. She is receiving supplemental oxygen, and an IV line has been established in the extremity opposite the shunt. The ECG reveals sinus bradycardia in lead II. Your next action should be to:
A) obtain a 12-lead ECG tracing.
B) administer 0.5 mg of atropine sulfate.
C) administer a 20-mL/kg fluid bolus.
D) administer calcium and bicarbonate.
