C
Intravenous calcium gluconate, 10 ml. of 10% solution
D
Intravenous atropine, 0.5 mg
High-Yield Explanation
The recommended treatment for asystole is the administration of atropine. If atropine is unsuccessful epinephrine is given. Ultimately cardiac pacing is necessary if atropine and epinephrine do not establish an adequate hea rate. Calcium has no clear role in treating asystole.
