Bradycardia during general anesthesia of dogs can be treated with intravenous atropine, usually at 0.01 to 0.02 mglkg Iv. If the bradycardia worsens after atropine administration, the most appropriate course of action is to:
a. repeat the dose after 1 or 2 minutes
b. wait for atropine to cause its sympathetic effect
c. cease administration of anesthetic and insufflate with oxygen
d. administer epinephrine intravenously
e. insert a transvenous pacemaker because the dog must have sick sinus syndrome
