Q 23: Hypotensive shock may result from excessive blood levels of each of the following local anesthetics EXCEPT:
a. Cocaine
b. Procaine
c. Lidocaine
d. Tetracaine
e. Mepivacaine

Cocaine is the only local anesthetic that predictably produces vasoconstriction. Cocaine is also the only local anesthetic to block the reuptake of NE into adrenergic neurons, and thus potentiate the NE that has been released from nerve endings
