Select the
TRUE statement.
A. During halothane anesthesia, a higher than normal dose of d-tubocurarine is required to produce skeletal muscle relaxation.
B. Succinylcholine has no potential for interaction with digitalis-like drugs.
C. Cyclobenzaprine is safe to use concurrently with a monoamine oxidase (MAO) inhibitor.
D. During treatment with an aminoglycoside antibiotic, less vecuronium is needed to produce skeletal muscle relaxation.
E. In patients with a history of malignant hyperthermia, succinylcholine can safely be used for endotracheal intubation prior to halothane-induced anesthesia.
