Why will the nurse administer a small dose of nondepolarizing neuromuscular junction (NMJ) blocker before administering succinylcholine?
A) To reduce discomfort of depolarization of muscles
B) To reduce the risk of malignant hyperthermia
C) To reduce negative effects of dantrolene
D) To increase the duration of effect for succinylcholine
A
Feedback:
Succinylcholine is associated with muscle pain related to the initial muscle contraction reaction. A nondepolarizing NMJ blocker may be given first to prevent some of these contractions and the associated discomfort. Administering a small dose of nondepolarizing NMJ blocker will not reduce the risk of malignant hyperthermia or increase the duration of effects. Dantrolene is a drug given to treat malignant hyperthermia.
