A patient receives a neuromuscular blocking agent as an adjunct to inhalation anesthesia. When caring for this patient, it is important for the nurse to remember that neuromuscular blocking agents:
A) cause vagal slowing of the heart.
B) increase the required dose of inhalation anesthetics.
C) increase the depth of unconsciousness.
D) prevent contraction of the diaphragm.

Question

Quizplus · Accepted Answer

Neuromuscular blocking agents enhance skeletal muscle relaxation so that the dose of inhalation anesthetics can be reduced to a safer amount. Because these drugs prevent contraction of all skeletal muscles, including the diaphragm, mechanical ventilation is required to support respiration. These agents do not cause vagal slowing of the heart. They reduce the required dose of inhalation agents. They do not affect the level of consciousness.
