A patient in the postanesthesia recovery unit received ketamine (Ketalar) for right open reduction internal fixation surgery. What drug would be beneficial as a premedication to help minimize adverse reactions?

a. Thiopental sodium (Pentothal)
b. Sevoflurane (Ultane)
c. Atropine (Sal-Tropine)
d. Diazepam (Valium)

Question 2

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.

Answer to Question 1

ANS: D
To minimize the effects of ketamine, the patient should be premedicated with diazepam or midazolam to reduce the risk of an adverse reaction. Thiopental sodium would further sedate the patient. Sevoflurane would further complicate sedation and would not be indicated. Atropine would not reduce the risk of an adverse reaction.

Answer to Question 2

ANS: D
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.
