Answer to Question 1

A, D, E
Nitrous oxide is an inhalation agent with high analgesic potency. It is not likely to precipitate malignant hyperthermia. It can significantly reduce the dose of the primary anesthetic by as much as 50 or more. It does not have high anesthetic potency, so it cannot be used alone to induce anesthesia. It is more likely to cause postoperative nausea and vomiting.

Answer to Question 2

D
Although neuromuscular blockers can paralyze all skeletal muscles, not all muscles are affected at once. The last muscles affected by neuromuscular blockers are the muscles of respiration, in-cluding the intercostals and the diaphragm. The first to become paralyzed are the levator muscle of the eyelids and the muscles of mastication. Paralysis occurs next in the muscles of the limbs, abdomen, and glottis.
