Answer to Question 1

ANS: B
Stage 3delta rhythm is a period of deep and restful sleep. Muscles are relaxed, heart rate and blood pressure fall, and breathing slows. No eye movement occurs.

Answer to Question 2

ANS: C
The nurse should associate a decrease in GABA with panic disorder. Enhancement of the GABA system is the mechanism of action by which benzodiazepines produce a calming effect, thus reducing anxiety. Alterations in the GABA system are also associated with movement disorders and epilepsy.
