Answer to Question 1

C
The sympathetic nervous system predominates during REM sleep. Oxygen consumption increases, and cardiac output, blood pressure, heart rate, and respiratory rate may become erratic. NREM sleep is dominated by parasympathetic nervous system. Blood pressure, heart and respiratory rates, and the metabolic rate return to basal levels. About 80 of total daily growth stimulating hormone is released in NREM sleep.

Answer to Question 2

A
Nursing interventions that maintain normal rhythm of the daynight cycle, such as opening window blinds, should be encouraged.
