The patient is scheduled to have an EEG to confirm the presence of a sleep disorder. The patient asks the nurse to describe Stage IV NREM sleep. What is the best response by the nurse?
1. "This is the lightest stage of sleep, and is profoundly affected by anxiety."
2. "Dreaming occurs here; without dreams you will be irritable and paranoid."
3. "This is the deepest stage of sleep; without it you will be tired and depressed."
4. "This stage comprises the greatest amount of sleep time, and is important."
Correct Answer: 3
Rationale: Stage IV NREM sleep is the deepest stage of sleep. Patients who are deprived of it experience depression and a feeling of apathy and fatigue. Dreaming occurs in REM sleep, not NREM sleep. Stage IV NREM sleep is the deepest stage of sleep, not the lightest stage of sleep. Stage II NREM sleep, not Stage IV NREM sleep, comprises the greatest amount of total sleep time.
