Answer to Question 1

ANS: B
Stage 3 (N3) and Stage 4 (N4) are the periods of deep sleep. N3 is characterized by very slow brain waves called delta waves interspersed with smaller, faster waves. In Stage 4 (N4), the EEG shows almost exclusively delta waves. In this type of sleep it is difficult to awaken the individual and muscle activity is very limited or may be completely absent. A person awakened from Stage 3 or 4 of sleep could be disoriented for a brief period of time before regaining awareness.

Answer to Question 2

ANS: A
In Stage 1 (N1 or Non-REM Stage 1), referred to as light sleep, the individual can be awakened easily. In this stage, brain waves slow and, on EEG, the slower wave pattern known as alpha waves appears. The individual at this point is likely to drift in and out of sleep and can be awakened easily. Sensations known as hypnagogic hallucinations can occur during this stage. A common sensation of this type is the feeling of falling. Uncontrolled muscle jerks sometimes occur at this stage along with sudden movements that can startle the individual and restore wakefulness.
