Question

an adult with a healthy sleep cycle is most likely to enter rem sleep in which of the following ways?
a immediately after falling asleep
b after the dream stage is completed
c after cycling through the nrem sleep stages
d soon after falling asleep and then remain there for the majority of the night

Explanation:

The sleep cycle consists of non - rapid eye movement (NREM) stages (Stage 1, Stage 2, Stage 3) and rapid eye movement (REM) sleep. An adult with a healthy sleep cycle first goes through the NREM sleep stages and then enters REM sleep. Option A is incorrect because immediately after falling asleep, one enters NREM Stage 1. Option B is wrong as REM sleep is the stage where dreams mainly occur. Option D is incorrect as one does not remain in REM sleep for the majority of the night; the cycle repeats with alternating NREM and REM periods.

Answer:

C. after cycling through the NREM sleep stages
