CAN ANYONE HELP ME ANSWER THIS QUESTION!? I'VE READ THE QUESTION OVER AND OVER BUT IT IS CONFUSING ME....
At first the subject had difficulty falling asleep in the sleep lab, but finally drifted into sleep and was not awakened when a student researcher knocked a can of soda off of the desk. The EEG is displaying a slow regular pattern with occasional sleep spindles. The researchers feel confident that the subject is:
a)about to wake up
b)now in stage 2 of the sleep cycle.
c)dreaming.
d)in REM sleep.
The question is asking what sleep cycle this subject is in.
then the answer is B, I assume. right?
I don't know. Check your text.
Stage N2 is characterized by sleep spindles ranging from 11 to 16 Hz (most commonly 12–14 Hz) and K-complexes. During this stage, muscular activity as measured by EMG decreases, and conscious awareness of the external environment disappears. This stage occupies 45–55% of total sleep in adults.
To answer this question, it is important to understand the stages of the sleep cycle and focus on the information provided in the scenario.
The sleep cycle consists of several stages, including stage 1, stage 2, stage 3, and Rapid Eye Movement (REM) sleep. Each stage has distinct characteristics that can be observed using an electroencephalogram (EEG).
In the given scenario, the subject initially had difficulty falling asleep but eventually drifted into sleep. This suggests that the subject progressed through stage 1 and entered stage 2 of the sleep cycle. Stage 2 is characterized by a further decrease in brain activity, as well as the presence of specific brain wave patterns known as "sleep spindles." The scenario explicitly mentions the presence of sleep spindles on the EEG, which is a characteristic of stage 2 sleep.
Based on this information, the answer to the question is:
b) now in stage 2 of the sleep cycle.
It is important to carefully read the scenario provided and pay attention to the key details, such as the mention of sleep spindles on the EEG, in order to determine the correct answer.
