Answer:
A nursing instructor might distinguish sleep from rest by noting that sleep is a state of unconsciousness in which the body and mind are inactive and the brain is in a different state than when awake. During sleep, the body undergoes a number of physiological changes, such as decreased heart rate and breathing, and the brain goes through different stages of activity. Rest, on the other hand, refers to a state of relaxation or reduced activity, but does not necessarily involve unconsciousness or physiological changes. While both sleep and rest are important for maintaining physical and mental health, they are distinct states with different characteristics.
