The nurse is caring for a client who suffered a stroke three days ago, and is assessing the client's state of arousal. The nurse knows that the part of the body responsible for a person being alert or aroused is which of the following?
A) Reticular activating system
B) Renin-angiotensin-aldosterone system
C) Cranial nerves
D) Adrenal glands
Ans: A
The reticular activating system (RAS) mediates arousal. The adrenal glands are endocrine glands that have many functions, but do not control arousal or alertness. The renin-angiotensin-aldosterone system has to do with fluid balance and blood pressure. The cranial nerves have a role in many of the body's abilities, but not arousal.
