PLEASE PLEASE HELP ME!
Which of the following information is confirmed when the patient is in the preoperative process?

a. The name of the first school he or she attended
b. The color of the cast he or she prefers if his surgery requires a cast
c. Whether he or she walked to the surgery from home
D. Whether he or she has been nil per os

D.

Explanation:

Nil per os (NPO) means nothing by mouth. It is important to

know if the patient has eaten or drunk anythin prior to surgery to

prevent vomiting and possible aspiration

the ileocecal valve (also called bauhin valve), which limits the rate of food passage into the cecum and may prevent material from returning to the small intestine.
