A patient receiving enteral feedings may be prescribed to be NPO, what does this mean for the patient?

Nothing by mouth

Nocturnal feedings only

Administer by mouth

Aspirate gastric contents

Answer and Explanation

The Correct Answer is A

a) Nothing by mouth: NPO stands for "Nil Per Os" in Latin, which means "nothing by mouth." This includes all food and fluids, and the patient would receive nutrition through other means such as enteral feedings.

b) Nocturnal feedings only: NPO refers to not taking anything by mouth at all, not just during certain times.

c) Administer by mouth: This would contradict the NPO order, which specifies that nothing should be taken orally.

d) Aspirate gastric contents: This is a procedure used for other purposes (like verifying placement of a tube), but it does not define what "NPO" means.
