further information is most important for the nurse to obtain from the
prescriber?
A. "How many refills are needed?"
B. "Do you want the drug given orally or intravenously?"
C. "Which brand of drug should be given, or is this a generic drug?

The route of administration was not indicated in the original order
A patient is to receive an acetaminophen (Tylenol) suppository for an
elevated temperature of 102.8° F. The nurse must take the following actions
EXCEPT
A. Ask if the patient is having any diarrhea.
B. Put on a pair of sterile gloves.
C. Place the patient in the Sims' position. Ask the patient to take a deep
breath and bear down.
D. Push the suppository into the rectum about 1 inch. - CORRECT ANSWERS-
B. Put on a pair of sterile gloves
This would be a nice touch, but all that is required is clean gloves. When
patient has diarrhea, it is not appropriate to give drug rectally. Asking patient
to bear down can ease insertion by relaxing anal muscles and allowing
suppository passing, besides, when patient is bearing down, the presence of
stool can be identified. The suppository won't be effective if it is buried in the
feces. Depth of insertion makes difference in route of administration (enteral
vs. percutaneous or rectal), which in turns affects the amount of absorption.
Drug given through enteral route is affected by first pass loss, while drug
given through rectal is not.
