  1. An enteric-coated medication should be given.
  2. Medication will not be absorbed as easily because of the nausea.

Answer to Question 1

ANS: 2
To calculate this problem, the nurse should first convert the measurements to one system. Be-cause 1 grain = 60 mg, the nurse may multiply 1 by 60 to equal 90 mg. The nurse may then use the following formula for calculating a drug dosage:
90 mg
100 mg x 1 capsule = 0.9 capsules
Because 0.9 of a capsule cannot be administered, it is rounded to 1 capsule. The nurse will ad-minister 1 capsule.
Options 1 and 3 are not correct dosage calculations. Furthermore, capsules cannot be halved.
Option 4 is not a correct dosage calculation.

Answer to Question 2

ANS: 3
The parenteral route provides a means of administration when oral medications are contraindi-cated. Onset of action is quicker. There is less cause for embarrassment than with a rectal suppos-itory. An enteric-coated medication is given orally. Because the client is vomiting, the oral route should not be used. Nausea does not affect the rate of absorption. It is inaccurate to state that a rectal suppository must be administered. A rectal suppository is one option. The disadvantage of a rectal suppository is that insertion often causes embarrassment for the client. It is contraindi-cated if there is rectal bleeding or if the client had rectal surgery. Stool in the rectum can impair absorption.
