,3. The nurse is teaching a patient who will be discharged home with a prescription for an enteric-
1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1



1 coated tablet. Which statement by the patient indicates understanding of the teaching?
1 1 1 1 1 1 1 1 1 1 1



a. I may crush the tablet and put it in applesauce to improve absorption.
1 1 1 1 1 1 1 1 1 1 1 1



b. I should consume acidic foods to enhance absorption of this medication.
1 1 1 1 1 1 1 1 1 1



c. I should expect a delay in onset of the drugs effects after taking the tablet.
1 1 1 1 1 1 1 1 1 1 1 1 1 1



d. I should take this medication with high-
1 1 1 1 1 1



fat foods to improve its action. ANS: C

Enteric-
coated tablets resist disintegration in the acidic environment of the stomach and disintegrate when t

hey reach the small intestine. There is usually some delay in onset of actions after taking these medi

cations. Enteric- 1



coated tablets should not be crushed or chewed, which would alter the time and location of absorptio
1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1

-fat food before ingesting an enteric-coated tablet, because high-
1 1 1 1 1 1 1 1



fat foods decrease the absorption rate.

4. A patient who is newly diagnosed with type 1 diabetes mellitus asks why insulin must be given
1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1



by subcutaneous injection instead of by mouth. The nurse will explain that this is because
1 1 1 1 1 1 1 1 1 1 1 1 1 1



a. absorption is diminished by the first-pass effects in the liver. 1 1 1 1 1 1 1 1 1



b. absorption is faster when insulin is given subcutaneously. 1 1 1 1 1 1 1



c. digestive enzymes in the gastrointestinal tract prevent absorption.

d. the oral form is less predictable with more adverse effects. A

Insulin, growth hormones, and other protein-1 1 1 1 1



based drugs are destroyed in the small intestine by digestive enzymes and must be given parenterall
1 1 1 1 1 1 1 1 1 1 1 1 1 1 1



y. Because insulin is destroyed by digestive enzymes, it would not make it to the liver for metabolis
1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1



m with a first-
1 1 1



pass effect. Subcutaneous tissue has fewer blood vessels, so absorption is slower in such tissue. Ins
1 1 1 1 1 1 1 1 1 1 1 1 1 1 1



ulin is given subcutaneously because it is desirable to have it absorb slowly.
