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


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

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




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

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

d. I should take this medication with high-fat foods to improve its action. CORRECT ANSWER: C
bj bj bj bj bj bj bj bj bj bj bj bj bj bj




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


when they reach the small intestine. There is usually some delay in onset of actions after taking
bj bj bj bj bj bj bj bj bj bj bj bj bj bj bj bj bj


these medications. Enteric-coated tablets should not be crushed or chewed, which would alter the
bj bj bj bj bj bj bj bj bj bj bj bj bj bj


time and location of absorption. Acidic foods will not enhance the absorption of the medication. The
bj bj bj bj bj bj bj bj bj bj bj bj bj bj bj bj


patient should not to eat high-fat food before ingesting an enteric-coated tablet, because high-fat
bj bj bj bj bj bj bj bj bj bj bj bj bj bj


foods decrease the absorption rate.

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


given by subcutaneous injection instead of by mouth. The nurse will explain that this is
bj bj bj bj bj bj bj bj bj bj bj bj bj bj bj


because
bj




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




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




c. digestive enzymes in the gastrointestinal tract prevent absorption.
bj bj bj bj bj bj bj




d. the oral form is less predictable with more adverse effects. CORRECT ANSWER: C
bj bj bj bj bj bj bj bj bj bj bj bj




Insulin, growth hormones, and other protein-based drugs are destroyed in the small intestine by
bj bj bj bj bj bj bj bj bj bj bj bj bj


digestive enzymes and must be given parenterally. Because insulin is destroyed by digestive
bj bj bj bj bj bj bj bj bj bj bj bj bj


enzymes, it would not make it to the liver for metabolism with a first-pass effect. Subcutaneous
bj bj bj bj bj bj bj bj bj bj bj bj bj bj bj bj


tissue has fewer blood vessels, so absorption is slower in such tissue. Insulin is given
bj bj bj bj bj bj bj bj bj bj bj bj bj bj bj


subcutaneously because it is desirable to have it absorb slowly.
