MULTIPLE CHOICE

 

1. A patient who has been instructed to use a liquid antacid medication to treat gastrointestinal upset asks the nurse about how to take this medication. What information will the nurse include when teaching this patient?

a.	Take a laxative if constipation occurs.
b.	Take 60 minutes after meals and at bedtime.
c.	Take with at least 8 ounces of water to improve absorption.
d.	Take with milk to improve effectiveness.

 

 

ANS:  B

Since maximum acid secretion occurs after eating and at bedtime, antacids should be taken 1 to 3 hours after eating and at bedtime. Taking antacids before meals slows gastric emptying time and causes increased gastrointestinal (GI) secretions. Patients should not self-treat constipation or diarrhea. Patients should use 2 to 4 ounces of water when taking to ensure that the drug enters the stomach; more than that will increase GI secretions. Antacids should not be taken with milk or foods high in vitamin D.

2. A patient who has symptoms of peptic ulcer disease will undergo a test that requires drinking a liquid containing 13C urea and breathing into a container. The nurse will explain to the patient that this test is performed to

a.	assess the level of hydrochloric acid.
b.	detect H. pylori antibodies.
c.	measure the pH of gastric secretions.
d.	test for the presence of 13CO2.

 

 

ANS:  D

When H. pylori is suspected, a noninvasive test is performed by administering 13C urea which, in the presence of H. pylori, will release 13CO₂. The test does not measure the amount of HCl acid or the pH and does not detect H. pylori antibodies.

3. A patient is taking esomeprazole (Nexium) 15 mg per day to treat a duodenal ulcer. After 10 days of treatment, the patient reports that the pain has subsided. The nurse will counsel the patient to

a.	continue the medication for 4 more weeks.
b.	reduce the medication dose by half.
c.	stop taking the medication.
d.	take the medication every other day.

 

 

ANS:  A

With treatment, ulcer pain may subside in 10 days, but the healing process may take 1 to 2 months. Patients should be counseled to take the drug for the length of time prescribed. Reducing the dose or taking less frequently is not indicated.

4. A patient with a peptic ulcer has been diagnosed with H. pylori. The provider has ordered lansoprazole (Prevacid), clarithromycin (Biaxin), and metronidazole (Flagyl). The patient asks the nurse why two antibiotics are needed. The nurse will explain that two antibiotics

a.	allow for less toxic dosing.
b.	combat bacterial resistance.
c.	have synergistic effects.
d.	improve acid suppression.

 

 

ANS:  B

The use of two antibiotics when treating H. pylori peptic ulcer disease helps to combat bacterial resistance because H. pylori develops resistance rapidly. Giving two antibiotics, in this case, is not to reduce the dose or to cause synergistic effects. Antibiotics do not affect acid production.
