Constipation

An older adult has been taking a calcium-based antacid on an increasingly frequent basis. When teaching this client, the nurse should include suggestions for the prevention of which adverse effect?

Constipation

The nurse should warn a client taking aluminum- and calcium-containing antacids about which adverse effects?

Constipation - The nurse should warn a client taking aluminum- and calcium-containing antacids about constipation, which can be associated with taking products containing either medication. Client taking magnesium- and sodium-containing antacids can have diarrhea. Dehydration can be seen with the use of diuretics. Increased flatulence can be seen with the use of fiber laxatives such as Metamucil.

A clinic nurse is planning care for a 68-year-old man who has been on omeprazole (Prilosec) therapy for heartburn for some time. Regarding the patient's safety, which of the following would be a priority nursing action?

Coordinate bone density testing for the patient.

A client is diagnosed with Helicobacter pylori infection. The health care provider will order amoxicillin and what other type of medication?

Proton pump inhibitors

A client taking metronidazole informs the nurse that the medication will be finished today and they plan on drinking alcohol at a party tonight. What response by the nurse would be most helpful to prevent complications?

"Drinking within the next couple of days could cause a severe reaction."

A nurse is teaching a client about omeprazole, which has been prescribed as part of a regimen to treat an H. pylori infection. What statement, made by the client, suggests that the client understands proper use of the drug?

"I need to swallow the drug whole." - Omeprazole, a proton pump inhibitor, must be swallowed whole; it should not be cut, crushed or chewed. The drug should be taken approximately an hour before a meal, not after a meal. Concomitant use of antacids is common, though the health care provider may instruct the client to take the two medications at different times during the day.

A client has been prescribed omeprazole by the primary health care provider. When the nurse asks whether the medication is providing relief, the client replies, "I think it's working quite well, and I've gotten in the routine of taking it every morning before breakfast." How should the nurse respond?

"I'm glad to hear that. It sounds like you're taking it exactly like it should be taken."

An older client has been prescribed omeprazole for the treatment of gastresophageal reflux disease (GERD). What explanation should the nurse provide when asked by the client why they are not being treated with famotidine?

"Proton pump inhibitors, like omeprazole, produce fewer adverse effects among the older population."

Which instruction would be most important to give to a client who is receiving omeprazole?

"Swallow the tablet whole with a large glass of water." - The medication should be swallowed whole with a large glass of water. It should not be chewed, crushed, or opened. Antacids, if prescribed, should be taken 1 hour before or 2 hours after the omeprazole.

A female client has GERD and is taking cimetidine. She continues to have gastric discomfort and asks whether she can take an antacid. Which is an appropriate response by the nurse?

"Yes, but be sure to wait at least 2 hours to take the antacid after you take the cimetidine." - If both cimetidine and antacids are prescribed, give them at least 2 hours apart to prevent decreased absorption of cimetidine. The nurse should advise the client to wait at least 2 hours between doses and to take the antacid after the cimetidine.

A nurse is teaching a client about his prescribed lansoprazole. The nurse instructs the client to take the drug at which time?

Antibiotics A PPI

A critical care nurse is preparing to administer an intragastric drip of an antacid to a client through a nasogastric tube. How should the nurse most accurately titrate the dose and frequency?

By aspirating stomach contents and measuring the pH

Ranitidine (Zantac) is preferred over cimetidine (Tagamet) therapy in critically ill clients due to decreased risk of which adverse effect?

Drug-drug interactions

Which medication reduces the secretion of gastric acid by inhibition of the hydrogen-potassium adenosine triphosphate (ATPase) enzyme system of the gastric parietal cells? Select all that apply.

Esomeprazole Lansoprazole The proton pump inhibitors, like esomeprazole and lansoprazole, reduce the secretion of gastric acid by inhibition of the hydrogen-potassium adenosine triphosphate enzyme system of the gastric parietal cells. Famotidine (Pepcid) and ranitidine are both histamine H2 antagonists decreasing stomach acid by inhibiting the action of H2 receptors in the stomach. Calcium carbonate is an acid neutralizer that reduces the pH of the acid in the stomach and duodenum.

There is a drug-drug interaction between the antipeptides and penicillin.

False

Which adverse effect is more likely to be caused by cimetidine than by other H2RAs?

Gynecomastia

A client is receiving sodium bicarbonate orally. Which of the following would lead the nurse to suspect that the client is developing systemic alkalosis? (Select all that apply.)

Inhibiting the secretion of gastric acid

A nurse assesses a client for signs and symptoms of tardive dyskinesia when the client is receiving which drug?

A nurse is reviewing information about proton pump inhibitors. The nurse recognizes that which of the following is available as an over-the-counter agent?

Omeprazole

Antacids have not been effective in managing a client's gastroesophageal reflux disease, so the health care provider is prescribing a proton pump inhibitor. Why might the health care provider prescribe a proton pump inhibitor (PPI) rather than a histamine2 receptor antagonist (H2RA)?

PPIs suppress acid more strongly and for a longer time.

A client is taking nonsteroidal anti-inflammatory agents for arthritis of the knees and hips. Which disease is a result of cellular destruction of the gastrointestinal tract from this medication?

Peptic ulcer disease - Cell destruction will occur from the ingestion of NSAIDs, which can lead to the development of peptic ulcer disease. Nonsteroidal anti-inflammatory agents do not cause esophageal cancer, bowel obstruction, or liver cancer.

Renal dysfunction

Drugs act in several ways on the secretions of the GI tract. Which action affects the GI secretions least?

Replaces secretions

A nurse is planning care for a 59-year-old woman who is on ranitidine therapy. The nurse is concerned for the client's safety. What would be an appropriate nursing diagnosis?

Risk for Injury related to drug-induced somnolence, dizziness, confusion, or hallucinations

A 75-year-old client is treating an ulcer with antacids. Based on the client's age, the nurse expects the health care provider to prescribe a dose of antacid that compares with the average prescribed dose in what way?

Smaller than the average prescribed dose - Smaller doses of antacids may be effective in older adults, because they usually secrete less gastric acid than younger adults do.

bone density

What is the benefit of adding proton pump inhibitors (PPIs) to the treatment regime treating an H. pylori bacterial infection?

decreases production of gastric secretions

The nurse is teaching a client about lansoprazole prescribed for treatment of gastric ulcer. By what mechanism of action does lansoprazole help treat the disease?

inhibiting acid secretion - Lansoprazole is a proton pump inhibitor. Drugs in this class (sometimes known as gastric acid pump inhibitors) suppress gastric acid secretion.

A male client tells the nurse that he takes antacid tablets several times each day. Knowing that the brand of antacid he uses contains calcium carbonate, the nurse cautions the client that overuse could place him at risk for:

metabolic alkalosis - Overuse of antacids containing calcium carbonate can cause alkalosis and raise urine pH.
