Correct Answer: A

Rationale: Cimetidine (Tagamet) a Histamine H2 receptor antagonist, will decrease the secretion of gastric acid. Sucralfate (Carafate) promotes healing by coating the ulcer. Antacids neutralize acid in the stomach. Omeprazole (Prilosec) inhibits gastric acid secretion.

Correct Answer: B

Rationale: Cigarette smoking should be avoided because of its stimulatory effect on gastric secretions. Nicotine also increases the release of epinephrine, which leads to vasoconstriction. The client may chew gum if desired. The client may eat chocolate if desired. A client with a peptic ulcer should check with the physician before taking any over-the-counter drug, but acetaminophen does not typically cause gastric irritation.

Correct Answer: B

Rationale: Lactulose is prescribed for the client with hepatic encephalopathy to reduce bacterial breakdown of protein in the bowel. The medication creates an acidic environment in the bowel and causes the ammonia to leave the bloodstream and enter the colon. Ammonia then becomes trapped in the bowel. Lactulose also has a laxative effect that allows for the elimination of the ammonia.

Correct Answer: A

Rationale: The initial way to determine if a nasogastric tube is in the stomach is to apply suction to the tube with a syringe and observe for the return of stomach contents. Then the pH of the aspirate can be measured. This is the method of choice. One would not irrigate until tube placement is confirmed. Observing for air bubbles when the free end of the tube is placed under water is an unacceptable, unsafe method of determining tube placement. Another method is to instill air into the tube with a syringe while auscultating over the epigastric area. Hearing the air enter the stomach helps ensure proper placement, but the method is not foolproof and is no longer considered an effective or preferred way to determine placement.

Correct Answer: C

Rationale: The lower esophageal sphincter is a functional sphincter that normally remains closed except when food or fluids are swallowed. If relaxation of this sphincter occurs, the client could experience symptoms of gastroesophageal reflux disease.
