Gastrointestinal System Nursing Exam Questions

Correct Answer: B

Rationale: Water-soluble lubricant is used to lubricate 3 to 4 inches of the tube at the insertion end. An oil lubricant is not used because if the tube accidentally goes into the bronchus, pneumonia can develop. Half-inch tape is used to secure the tube after the correct placement is verified. A 50-mL catheter tip syringe is used to aspirate gastric contents to confirm placement. The client will be asked to take a sip of water through a straw to help with the passage of the tube.

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.

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: C

Rationale: Although no special diet is required to treat viral hepatitis, it is generally recommended that clients consume a diet with low-fat content because fat may be tolerated poorly due to decreased bile production. Small, frequent meals are preferable and may prevent nausea. Appetite is often better in the morning, so it is easier to eat a good breakfast. An adequate fluid intake of 2500 to 3000 mL per day that includes nutritional juices is also important.

Correct Answer: B

Rationale: Serosanguineous drainage with a small amount of bile is expected from the Penrose drain for the first 24 hours. Drainage then decreases, and the drain is removed usually within 48 hours. The nurse does not need to notify the physician. A sterile dressing covers the site and should be changed to prevent infection and skin excoriation.
