Gastrointestinal System Nursing Exam Questions
1. The nurse aspirates 40 mL of undigested formula from the client’s nasogastric tube. Before administering an intermittent tube feeding, the nurse understands that the 40 mL of gastric aspirate should be
- A. Discarded properly and recorded as output on the client’s intake and output record.
- B. Poured into the nasogastric tube through a syringe with the plunger removed.
- C. Mixed with the formula and poured into the nasogastric tube through a syringe with the plunger removed.
- D. Diluted with water and injected into the nasogastric tube by putting pressure on the plunger.
Correct answer: B
Rationale: After checking the residual feeding contents, the gastric contents are reinstalled into the stomach by removing the syringe bulb or plunger and pouring the gastric contents into the syringe and through the nasogastric tube. Gastric contents should be reinstalled to maintain the client’s electrolyte balance. The gastric contents should be poured into the nasogastric tube through a syringe without a plunger and not injected by putting pressure on the plunger. Gastric contents do not need to be mixed with water or should the contents be discarded.
2. Lactulose (Chronulac) is prescribed for a client with a diagnosis of hepatic encephalopathy. The nurse would determine that this medication has had a therapeutic effect if which of the following is noted?
- A. Increased red blood cell count
- B. Decreased serum ammonia level
- C. Increased protein level
- D. Decreased white blood cell level
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.
3. The client being treated for esophageal varices has a Sengstaken-Blakemore tube inserted to control the bleeding. The most important assessment is for the nurse to:
- A. Check that the hemostat is on the bedside
- B. Monitor IV fluids for the shift
- C. Regularly assess respiratory status
- D. Check that the balloon is deflated on a regular basis
Correct answer: C
Rationale: Regularly assessing respiratory status is crucial when a Sengstaken-Blakemore tube is inserted to control bleeding in esophageal varices.
4. Britney, a 20 y.o. student is admitted with acute pancreatitis. Which laboratory findings do you expect to be abnormal for this patient?
- A. Serum creatinine and BUN
- B. Alanine aminotransferase (ALT) and aspartate aminotransferase (AST)
- C. Serum amylase and lipase
- D. Cardiac enzymes
Correct answer: C
Rationale: Serum amylase and lipase levels are typically elevated in patients with acute pancreatitis.
5. Vasopressin (Pitressin) therapy is prescribed for a client with a diagnosis of bleeding esophageal varices. The nurse is preparing to administer the medication to the client. Which of the following essential items is needed during the administration of this medication?
- A. A cardiac monitor
- B. An intubation set
- C. A suction setup
- D. A tracheotomy set
Correct answer: A
Rationale: The major action of vasopressin is constriction of the splanchnic blood flow. Continuous electrocardiogram and blood pressure monitoring are essential because of the constrictive effects of the medication on the coronary arteries. Options 2, 3, and 4 are not essential items required during the administration of this medication.
