Gastrointestinal System Nursing Exam Questions

Correct Answer: C

Rationale: Early manifestations of dumping syndrome occur 5 to 30 minutes after eating. Symptoms include vertigo, tachycardia, syncope, sweating, pallor, palpitations, and the desire to lie down.

Correct Answer: B

Rationale: During the insertion of a nasogastric tube, if the client experiences difficulty breathing or any respiratory distress, withdraw the tube slightly, stop the tube advancement, and wait until the distress subsides. Options 1 and 4 are unnecessary. Quickly inserting the tube is not an appropriate action because, in this situation, it may be likely that the tube has entered the bronchus.

Correct Answer: C

Rationale: Hematocrit is the best indicator of hydration status because it reflects the proportion of red blood cells in the blood. An increased hematocrit indicates dehydration, as the blood becomes more concentrated due to fluid loss. Erythrocyte sedimentation rate (Choice A) is a nonspecific marker of inflammation, not hydration status. White blood cell count (Choice B) is an indicator of infection or inflammation. Serum glucose (Choice D) is used to monitor blood sugar levels, not hydration status.

Correct Answer: A

Rationale: In a Billroth II procedure the proximal remnant of the stomach is anastomosed to the proximal jejunum. Patency of the nasogastric tube is critical for preventing the retention of gastric secretions. The nurse should never irrigate or reposition the gastric tube after gastric surgery, unless specifically ordered by the physician. In this situation the nurse should clarify the order. Coughing and deep breathing exercises, leg exercises, and early ambulation are appropriate postoperative interventions.

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.
