Gastrointestinal System Nursing Exam Questions Questions
Question 1 of 5
A client who has had gastrectomy is not producing sufficient intrinsic factor. The nurse interprets that the client has lost the ability to absorb cyanocobalamin (vitamin B12) in the
Correct Answer: B
Rationale: Intrinsic factor is produced in the stomach but is used to aid in the absorption of vitamin B12 in the small intestine. Vitamin B12 is not absorbed in the large intestine (options 3 and 4).
Question 2 of 5
The nurse is preparing to discontinue a client's nasogastric tube. The client is positioned properly, and the tube has been flushed with 15 mL of air to clear secretions. Before removing the tube, the nurse makes which statement to the client?
Correct Answer: C
Rationale: The client should take a deep breath because the client's airway will be obstructed temporarily during tube removal. The nurse then tells the client to exhale slowly and withdraws the tube during exhalation. Bearing down could inhibit the removal of the tube. Breathing normally could result in aspiration of gastric secretions during inhalation. Holding the breath does not facilitate tube removal.
Question 3 of 5
The client with a colostomy has an order for irrigation of the colostomy. The nurse uses which solution for the irrigation?
Correct Answer: B
Rationale: The correct solution to use for the irrigation of a colostomy is warm tap water or saline solution. If tap water is not suitable for drinking, bottled water can be used. Distilled water, sterile water, and Lactated Ringer's are not appropriate solutions for colostomy irrigation. Distilled water lacks essential minerals, sterile water may not provide adequate cleaning, and Lactated Ringer's is not indicated for this procedure.
Question 4 of 5
Which of the following activities should the nurse encourage the client with a peptic ulcer to avoid?
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.
Question 5 of 5
The nurse is caring for a client following a Billroth II procedure. On review of the postoperative orders, which of the following if prescribed, should the nurse question and verify?
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.
