Gastrointestinal System Nursing Exam Questions

Correct Answer: D

Rationale: For the first 4 to 6 weeks following colostomy formation, the client should take in a low-residue diet. Following this period, the client should eat a high-carbohydrate, high-protein diet. The nurse also instructs the client to add new foods, one at a time, to determine tolerance to that food.

Correct Answer: B

Rationale: Cholestyramine resin binds with bile salts in the intestines to form a compound that is excreted in the feces. The client should be instructed to mix the medication with 3 to 6 oz of water, milk, fruit juice, or soup. The medication should be administered before meals. The medication is not administered via rectal suppository.

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.

Correct Answer: C

Rationale: The correct answer is C: Turnips. The nurse would instruct the client to avoid red meat, poultry, fish, turnips, horseradish, and foods such as fruits and vegetables for 3 days before and during testing. These products may alter test results. Choices A, B, and D are incorrect because they are not specifically mentioned as items to avoid before collecting a stool specimen for occult blood.

Correct Answer: B

Rationale: Foods that increase the lower esophageal sphincter (LES) pressure will decrease reflux, and lessen the symptoms of gastroesophageal reflux disease (GERD). The food substance that will increase the LES pressure is nonfat milk. The other substances listed decrease the LES pressure, thus increasing reflux symptoms. Aggravating substances include chocolate, coffee, fatty foods and alcohol.
