A client who has been taking antibiotics reports severe, watery diarrhea. About which test does the nurse teach the client?
- A. Colonoscopy.
- B. Enzyme-linked immunosorbent assay (ELISA) toxin A+B
- C. Ova and parasites
- D. Stool culture
Correct Answer: B
Rationale: Severe, watery diarrhea after antibiotic use may indicate Clostridioides difficile infection. The ELISA toxin A+B test is used to detect toxins produced by C. difficile. A colonoscopy, ova and parasites test, or stool culture are not typically warranted for this scenario unless further evaluation is needed.

A client presents to the emergency department reporting severe abdominal pain. On assessment, the nurse finds a bulging, pulsating mass in the abdomen. What action by the nurse is the priority?
- A. Auscultate the abdomen.
- B. Notify the provider immediately.
- C. Order an abdominal flat-plate x-ray.
- D. Palpate the abdomen to assess size.
Correct Answer: B
Rationale: The observation could indicate an abdominal aortic aneurysm, which could be life-threatening and should never be palpated. The nurse notifies the provider at once. An x-ray may be indicated, but it is not the priority. Auscultation is part of the assessment, but the nurse's priority action is to notify the provider.
The student nurse studying the gastrointestinal system understands that chyme refers to what?
- A. Hormenization that reduces acidity.
- B. Liquedied food ready for digestion
- C. Nutrients after being absorbed
- D. Secretions that help digest food
Correct Answer: B
Rationale: Before being digested, food must be broken down into a liquid form. This liquid is called chyme. Secretin is the hormone that inhibits acid production and decreases gastric motility. Absorption is carried out so the nutrients produced by digestion move from the lumen of the GI tract into the body's circulatory system for uptake into individual cells. The secretions that help digest food include hydrochloric acid, bile, and digestive enzymes.
The options for colon cancer screening for people over the age of 50 include which of the following? (Select all that apply.)
- A. Colonoscopy every 10 years
- B. CT colonography
- C. Double-contrast barium enema
- D. Flexible sigmoidoscopy every 5 years
- E. Fecal occult blood test annually
Correct Answer: A,C,D
Rationale: Colonoscopy every 10 years, CT colonography, double-contrast barium enema, and flexible sigmoidoscopy every 5 years are standard options for colon cancer screening in people over 50. Fecal occult blood test annually is also a screening option, but it was not listed in the original document and is included here for completeness.
A client is recovering from an esophagealgroduoesoscopy (EGD) and requests something to drink. What action by the nurse is best?
- A. Provide a small sip of water.
- B. Assess the client's gag reflex.
- C. Remind the client to remain NPO.
- D. Tell the client to wait two hours.
Correct Answer: B
Rationale: The local anesthetic used during an EGD can impair the gag reflex. The nurse should assess the client's gag reflex to ensure it is intact before allowing fluids to prevent aspiration. Providing water, reminding the client to remain NPO, or waiting two hours are not appropriate until the gag reflex is confirmed.
A client is scheduled for a colonoscopy and the nurse has provided instructions on the bowel cleansing regimen. What statement by the client indicates a need for further teaching?
- A. Is a good thing I love oranges and cherry gelatin.
- B. My spouse will be here to drive me home.
- C. I should refrigerate the Gol/TELY before use.
- D. I will buy a case of Gonoxide before the prop.
Correct Answer: A
Rationale: The client should be advised to avoid beverages and gelatin that are red, orange, or purple in color as their residue can appear to be blood. The other statements show a good understanding of the preparation for the procedure.
