Chapter 44 : Introduction to the Gastrointestinal System and Accessory Structures Questions
Question 1 of 5
Which nursing instruction is correct to provide the client following a barium enema?
Correct Answer: B
Rationale: It is important to instruct the client that it is normal to have a white- or clay-colored stool following the barium enema. The client should report the color of the stool to the nurse. A progression of clay-colored stools to brown-colored stools should be noted. The client is prescribed a low-residue diet before the procedure. An increased fluid intake is offered to eliminate the barium from the bowel. The client is encouraged to move the bowel independently.
Question 2 of 5
The nurse is scheduling gastrointestinal (GI) diagnostic testing for a client. Which GI test should be scheduled first?
Correct Answer: A
Rationale: Radiography of the gallbladder should be performed before the other GI exams listed in which barium is used because residual barium tends to obscure the images of the gallbladder and its duct.
Question 3 of 5
The nurse is caring for a client who is scheduled for a percutaneous liver biopsy. Which diagnostic test is obtained prior?
Correct Answer: B
Rationale: The client must have coagulation studies (PT, aPTT, INR, platelet count) before the procedure because a major complication after a liver biopsy is bleeding. Clients at risk for serious bleeding may receive precautionary vitamin K. A complete blood count and blood chemistry may be completed for baseline values. Typically, an ESR is not associated with the procedure.
Question 4 of 5
The nurse is instructing a client prior to a colonoscopy. The client asks, 'Why do I have to drink this disgusting liquid?' The nurse is most correct to verbalize the goal of the oral preparation as which of the following?
Correct Answer: C
Rationale: The goal of the oral preparation is to eliminate fecal matter to visualize the colon structures. Having a clean colon free of fecal matter does allow for ease of passage of the scope and eliminates gas. The client is sedated throughout the procedure so does not experience pain.
Question 5 of 5
The nurse is working in a diagnostic testing unit focusing on gastrointestinal studies. For which testing procedure is the nurse correct to assess the gag reflex before offering fluids?
Correct Answer: A
Rationale: The nurse is correct to assess the gag reflex prior to offering fluids for a client having an esophagogastroduodenoscopy (EG
D). The other options are lower gastrointestinal studies typically requiring a bowel preparation.
