Nokea
The nurse is caring for a client following a colonoscopy. During the procedure, two medium-sized polyps were removed. Which nursing assessment in the recovery area is a priority?
- A. Assessment of level of consciousness
- B. Hemoccult test of stool
- C. Vital signs
- D. Ability to tolerate liquids
Correct Answer: C
Rationale: The nurse is correct in assessing vital signs following a colonoscopy with polyp removal as a priority. Vital signs of an increased pulse rate and falling blood pressure can indicate a perforation and bleeding. If a perforation occurs and is not addressed at an early stage, the client's level of consciousness can become affected. There would be no reliable stool present in the bowel to Hemoccult test due to the cleansing agent and potential bleeding from the polyp removal. The ability to tolerate fluids relates to the sedation process and is not as high of a priority.

- B. To decrease pain associated with fecal matter being pressed against the colon wall
- C. To cleanse the bowel to promote clear visualization of structures
- D. To eliminate gas from the internal portion of the colon

The nurse is instructing the client who was newly diagnosed with peptic ulcers. Which of the following diagnostic studies would the nurse anticipate reviewing with the client?
- A. A complete blood count including differential
- B. Serum antibodies for H. pylori
- C. A sigmoidoscopy
- D. Gastric analysis
Correct Answer: B
Rationale: Helicobacter pylori, a bacterium, is believed to be responsible for the majority of peptic ulcers. Blood tests are used to determine whether there are antibodies to H. pylori in the blood. A complete blood count with differential can indicate bleeding and infection associated with a bleeding ulcer. A sigmoidoscopy assesses the lower gastrointestinal tract. Gastric analysis is more common in analyzing gastric fluid in determining problems with the secretory activity of the gastric mucosa.
