A nurse is reinforcing teaching with a client who is scheduled to have a colonoscopy in 1 week. Which of the following client statements indicates an understanding of the teaching?
"I will follow a full-liquid diet the day before the procedure."
"I'll have my friend drive me home after the procedure."
"I can expect rectal bleeding for a week after the procedure”
"This procedure will take place while I’m under general anesthesia.”
The Correct Answer is B
Rationale:
A. "I will follow a full-liquid diet the day before the procedure.": Clients are typically instructed to follow a clear-liquid, not full-liquid, diet the day before a colonoscopy. Clear liquids like broth, gelatin, and clear juice help ensure the colon is clean for optimal visualization.
B. "I'll have my friend drive me home after the procedure.": Sedation is usually administered during a colonoscopy, which impairs alertness and coordination. Having a responsible adult to drive the client home is necessary and reflects appropriate understanding of post-procedure safety.
C. "I can expect rectal bleeding for a week after the procedure”: Rectal bleeding after a colonoscopy is not expected and could indicate complications such as a perforation or polyp removal site bleeding. Any persistent or heavy bleeding should be reported immediately.
D. "This procedure will take place while I’m under general anesthesia.”: Colonoscopies are generally performed under moderate (conscious) sedation, not general anesthesia. Clients remain semi-awake but relaxed and unaware, making this statement inaccurate.

Correct Answer is ["31"]
Explanation
Calculation:
Total volume to be infused = 500 mL.
- Convert the infusion time from hours to minutes.
Infusion time = 4 hr × 60 min/hr
= 240 min.
Drop factor = 15 gtt/mL.
- Calculate the flow rate in drops per minute (gtt/min).
Flow rate (gtt/min) = (Total volume (mL) × Drop factor (gtt/mL)) / Infusion time (min)
= (500 mL × 15 gtt/mL) / 240 min
= 7500 gtt / 240 min
= 31.25 gtt/min.
Rounded to the nearest whole number:
= 31 gtt/min.
Correct Answer is C
Explanation
Rationale:
A. Milk: Milk does not interfere with fecal occult blood testing and does not contain substances that cause false-positive results. It can be safely consumed prior to the test without affecting the accuracy of the results.
B. Whole wheat bread: Whole wheat bread is high in fiber, which is actually beneficial when preparing for a fecal occult blood test. It helps promote regular bowel movements but does not lead to false-positive results.
C. Red meat: Red meat contains heme, a form of animal blood, which can cause false-positive results on guaiac-based fecal occult blood tests. Avoiding red meat for at least 3 days prior to the test helps reduce the risk of inaccurate results.
D. Almonds: Almonds and other nuts do not contain components that interfere with fecal occult blood testing. They are not known to cause false-positive or false-negative results and are safe to consume before the test.
