Certified Gastroenterology RN Patient Assessment and Education 5 — Questions and Answers
Question 1: A patient scheduled for a colonoscopy at 8 AM asks when to finish the second dose of split-dose bowel prep. The best answer is:
- Complete it 4 to 6 hours before the procedure, per facility protocol (Correct answer)
- Finish it immediately before leaving home
- Take the entire prep two days early to be safe
- Skip the second dose if stools are already brown
Correct answer: Complete it 4 to 6 hours before the procedure, per facility protocol
Split-dose prep finished 4-6 hours pre-procedure optimizes cleansing quality while meeting sedation fasting requirements.
Question 2: Which assessment finding suggests a patient's bowel prep is adequate for colonoscopy?
- Stool effluent is clear or light yellow liquid without solid matter (Correct answer)
- Stools remain brown but are soft
- The patient has had two formed bowel movements
- The patient reports feeling hungry
Correct answer: Stool effluent is clear or light yellow liquid without solid matter
Clear or light yellow liquid output without particulate matter indicates adequate colonic cleansing.
Question 3: The nurse uses the teach-back method after ostomy education. Which patient action best demonstrates learning?
- The patient correctly demonstrates emptying and changing the pouch while explaining each step (Correct answer)
- The patient nods and says the instructions were clear
- The patient accepts written pamphlets to read later
- The patient's spouse states they will handle all ostomy care
Correct answer: The patient correctly demonstrates emptying and changing the pouch while explaining each step
Return demonstration with explanation confirms both psychomotor skill and comprehension better than verbal acknowledgment.
Question 4: A patient with GERD reports symptoms worsen at night. Which lifestyle instruction is most appropriate?
- Elevate the head of the bed 6 to 8 inches and avoid eating within 3 hours of bedtime (Correct answer)
- Sleep flat on the right side after a bedtime snack
- Drink carbonated beverages with dinner to aid digestion
- Wear a tight abdominal binder while sleeping
Correct answer: Elevate the head of the bed 6 to 8 inches and avoid eating within 3 hours of bedtime
Head-of-bed elevation and avoiding late meals reduce nocturnal reflux by using gravity and minimizing gastric contents.
Question 5: When assessing a patient for dehydration after two days of severe vomiting and diarrhea, which finding is most concerning?
- Orthostatic hypotension with tachycardia and minimal urine output (Correct answer)
- Moist mucous membranes with normal skin turgor
- Blood pressure of 118/76 mmHg lying and standing
- Urine output of 60 mL per hour with pale yellow color
Correct answer: Orthostatic hypotension with tachycardia and minimal urine output
Orthostatic hypotension, tachycardia, and oliguria indicate significant volume depletion requiring prompt intervention.
Question 6: A patient beginning pancreatic enzyme replacement therapy (PERT) needs which key teaching point?
- Take the enzymes with every meal and snack (Correct answer)
- Take the enzymes once daily at bedtime on an empty stomach
- Chew the capsules thoroughly before swallowing
- Stop the enzymes once stools become normal
Correct answer: Take the enzymes with every meal and snack
PERT must accompany all food intake so the enzymes can aid digestion; capsules should be swallowed whole, not chewed.
Question 7: The nurse is obtaining a history from a patient with suspected lactose intolerance. Which symptom pattern supports this diagnosis?
- Bloating, cramping, and diarrhea within 30 minutes to 2 hours after consuming dairy (Correct answer)
- Bloody stools and nocturnal diarrhea unrelated to meals
- Heartburn immediately upon lying down after any meal
- Constipation that worsens with increased fluid intake
Correct answer: Bloating, cramping, and diarrhea within 30 minutes to 2 hours after consuming dairy
Undigested lactose ferments in the colon, causing gas, bloating, cramps, and osmotic diarrhea shortly after dairy intake.
