Certified Gastroenterology RN Pre and Post-Procedure Care 2 — Questions and Answers
Question 1: A patient scheduled for colonoscopy at 10 AM asks when to take the second half of a split-dose bowel prep. What should the nurse advise?
- Complete it 4-6 hours before the procedure (Correct answer)
- Take it immediately before leaving home
- Skip it if stools are already clear
- Take both doses the evening before
Correct answer: Complete it 4-6 hours before the procedure
Split-dose prep is most effective when the second dose is finished 4-6 hours before the procedure, improving mucosal visualization.
Question 2: Before an EGD with moderate sedation, which patient statement requires the nurse to notify the provider?
- "I had a glass of water 2 hours ago"
- "I ate a full breakfast an hour ago" (Correct answer)
- "I took my blood pressure pill with a sip of water"
- "I stopped my fish oil last week"
Correct answer: "I ate a full breakfast an hour ago"
A recent full meal violates fasting guidelines and creates a significant aspiration risk during sedation.
Question 3: A patient on warfarin is scheduled for polypectomy. The nurse should verify that which action was taken?
- Warfarin was doubled to prevent clots
- Anticoagulation management was addressed per provider orders (Correct answer)
- Aspirin was substituted the morning of the procedure
- The patient stopped warfarin 24 hours prior on their own
Correct answer: Anticoagulation management was addressed per provider orders
High-bleeding-risk procedures like polypectomy require a provider-directed anticoagulation plan, often holding warfarin about 5 days with possible bridging.
Question 4: Which finding in the recovery area after colonoscopy with polypectomy most warrants immediate provider notification?
- Mild cramping relieved by passing flatus
- Abdominal distension with rigidity and severe pain (Correct answer)
- One small smear of blood on the first stool
- Drowsiness 20 minutes after sedation
Correct answer: Abdominal distension with rigidity and severe pain
Rigidity, distension, and severe pain suggest perforation, a surgical emergency.
Question 5: What is the primary purpose of the Aldrete score in post-procedure care?
- To assess bowel prep adequacy
- To determine readiness for discharge from recovery after sedation (Correct answer)
- To grade procedural bleeding risk
- To document informed consent completion
Correct answer: To determine readiness for discharge from recovery after sedation
The Aldrete score evaluates activity, respiration, circulation, consciousness, and oxygen saturation to determine recovery from sedation.
Question 6: A patient received midazolam and fentanyl for endoscopy and now has a respiratory rate of 6 with minimal response to stimulation. Which agents should the nurse have available?
- Flumazenil and naloxone (Correct answer)
- Protamine and vitamin K
- Atropine and epinephrine only
- Glucagon and dextrose
Correct answer: Flumazenil and naloxone
Flumazenil reverses benzodiazepines and naloxone reverses opioids, addressing both sedative agents causing respiratory depression.
Question 7: Which discharge instruction is appropriate for a patient who received moderate sedation for an outpatient endoscopy?
- Resume driving once you feel alert
- Do not drive, operate machinery, or sign legal documents for 24 hours (Correct answer)
- Return to work immediately if no pain
- Avoid all oral intake for 12 hours
Correct answer: Do not drive, operate machinery, or sign legal documents for 24 hours
Sedatives impair judgment and reflexes for up to 24 hours, so driving and major decisions must be deferred.
