Certified Gastroenterology RN Pre and Post-Procedure Care Questions and Answers

Question 1

A patient with type 2 diabetes, managed with daily long-acting insulin and metformin, is scheduled for an 8:00 AM colonoscopy. Which instruction regarding their diabetes medications is most appropriate for the morning of the procedure?

Accepted Answer

Hold the metformin and consult the prescribing provider for instructions on adjusting the long-acting insulin dose.

Answer

Metformin is typically held for 24-48 hours before a procedure involving potential renal stress or contrast media due to the risk of lactic acidosis. Long-acting insulin doses often need to be reduced (e.g., by 30-50%) to prevent hypoglycemia while the patient is NPO, but this adjustment requires a specific provider order. Therefore, the safest action is to hold the metformin and obtain clear instructions for the insulin dose.

Question 2

A patient is being monitored in the recovery area following an Endoscopic Retrograde Cholangiopancreatography (ERCP). Which of the following assessment findings is the strongest indicator of potential post-ERCP pancreatitis?

Accepted Answer

New onset of severe, persistent mid-epigastric pain that radiates to the back.

Answer

While a sore throat, bloating, and nausea can occur after ERCP, the hallmark symptom of post-ERCP pancreatitis, the most common serious complication, is new or worsening mid-epigastric or upper abdominal pain that is often severe and radiates to the back. This symptom requires immediate notification of the provider for further evaluation.

Question 3

The gastroenterology nurse is performing a pre-procedure medication reconciliation for a patient scheduled for a colonoscopy with possible polypectomy. Which of the following patient-reported medications requires the MOST urgent clarification with the prescribing provider?

Accepted Answer

Clopidogrel 75 mg daily.

Answer

Clopidogrel is a potent antiplatelet agent that significantly increases the risk of bleeding after a high-risk procedure like polypectomy. Management requires careful coordination between the endoscopist and the prescribing provider to balance the risk of bleeding against the risk of a thromboembolic event. The other medications (thyroid hormone, beta-blocker, calcium channel blocker) are typically continued and do not pose a direct, significant bleeding risk.

Question 4

A patient in the recovery unit two hours after an upper endoscopy (EGD) develops acute chest pain, neck pain, and dysphagia. During assessment, the nurse palpates crepitus in the suprasternal notch. Which action should the nurse take FIRST?

Accepted Answer

Place the patient on NPO status and notify the physician immediately.

Answer

The combination of chest/neck pain, difficulty swallowing (dysphagia), and subcutaneous crepitus (air in the subcutaneous tissue) are hallmark signs of an esophageal perforation, a life-threatening emergency. The immediate priority is to make the patient NPO to prevent further contamination of the mediastinum and to notify the physician for urgent intervention.

Question 5

A nurse is providing discharge instructions for a patient who underwent a colonoscopy with several large polypectomies. Which instruction is crucial for minimizing the risk of delayed post-polypectomy bleeding?

Accepted Answer

Avoid strenuous activity, heavy lifting, and air travel for 7-14 days as directed by your provider.

Answer

Delayed post-polypectomy bleeding can occur up to 30 days after the procedure and is often precipitated by activities that increase intra-abdominal pressure, which can dislodge the eschar or clips at the removal site. Instructing the patient to avoid strenuous activity and heavy lifting is a key preventative measure. Diet is usually advanced slowly, and fever is more indicative of post-polypectomy syndrome, not directly preventative of bleeding.
