Question 1

A patient scheduled for colonoscopy reports taking clopidogrel daily after cardiac stent placement 2 months ago. What is the gastroenterology nurse's best action?

Accepted Answer

Notify the provider so the cardiology and GI teams can weigh bleeding vs. thrombosis risk

Answer

Antiplatelet management after recent stenting requires coordinated provider decision-making because stopping clopidogrel risks stent thrombosis.

Question 2

During moderate sedation with midazolam and fentanyl, a patient's respiratory rate drops to 6 breaths/min with SpO2 of 84%. After stimulating the patient and giving oxygen, which reversal agent addresses the opioid component?

Accepted Answer

Naloxone

Answer

Naloxone reverses opioid-induced respiratory depression, while flumazenil reverses benzodiazepines.

Question 3

A patient with cirrhosis presents with hematemesis. Which finding most strongly suggests bleeding esophageal varices rather than peptic ulcer disease?

Accepted Answer

Splenomegaly and ascites on exam

Answer

Splenomegaly and ascites indicate portal hypertension, the underlying cause of esophageal varices.

Question 4

What is the primary purpose of split-dose bowel preparation before colonoscopy?

Accepted Answer

To improve mucosal visualization and adenoma detection

Answer

Split-dose prep produces superior colon cleansing, which directly improves adenoma detection rates.

Question 5

A patient develops severe abdominal pain, fever, and abdominal rigidity 4 hours after a therapeutic colonoscopy with polypectomy. The nurse should suspect which complication?

Accepted Answer

Bowel perforation with peritonitis

Answer

Rigidity with fever and severe pain after polypectomy indicates perforation and peritonitis, a surgical emergency.
