Question 1

During esophageal dilation, the patient develops sudden chest pain, tachycardia, and subcutaneous crepitus. What is the priority nursing action?

Accepted Answer

Stop the procedure and notify the physician of suspected esophageal perforation

Chest pain with crepitus after dilation strongly suggests esophageal perforation, requiring immediate cessation and physician notification.

Question 2

Which patient is at highest risk for post-polypectomy electrocoagulation syndrome during hot snare polypectomy?

Accepted Answer

A patient with a large sessile polyp removed from the thin-walled right colon

Answer

Large sessile lesions in the thin-walled cecum and ascending colon carry the greatest transmural burn risk.

Question 3

A patient develops stridor and facial swelling minutes after IV antibiotic prophylaxis during a GI procedure. After stopping the infusion, which medication is the priority?

Accepted Answer

Intramuscular epinephrine

Answer

Stridor with angioedema indicates anaphylaxis, and epinephrine is the first-line life-saving treatment.

Question 4

During colonoscopy with CO2 insufflation unavailable, prolonged room-air insufflation increases the risk of which intra-procedure problem?

Accepted Answer

Painful luminal distension and vasovagal events from slowly absorbed gas

Answer

Room air absorbs far more slowly than CO2, causing painful distension that can provoke vagal reactions.

Question 5

A patient under propofol sedation for colonoscopy develops rigidity and masseter spasm with a rapidly rising ETCO2 and temperature. The nurse should anticipate preparing which drug?

Accepted Answer

Dantrolene

Answer

Rising ETCO2, rigidity, and hyperthermia suggest malignant hyperthermia, treated with dantrolene.
