Question 1

Glucagon is sometimes administered during endoscopy procedures primarily to:

Accepted Answer

Reduce GI motility temporarily

Answer

Glucagon relaxes smooth muscle in the GI tract, temporarily reducing motility to improve visualization and ease instrumentation during some endoscopy procedures.

Question 2

Simethicone added to irrigation water during endoscopy serves what purpose?

Accepted Answer

Reduces foam and bubbles in the GI lumen

Answer

Simethicone is an anti-foaming agent that breaks up intraluminal bubbles and foam, significantly improving mucosal visualization during endoscopy.

Question 3

What is the first-line medication for treating anaphylaxis that occurs during an endoscopy procedure?

Accepted Answer

Epinephrine

Answer

Epinephrine (adrenaline) is the first-line treatment for anaphylaxis because it reverses bronchospasm, vasodilation, and urticaria through alpha and beta adrenergic stimulation.

Question 4

Erythromycin administered before emergent upper endoscopy in an upper GI bleed patient is intended to:

Accepted Answer

Clear the stomach of blood to improve visualization

Answer

Erythromycin acts as a motilin receptor agonist to accelerate gastric emptying, clearing blood and clots to improve visualization at emergent upper endoscopy.

Question 5

Which medication class may be contraindicated in patients with a known sulfite allergy requiring endoscopy sedation?

Accepted Answer

Propofol

Answer

Some propofol formulations contain sodium metabisulfite as a preservative, which can trigger reactions in sulfite-sensitive patients.
