Glucagon is sometimes administered during endoscopy procedures primarily to:
Answer: Reduce GI motility temporarily
Glucagon relaxes smooth muscle in the GI tract, temporarily reducing motility to improve visualization and ease instrumentation during some endoscopy procedures.
Simethicone added to irrigation water during endoscopy serves what purpose?
Answer: Reduces foam and bubbles in the GI lumen
Simethicone is an anti-foaming agent that breaks up intraluminal bubbles and foam, significantly improving mucosal visualization during endoscopy.
What is the first-line medication for treating anaphylaxis that occurs during an endoscopy procedure?
Answer: Epinephrine
Epinephrine (adrenaline) is the first-line treatment for anaphylaxis because it reverses bronchospasm, vasodilation, and urticaria through alpha and beta adrenergic stimulation.
Erythromycin administered before emergent upper endoscopy in an upper GI bleed patient is intended to:
Answer: Clear the stomach of blood to improve visualization
Erythromycin acts as a motilin receptor agonist to accelerate gastric emptying, clearing blood and clots to improve visualization at emergent upper endoscopy.
Which medication class may be contraindicated in patients with a known sulfite allergy requiring endoscopy sedation?
Answer: Propofol
Some propofol formulations contain sodium metabisulfite as a preservative, which can trigger reactions in sulfite-sensitive patients.
Atropine is most likely to be used during endoscopy to treat which complication?
Answer: Symptomatic bradycardia
Atropine is the first-line medication for symptomatic bradycardia that may result from a vasovagal response during endoscopy.
