Which of the following best describes the anatomic and absorptive differences between Roux-en-Y gastric bypass and laparoscopic adjustable gastric banding?

A. Roux-en-Y bypasses the duodenum and proximal jejunum, leading to malabsorption of iron and calcium, while lap banding preserves normal GI anatomy and absorption
B. Both procedures remove a portion of the small intestine, leading to similar risks of nutrient malabsorption
C. Lap banding limits absorption by delaying gastric emptying and bypassing the pylorus
D. Roux-en-Y only restricts stomach volume and has minimal impact on nutrient absorption

A. Roux-en-Y bypasses the duodenum and proximal jejunum, leading to malabsorption of iron and calcium, while lap banding preserves normal GI anatomy and absorption

Which medication is commonly used as an induction agent for intubation?

A. Ketorolac

B. Succinylcholine

C. Etomidate

D. Atropine

C. Etomidate

💡 Explanation:

Etomidate is a sedative-hypnotic induction agent used during rapid sequence intubation (RSI):

Onset: 30–60 seconds

Duration: 5–10 minutes

Hemodynamically stable (little effect on BP or HR)

Often used in critically ill or unstable patients

❌ Incorrect Answers:

A. Ketorolac – NSAID for pain; not used in intubation.

B. Succinylcholine – Paralytic agent, not an induction/sedative. Often used after giving etomidate.

D. Atropine – Anticholinergic; may be used in pediatric intubation to prevent bradycardia, but not an induction agent.

Which paralytic is used during rapid sequence intubation (RSI)?

A. Etomidate

B. Propofol

C. Succinylcholine

D. Fentanyl

C. Succinylcholine
