Question 1

Proton pump inhibitors (PPIs) are commonly prescribed after bariatric surgery primarily to:

Accepted Answer

Prevent marginal ulcers at the gastrojejunal anastomosis

Answer

PPIs suppress gastric acid production and are prescribed after bariatric surgery to prevent the formation of marginal ulcers at the anastomotic site.

Question 2

A post-gastric bypass patient taking levothyroxine develops new hypothyroid symptoms. The bariatric nurse should suspect:

Accepted Answer

Impaired levothyroxine absorption due to reduced gastric acid and altered GI anatomy

Answer

Levothyroxine absorption depends on gastric acid and intact absorptive surface; both are altered after gastric bypass, potentially reducing drug efficacy.

Question 3

Which pain management option is most appropriate for a post-bariatric patient requiring non-opioid analgesia?

Accepted Answer

Acetaminophen per protocol

Answer

Acetaminophen is the preferred non-opioid analgesic in bariatric patients; NSAIDs (ibuprofen, naproxen, aspirin) are contraindicated due to anastomotic ulcer risk.

Question 4

After Roux-en-Y gastric bypass, alcohol metabolism is altered in which important way?

Accepted Answer

Peak blood alcohol concentration is higher and reached more quickly

Answer

Reduced gastric alcohol dehydrogenase activity and rapid gastric emptying cause faster and higher peak blood alcohol concentrations after RYGB.

Question 5

What is the minimum recommended daily dose of elemental iron for most bariatric surgical patients to prevent iron deficiency?

Accepted Answer

45–60 mg/day of elemental iron

Answer

Bariatric patients require 45–60 mg/day of elemental iron because reduced gastric acid and bypassed absorptive segments significantly decrease iron absorption efficiency.
