Proton pump inhibitors (PPIs) are commonly prescribed after bariatric surgery primarily to:
Answer: Prevent marginal ulcers at the gastrojejunal anastomosis
PPIs suppress gastric acid production and are prescribed after bariatric surgery to prevent the formation of marginal ulcers at the anastomotic site.
A post-gastric bypass patient taking levothyroxine develops new hypothyroid symptoms. The bariatric nurse should suspect:
Answer: Impaired levothyroxine absorption due to reduced gastric acid and altered GI anatomy
Levothyroxine absorption depends on gastric acid and intact absorptive surface; both are altered after gastric bypass, potentially reducing drug efficacy.
Which pain management option is most appropriate for a post-bariatric patient requiring non-opioid analgesia?
Answer: Acetaminophen per protocol
Acetaminophen is the preferred non-opioid analgesic in bariatric patients; NSAIDs (ibuprofen, naproxen, aspirin) are contraindicated due to anastomotic ulcer risk.
After Roux-en-Y gastric bypass, alcohol metabolism is altered in which important way?
Answer: Peak blood alcohol concentration is higher and reached more quickly
Reduced gastric alcohol dehydrogenase activity and rapid gastric emptying cause faster and higher peak blood alcohol concentrations after RYGB.
What is the minimum recommended daily dose of elemental iron for most bariatric surgical patients to prevent iron deficiency?
Answer: 45–60 mg/day of elemental iron
Bariatric patients require 45–60 mg/day of elemental iron because reduced gastric acid and bypassed absorptive segments significantly decrease iron absorption efficiency.
Bypass of the duodenum and proximal jejunum in RYGB surgery places patients at highest risk for deficiency of which mineral?
Answer: Iron
The duodenum and proximal jejunum are the primary sites of dietary iron absorption, so bypassing them in RYGB dramatically increases the risk of iron deficiency.
A bariatric patient on warfarin therapy requires closer INR monitoring post-surgery because:
Answer: Altered fat and vitamin K absorption can cause unpredictable INR fluctuations
Changes in fat-soluble vitamin K absorption after bariatric surgery cause unpredictable INR changes, requiring more frequent anticoagulation monitoring.
