When should bariatric patients take calcium and iron supplements relative to each other?
Answer: At least 2 hours apart from each other
Calcium and iron compete for the same absorptive transporters and should be taken at least 2 hours apart to optimize absorption of both supplements.
A post-sleeve gastrectomy patient reports worsening gastroesophageal reflux disease (GERD). Which medication is most appropriate for first-line pharmacological management?
Answer: Proton pump inhibitor (e.g., omeprazole)
Proton pump inhibitors provide the most effective and sustained acid suppression and are first-line treatment for GERD after bariatric surgery.
Which antidepressant formulation may have significantly unpredictable bioavailability after gastric bypass and should be avoided?
Answer: SSRIs in extended-release formulations
Extended-release SSRI formulations depend on intact GI anatomy for proper drug release; immediate-release or liquid forms are preferred after gastric bypass.
Severe thiamine (Vitamin B1) deficiency following bariatric surgery can lead to which life-threatening neurological emergency?
Answer: Wernicke encephalopathy
Severe thiamine deficiency can cause Wernicke encephalopathy, presenting with the classic triad of ophthalmoplegia, ataxia, and confusion.
A bariatric patient requires immunosuppressant therapy. What is the most important pharmacological consideration the nurse should communicate?
Answer: Drug levels require more frequent monitoring due to unpredictable GI absorption
Altered GI anatomy after bariatric surgery unpredictably affects immunosuppressant absorption, requiring more frequent therapeutic drug level monitoring.
Which form of vitamin D supplementation is preferred for bariatric patients due to superior potency and bioavailability?
Answer: Vitamin D3 (cholecalciferol) due to superior potency and absorption
Vitamin D3 (cholecalciferol) is preferred in bariatric patients as clinical evidence shows it raises and maintains serum 25(OH)D levels more effectively than D2.
A bariatric patient reports difficulty swallowing her daily multivitamin tablet. What is the most appropriate nursing recommendation?
Answer: Switch to a chewable or liquid multivitamin formulation
Chewable or liquid multivitamins are recommended after bariatric surgery to ensure adequate absorption and improve patient adherence.
