A bariatric patient presents with sudden-onset severe periumbilical pain and nausea 18 months post-gastric bypass. The nurse's HIGHEST suspicion should be:
Answer: Internal hernia
Internal hernia is a serious late complication of Roux-en-Y gastric bypass that presents with intermittent or sudden periumbilical pain due to bowel herniation through mesenteric defects.
Thiamine (Vitamin B1) deficiency after bariatric surgery most commonly presents as:
Answer: Wernicke's encephalopathy with confusion, ophthalmoplegia, and ataxia
Severe thiamine deficiency after bariatric surgery can lead to Wernicke's encephalopathy, characterized by the classic triad of confusion, ophthalmoplegia, and ataxia.
Which medication should be AVOIDED after bariatric surgery due to risk of anastomotic ulceration?
Answer: NSAIDs (non-steroidal anti-inflammatory drugs)
NSAIDs are contraindicated after bariatric surgery because they inhibit prostaglandin synthesis, impairing mucosal protection and increasing anastomotic ulcer risk.
A bariatric nurse is assessing a patient for dehydration one week post-surgery. The MOST reliable early indicator is:
Answer: Orthostatic hypotension (drop ≥20 mmHg systolic on standing)
Orthostatic hypotension is an early, clinically significant indicator of dehydration in postoperative bariatric patients who are at high risk due to restricted fluid intake.
A patient reports hair loss (telogen effluvium) 3–4 months after bariatric surgery. The nurse CORRECTLY explains:
Answer: This is a temporary stress response to rapid weight loss and typically resolves within 6–12 months with adequate protein intake
Telogen effluvium after bariatric surgery is a self-limiting condition triggered by physiological stress and protein deficiency, typically resolving within 6–12 months with adequate protein intake.
Which of the following is the correct order for postoperative bariatric diet progression?
Answer: Clear liquids → full liquids → pureed foods → soft foods → regular foods
The standard postoperative bariatric diet progression moves from clear liquids to full liquids, pureed, soft, then regular foods to protect the surgical anastomosis during healing.
