A client with a bleeding peptic ulcer has undergone successful endoscopic hemostasis and is receiving high-dose IV pantoprazole. Which finding requires immediate action by the nurse?
1A mild headache with an oral temperature of 37.2°C after the infusion begins
2One formed dark stool documented before endoscopy with no stool since the procedure
3Epigastric discomfort rated 2 of 10 that decreases after repositioning
4New hematemesis with a heart rate of 118/min and blood pressure of 86/52 mm Hg✓ Correct answer
Explanation
New hematemesis with tachycardia and hypotension indicates recurrent upper gastrointestinal bleeding and hemodynamic instability. The nurse should activate urgent clinical support, assess airway and circulation, maintain IV access, and prepare for resuscitation and repeat evaluation. High-dose proton pump inhibitor therapy after endoscopic hemostasis reduces rebleeding risk but does not eliminate the need to monitor for recurrent hemorrhage.
Clinical reasoning Pantoprazole stabilizes clot formation by suppressing gastric acid after hemostasis. Recurrent hematemesis plus shock findings signals treatment failure or renewed bleeding, not an expected infusion effect.
Decision rule During post-hemostasis PPI therapy, trend emesis and stool appearance, heart rate, blood pressure, hemoglobin, perfusion, and mental status; escalate at once when bleeding and instability recur.
Scenario 58-year-old male with active upper GI bleed from a peptic ulcer; pantoprazole 80 mg IV bolus → 8 mg/hr continuous IV. Hgb 8.5, ongoing transfusion.
Recurrent upper gastrointestinal bleeding — Renewed hemorrhage after initial control, shown by hematemesis or melena with falling perfusion or hemoglobin.
Endoscopic hemostasis — Endoscopic treatment used to control an actively bleeding lesion or a high-risk bleeding stigma.
Step-down therapy — IV PPI → oral PPI once stable; consider H. pylori testing.
