A client with cirrhosis is admitted with hematemesis and tachycardia. The nurse suspects variceal bleeding. Which action should the nurse take first?

Choice A reason: IV proton pump inhibitors reduce gastric acid, preventing ulcer-related bleeding, but variceal bleeding in cirrhosis results from portal hypertension, not acid-related injury. Hematemesis risks airway aspiration, making airway assessment the priority. Proton pump inhibitors are supportive but not the first action in acute variceal bleeding with potential airway compromise. Choice B reason: Endoscopic band ligation is a definitive treatment for variceal bleeding, occluding bleeding esophageal varices. However, it requires preparation and sedation, delaying intervention. Hematemesis and tachycardia suggest active bleeding, risking airway aspiration. The ABCDE approach prioritizes airway assessment to ensure patency before procedural interventions like endoscopy. Choice C reason: IV vasopressin reduces portal pressure, controlling variceal bleeding, but it acts over time and may cause vasoconstriction-related complications. Hematemesis poses an immediate airway risk due to aspiration. The ABCDE approach prioritizes airway and breathing assessment to prevent respiratory compromise, making vasopressin a secondary intervention in this acute scenario. Choice D reason: Hematemesis in variceal bleeding risks airway aspiration, a life-threatening complication, especially with tachycardia indicating hypovolemia. Assessing airway and breathing ensures patency and adequate oxygenation, critical in the ABCDE approach. This is the first action to prevent respiratory arrest, prioritizing airway protection before addressing bleeding or hemodynamic instability in cirrhosis.
