A nurse is caring for a client who was admitted with bleeding esophageal varices and has an esophagogastric balloon tamponade with a Sengstaken-Blakemore tube to control the bleeding. Which of the following actions should the nurse take?

Managing esophagogastric balloon tamponade requires knowledge of airway protection and mucosal integrity. Applying nursing interventions for a client with a Sengstaken-Blakemore tube involves preventing complications like aspiration and tissue necrosis while maintaining the mechanical pressure needed for hemostasis. Choice A rationale Frequent oral and nares care is essential because the tube causes irritation and prevents the client from swallowing saliva. Secretions accumulate in the upper airway, increasing infection risk and skin breakdown at the insertion site. Choice B rationale Clients with a Sengstaken-Blakemore tube must remain strictly NPO to prevent aspiration and avoid disturbing the tube. The balloon occupies the esophagus and stomach to stop variceal bleeding, making oral intake impossible and extremely dangerous. Choice C rationale Ambulation is contraindicated for a client with an active balloon tamponade due to the risk of tube displacement. Displacement can lead to airway obstruction if the gastric balloon migrates upward into the oropharynx or trachea. Choice D rationale A supine position increases the risk of aspiration and respiratory distress. The nurse should maintain the head of the bed at 30 to 45 degrees to facilitate breathing and minimize the risk of pulmonary complications.
