A nurse is caring for a client with a history of cirrhosis who presents with hematemesis and melena. Endoscopy confirms bleeding esophageal varices. Which nursing intervention should be the priority?

For acute bleeding esophageal varices, priority is preparing for Sengstaken-Blakemore tube insertion to achieve immediate mechanical hemostasis. Other options do not directly control life-threatening hemorrhage.

Understanding the Clinical Scenario
The client with cirrhosis is experiencing an acute episode of hematemesis (vomiting blood) and melena (dark, tarry stools), and endoscopy has confirmed the source is bleeding esophageal varices. This is a life-threatening complication of portal hypertension. The immediate priority is to control the active hemorrhage and prevent hemodynamic collapse.

Analysis of the Priority Intervention
The correct priority nursing intervention is to prepare for insertion of a Sengstaken-Blakemore tube (SBT). While endoscopic variceal ligation is the first-line definitive treatment, the SBT is a critical salvage therapy used to achieve temporary mechanical hemostasis when bleeding is massive and uncontrolled, or when definitive interventions like endoscopy are not immediately available or successful [2,3]. The device works by using an inflated gastric balloon to anchor the tube against the gastroesophageal junction and an esophageal balloon to directly compress the ruptured varices, thereby tamponading the bleeding ^[3]. In a situation where a patient is actively hemorrhaging from confirmed varices, preparing for this temporizing measure is the nurse's immediate focus to stabilize the patient for further procedures.

Why the Other Options are Incorrect
- Option 1: Administering a proton pump inhibitor (PPI) is an adjunctive therapy, not a priority intervention for active variceal hemorrhage. While PPIs may be used after endoscopic treatment to prevent ulcer-related rebleeding, they do not stop the mechanical rupture of a varix and will not control the acute, life-threatening blood loss.
- Option 2: Positioning the client in Trendelenburg position is contraindicated. This position can increase pressure on the esophageal and gastric varices from abdominal contents, potentially worsening the hemorrhage. It also increases intracranial pressure and the risk of aspiration, which is already high due to hematemesis.
- Option 4: Encouraging oral intake of ice chips is an outdated and potentially harmful practice. A patient with active hematemesis and potential for emergent airway management or endoscopic intervention should be kept strictly NPO (nothing by mouth). Ice chips do not provide clinically significant vasoconstriction to stop variceal bleeding and increase the risk of aspiration.

Deep Dive into the Sengstaken-Blakemore Tube
The SBT's role has shifted over time due to the widespread availability of endoscopy and procedures like the transjugular intrahepatic portosystemic shunt (TIPS) [1,3]. However, it remains a high-acuity, low-frequency procedure that is essential for a nurse to understand. Its use is now largely confined to a "bridge" therapy—a temporary measure to control catastrophic bleeding until a more definitive procedure can be performed or the patient can be transferred to a higher level of care [1,2]. Because its use is declining, many providers have limited experience with it, making simulation-based training crucial for maintaining competency in this life-saving intervention [2,4]. The nurse's responsibilities during preparation and insertion include gathering the specialized tube, preparing for balloon inflation, and critically, having scissors at the bedside at all times to cut the tube and rapidly deflate the balloons if they migrate and obstruct the airway. The high risk of complications, such as esophageal rupture or airway obstruction, underscores why this is a temporary salvage technique, not a first-line treatment ^[3].
