While making rounds on a medical-surgical unit, a nurse discovers that a client with a history of peptic ulcer disease is suddenly vomiting a large volume of bright red blood and appears extremely pale and diaphoretic. To prevent life-threatening hemodynamic collapse, which nursing action takes immediate priority?

해설
Establishing large-bore IV access is the immediate priority for acute variceal bleeding to enable rapid fluid resuscitation and prevent hemodynamic collapse. Lactulose and NG tube are secondary. Endoscopic band ligation is done after stabilization.

Core Nursing Explanation Key Concept Analysis: This question tests the nurse's ability to prioritize immediate, life-saving interventions for a patient experiencing an Acute Upper Gastrointestinal (GI) Bleed. The scenario describes a patient with a history of peptic ulcer disease (PUD) who is actively vomiting bright red blood (hematemesis), a sign of a significant arterial bleed. The patient's pallor and diaphoresis (sweating) are classic signs of Hypovolemic Shock due to massive blood loss. The priority is to prevent hemodynamic collapse by restoring intravascular volume.

Answer Rationale: Key Point! In any emergency situation, the nursing process begins with the ABCs (Airway, Breathing, Circulation). While the airway is patent (the patient is vomiting), the immediate threat is to circulation. Establishing large-bore IV access (two 18-gauge or larger IV lines) is the first and most critical nursing action to enable rapid infusion of IV fluids, blood products, and medications to support blood pressure and organ perfusion. This action directly addresses the risk of hypovolemic shock and buys time for definitive diagnostic and therapeutic procedures.

Distractor Analysis:
Watch out for confusion! Option 1: Administer prescribed lactulose. Lactulose is used to treat Hepatic Encephalopathy associated with Esophageal Varices in liver disease, not for acute bleeding from a peptic ulcer. It is not a priority for hemodynamic stabilization.
Option 2: Insert a nasogastric (NG) tube. While an NG tube may be inserted to assess the rate of bleeding, lavage the stomach, or prepare for endoscopy, it is not the immediate priority over securing IV access. In some cases of severe variceal bleeding, NG tube insertion is contraindicated due to the risk of worsening the bleed.
Option 4: Prepare the patient for endoscopic band ligation. Endoscopic procedures like band ligation (for varices) or cautery/injection (for ulcers) are the definitive treatments to stop the bleeding. However, the patient must be hemodynamically stabilized first before undergoing any procedure. You cannot safely transport or sedate a patient in active hypovolemic shock.

Related Concepts: The management of acute GI bleed follows a clear sequence: Resuscitate (IV access, fluids, blood) → Diagnose (endoscopy) → Treat (endoscopic therapy, surgery). Nursing priorities align with this sequence, focusing first on supporting the patient's vital functions. Concept Summary
ConceptDescriptionNursing Implication
Hypovolemic ShockLife-threatening condition from loss of blood/fluid volume, leading to inadequate tissue perfusion.Priority is rapid IV fluid/blood replacement. Monitor for tachycardia, hypotension, cool/clammy skin, decreased urine output.
Peptic Ulcer Disease (PUD)Erosion in the stomach or duodenal lining, a common cause of upper GI bleed.Bleeding can be arterial and massive. Management includes acid suppression (PPIs), endoscopic therapy, and treating H. pylori.
HematemesisVomiting of bright red blood, indicating active, often arterial, upper GI bleeding.A medical emergency. Assess amount, color, and patient's hemodynamic status immediately.
Large-Bore IV AccessUsing 14-18 gauge IV catheters to allow rapid infusion of fluids and blood products.Essential first step in managing any major hemorrhage. Two IV lines are often required.
Side-by-Side Comparison!
InterventionPurpose & TimingWhy It's Not the *Immediate* Priority in This Scenario
Establish IV AccessTo resuscitate and prevent shock. FIRST priority.N/A - This is the correct, immediate action.
Insert NG TubeTo assess bleeding, lavage, or decompress. Done after or while starting resuscitation.Does not directly treat hypovolemia. Can be delayed by minutes needed to start IV fluids.
Prepare for EndoscopyDefinitive diagnosis and treatment. Done after patient is stabilized.Requires a stable patient for safe sedation and procedure. Putting the cart before the horse.
Administer LactuloseTo reduce ammonia in liver failure patients with variceal bleed. A secondary treatment.The patient has PUD, not confirmed liver disease/varices. Does not address the circulatory crisis.
Anatomy, Physiology & Pharmacology Points
  • Pathophysiology: A bleeding peptic ulcer erodes into an artery in the stomach or duodenal wall. Rapid blood loss → decreased circulating volume → decreased venous return to the heart → decreased cardiac output → hypotension and shock.
  • Pharmacology: Initial IV fluids are crystalloids (e.g., Normal Saline, Lactated Ringer's). Packed Red Blood Cells (PRBCs) are given for significant blood loss. Proton Pump Inhibitors (PPIs) like pantoprazole IV are given to reduce gastric acid and promote clot stability.
Memory Tips
  • ABCs for GI Bleed: Think "Access (IV) before Bag (blood) before Camera (endoscopy)."
  • Shock Signs: Remember the "3 Cs" of hypovolemic shock: Cool/Clammy skin, Confusion, Collapsed veins.
High-Frequency NCLEX Topics NCLEX loves testing prioritization and emergency response. Acute GI bleed is a classic scenario. Always ask yourself: "What will kill the patient first?" Loss of circulation (bleeding) kills faster than the specific cause of the bleed. Securing the "plumbing" (IV access) to replace lost volume is almost always the first nursing action. Watch Out for Question Variations!
  • Instead of "What is the priority action?", it could be: "The nurse is preparing to administer a blood transfusion to a patient with GI bleed. Which action should the nurse take first?" (Answer: Ensure two patent IV lines are established—one for the blood, one for other fluids/meds).
  • The patient condition could change: "After establishing two large-bore IVs and initiating fluid resuscitation, the patient's blood pressure remains low. What is the nurse's next priority?" (Answer: Initiate transfusion of packed red blood cells as prescribed).

임상 시나리오

Nursing Clinical Practice Guide Clinical Scenario: You are the nurse on a med-surg floor. Your patient, Mr. Jones, 58, with a history of PUD and NSAID use, calls you to the room. He is vomiting into an emesis basin filled with bright red liquid. He is pale, sweating profusely, and says he feels dizzy and weak.

Nursing Intervention Strategy:
  1. Immediate Action (Seconds): Call for help (activate rapid response/code if needed) while staying with the patient. Simultaneously assess ABCs. Position the patient to prevent aspiration (side-lying if alert).
  2. Priority Intervention (1-2 Minutes): Establish IV access. If no IV is present, insert two large-bore (16-18g) IV catheters in large veins (e.g., antecubital). If an IV is present but is small (e.g., 22g), it is not adequate for rapid resuscitation. Start a new, large-bore line.
  3. Concurrent Actions:
    • Apply oxygen via nasal cannula.
    • Obtain vital signs (expect tachycardia >100 and hypotension
