A nurse is caring for a postoperative patient who suddenly develops signs of shock. Which nursing intervention should be implemented first?
A 45-year-old patient underwent major abdominal surgery 6 hours ago and suddenly develops hypotension (BP 85/50 mmHg), tachycardia (HR 120 bpm), decreased urine output (15 mL/hr), and cool, clammy skin.

2Insert a large-bore IV catheter and prepare for fluid resuscitation
3Obtain vital signs every 15 minutes and notify the physician immediately
4Administer prescribed pain medication to reduce patient anxiety
해설
In shock management, the priority is to optimize tissue perfusion and oxygenation. Positioning and oxygen therapy are immediate interventions that can be implemented without physician orders, addressing the ABCDE approach.
Core Nursing ExplanationKey Concept Analysis: This question tests the nurse's ability to prioritize immediate interventions for a patient in hypovolemic shock, a common postoperative complication. The scenario describes classic signs: hypotension (85/50 mmHg), tachycardia (120 bpm), decreased urine output (15 mL/hr), and cool, clammy skin. The core principle is the ABCDE approach to emergency management, where Airway, Breathing, and Circulation are the absolute priorities.
Answer Rationale: Key Point! The correct answer is 1 because it addresses the first two steps of the ABCDE approach simultaneously. The modified Trendelenburg position (supine with legs elevated 20-30 degrees) promotes venous return to the heart, improving preload and cardiac output to address Circulation. Administering oxygen ensures adequate oxygenation to vital organs, addressing Breathing. These are independent nursing actions that can be initiated immediately while other interventions are being prepared.
Distractor Analysis:
Watch out for confusion! While 2 (Insert IV and prepare for fluids) is a critical and urgent intervention for hypovolemic shock, it is not the first action. Establishing IV access requires equipment and takes time. The actions in option 1 can be done literally within seconds to support the patient's physiology while the IV is being set up.
Watch out for confusion! Option 3 (Obtain vital signs and notify physician) involves assessment and communication, which are essential but are not direct interventions to treat the shock state. The nurse must act first to stabilize the patient, then notify.
Watch out for confusion! Option 4 (Administer pain medication) is contraindicated in this scenario. Administering analgesics, especially opioids, to a hypotensive patient can further lower blood pressure and depress respiratory drive, worsening the shock.
Related Concepts: This integrates knowledge of postoperative complications, shock pathophysiology (inadequate tissue perfusion), and emergency nursing protocols. Understanding the sequence of the nursing process in a crisis—rapid assessment, immediate intervention, then notification and further treatment—is crucial.
Concept Summary
Concept
Description
Hypovolemic Shock
A state of inadequate tissue perfusion due to loss of intravascular volume (e.g., hemorrhage, dehydration).
Positioning with legs elevated, trunk flat. Promotes autotransfusion of blood from legs to core.
Independent Nursing Action
Interventions a nurse can initiate without a physician's order based on clinical judgment.
Side-by-Side Comparison!
Intervention
Priority Rationale
When to Implement
Positioning & O2
Supports Circulation & Breathing (ABC). Immediate, no equipment delay.
FIRST - Within seconds of recognition.
Establish IV Access
Essential for fluid/medication administration to treat cause.
SECOND - Initiated concurrently or immediately after first action.
Notify Physician
Required for orders (fluids, blood, vasopressors).
After or while initiating life-saving measures.
Anatomy, Physiology & Pharmacology Points
The pathophysiology involves a drop in preload (venous return) leading to decreased stroke volume and cardiac output. The body compensates via the sympathetic nervous system (tachycardia, vasoconstriction causing cool skin). The kidneys conserve fluid, leading to oliguria (low urine output). Never give medications that depress the vasomotor center (like some analgesics) in shock.
Memory TipsABCs come before IVs! Remember the order: Airway, Breathing, Circulation. Positioning and oxygen are part of B and C. Also, think: "Do no harm first" – option 4 (pain meds) could cause harm.
High-Frequency NCLEX Topics
Prioritization ("first", "immediate", "priority") and management of shock/hemorrhage are classic NCLEX topics. The exam consistently tests the nurse's ability to apply the ABC framework and distinguish between assessment, notification, and direct intervention.
Watch Out for Question Variations!
The same concept can be tested by: 1) Asking for the next intervention after positioning/O2 (answer: establish large-bore IV access). 2) Changing the patient condition (e.g., anaphylactic shock – priority would be epinephrine). 3) Asking which finding to report first (answer: decreased urine output, as it's an early sign of poor perfusion).Nursing Clinical Practice GuideClinical Scenario: You are the nurse on a surgical floor. Your patient, Mr. Jones, s/p exploratory laparotomy, calls you saying he feels dizzy and weak. You enter and find him pale, anxious, with cool, diaphoretic skin.
Nursing Intervention Strategy:
Immediate Action (Seconds): Call for help. While approaching, assess responsiveness (A). Manually lower the head of the bed to flat, elevate legs if no spinal precautions. Apply a non-rebreather mask at 10-15 L/min for O2.
Rapid Assessment & Intervention (1-2 Minutes): Feel for a carotid pulse, assess rate/rhythm (C). Simultaneously, another nurse obtains a full set of vitals and connects to the monitor. Inspect the surgical dressing and under the patient for frank bleeding.
Treatment Initiation (2-5 Minutes): Insert two large-bore (16- or 18-gauge) IV catheters if not present. Begin a rapid infusion of isotonic crystalloid (e.g., Normal Saline or Lactated Ringer's) per protocol or physician order.
Communication & Preparation: Notify the surgeon/rapid response team. Prepare for possible blood transfusion (check type and crossmatch status). Document everything meticulously.
Patient Safety and Precautions: Do not leave the patient alone. Avoid the full Trendelenburg position (head down) as it can impair breathing. Monitor for fluid overload during resuscitation, especially in elderly patients or those with cardiac history. Pain should be reassessed after hemodynamic stabilization.
Nursing Procedure & Medication FlowFluid Resuscitation: For an adult in hypovolemic shock, a common order is a fluid challenge of 500-1000 mL of isotonic crystalloid over 15-30 minutes. Use an infusion pump or pressure bag. Reassess vital signs and lung sounds after each bolus.
Blood Administration: If hemorrhagic shock is confirmed, prepare for transfusion. Remember the checks: physician order, informed consent, two-nurse verification at the bedside against the patient's ID band, starting slowly for the first 15 minutes, monitoring for transfusion reactions.
A Word from Your Senior Nurse
"In a crisis, your brain might scream 'Call the doctor!' or 'Get the IV!'. Train your muscle memory to think ABC first. Positioning and oxygen are the tools you always have with you. That quick action buys time for everything else. On the NCLEX and in real life, showing you know how to buy that time for your patient is what makes a safe, competent nurse. Always ask yourself: 'What can I do RIGHT NOW with what's in this room?'"
Hypovolemic Shock — A life-threatening condition where severe blood or fluid loss makes the heart unable to pump enough blood to the body, leading to organ failure.
ABCDE Approach — A systematic clinical assessment tool used in emergencies: Airway, Breathing, Circulation, Disability, Exposure.
Modified Trendelenburg Position — A position where the patient lies supine with the legs elevated approximately 20-30 degrees, used to increase venous return in hypovolemic states.
Oliguria — Decreased urine output, typically defined as less than 400 mL per day or less than 0.5 mL/kg/hr in adults. A key sign of poor renal perfusion.
Independent Nursing Intervention — Actions a nurse can initiate without a physician's order, based on clinical judgment and knowledge (e.g., positioning, education, comfort measures).
