해설
In chest trauma with pneumothorax, assessing for tension pneumothorax is the highest priority due to its life-threatening nature. Other options are important but secondary to immediate recognition of this emergency.
Core Nursing ExplanationKey Concept Analysis: This question tests the nurse's ability to prioritize care for a patient with a Chest tube following traumatic Pneumothorax. The core principle is Airway, Breathing, Circulation (ABC) and recognizing life-threatening complications. A Tension pneumothorax occurs when air enters the pleural space but cannot escape, causing a one-way valve effect. This leads to a rapid increase in intrapleural pressure, collapsing the lung, shifting the Mediastinum to the opposite side, and compressing the great vessels and the other lung. This is a true medical emergency that can lead to Cardiovascular collapse and death within minutes if not treated.
Answer Rationale: Key Point! Assessing for signs of Tension pneumothorax is the highest priority because it is an immediate threat to life. Key signs include severe dyspnea, tracheal deviation away from the affected side, distended neck veins (JVD) due to impaired venous return, hypotension, tachycardia, and subcutaneous emphysema (crepitus). The chest tube is in place to prevent this, but it can become occluded or dislodged, so constant vigilance is required. This action directly aligns with the nursing process of Assessment for a critical, unstable condition.
Distractor Analysis:
Option 1 (Administer pain medication): While pain management is crucial for patient comfort and to facilitate deep breathing, it is a supportive intervention, not the priority when a life-threatening complication must be ruled out first.
Option 2 (Encourage deep breathing and coughing): This is an important Preventive measure for Atelectasis and pneumonia, but it is not the immediate priority over assessing for a condition that can cause death in minutes.
Option 3 (Monitor drainage output): This is a standard and essential nursing action for a patient with a chest tube to monitor for Hemothorax or excessive bleeding. However, it is a monitoring task. A sudden change in vital signs (indicating tension pneumothorax) would be assessed before checking the specific drainage amount.
Related Concepts: The question integrates trauma nursing, respiratory emergency management, and chest tube care. Understanding the difference between a Simple pneumothorax (air in pleural space, stable) and a Tension pneumothorax (air under pressure, unstable) is critical. The priority is always to assess for and intervene in conditions that compromise the ABCs.
Concept Summary
Concept
Description
Nursing Implication
Tension Pneumothorax
Life-threatening accumulation of air in pleural space under pressure, causing lung collapse, mediastinal shift, and cardiovascular compromise.
Closed system that allows air/fluid to exit pleural space and prevents air from re-entering. Bubbling indicates air leak; tidaling indicates patent system.
Priority is to ensure system is intact, below chest level, and not kinked. Monitor for continuous bubbling (air leak) or sudden cessation (occlusion).
Rib Fractures
Painful injury that impairs chest wall movement and increases risk of hypoventilation, atelectasis, and pneumonia.
Manage pain effectively (priority after ABCs) to enable deep breathing and coughing. Monitor for Flail chest (paradoxical movement).

Tension Pneumothorax
Pathophysiology
Air enters pleural space, equalizing pressure. Lung collapses partially or fully.
One-way valve effect: Air enters but cannot escape. Pressure builds, collapsing lung and shifting mediastinum.
Key Point!Recognize emergency and notify physician immediately. May require immediate needle decompression.
Anatomy, Physiology & Pharmacology Points
Pleural Space: The potential space between the visceral and parietal pleura. Normally has negative pressure for lung expansion. Introduction of air (pneumothorax) eliminates this negative pressure.
Mediastinal Shift: In tension pneumothorax, high pressure pushes the heart and great vessels toward the unaffected side, compressing them and reducing cardiac output (obstructive shock).
Pain Medication (e.g., Opioids): Crucial for rib fracture pain but must be administered cautiously. Monitor for respiratory depression, especially in a patient with potential respiratory compromise.
Memory Tips
Think "TENSION = TENSION on the heart and lungs." The pressure builds up, putting everything under tension.
Acronym for Tension Pneumothorax Signs: "Deviated trachea, Distended neck veins, Decreased BP, Dyspnea" (The 4 D's).
Priority Rule: In any trauma or post-procedure patient with a chest tube, always think "Could this be a tension pneumothorax?" first. ABCs come before comfort or routine monitoring.
High-Frequency NCLEX Topics
Chest tubes and pneumothorax are Core NCLEX topics. You will be tested on:
Identifying priority assessments (tension pneumothorax vs. routine care).
Proper setup and troubleshooting of water-seal drainage systems (e.g., what to do if the chamber breaks).
Normal vs. abnormal findings (tidaling, bubbling).
Patient positioning and safety (keep system below chest level, never clamp without order).
Watch Out for Question Variations!
Shift from Assessment to Intervention: "The nurse assesses tracheal deviation and hypotension in a patient with a chest tube. What is the priority intervention?" (Answer: Prepare for/assist with needle decompression and notify physician).
Focus on System Malfunction: "The chest tube drainage system is accidentally knocked over and the water seal is broken. What should the nurse do first?" (Answer: Submerge the end of the tube in sterile water to re-establish the water seal, preventing air entry).
Post-Removal Care: "A patient's chest tube was removed 2 hours ago. The nurse notes crepitus around the insertion site. What is the appropriate action?" (Answer: This is common subcutaneous emphysema; document and monitor. It becomes a concern only if it rapidly spreads to the neck/face, which could indicate ongoing air leak).
Nursing Clinical Practice GuideClinical Scenario: You are the nurse on a medical-surgical unit. Mr. Johnson, 45, was admitted after an MVC with multiple left-sided rib fractures and a pneumothorax. A 28Fr chest tube is connected to an Atrium™ water-seal drainage system. During your 0800 assessment, he appears anxious, is using accessory muscles to breathe, and his SpO2 has dropped from 96% to 90% on 2L nasal cannula.
Nursing Intervention Strategy:
Immediate Assessment (ABCs):
Airway: Patent but patient is tachypneic.
Breathing: Auscultate lungs. You note absent breath sounds on the left and now palpate a slight tracheal deviation to the right. Check the chest tube system: The water seal chamber is not tidaling with respiration, and there are no bubbles. The tubing appears kinked under the patient's arm.
Circulation: Check vital signs: HR 124, BP 88/50, capillary refill >3 seconds. Assess for JVD, which is now present.
Priority Action: This cluster of findings (hypotension, tachycardia, tracheal deviation, JVD, absent breath sounds, and a non-functioning chest tube) points to Key Point!tension pneumothorax.
First: Call for help and notify the physician/respiratory therapist immediately while staying with the patient.
Simultaneously: Attempt to troubleshoot the obvious cause—carefully unkink the chest tube tubing. If the system is occluded and unkinking doesn't restore tidaling/bubbling, the physician may need to emergently replace the tube or perform needle decompression.
Increase oxygen delivery (non-rebreather mask) as ordered.
Post-Emergency Care: Once the emergency is resolved (e.g., new chest tube placed, patient stabilized), then proceed with the other important tasks: administer pain medication, encourage coughing and deep breathing with splinting, and meticulously document the drainage output and the entire event.
Patient Safety and Precautions:
Never clamp a chest tube routinely or for transport unless specifically ordered (e.g., to assess for an air leak). Clamping can rapidly cause a tension pneumothorax if there is an ongoing air leak.
Keep the drainage system below the level of the patient's chest at all times to prevent backflow of fluid or air into the pleural space.
Monitor for excessive drainage: Notify the physician for output > 100 mL/hr or a sudden increase, which may indicate active bleeding.
Nursing Procedure & Medication FlowChest Tube System Check (Q1H and PRN):
Water Seal Chamber: Should show tidaling (fluctuation with respiration). Absent tidaling may indicate lung re-expansion or an occlusion.
Suction Control Chamber: Ensure gentle, continuous bubbling if suction is ordered. Vigorous bubbling indicates suction is too high.
Drainage Collection Chamber: Mark level and character of fluid hourly. Bloody drainage is expected initially but should gradually decrease.
Assess Tubing: Ensure no kinks, loops, or dependent sections. Tape connections securely.
Pain Management: Administer analgesics (e.g., IV morphine) 30 minutes before planned activity or coughing/deep breathing exercises to maximize participation.
A Word from Your Senior Nurse
"In trauma and critical care, your assessment skills are your most powerful tool. A patient with a chest tube isn't just a 'drainage system' to manage—they are a person whose respiratory status can change in an instant. Always look at the patient first, not just the equipment. That subtle tracheal shift or sudden anxiety might be your only early clue to a tension pneumothorax before the blood pressure drops. On the NCLEX, they test this prioritization constantly. In real life, it saves lives. Connect the dots between the pathophysiology (trapped air causing pressure) and the clinical signs (deviation, JVD). That's what makes a safe, competent nurse."
Tension Pneumothorax — A life-threatening condition where air accumulates in the pleural space under pressure, causing lung collapse, mediastinal shift, and impaired cardiac output. It is a medical emergency.
Water-Seal Drainage — A closed chest drainage system that uses a water column to allow air and fluid to exit the pleural space while preventing air from re-entering. The water seal chamber should show tidaling (fluctuation with respiration).
Tracheal Deviation — A physical assessment finding where the trachea is shifted from its midline position. Deviation away from the affected side is a classic sign of tension pneumothorax.
Jugular Venous Distension — Visible bulging of the jugular veins in the neck, indicating increased central venous pressure. In tension pneumothorax, it is caused by compression of the superior vena cava due to mediastinal shift.
Needle Decompression — An emergency procedure for tension pneumothorax involving insertion of a large-bore needle into the 2nd intercostal space, midclavicular line, to release trapped air and relieve pressure.
