Chest-tube and drainage-system management is a hands-on med-surg skill the CMSRN tests. Practice the water-seal, tidaling, and air-leak troubleshooting scenarios below with full rationales.
Question 1
While preparing a sterile field for chest tube insertion, the nurse notices a 1cm tear in the sterile package wrapper corner. The patient is immunocompromised from recent chemotherapy. Which action is warranted?
- A) A) Use the contents since the tear is small and away from the main sterile area
- B) B) Discard the package and open new supplies using aseptic technique✓
- C) C) Inspect inner packaging for integrity before deciding to use contents
- D) D) Apply sterile tape over the tear and proceed with field preparation
Show rationale
Any compromised packaging invalidates sterility per CDC guidelines. The tear allows microbial entry, and the immunocompromised patient faces high infection risk. Option A ignores that even small tears breach sterility. Option C is incorrect because outer wrapper damage contaminates contents regardless of inner appearance. Option D violates standards as taping doesn't restore sterility.
Question 2
During an active shooter event in the ER, a medical-surgical nurse receives three trauma patients with gunshot wounds. Patient 1 has a chest wound with SpO2 89%, Patient 2 has a femur fracture with rapid swelling, and Patient 3 has a bleeding scalp laceration. Which patient should be prioritized for immediate intervention based on disaster triage principles?
- A) A) Patient 1 due to potential tension pneumothorax and hypoxia✓
- B) B) Patient 2 due to risk of compartment syndrome and hemorrhage
- C) C) Patient 3 due to uncontrolled bleeding and shock risk
- D) D) Patient 1 due to airway compromise requiring rapid intubation
Show rationale
START triage prioritizes airway/breathing threats. Patient 1's low SpO2 and chest wound suggest life-threatening pneumothorax. Option B's femur fracture, while urgent, is less immediately lethal than hypoxia. Option C's scalp laceration typically causes less rapid blood loss than truncal wounds. Option D incorrectly assumes intubation is indicated; initial management for suspected pneumothorax is needle decompression, not intubation. ATLS guidelines emphasize treating breathing compromise before hemorrhage control in multi-trauma cases.
Question 3
A postoperative patient with severe COPD and baseline SpO2 of 89% on 2L NC oxygen suddenly triggers a high-pressure ventilator alarm. The patient is diaphoretic with asymmetrical chest rise and new-onset tachycardia. Which troubleshooting action takes precedence?
- A) A) Increase oxygen concentration to maintain SpO2 above 92% per protocol
- B) B) Perform endotracheal suctioning to clear potential mucus plugs
- C) C) Disconnect ventilator and manually bag-valve-mask ventilate immediately
- D) D) Assess tube placement and listen for bilateral breath sounds first✓
Show rationale
Asymmetrical chest rise suggests tube displacement or pneumothorax, requiring immediate assessment before intervention (cue: COPD increases barotrauma risk). Option D addresses the high-pressure alarm's most critical cause while avoiding unnecessary manipulation. Option A ignores the alarm cause and risks oxygen toxicity in COPD. Option B could worsen obstruction if displacement exists. Option C removes ventilator support prematurely without assessment, risking rapid decompensation. Guidelines prioritize systematic assessment before action to avoid iatrogenic harm.
Question 4
A postoperative patient on a ventilator in synchronized intermittent mandatory ventilation (SIMV) mode has frequent high-pressure alarms. The nurse observes decreased breath sounds on the right and 88% SpO₂. Chest X-ray reveals right pneumothorax. Which ventilator setting adjustment best addresses this equipment-patient mismatch?
- A) A) Increase PEEP to improve oxygenation and alveolar recruitment
- B) B) Switch to pressure control ventilation with lower inspiratory pressure
- C) C) Reduce tidal volume while maintaining current respiratory rate✓
- D) D) Elevate FiO₂ to 100% to compensate for reduced ventilation
Show rationale
Reducing tidal volume minimizes barotrauma in pneumothorax. Option A increases intrathoracic pressure, worsening pneumothorax. Option B doesn't address volume-induced injury. Option D masks hypoxia without correcting ventilation. ARDS Network protocols prioritize low tidal volumes for lung protection in barotrauma. The cues (pneumothorax, high-pressure alarms) indicate volutrauma risk, making C the safest adjustment.
Question 5
While receiving handoff for four patients, the nurse hears: "Room 304 – total hip replacement, ready for discharge; Room 305 – new chest tube, drainage 200ml/hr; Room 306 – COPD exacerbation, BiPAP at night; Room 307 – DNR, sepsis on antibiotics." Which patient requires handoff prioritization?
- A) A) Room 304 with discharge readiness requiring education
- B) B) Room 305 with high chest tube output indicating bleeding✓
- C) C) Room 306 needing nocturnal BiPAP setup verification
- D) D) Room 307 under sepsis protocol with DNR status
Show rationale
Drainage exceeding 200ml/hr (cue 1) suggests active hemorrhage, an acute threat per CMSRN prioritization frameworks. Room 307's sepsis is stable on treatment (cue: antibiotics ongoing). Room 304/306 issues are non-urgent. Option B addresses a potential emergency, while others involve stable or routine care. AMSN guidelines emphasize prioritizing unstable physiological conditions; chest tube output >150ml/hr requires immediate evaluation, making it highest risk.
Question 6
A trauma patient with rib fractures receiving epidural analgesia suddenly develops SpO2 88%, asymmetrical chest movement, and subcutaneous emphysema. Which hypothesis should the nurse validate first?
- A) A) Pneumothorax progression requiring chest tube evaluation✓
- B) B) Epidural catheter migration causing respiratory depression
- C) C) Pulmonary embolism necessitating anticoagulation
- D) D) Opioid overdose requiring naloxone administration
Show rationale
Asymmetrical chest movement and subcutaneous emphysema are classic for pneumothorax, exacerbated by rib fractures. SpO2 drop aligns with this, not epidural effects (B) which typically cause symmetrical hypoventilation. PE (C) lacks hemoptysis or calf pain. Opioid overdose (D) would show pinpoint pupils and reduced respiratory effort. ATLS protocols prioritize tension pneumothorax assessment before neurological causes.
Question 7
A nurse prepares a sterile field for a chest tube insertion in a COPD patient with oxygen via nasal cannula at 4 L/min. While arranging instruments, the oxygen tubing dislodges and touches the field's edge. Which intervention aligns with aseptic principles?
- A) A) Adjust the oxygen tubing and cover the contacted area with sterile drape
- B) B) Discard the entire sterile field and prepare new equipment✓
- C) C) Clean the contacted area with sterile saline and continue
- D) D) Rotate the drape so the contaminated edge faces away
Show rationale
Oxygen tubing at high flow is a fomite risk in COPD patients; field edges are critical zones. Complete field replacement prevents pathogen introduction to pleural space. Option A increases contamination risk: covering doesn't sterilize. Option C is inadequate: saline doesn't disinfect. Option D violates sterility principles: rotating doesn't eliminate contamination. CDC standards require discarding fields contacting non-sterile objects during invasive procedures.
Question 8
A tracheostomy patient 3 days post-insertion develops acute dyspnea and frothy pink secretions. Assessment reveals absent breath sounds over the left lung and tracheal deviation. Which action is most urgent?
- A) A) Suction the tracheostomy tube with hyperoxygenation
- B) B) Deflate the tracheostomy cuff and auscultate breath sounds✓
- C) C) Remove the inner cannula and attempt manual ventilation
- D) D) Administer IV furosemide and obtain emergency chest X-ray
Show rationale
Tracheal deviation and absent breath sounds indicate possible tension pneumothorax from cuff overinflation. Deflating relieves pressure immediately. Option A may worsen barotrauma; frothy secretions suggest pulmonary edema, not mucus plugs. Option C ignores that tube displacement would cause bilateral issues. Option D treats cardiogenic edema but misses mechanical obstruction cues. AACN guidelines prioritize cuff pressure checks for acute tracheostomy distress before pharmacological interventions.
Question 9
A nurse in a bombing MCI identifies a patient with a sucking chest wound, SpO2 92% on room air, and tachycardia. After applying an occlusive dressing, breath sounds improve. Next triage action is:
- A) A) Reclassify as Delayed (Yellow) since life threat was mitigated
- B) B) Maintain Immediate (Red) due to ongoing oxygenation compromise risk✓
- C) C) Assign Minimal (Green) after confirming stable vital signs
- D) D) Upgrade to Expectant (Black) if respiratory decline occurs within 5 minutes
Show rationale
Tension pneumothorax risk persists despite initial stabilization; tachycardia and marginal SpO2 indicate unresolved compromise. Option A underestimates recurrence potential. Option C ignores abnormal vital signs. Option D delays necessary monitoring—re-triage occurs continuously, but current status remains Red.
Question 10
A patient is receiving negative pressure wound therapy for a stage 4 pressure injury. The device repeatedly alarms for a leak, but the nurse observes an intact transparent dressing. Which intervention should the nurse implement?
- A) Apply extra transparent film around the edges of the dressing.✓
- B) Remove the entire dressing and apply a completely new setup.
- C) Decrease the negative pressure setting until the alarm finally stops.
- D) Instill sterile normal saline into the tubing to clear blockages.
Show rationale
When a negative pressure wound therapy device alarms for a leak despite an apparently intact dressing, the issue is often caused by invisible micro-leaks at the dressing margins or tubing connections. The most appropriate initial step is reinforcing the edges with additional transparent film to seal the leak. Removing the entire dressing is premature, costly, and disrupts the wound bed unnecessarily. Decreasing the pressure setting is incorrect because it compromises the therapeutic efficacy of the treatment. Instilling normal saline is a technique used for clearing blockages in specific instillation setups, not for resolving air leaks.
Question 11
A patient with a pleural chest tube for a pneumothorax exhibits continuous bubbling in the water seal chamber and reports a new onset of shortness of breath. Which action should the nurse prioritize?
- A) Increase the wall suction until the continuous bubbling finally stops.
- B) Clamp the chest tube at the insertion site to assess.
- C) Document the expected finding and continue to monitor the patient.
- D) Auscultate lung sounds and inspect the entire system for leaks.✓
Show rationale
While intermittent bubbling in the water seal chamber is normal during exhalation or coughing with a pneumothorax, continuous bubbling indicates an active air leak in the system. Combined with new shortness of breath, this suggests respiratory compromise. The nurse must auscultate lung sounds and inspect the tubing from the insertion site to the collection chamber to locate the breach. Increasing wall suction will only exacerbate the air leak. Clamping the chest tube is dangerous as it can rapidly precipitate a tension pneumothorax. Documenting this as an expected finding ignores a critical complication.
Question 12
Approximately 15 minutes after a bedside thoracentesis, the patient reports the sudden onset of a persistent, dry cough and mild chest discomfort. Which action should the nurse take?
- A) Administer the prescribed as-needed intravenous pain medication.
- B) Prepare the patient for an immediate chest radiograph.✓
- C) Assist the patient into a supine resting position.
- D) Encourage deep breathing exercises using an incentive spirometer.
Show rationale
A sudden, persistent dry cough following a thoracentesis is a classic clinical indicator of a potential pneumothorax, which occurs if the visceral pleura is punctured. The best action is to prepare for a chest radiograph to confirm lung expansion and rule out complications. Administering pain medication masks a critical symptom of a procedural complication. Assisting the patient to a supine position can worsen respiratory distress if a pneumothorax is developing. While incentive spirometry is useful for general lung expansion, it is not the priority intervention when an acute complication is suspected.
Question 13
A physician is preparing to perform a bedside chest tube insertion on a patient who is experiencing a large pleural effusion. The patient is sedated and unable to communicate due to recent pain medication administration.
- A) Verify the correct patient and site with the team.✓
- B) Proceed with the insertion since the consent is signed.
- C) Ask the patient's family to confirm the procedure site.
- D) Delay the procedure until the patient is fully awake.
Show rationale
The implementation of a safety checklist requires a universal protocol time-out immediately before starting any invasive bedside procedure to confirm the correct patient, procedure, and site among the team members. Option A correctly applies this standard. Option B is unsafe because a signed consent does not replace the mandatory time-out process. Option C is incorrect because while family can provide information, the formal verification must be conducted by the clinical team performing the procedure. Option D is incorrect because urgent procedures like chest tube insertions should not be delayed simply because the patient is sedated, provided the team performs the proper safety checks.
Question 14
A patient with a carbapenem-resistant Enterobacteriaceae (CRE) urinary tract infection requires transport to the radiology department for a contrast CT scan. How should the nurse manage infection control during this patient transfer?
- A) Instruct the transport personnel to wear full contact precaution PPE during transit.
- B) Place a standard surgical mask on the patient and wrap in blankets.
- C) Ensure the patient wears a clean gown and contains the drainage system.✓
- D) Postpone the diagnostic imaging scan until the patient finishes the antibiotic course.
Show rationale
When transporting a patient with an MDRO, the primary goal is to contain the source of the infection to prevent environmental contamination. For a CRE urinary tract infection, providing a clean gown and ensuring the urinary drainage system is secure and contained effectively mitigates transmission risks. Option A is incorrect because transport personnel do not need to wear full PPE during transit unless they anticipate directly handling the patient or contaminated items; standard precautions usually suffice. Option B is incorrect because a surgical mask is utilized for droplet or airborne precautions, which are unnecessary for a contact-based infection like CRE. Option D is incorrect because necessary diagnostic testing should never be delayed solely for isolation purposes.
Question 15
A patient recovering from an open cholecystectomy with a T-tube drainage system reports sudden severe right upper quadrant pain. The nurse notes the drainage bag has been empty for four hours. Which action is required?
- A) Clamp the tube immediately to prevent further fluid volume loss.
- B) Flush the tube vigorously with sterile saline to clear obstructions.
- C) Assess the abdomen for rigidity and notify the healthcare provider.✓
- D) Elevate the drainage bag above the wound to slow output.
Show rationale
A T-tube ensures continuous drainage of bile while the common bile duct heals. Sudden, severe pain combined with a lack of drainage suggests a blocked tube leading to bile leakage into the peritoneal cavity, which can cause peritonitis. The nurse must assess for abdominal rigidity and notify the provider immediately. Clamping the tube would exacerbate the leakage and pressure. Flushing a T-tube requires a specific provider order because forceful irrigation can rupture the healing bile duct. Elevating the drainage bag above the wound promotes backflow of bile, increasing the risk of severe infection.
