Pleural Disorders and Chest Tubes PNLE Questions

Introduction

This companion covers 28 original PNLE-style practice questions in Tangerine Prep’s Pleural Disorders and Chest Tubes set. The inventory includes pneumothorax, hemothorax, pleural effusion, chest-tube care, and thoracic trauma, so practice centers on connecting assessment findings to a safe nursing action.

You will decide which cues suggest air or fluid in the pleural space, whether a change indicates worsening compromise or expected re-expansion, how to inspect a drainage system, and when to escalate. You will also practice procedure and postoperative decisions, including tube patency, disconnection, removal, positioning, and operation-specific precautions. Pulmonary embolism and generalized respiratory failure are outside this topic’s canonical scope.

This is a Tangerine pedagogical lens within NP4, Medical-Surgical. It is mapped across relevant competencies in the official five-subject PNLE TOS, rather than being a separate official test subject. The 2025 Enhanced TOS provides broad competency relationships and does not assign a guaranteed microtopic weight, so the 28-question inventory should guide practice, not predict the exact distribution of any exam form.

Key concepts

Air versus fluid in the pleural space
Recognize: Pneumothorax involves air, while hemothorax and pleural effusion involve fluid that can restrict lung expansion. Unilateral breath-sound changes must be interpreted with the history and other assessment findings.
Decide: Connect the likely pleural process with the patient’s respiratory effort, chest movement, hemodynamic status, and need for prompt escalation.
Avoid: Naming the disorder from reduced breath sounds alone or treating pneumothorax, hemothorax, and effusion as interchangeable.
Thoracic assessment and escalation
Recognize: Sudden dyspnea, increasing work of breathing, unequal chest movement, worsening breath sounds, tracheal deviation, hypotension, or altered mentation can signal deterioration, especially after trauma or a procedure.
Decide: Assess the patient first, prioritize airway and breathing, call for urgent help when instability is present, and report meaningful changes promptly.
Avoid: Delaying action while completing a routine equipment check when the patient shows signs of acute compromise.
Chest-tube patency and system position
Recognize: Kinks, dependent loops, compression, loose connections, and an improperly positioned collection system can interfere with drainage or create misleading findings.
Decide: Trace the tubing from the patient to the collection system, keep the system upright and below chest level, and correct a visible mechanical problem according to protocol.
Avoid: Pulling on the tube, repeatedly stripping it, or assuming that absent drainage automatically means the lung has re-expanded.
Water-seal and drainage observations
Recognize: Chamber movement, bubbling, and drainage trends must be interpreted according to the type of system, the patient’s respiratory pattern, and the clinical situation. Continuous bubbling in a water-seal chamber may indicate an air leak.
Decide: Correlate chamber observations with respiratory assessment and inspect connections before reporting or intervening.
Avoid: Calling every bubble abnormal or declaring the system normal from one observation without assessing the patient.
Disconnection, dislodgement, and removal
Recognize: A disconnected system, a tube pulled from the patient, and a tube that stops draining are different problems requiring different responses.
Decide: Assess breathing, summon assistance, restore a closed system or protect the insertion site according to institutional protocol, and use the prescribed removal technique with appropriate reassessment.
Avoid: Clamping routinely, leaving an open connection unattended, or removing a tube without confirming the order and required respiratory maneuver.
Trauma and operation-specific precautions
Recognize: Paradoxical chest-wall motion suggests flail chest, while postoperative patients may have restrictions related to the specific thoracic procedure, such as lobectomy or pneumonectomy.
Decide: Stabilize assessment priorities, follow the operative plan, and verify positioning, suction, and chest-tube instructions rather than applying a universal rule.
Avoid: Treating every postoperative chest-tube patient alike or applying routine suctioning and positioning without checking the prescribed plan.

What to expect on the PNLE

The 28-question inventory supports several forms of nursing reasoning. Assessment-to-action vignettes can ask you to interpret unilateral findings, thoracic-trauma signs, or a sudden postoperative change and select the safest priority. Equipment items can require tracing a kink, dependent loop, loose connection, disconnection, or a change in the drainage system before choosing an intervention.

Procedure and positioning questions test whether you can follow the ordered technique, protect the closed system, and adapt care to the operation. Pathophysiology items ask you to explain how air or fluid in the pleural space affects expansion and breath sounds. The live difficulty distribution is easy=6, medium=13, hard=9. The Bloom distribution is applying=13, understanding=7, remembering=4, analyzing=2, and evaluating=2, so read for a clinical decision rather than isolated recall.

Recognition: Link assessment cues with the likely pleural process.
Application: Choose the next safe nursing action in a patient or equipment situation.
Analysis: Separate a patient deterioration from a drainage-system problem or expected change.
Evaluation: Rank competing actions using urgency, patient stability, and procedure-specific safety.

For every item, identify the patient cue, verify the equipment or procedure context, then rank immediate safety actions. Exact topic distribution varies by exam form; this inventory indicates the kinds of reasoning to rehearse, not a guaranteed topic count.

Study tips

Start with diagnostic practice. Complete a first pass through the 28-question inventory before reviewing rationales. Mark each response as confident, guessed, or unknown, and record the cue that drove your choice.
Use focused retrieval. On a blank page, create separate sections for pneumothorax, hemothorax, pleural effusion, chest-tube care, and thoracic trauma. From memory, write the defining mechanism, assessment cues, priority action, and reassessment cue for each section.
Review rationales by error type. For every missed or guessed item, identify whether the problem was recognition, prioritization, equipment interpretation, or procedure safety. Make this comparison chart yourself:
Condition or problem | Key cue | Immediate nursing decision | Reassessment
Pneumothorax | air-related findings | assess and escalate as indicated | breathing and chest movement
Tube problem | kink, loop, or loose connection | inspect and correct per protocol | drainage and patient status
Trauma | paradoxical motion or instability | prioritize urgent assessment | response and vital signs
Retry with spacing. Return to missed items after a separate study interval. Explain the correct decision aloud without looking at the answer, then compare your explanation with the rationale.
Finish with mixed timed practice. Mix disorder recognition, drainage-system troubleshooting, trauma assessment, and postoperative precautions. Review timing and errors only after the set, then choose the next focused retrieval task.

Common mistakes to avoid

Using reduced breath sounds as the diagnosis. This finding can occur with more than one pleural disorder. Correct the error by combining it with the mechanism, trauma or procedure history, chest movement, respiratory effort, and hemodynamic cues.
Inspecting the equipment before assessing an unstable patient. A kink or disconnection matters, but sudden dyspnea, tracheal deviation, hypotension, or altered mentation raises the priority of immediate patient assessment and escalation.
Clamping or stripping the tube reflexively. Routine clamping or forceful manipulation can obstruct drainage or worsen pressure problems. Maintain patency and clamp only when specifically ordered or required by a defined emergency protocol.
Misreading chamber bubbling or movement. The meaning depends on the chamber, system design, respiratory pattern, and clinical context. Correlate the observation with the patient and inspect for an air leak or mechanical problem before deciding that it is expected.
Applying one postoperative rule to every thoracic operation. Positioning and suction decisions may depend on the procedure and prescription. Check the operative plan and follow operation-specific instructions, particularly when pneumonectomy or lobectomy is involved.
Underestimating thoracic-trauma findings. Paradoxical chest-wall motion, worsening effort, unequal expansion, or circulatory changes require prompt reassessment. Use the safety principle of prioritizing airway, breathing, and circulation instead of waiting for a routine chest-tube task to be completed.

Try a question

A real Pleural Disorders and Chest Tubes question from our bank. Give it a shot.

Hard

A client with a chest tube becomes dyspneic, and tidaling stops. The tubing is kinked under the bed rail. What should the nurse do?

A

Clamp the tube, unkink it, then assess the client

B

Unkink the tube and reassess at the next vital-sign interval

C

Unkink the tubing, assess the client, and reassess drainage

D

Raise the drainage system to rail level before unkinking it

Rationale

A client with a chest tube who suddenly becomes dyspneic and whose tubing no longer shows tidaling (the rise and fall of fluid in the water-seal chamber with respiration) is experiencing an interruption in normal chest drainage system function. Identifying and resolving the cause immediately is essential to prevent complications like tension pneumothorax or reaccumulation of air/fluid in the pleural space.

Why Option C is Correct
Unkinking the tubing addresses the mechanical obstruction to chest tube drainage, restoring patency and allowing trapped air or fluid to drain. Immediately assessing the client is critical because dyspnea may signal worsening respiratory status, impaired lung re-expansion, or reaccumulation of air. Reassessing drainage ensures the system is functioning after intervention and helps detect ongoing or new problems. This approach follows best practices in chest tube management: maintain system patency, monitor patient response, and frequently reassess for complications.

Why the Other Options Are Incorrect

Option	Why It Is Incorrect
A	Clamping the tube is only indicated in specific situations (e.g., system change, accidental disconnection), and even then, for as short a time as possible. Clamping can lead to tension pneumothorax by trapping air under pressure in the pleural space. Unkinking first and then promptly assessing is safer.
B	Delaying reassessment until the next vital sign interval is unsafe. Dyspnea and loss of tidaling are significant changes; the nurse must act and reassess the client and system immediately, not wait.
D	Raising the drainage system to rail level is unsafe. The chest tube drainage system should always remain below chest level to facilitate effective gravity drainage. Raising it can cause fluid backflow and compromise drainage.

Nursing Concepts & Clinical Reasoning
This scenario tests your understanding of chest tube management and prioritization in clinical practice. Key concepts include airway and breathing assessment, recognition of high-risk changes (dyspnea, system dysfunction), and knowing the purpose/management of chest tubes (remove air/fluid, restore negative pressure). Prompt detection and correction of system problems are fundamental to safe patient outcomes.

Relevant Pathophysiology
Chest tubes restore negative intrapleural pressure, allowing lung re-expansion. If drainage is blocked (e.g., by a kink), negative pressure is lost, air/fluid can accumulate, and the client may become dyspneic. If not corrected, this can rapidly progress to acute respiratory distress or tension pneumothorax.

Clinical Pearl: Remember "PATENCY FIRST": Always check for and correct physical disruptions (kinks, disconnections, clots) in drainage before assessing further or calling the provider. Assessment and monitoring immediately follow correction.
