The most appropriate instruction for patient during removal of a chest tube is -

Appeared in: RUHS, Jaipur, PB B.Sc Nursing Entrance-2023

Explanation

The correct instruction is to perform the Valsalva maneuver, which involves taking a deep breath and holding it while bearing down.
This action significantly increases intrathoracic (chest) pressure.
The elevated pressure prevents atmospheric air from entering the pleural space through the insertion site as the tube is withdrawn.
Preventing air entry is critical to avoid causing an iatrogenic pneumothorax (collapsed lung).

Option A: While keeping the patient calm is important for cooperation, it is a general nursing goal and not the specific physiological instruction needed to prevent a pneumothorax.
Option B: Quickly inhaling and exhaling (panting) creates unpredictable pressure changes and increases the risk of inhaling air into the pleural space at the moment of removal.
Option C: Exhaling, whether slowly or forcefully, decreases intrathoracic pressure. This creates a negative pressure gradient (a vacuum effect) that would actively suck air into the chest cavity from the outside.

Clinical Relevance

Nursing practice connection: Use the key finding related to Patient instruction for chest tube removal to guide bedside assessment, documentation, and the next nursing action.
Preventing iatrogenic pneumothorax during chest tube removal is a critical nursing responsibility. Incorrect patient instruction can lead to a life-threatening complication.
Nurses must provide clear, concise instructions and ensure the patient understands and can perform the maneuver correctly before the procedure begins.
Post-procedure monitoring is essential. The nurse must assess for signs of respiratory distress, such as sudden shortness of breath, decreased oxygen saturation, or absent breath sounds on the affected side, which could indicate a pneumothorax.

How to Approach the Question

First, identify the core concept: the safe removal of a chest tube.
Recall the anatomy and physiology of breathing. The pleural space has negative pressure. The goal is to prevent air (which is at positive atmospheric pressure) from entering this space.
Analyze each option based on its effect on intrathoracic pressure.
Inhaling decreases pressure, exhaling decreases pressure, and holding a deep breath (Valsalva) increases pressure.
Select the option that increases intrathoracic pressure, as this will prevent air from being sucked into the chest when the tube is removed.
Eliminate options that either have no effect on pressure or decrease it, as they would be ineffective or dangerous.
