Decannulation means:

Appeared in: AIIMS Delhi NO-2016

Explanation

Decannulation is the specific medical term for the planned and permanent removal of a tracheostomy tube.
This procedure is performed when the patient can maintain a clear airway, breathe independently, and manage secretions without the need for the tube.
The term originates from 'de-' (meaning removal) and 'cannula' (the tube itself), which accurately describes a tracheostomy tube.

Option B: The removal of an intravenous (I/V) cannula is commonly referred to as 'IV removal' or 'discontinuing an IV line,' not decannulation.
Option C: The removal of a nasogastric (NG) tube is simply called 'NG tube removal.' It does not have a specific single-word medical term like decannulation.
Option D: The correct medical term for the removal of an endotracheal (ET) tube is 'extubation.'.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Medical Terminology: Airway Management as background academic context rather than a clinical decision trigger.
Nurses play a crucial role in assessing a patient's readiness for decannulation, which includes evaluating their ability to cough, swallow, and maintain oxygen saturation without suctioning.
Post-decannulation monitoring is critical to immediately identify and manage complications like respiratory distress, stridor, or laryngospasm. Emergency equipment, including a spare tracheostomy tube, should be at the bedside.
What if? If a patient shows signs of respiratory distress (e.g., stridor, decreased SpO2) immediately after decannulation, the priority nursing action is to call for immediate assistance, prepare for potential re-intubation, and apply supplemental oxygen as needed.

How to Approach the Question

This is a factual recall question testing knowledge of specific medical terminology.
Identify the key term in the question: 'Decannulation.'
Recall the definition of this term from your study of airway management procedures.
Evaluate each option to see which one matches the precise definition.
Eliminate options that describe the removal of other types of tubes, recalling their specific terminology if applicable (e.g., 'extubation' for ET tubes) to confirm they are incorrect.
