A nurse is teaching a child the correct use of a metered-dose inhaler (MDI). Which statement by the child indicates a need for further teaching?

Appeared in: NORCET 10 Prelims-2026

Explanation

The statement about inhaling for 20 to 30 seconds is incorrect and indicates a significant misunderstanding of the procedure.
The correct technique involves inhaling slowly and deeply for 3 to 5 seconds while activating the inhaler.
The child has confused the inhalation duration with the waiting period between puffs, which is typically 20 to 30 seconds.
This error would lead to ineffective medication delivery and poor symptom control, highlighting a critical need for re-education.

Option A: This statement is correct. Shaking the inhaler for 2-5 seconds is a crucial step to mix the medication with the propellant, ensuring a consistent dose is delivered.
Option B: This statement is correct. Exhaling completely before inhalation empties the lungs, creating space to take a full, deep breath of the medication, which helps it reach deep into the airways.
Option C: This statement, while poorly phrased, refers to the correct concept of a 3 to 5-second inhalation. It does not represent a misunderstanding as critical as the incorrect option.

Clinical Relevance

Nursing practice connection: Use the key finding related to Patient Education for Medication Administration to guide bedside assessment, documentation, and the next nursing action.
Proper MDI technique is crucial for effective asthma and COPD management. Incorrect technique is a primary cause of treatment failure.
For children, using a spacer or valved holding chamber with an MDI is highly recommended. It eliminates the need for coordinating breath and actuation, and increases the amount of medication delivered to the lungs.
What if the inhaler contained a corticosteroid? The nurse must add the instruction to rinse the mouth with water and spit it out after use to prevent oral thrush (candidiasis).

How to Approach the Question

First, identify the core of the question: it's asking you to find the incorrect statement about MDI use, which signals a need for more teaching.
Mentally review the standard steps for using an MDI: Shake, Exhale, Inhale (slowly, 3-5 sec), Hold breath (10 sec), Wait between puffs.
Read each option and compare it against your knowledge of the correct procedure.
Option A ('shake') is correct. Option B ('exhale fully') is correct. Option C ('3 to 5 second inhalation') refers to a correct timeframe.
Analyze Option D: 'inhale... for 20 to 30 seconds'. This is a very long time to inhale and is physically difficult. Recognize that this number is associated with the waiting period between puffs, not the inhalation itself. This is the error.
Conclude that the statement in Option D is factually incorrect and demonstrates a clear misunderstanding, thus requiring further teaching.
