Explanation

The question asks to identify the incorrect statement about MDI use in a child, which implies proper technique.
Proper MDI technique in children requires a spacer device to overcome coordination challenges and reduce side effects.
A primary benefit of using a spacer is the significant reduction of medication deposition in the oropharynx (mouth and throat).
This reduction in deposition directly minimizes local side effects, including oropharyngeal irritation and fungal infections.
Therefore, oropharyngeal irritation is not an expected or correct outcome of proper MDI use with a spacer; it is an adverse effect that the technique is designed to prevent.

Option A: This statement is correct. The primary purpose of an MDI is to deliver medication directly into the lungs for a local therapeutic effect.
Option C: This statement is correct. Bronchodilator medications administered via MDI, such as Albuterol, work by relaxing airway smooth muscle, leading to the expansion and dilation of the bronchi.
Option D: This statement is correct, although confusingly worded. Using a spacer reduces the amount of drug deposited in the oropharynx. Consequently, less drug is available to be swallowed or 'evacuated' from the mouth and throat.

Clinical Relevance

Nursing practice connection: Use the key finding related to Metered-Dose Inhaler (MDI) with Spacer Technique in Pediatrics to guide bedside assessment, documentation, and the next nursing action.
Proper patient and family education on MDI with spacer technique is a critical nursing responsibility to ensure treatment efficacy and prevent side effects.
Incorrect technique leads to underdosing and poor management of respiratory conditions like asthma, potentially resulting in exacerbations.
Nurses must assess the patient's technique regularly and provide corrective feedback. Cleaning the spacer is also important to prevent static charge buildup, which can reduce drug delivery.

How to Approach the Question

First, identify the negative framing of the question ('What is incorrect?'). This means you are looking for the false statement or the option that does not fit.
Recall the standard of care for the procedure in the given population. For a child using an MDI, this involves a spacer.
Evaluate each option based on the function and benefits of using an MDI with a spacer.
Option A ('Drugs deposited into the lungs') is the main goal. This is correct.
Option C ('Expansion & dilation of bronchus') is the desired therapeutic effect of the medication. This is correct.
Option D ('Reduced drug evacuation from oropharynx') describes a benefit of the spacer (less drug swallowed). This is correct.
