Explanation

The correct sequence is to administer the bronchodilator (Albuterol) before the glucocorticoid (Beclomethasone).
Albuterol is a beta-agonist that works to dilate the bronchi, or airways, in the lungs.
Administering the bronchodilator first opens the airways, which allows the anti-inflammatory glucocorticoid medication to be inhaled more deeply into the lungs, increasing its effectiveness.
A waiting period of 2 to 5 minutes between the two different medications is recommended to allow the bronchodilator to take effect.

Option A: Administering the glucocorticoid first is incorrect because its anti-inflammatory action is slow. If the airways are constricted, the medication will not penetrate deeply into the lungs, making it less effective.
Option C: Alternating the sequence with each administration is illogical and does not follow the principle of maximizing drug delivery. The rationale for the bronchodilator-first sequence is based on pathophysiology and pharmacology and should be consistent.
Option D: Medication administration order is based on clinical evidence and pharmacological principles to ensure safety and efficacy, not patient preference. Allowing preference could lead to suboptimal treatment and poor disease control.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Pharmacology: Administration sequence of inhaled bronchodilators and corticosteroids as background academic context rather than a clinical decision trigger.
Proper patient education on inhaler sequence is a critical nursing responsibility that directly impacts treatment efficacy for respiratory conditions like asthma and COPD.
Failure to follow the correct sequence can lead to poor symptom control, increased frequency of exacerbations, and wasted medication.
A key safety instruction is to always rinse the mouth after using an inhaled corticosteroid to prevent oral candidiasis (thrush), a common and preventable side effect.

How to Approach the Question

First, identify the drug classes mentioned: Albuterol is a bronchodilator (beta-agonist), and Beclomethasone is a glucocorticoid (corticosteroid).
Recall the primary action of each drug. Bronchodilators open the airways, while corticosteroids reduce inflammation.
Think logically about the goal: to get the anti-inflammatory medication as deep into the lungs as possible.
Deduce that opening the airways first with the bronchodilator would be the most effective way to achieve this goal.
This leads to the conclusion that the bronchodilator should be administered before the glucocorticoid.
