What is the recommended rate of administration for salbutamol during treatment?

1. 50mcg (0.5 puff) every 2 breaths

2. 75mcg (0.75 puff) every 3 breaths

3. 100mcg (1 puff) every 4 breaths

4. 125mcg (1.25 puffs) every 5 breaths

The correct answer is: 100mcg (1 puff) every 4 breaths

In the context of administering salbutamol, the recommended rate of administration aligns with the established dosing guidelines for asthma and chronic obstructive pulmonary disease (COPD) management. A standard dose is typically 100 micrograms, which equates to one full puff from a metered-dose inhaler. Administering this dose every four breaths allows for adequate bronchodilation while minimizing the risk of potential side effects associated with more frequent dosing. This approach ensures that the medication can provide a sustained effect while preventing over-dosage, which could lead to complications, such as tachycardia or tremors. It follows the common practice of maximizing therapeutic benefits while keeping patient safety in mind. Other options suggest administering doses at intervals and volumes that may not align optimally with best-practice guidelines, potentially leading to less effective treatment. The correct dosing regimen allows for both immediate relief of bronchospasm and careful monitoring of the patient's response to therapy.
