A client is experiencing an acute asthma exacerbation. The nurse administers a prescribed albuterol nebulizer treatment. Which of the following findings indicates the medication is having its intended therapeutic effect?
- AIncreased expiratory wheezing
- BImproved oxygen saturation
- CDecreased heart rate
- DIncreased anxiety and tremors
Show answer & explanationAnswer & explanation
Correct answer: B. Improved oxygen saturation
Albuterol is a short-acting beta-2 agonist (SABA) that causes bronchodilation, opening the airways. The intended therapeutic effect is improved airflow, which directly leads to better gas exchange and, consequently, improved oxygen saturation.
Why the other options are wrong
- A. Increased expiratory wheezing might initially occur as airways open and air can move more, but the ultimate goal is decreased wheezing and improved air movement. Persistent or worsening wheezing indicates ineffective treatment.
- C. Albuterol commonly causes an increased heart rate (tachycardia) as a side effect, not a decreased heart rate.
- D. Increased anxiety and tremors are common side effects of albuterol, indicating systemic absorption, but not the intended therapeutic effect on the airways.
Albuterol Therapeutic Effects
Albuterol is a bronchodilator used to relieve acute asthma symptoms. Its primary therapeutic effect is to open airways, leading to improved breathing and oxygenation.
- It's a short-acting beta-2 agonist (SABA).
- Relieves bronchospasm.
- Desired effects: decreased wheezing, improved breath sounds, increased SpO2.
Memory trick: Albuterol's breath, brings oxygen's wealth!
