Common side effects of a bronchodilator include:
Elevated WBC count and increased serum potassium
Nervousness, palpitations and tremors
Urinary retention and gynecomastia
Steven Johnson Syndrome
The Correct Answer is B
A. Elevated WBC count and increased serum potassium are not common side effects of bronchodilators. These might be seen in other conditions or medications, but not typically with bronchodilators.
B. Nervousness, palpitations, and tremors are common side effects of bronchodilators, particularly beta-agonist bronchodilators like albuterol. These symptoms occur because bronchodilators stimulate beta receptors in the body, leading to increased heart rate and stimulation of the nervous system.
C. Urinary retention and gynecomastia are more commonly associated with other medications, such as anticholinergics or certain hormonal treatments, not bronchodilators.
D. Steven Johnson Syndrome is a rare and severe skin reaction that can occur with certain medications, but it is not a common side effect of bronchodilators.
