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.

Explanation
A. The septum refers to the nasal septum, which divides the nasal cavity into two nostrils. It is not part of the pharynx.
B. The oropharynx is located below the nasopharynx and serves as a passage for both air and food. It is not the most superior portion of the pharynx.
C. The nasopharynx is the most superior portion of the pharynx, located behind the nasal cavity and above the soft palate. It is primarily involved in the passage of air from the nasal cavity to the rest of the respiratory system.

Correct Answer is D
Explanation
A. Tachypnea refers to rapid breathing. While it can affect the balance of gases in the blood, it typically leads to decreased CO₂ levels, which would actually reduce blood acidity (increase pH).
B. Dyspnea refers to difficult or labored breathing. It can be associated with respiratory distress, but it does not directly cause significant changes in blood acidity.
C. Hyperpnea is characterized by increased depth and rate of breathing, often to meet metabolic demands, like during exercise. This typically decreases CO₂ levels, which can lead to a reduction in blood acidity (increase in pH).
D. Apnea, which is the cessation of breathing, would lead to a buildup of CO₂ in the blood because the body is not expelling it through normal respiration. This increase in CO₂ would combine with water to form carbonic acid, thereby lowering blood pH and increasing acidity.
