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.

Correct Answer is C
Explanation
A. The external exchange of gases refers to the process of oxygen diffusing from the alveoli into the blood and carbon dioxide diffusing from the blood into the alveoli in the lungs. This occurs during pulmonary ventilation.
B. Pulmonary ventilation involves the movement of air in and out of the lungs (breathing), not the exchange of gases.
C. The internal exchange of gases refers to the diffusion of oxygen from the blood to the tissues and carbon dioxide from the tissues to the blood. This happens at the cellular level throughout the body.
D. This answer is incorrect because internal exchange of gases is the correct phase for oxygen to diffuse out of the blood.
Correct Answer is A
Explanation
A. Hemoglobin is an iron-containing protein found in red blood cells. It binds to oxygen in the lungs and carries it through the bloodstream to tissues throughout the body.
B. Antigens are substances that can trigger an immune response, but they are not involved in carrying oxygen in the blood.
C. Albumin is a protein in the blood that helps maintain osmotic pressure and transports various substances, but it does not carry oxygen.
D. Bicarbonate ions are involved in carbon dioxide transport in the blood, not oxygen. They help regulate the pH of blood and facilitate CO₂ transport from tissues to the lungs.
