Which of the following breathing patterns would result in the greatest increase in blood acidity?
Tachypnea
Dyspnea
Hyperpnea
Apnea
The Correct Answer is D
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.

Correct Answer is C
Explanation
A. Waiting 15 minutes after giving the cough syrup is unnecessary. There's typically no reason to delay giving tablets after a liquid medication unless specifically indicated.
B. Giving the cough syrup between the tablets is not an optimal approach, as it could result in potential interactions or interfere with absorption of the medications.
C. Administering the cough syrup first allows the liquid medication to be absorbed more quickly. Afterward, the tablets can be given with water to facilitate swallowing and ensure proper absorption. This order is generally most effective in promoting absorption and preventing interference between the two types of medication.
D. Administering the tablets first may lead to them being coated with the liquid, potentially delaying their absorption and effectiveness.
Correct Answer is B
Explanation
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.
