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. Epistaxis refers to nosebleed, which is unrelated to lung function or expansion.
B. Effusion refers to the accumulation of fluid (such as pleural effusion, where fluid collects in the pleural space around the lungs), not incomplete lung expansion.
C. Atelectasis is the collapse or incomplete expansion of a lung or part of a lung, which can occur due to blockage, pressure, or injury.
D. Adhesion refers to abnormal fibrous connections between tissues, which can occur in the body after injury or surgery, but it does not refer to incomplete lung expansion
Correct Answer is D
Explanation
A. Allergic rhinitis is an allergic reaction to airborne particles like pollen or dust, and while it affects the upper respiratory system, it is not an infection.
B. COPD (Chronic Obstructive Pulmonary Disease) is a chronic condition that affects the lower respiratory system, especially the lungs, but it is not an infection.
C. Tuberculosis (TB) is a bacterial infection that primarily affects the lungs and is considered a lower respiratory infection, not an upper respiratory infection.
D. Acute Coryza is commonly known as the common cold, which is an upper respiratory infection caused by viruses such as rhinoviruses. It affects the nasal passages, throat, and sinuses.
