A client with a prolonged upper respiratory infections seeks medical attention for symptoms of a low-grade fever, poor appetite and headache. If the client has sinusitis in the maxillary sinuses, where will she most likely report feeling pain?

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.

A. Inspiration is the phase when air is drawn into the lungs and alveoli.
B. Inhalation is synonymous with inspiration, referring to the process of taking air into the lungs.
C. Compliance refers to the ability of the lungs to stretch and expand, not a phase of ventilation.
D. Exhalation (or expiration) is the phase where air is expelled from the alveoli, moving out of the lungs and through the respiratory tract.
