Which of the following statements is CORRECT? The inflation reflex insures that the lungs will inflate enough during forced inha
lation. A decreased blood oxygen level is the strongest physiologic trigger for increased respiration. The appropriate physiologic response to hypercapnia is hyperventilation. Prolonged, severe pain will cause eupnea. Increased activity of proprioceptors will decrease the rate and depth of ventilation.
The appropriate physiologic response to hypercapnia is hyperventilation.
Explanation:
Hypercapnia is characterized by an increase in blood carbon dioxide, which usually occurs as a result of hyperventilation or inability to breathe properly to capture sufficient oxygen to the lungs. Hypercapnia may occur suddenly and cause an increase in blood acidity, called respiratory acidosis. Accordingly, we can conclude that the appropriate physiological response to hypercapnia is hyperventilation, so this is the correct statement among the options shown in the question above.
People with a history of heart or lung disease, who use cigarettes or who are exposed to chemicals on a daily basis, such as in the workplace, are at greater risk for hypercapnia.
Chronic stress, or a constant stress experienced over a prolonged period of time, can contribute to long-term problems for heart and blood vessels. The consistent and ongoing increase in heart rate, and the elevated levels of stress hormones and of blood pressure, can take a toll on the body.
