Which response by a patient indicates an understanding of the effects of stress on her asthma?
A) "Stress decreases my rate of breathing and makes my breathing easier."
B) "Stress decreases the amount of oxygen I need and helps my breathing."
C) "Stress dilates my airways, allowing me to get more oxygen."
D) "Stress causes inflammation of the airways which can trigger asthma attacks."
D) "Stress causes inflammation of the airways which can trigger asthma attacks."
Explanation: A) Through activation of sympathetic pathways, stress results in increased respiratory and heart rates. This results in an increase in the rate of oxygen consumption. There is evidence that psychologic stress can worsen asthma through induction of respiratory constriction. Such stress-induced inflammation could be associated with increased stress responsivity on the part of certain asthma patients.
