A patient is experiencing respiratory difficulty and retaining too much carbon dioxide. Which receptor sites would be stimulated in an attempt to maintain a normal homeostatic state?
a. Irritant
b. Stretch
c. Peripheral
d. Central
ANS: D
Chemoreceptors monitor arterial blood indirectly by sensing changes in the pH of cerebrospinal fluid (CSF). The central chemoreceptors are sensitive to very small changes in the pH of CSF and can maintain a normal PaCO2. Irritant receptors sense the need to expel unwanted substances. Stretch receptors decrease ventilatory rate and volume when stimulated. The peripheral chemo-receptors become the major stimulus to ventilation when the central chemoreceptors are reset.
