1. Chemoreceptors detect an elevation in plasmaCO2concentration. Which of the following is the most likelyresponse?
a. No change in the rate ofrespiration b. Decreasesin the rate of respiration
c. Increases in the rate ofrespiration d. Noneof the above
2. Increasing thoracic volume will most likely results in

4. Which of the following is most correct for acid-basedisturbance?
a. Respiratory acidosis may results from defect in ventilation andperfusion
b. Compensatory mechanism for respiratory acidosis ishypoventilation
c. Respiratory alkalosis results from hypercapnea
d. Compensatory mechanism for respiratory alkalosis ishyperventilation

a. Compliance is inversely proportional to the amount of surfactanton the alveolar surface
b. Alveolar surface tension is proportional to the amount ofsurfactant
c. Compliance is proportional to the surface tension
d. Alveolar ventilation is equal to the tidal volume corrected fordead space times the breathing frequency
