50. In which of the following would arterial PCO 2 be decreased compared to normal? (Hint: think about the changes in ventilation that occur and what increased / decreased ventilation does to arterial PCO 2 .) A) metabolic alkalosis B) metabolic acidosis Respiratory system can “blow off CO 2 which, in effect, is getting rid of acid. So you would do this in acidosis (too much acid in the body). Increasing ventilation to blow off CO 2 means that PCO 2 of arterial blood will decrease. Increased ventilation brings in more fresh air and decreases alveolar and arterial PCO 2 . Answer is B.

Unformatted text preview: Notes) A) is respiratory acidosis B) would cause decreased stimulation of peripheral chemoreceptors C) would cause increased stimulation of peripheral chemoreceptors D) causes the kidneys to excrete a more alkaline urine E) A and C Respiratory acidosis is caused by increased CO 2 (any acidosis NOT due to CO 2 is metabolic acidosis - which is what is described in the question). Remember from Respiratory Lectures, that increased H + not due to CO 2 will stimulate the peripheral chemoreceptors. Urine would be more acidic - person is in acidosis, so want to get rid of acid (get rid of more H + in the urine, so the urine would be more acidic, not more alkaline). Answer is C....

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
