A patient is staying in a cabin at an altitude of 5,000 feet. After 5 days his respiratory rate is elevated and his arterial PCO2 is decreased. What other changes would be present?
Select Your Answer:
The decreased barometric pressure at high altitude causes arterial hypoxemia.
The patient compensates by increasing the respiratory rate, which reduces PCO2 and results in respiratory alkalosis.
The kidneys compensate by increasing excretion of HCO3 to balance the respiratory losses of bicarbonate.
