Question

17. You want to climb Mt. Everest. You don’t have enough vacation time, however, to stay at base camp for the full recommended time. Base camp is at a higher elevation than sea level. Will this be a problem? a. Yes. Your liver will detect the decreased partial pressure of oxygen and stimulate the release of renin causing hypertension. b. Yes. Your body will have lower PO2, but the kidney will not have sufficient time to trigger an increase in RBC production. c. No. Your kidney will detect the decrease in PO2 and immediately release erythropoietin, causing rapid increased RBC production. d. No. Your peripheral tissues will detect the lowered PO2 and switch to fermentation pathways. e. No. There’s no change in PO2 at higher elevations. Time at base camp is to acclimate to increased partial pressure of nitrogen.
