Which of the following would you NOT expect to happen at high altitude? Question 5Answer a. A drop in atmospheric pO2 b. An increase in ventilation rate c. An increase in arterial pCO2 d. A drop in alveolar pO2 e. A drop in arterial pO2

4) Which of the following will increase alveolar PO2?a) increase in metabolism and no change in alveolar ventilationb) breathing air with 15% oxygen at sea levelc) increase in alveolar ventilation matched by an increase in metabolismd) increased alveolar ventilation with no change in metabolisme) carbon monoxide poisoning

At high altitudes, hypoxia can occur because the percentage of O2 in atmospheric air is decreasedQuestion 16AnswerTrueFalse

As altitude increase the atmospheric pressure decreases.Question 1Answera.Trueb.False

Assertion: A person goes to high altitude and experiences altitude sickness with symptoms like breathing difficulty and heart palpitations.Reason: Due to low atmospheric pressure at high altitude the body does not get sufficient oxygen.In the light of the above statements, choose the correct answer from the options given below.

On ascent to high altitude, there is a marked drop in Hb-O2 saturation, this drop can be explained by: (Select all that are correct. There may be one or more correct options)Group of answer choicesFall in temperature in the atmosphere creates a right ward shift of the Hb-O2 curveDecrease barometric air pressure means the air is less dense and thus the number of O2 molecules inspired with each breath is lessDecrease barometric air pressure decrease O2 partial pressure in the surrounding airPercentage composition of oxygen decreases with altitude, thus less O2 is inspired with each breath
