A.
To determine: Thecause of woman’s high PCO2 and low PO2.
Introduction. The restrictive disorders like chronic obstructive pulmonary disorder (COPD), asthma and many more results in the decrease in the speed of the airflow through the airway because the air passage is blocked by the accumulation of mucus or cellular buildup.
B.
To determine: The reason hypoventilation almost causes an increase in PCO2.
Introduction. The respiratory tract is the long tube that extends from the nose to the lungs. The inner lining of the respiratory tract is lined by mucosa that secrets mucous for easy expansion and contraction of the tube and also to trap the dust and foreign particles in the mucous membrane.
C.
To determine: The reason why the increase in PO2 to 90 mm Hg with the institution of oxygen therapy.
Introduction. Asthma and asthma-related symptoms occur more frequently in urban areas than in rural areas, and this difference is correlated with environmental risk exposures and access to healthcare. The environmental risk factors such as dust mites,high levels of vehicle emissions, and a westernized lifestyleare more prevalent in the urban areas than the rural areas.

She recently returned from a trip to sub-Saharan Africa, where she did not take malaria prophylaxis. On examination, she is febrile (39.8°C/103.6°F) and hypotensive. Laboratory studies reveal hemoglobin of 8.0 g/dL, platelet count of 50,000/μL, and evidence of hemoglobinuria. A peripheral blood smear shows ring forms and banana-shaped gametocytes. Which of the following Plasmodium species is most likely responsible for her severe symptoms? A. Plasmodium vivax B. Plasmodium ovale C. Plasmodium malariae D. Plasmodium falciparumarrow_forward
