Please find the answers and explanations below: Answer 1: According to the arterial blood gas data, it can be seen the PO2 and PCO2 of Charles are within normal ranges but PCO and PN2 are very high. This clearly suggests toxic accumulation of these gases in his blood probably due to partial combustion of kerosene oil. Thus option d seems most correct. Answer 8: Option c is correct. Toxicity of CO and N2 has not changed the PO2 and PCO2 values of Charles but PCO and PN2 are exceedingly high. Since CO and N2 have higher affinitiy for hemoglobin binding than O2, they will prevent transport of oxygen from the blood to cells and the exchange of CO2 for O2. Thus, ventilation will be affected in later stages but fundamentally, the transport of gases will be highly and directly impaired. Answer 9: Option c is correct. Emphysema is a respiratory disease where toxic chemicals are entrapped in the alveolar/arterial blood gas and prevent further transport of gases to different cells of the body. It primarily occurs due to tobacco smoke and lead to chronic obstructive pulmonary disorder. The condition of Charles is very much similar to it. Answer 10: Option d is correct: Increasing the blood pCO2 levels will further dampen the respiratory system and impair the medical condition of Charles. He should be given general alkalosis of blood along with a gaseous mixture of high oxygen content to sustain life.

Answer 1: According to the arterial blood gas data, it can be seen the PO2 and PCO2 of Charles
are within normal ranges but PCO and PN2 are very high. This clearly suggests toxic
accumulation of these gases in his blood probably due to partial combustion of kerosene oil.
Thus option d seems most correct.
Answer 8: Option c is correct. Toxicity of CO and N2 has not changed the PO2 and PCO2 values
of Charles but PCO and PN2 are exceedingly high. Since CO and N2 have higher affinitiy for
hemoglobin binding than O2, they will prevent transport of oxygen from the blood to cells and
the exchange of CO2 for O2. Thus, ventilation will be affected in later stages but fundamentally,
the transport of gases will be highly and directly impaired.
Answer 9: Option c is correct. Emphysema is a respiratory disease where toxic chemicals are
entrapped in the alveolar/arterial blood gas and prevent further transport of gases to different
cells of the body. It primarily occurs due to tobacco smoke and lead to chronic obstructive
pulmonary disorder. The condition of Charles is very much similar to it.
Answer 10: Option d is correct: Increasing the blood pCO2 levels will further dampen the
respiratory system and impair the medical condition of Charles. He should be given general
