Rationale 1: Breathing might be easier, but this is an additional benefit, not the primary reason.
Rationale 2: As blood volume is lost, hemoglobin is lost. Oxygen is carried from the respiratory system to the cells by hemoglobin in the blood.
Rationale 3: The patient might be more comfortable, but this is an additional benefit not the primary reason.
Rationale 4: The risk of shock might be decreased through oxygen administration, but this is an additional benefit not the primary reason.
