A16-year-old involved in a motor vehicle accident is brought via ambulance to the emergency room you work at. she needs an emergency blood transfusion. her mother, a devout jehovah's witness, refuses to give permission for her daughter to receive blood products because it goes against her faith.

The rejection of blood transfusions due to their religious believes can cause an ethical dilemma. The physician's duty is to try to discuss with patients about this subject, but still be respectful. The physician should provide optimal treatments such as use of prohaemostatic agents and interventions to reduce blood loss and hence, reduce the risk of subsequent need for blood transfusion.

the correct answer is b

hypoxemia refers to a below usual concentration of oxygen in the blood, mainly in the arteries. hypoxemia is an indication of an issue associated with circulation or breathing and may lead to various symptoms like shortness of breath.  

the condition is identified by determining the level of oxygen in the blood sample obtained from an artery. it can also be predicted by determining the oxygen saturation of the blood with the application of a pulse oximeter.  

the normal arterial oxygen is about 75 to 100 mm hg. the values underneath 60 mm hg is generally considered with the requirement for supplemental oxygen. the normal pulse oximeter readings generally range between 95 to 100 percent. the values under 90 percent are regarded as low.  

in the given case, the oxygen saturation is measured at 93 percent, hence, there is no need to administer oxygen, that is, one should withhold oxygen.
