When a person suffers a stroke, it is initially caused by damage to a) circulatory system b) nervous system c)pulmonary system

The correct answer would be a) circulatory system.

A stroke is primarily caused due to reduced or interrupted supply of blood to the brain.

The blood supply is usually reduced as a result of blockage or bursting of an artery carrying blood to the brain.

Consequently, the brain cells experience a lack of oxygen and nutrients due to which they begin to die.

Thus, stroke is initially caused by damage to the circulatory system.

the answer is otpion c) understanding

he wants to be heard one more time. he wants to be understood. he needs the truth one more time.

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.
