Which step is a physician most likely to take first with a patient who had family history of heart disease? a. perform blood tests b. give medication c. offer radiation therapy d. perform surgery

Hello!

A physician is most likely to perform blood tests with a patient who has had family history of heart disease. Why?

Option B can be dangerous. It may have no use or they could be allergic to the prescribed drug.
Option C is random. Radiation therapy is used for cancer treatment.
Option D is also not humane. They were not diagnosed with a condition yet. 

math is easy but for slow people it is hard like me
