Yes you are correct because your sister is suffering from multidrug-resistant tuberculosis and usually she can spread the tuberculosis through airway.
But the exposure percentage is less compare to non resistant bacteria.
Please take care of your other family members and go to any nearby government or private hospital and go through the priliminary and diagnostic tests as a precautionary measure for your family members.
Please also take care of your sister and complete the course according to the doctor advice.
If you need more details please try to consult me online I will explain you in detail.
