eat.
put on gloves.
pat the test site with a cotton swab.

Explanation:

Washing hands before a self - fingerstick blood glucose test helps prevent contamination of the blood sample and ensures accurate results. Eating can affect blood glucose levels and give inaccurate readings. Putting on gloves is not a standard pre - test requirement for self - testing at home. Patting the test site with a cotton swab is done after the test, not before.

wash her hands
