Answer:
The patient will have increased blood flow and decreased blood viscosity.
Step-by-step explanation:
Thinning blood makes it, for lack of better term, thinner. This means it must have a lower viscosity. (For examples of viscosity, think of pouring out a glass of water versus a glass of maple syrup. The syrup has a much higher viscosity, and will take longer.)
As demonstrated in the above example, liquids with lower viscosity flow faster. This means the patient's blood flow will increase, as it will be easier for the blood to move through capillaries and the heart won't have to push as hard to move the blood through the body.
These results correspond with answer B or D, which, at the time of this answer, are identical. Whichever answer states increased blood flow and decreased viscosity is correct.
