A pharmacist is preparing an order of heparin for a new patient. The patient is most likely suffering from a case of anemia. iron deficiency. hemophilia. thrombosis.

Explanation:

First, let's figure out what heparin is.

It is a prescription, injectable drug that is a blood thinner. It helps to prevent the blood from clotting.

Now, let's analyze each disease and see which one would need heparin.

Anemia

The body lacks sufficient red blood cells and hemoglobin, so oxygen delivery to cells isn't efficient. This wouldn't need a blood thinner.

Iron deficiency

This is linked to anemia. The body doesn't have enough iron or red blood cells, and anemia ensues.

Hemophilia

A genetic disease where blood can't clot. A blood thinner is meant to prevent blood clots and the blood already can't do that. It would only make the problem worse.

Thrombosis

Involves the clotting of blood, which blocks the blood vessels. This would need a blood thinner to prevent the clots.

The best answer choice is thrombosis.
