How does Folic Acid mask Vitamin B12 Deficiency????? KNOW THIS
1.) Folic acid will treat the anemia of B12 deficiency meaning you will no longer have symptoms of anemia.
2.) This is BAD because B12 deficiency can lead to CNS effects (like ↓ muscle tone, impaired concentration, muscle weakness, dizziness, syncope, etc.) & which can be IRREVERSIBLE if the deficiency is prolonged
Aspirin MOA
binds to COX-1 to prevent the production of TXA2 (Thromboxine-A2)
- irreversibly binds COX-1
Vitamin K Antagonists MOA
- warfarin prevents the liver from making new functional clotting factors by inhibiting Vitamin K Epoxide Reductase (prevents the body from recycling Vitamin K)
- ↓ activity of Factors II, VII, IX, X, Protein C, & Protein S

↑ vitamin K intake
What do you do if a patient comes into a clinic on Warfarin with an INR of 8 & is actively bleeding? Would giving Vitamin K help?
NO, because vitamin K takes 5-7 days to start working. Instead give the patient fresh frozen plasma
Specific Xa Inhibitor Drug MOA
binds & inhibits Xa (10-A) factor in the blood
If an individual presents to a clinic actively bleeding & is on a specific Xa inhibitor, should plasma or whole blood be given?
No, the patient’s body will continue to inhibit clotting factors that are being prouduced
