What is the primary advantage of using low molecular weight heparins (LMWHs) over heparin?

LMWHs produce a more stable effect on coagulation; thus, fewer lab tests are needed.

LMWHs may be given by the oral route

LMWHs have a short duration of action

LMWHs possess greater anticoagulant activity

Answer and Explanation

The Correct Answer is A

A. LMWHs produce a more stable effect on coagulation; thus, fewer lab tests are needed: Correct LMWHs have a more predictable anticoagulant response compared to unfractionated heparin, resulting in a more stable effect on coagulation. Because of their predictable response, routine monitoring of coagulation parameters, such as activated partial thromboplastin time (aPTT), is typically not required with LMWH therapy, unlike with unfractionated heparin.

B. LMWHs may be given by the oral route: Incorrect. LMWHs are administered by the subcutaneous route.

C. LMWHs have a short duration of action: Incorrect. LMWHs have a longer duration of action compared to unfractionated heparin.

D. LMWHs possess greater anticoagulant activity: incorrect. LMWHs generally have less potent anticoagulant activity compared to unfractionated heparin, but their more predictable response and longer half-life make them advantageous in many clinical scenario

Correct Answer is C

Explanation

A. Ferrous sulfate: This is an iron supplement and wouldn't be used to reverse warfarin's anticoagulant effect.

B. Prednisone: This is a steroid medication used for various inflammatory conditions and wouldn't be used to address excessive blood thinning.

C. Vitamin K: Vitamin K is the antidote for warfarin poisoning or excessive anticoagulation. By providing vitamin K, the body can resume producing clotting factors, counteracting warfarin's effect.

D. Heparin: This is another blood thinner medication. While it can be used in specific situations, it wouldn't be the first choice to reverse warfarin's effect because it adds another layer of anticoagulation, which could be risky.

A. Echinacea B. Garlic C. Ginseng D. Valerian E. Ginger

Correct Answer is ["A","B","C","D","E"]

Explanation

A. Echinacea: Potential anticoagulant effects may increase the risk of bleeding when combined with warfarin.

B. Garlic: Garlic supplements have anticoagulant properties, which can increase the risk of bleeding when combined with warfarin.

C. Ginseng: Ginseng has antiplatelet effects, increasing the risk of bleeding when combined with warfarin.

D. Valerian: Valerian may interact with warfarin, potentially increasing the risk of bleeding.

E. Ginger: Ginger has antiplatelet effects, which can increase the risk of bleeding when combined with warfarin.
