Which popular herb is used for its possible benefit on the immune system?

A. Fish oil: While fish oil has some evidence for reducing inflammation, the evidence for its effectiveness in treating arthritis is mixed.

B. DHEA: DHEA is a hormone and there is not enough evidence to support its use for arthritis.

C. Garlic and soy: While garlic and soy have some general health benefits, there is no strong evidence they are effective for treating arthritis.

D. Chondroitin and glucosamine: These supplements are the most studied option for arthritis and some studies have shown they may provide modest pain relief, although the evidence is not conclusive.

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
