What is a significant advantage of enoxaparin over unfractionated heparin?

  1. No need for laboratory monitoring

  2. Higher risk of thrombosis

  3. It is administered orally

  4. Less effective in preventing blood clots

The correct answer is: No need for laboratory monitoring

Enoxaparin, a low molecular weight heparin, has a significant advantage over unfractionated heparin in that it does not require laboratory monitoring. Unfractionated heparin, on the other hand, needs to be monitored with frequent blood tests to ensure the correct dosage is administered. Option B, higher risk of thrombosis, is incorrect as enoxaparin is actually more effective at preventing blood clots compared to unfractionated heparin. Option C, administered orally, is incorrect as both enoxaparin and unfractionated heparin are given via injection. Option D, less effective in preventing blood clots, is incorrect as stated earlier, enoxaparin is more effective at preventing blood clots compared to unfractionated heparin.
