Question 1 of 5
What is the primary advantage of using low molecular weight heparins (LMWHs) over heparin?
Correct Answer: A
Rationale: The correct answer is A: LMWHs produce a more stable effect on coagulation; thus, fewer lab tests are needed. This is because LMWHs have more predictable pharmacokinetics, resulting in a more consistent anticoagulant effect compared to heparin. This stability allows for fixed dosing without the need for frequent monitoring through lab tests, which is required with heparin due to its variable response.
Choice B is incorrect as LMWHs are not given orally but are administered via subcutaneous injection due to their large molecular size.
Choice C is incorrect because LMWHs have a longer duration of action compared to heparin, making them suitable for once or twice-daily dosing.
Choice D is incorrect as heparin actually possesses greater anticoagulant activity than LMWHs.
