A patient who has received heparin after previous surgeries will be given enoxaparin sodium (Lovenox) after knee-replacement surgery. The patient asks how this drug is different from heparin. The nurse will explain that enoxaparin
a. decreases the need for laboratory tests.
b. has a shorter half-life than heparin.
c. increases the risk of hemorrhage.
d. may be taken orally instead of subcutaneously.
ANS: A
Enoxaparin is a low–molecular-weight heparin, which produces more stable responses at lower doses, thus reducing the need for frequent lab monitoring. It has a longer half-life than heparin. It decreases the risk of hemorrhage because it is more stable at lower doses. It is given subcutaneously.
