A patient has been receiving heparin while in the hospital to treat deep vein thromboses and will be discharged home with a prescription for enoxaparin [Lovenox]
The nurse provides teaching for the nursing student who asks about the advantages of enoxaparin over heparin. Which state-ment by the student indicates a need for further teaching? a. "Enoxaparin does not require coagulation monitoring."
b. "Enoxaparin has greater bioavailability than heparin."
c. "Enoxaparin is more cost-effective than heparin."
d. "Enoxaparin may be given using a fixed dosage."
C
Low-molecular-weight (LMW) heparins have higher bioavailability and longer half-lives, so routine coagulation monitoring is not necessary and fixed dosing is possible. LMW heparins are more expensive, however, so this statement indicates a need for further teaching.
