True or False: Enoxaparin dosage is directed by monitoring aPTT levels.
 
  Explain your answer.

Question 2

The order for the enoxaparin reads: Enoxaparin 70 mg every 12 hours subcut. L.J. is 5 ft, 6 in tall and weighs 156 lb.
 
  Is this dose appropriate?

Answer to Question 1

False. Low-molecular-weight heparins, such as enoxaparin, do not require any laboratory monitoring
because of their greater affinity for factor Xa (compared with heparin, which is monitored by aPTT
levels when given intravenously).

Answer to Question 2

The appropriate dose for enoxaparin is 1 mg/kg. 154 lb = 70 kg.
1 mg/kg  70 kg = 70 mg; therefore the ordered dose of 70 mg is appropriate for L.J.
