TM, a 57-year-old man, has thrombophlebitis in the right lower leg. IV heparin, 5000 units by bolus, was given. Following the IV bolus, heparin 5000 units given subQ q6h was prescribed. Other therapeutic means to decrease pain and alleviate swelling and redness were also prescribed. An aPTT test was ordered. 1. Was TM's heparin order within the safe daily dosage range? 2. What are the various methods for administering heparin?
A 50-year-old woman develops a small pulmonary embolus 12 hours after undergoing surgical removal of a bunion. Treatment with heparin and warfarin is begun. One day later, heparin is inadvertently discontinued, while warfarin is continued. Twenty-four hours later, she develops another pulmonary embolus. Which of the following best explains the second embolic episode? A) Factor VII (proconvertin) synthesis was poorly inhibited by warfarin B) Rebound synthesis of coagulation factors occurred when the heparin was stopped C) Residual carboxylated factor I (prothrombin) permitted thrombus formation D) Warfarin initially stimulated protein C E) Warfarin initially stimulated vitamin K synthesis to render this patient hypercoagulable
