Which action supports evaluation and treatment of suspected lower-extremity deep vein thrombosis?

• A. Initiate IV Heparin therapy
• B. Massage the area of warmth
• C. Place a warm compress on the leg
• D. Obtain lab studies for aPTT, PT, and INR

Answer: (A)

When a deep vein thrombosis is suspected, the priority is rapid anticoagulation to prevent clot growth and possible pulmonary embolism. Initiating IV heparin provides immediate anticoagulation and can be started while imaging is arranged to confirm the diagnosis. Heparin is preferred in pregnancy because it does not cross the placenta and can be closely monitored and reversed if needed. The dose is guided by the aPTT to keep therapy at a therapeutic level, balancing risk and benefit. Avoid massaging or applying a warm compress to the affected leg because physical manipulation or heat can disrupt the clot and increase the risk of embolization. Lab tests like aPTT, PT, and INR are useful for monitoring anticoagulation and bleeding risk, not for treating DVT or confirming its presence.
