In suspected deep vein thrombosis, which action is contraindicated because it could dislodge the clot?

• A. Ambulate the client around the room
• B. Assess Homans' sign
• C. Apply intermittent warm, moist soaks to the leg
• D. Elevate the affected limb

Answer: (B)

When deep vein thrombosis is suspected, avoid any maneuver that could move or dislodge the clot. Assessing Homans' sign means dorsiflexing the foot to elicit pain, which can physically displace a thrombus and potentially precipitate a pulmonary embolism; for this reason that action is contraindicated. Elevating the affected limb is a common, safer measure to improve venous return, whereas the other options do not specifically involve applying a maneuver that could loosen the clot.
