The nurse is assessing an immobile patient for deep vein thromboses (DVTs) . Which action will the nurse take?

A) Remove elastic stockings every 4 hours.
B) Measure the calf circumference of both legs.
C) Lightly rub the lower leg for redness and tenderness.
D) Dorsiflex the foot while assessing for patient discomfort.

Measure bilateral calf circumference and record it daily as an assessment for DVT. Unilateral increases in calf circumference are an early indication of thrombosis. Homan's sign, or calf pain on dorsiflexion of the foot, is no longer a reliable indicator in assessing for DVT, and it is present in other conditions. Remove the patient's elastic stockings and/or sequential compression devices (SCDs) every 8 hours, and observe the calves for redness, warmth, and tenderness. Instruct the family, patient, and all health care personnel not to massage the area because of the danger of dislodging the thrombus.
