Final answer:
Nurses might intervene for a woman at risk for thrombus and not ready to ambulate by using antiembolic stockings and/or sequential compression device boots, having her perform foot, ankle, and leg movements, and encouraging her to sit in a chair.
Step-by-step explanation:
The interventions that nurses might use for a woman at risk for thrombus and not ready to ambulate include putting her in antiembolic stockings (TED hose) and/or sequential compression device (SCD) boots, having her flex, extend, and rotate her feet, ankles, and legs, and having her sit in a chair. However, they should not notify the physician immediately if a positive Homans' sign occurs, as this can potentially dislodge the thrombus and lead to further complications.
