A nurse is caring for a 58-year-old woman who underwent total abdominal hysterectomy with bilateral salpingo-oophorectomy for ovarian cancer 2 days ago. Which nursing intervention should be the priority?

Early ambulation is the priority to prevent VTE, pneumonia, and ileus in this high-risk postoperative patient. Pain management, breathing exercises, and incision assessment are important but do not address multiple life-threatening complications simultaneously.

Clinical Context & Priority Setting

This patient is in the early postoperative period following a major abdominal cancer surgery. Ovarian cancer creates a profound hypercoagulable state due to the interplay of tumor-derived pro-inflammatory cytokines, expression of tissue factor (TF) on malignant cells, and platelet activation, all of which are compounded by the surgical insult itself ^[1]. In the hierarchy of postoperative needs, preventing a potentially fatal venous thromboembolism (VTE)—encompassing both deep vein thrombosis (DVT) and pulmonary embolism (PE)—takes precedence when multiple interventions are indicated. While pain management, pulmonary toilet, and wound assessment are all essential, they do not address the most immediate life-threatening risk in this specific population.

Why Early Ambulation Is the Priority

The pathophysiologic rationale centers on Virchow's triad: venous stasis, endothelial injury, and hypercoagulability. This patient has all three. The tumor itself drives hypercoagulability through inflammatory cytokines and tissue factor expression, the surgery caused endothelial damage, and postoperative immobility leads to venous stasis ^[1]. Early ambulation directly counteracts venous stasis by activating the calf muscle pump, which propels blood through the deep veins and reduces the risk of thrombus formation. In ovarian cancer patients, where VTE is a "common and potentially severe complication" that can "deteriorate outcomes," mechanical prophylaxis through mobility is a high-impact, nurse-driven intervention that cannot be deferred ^[1].

Why the Other Options Are Lower Priority

Option 1 (analgesic administration) is important for comfort and to facilitate participation in care, but pain control is a means to an end—it enables ambulation and deep breathing. It is not the terminal priority action itself. Option 2 (deep breathing and incentive spirometry) addresses atelectasis prevention, a standard postoperative concern, but does not mitigate the hypercoagulable threat specific to ovarian cancer. Option 3 (incision assessment) is a routine ongoing assessment, yet wound dehiscence or infection, while serious, does not carry the same immediacy of mortality risk as an acute PE in a patient with a malignancy-driven thrombotic tendency ^[1]. The nurse can assess the wound while preparing the patient for ambulation, but mobilization itself must be the primary action.
