Final answer:
The nurse should encourage the patient to frequently ambulate and to elevate the legs postoperatively after vein ligation and stripping to promote circulation and reduce swelling, therefore preventing the risks associated with varicose veins treatment.
Step-by-step explanation:
A nurse is caring for a patient who is postoperative following vein ligation and stripping for varicose veins. Among the actions listed, the nurse should encourage the patient to ambulate frequently (Option A) and to elevate the patient's legs (Option D). Frequent ambulation helps improve circulation and prevents blood from pooling in the legs, which can reduce the risk of developing a thrombus or clot. Elevation of the legs assists in decreasing edema and promoting venous return to the heart.
While applying warm compresses may be appropriate for certain conditions, it is not specifically indicated for postoperative care following vein ligation and stripping, as warmth can increase swelling in the area. Opioid analgesics should only be used if the pain level necessitates such strong medication, and this decision should be based on a physician's order and assessment of the patient’s pain. Therefore, frequent ambulation and leg elevation are the correct actions to take in this scenario.
