The Nurse Identifies a Nursing Diagnosis of Risk for Altered

The nurse identifies a nursing diagnosis of risk for altered peripheral tissue perfusion related to bypass graft thrombosis for a patient following an abdominal aneurysm repair. An appropriate intervention to prevent this problem in the immediate postoperative period is to

A) use a cooling blanket to maintain the patient's temperature within a normal range to prevent hypercoagulability.
B) place the patient in Trendelenburg position to reduce pressure at the suture line and prevent leaking of blood at the site.
C) administer IV fluids at a rate to keep the arterial BP within a normal range.
D) perform passive range-of-motion (ROM) exercises to the legs hourly to promote venous return.
