Final answer:
The highest priority nursing intervention for a patient admitted for an inevitable abortion at 15 weeks and returning from surgery is to monitor for excessive bleeding to prevent complications like postpartum hemorrhage.
Step-by-step explanation:
After a patient returns from surgery for an inevitable abortion at 15 weeks gestation, the nursing intervention with the highest priority would be C) Monitor for excessive bleeding. This is critical because the risk of postpartum hemorrhage is substantial after an abortion procedure, with incomplete expulsion of the placenta or fetal membranes being potential causes for concern. While other interventions like offering emotional support, administering pain medication, and encouraging ambulation are important, they follow the immediate physical health needs of the patient. Excessive bleeding must be addressed promptly to prevent further complications and ensure the safety and wellbeing of the patient.
It is crucial to also ensure the involved medical team, including the surgeon, nurse, and anesthesia professional, is aware of the patient's postoperative condition and any concerns that may arise during recovery. The continuous reevaluation of vital signs and patient status will guide further interventions.
