The priority nursing action is to monitor the biopsy site for active bleeding or hematoma formation. Apply a pressure dressing and ensure the patient maintains bed rest for the prescribed period, typically 30 to 60 minutes, lying on the site to promote hemostasis.
Vital sign changes like hypotension and tachycardia are late signs of hemorrhage. Direct site assessment every 15 minutes for the first hour is critical for early detection and intervention.
