Final answer:
Consulting with the healthcare provider is indicated when blood is oozing from the venipuncture site.
Step-by-step explanation:
Consulting with the healthcare provider before obtaining and administering platelets is indicated when there is a potential risk or complication associated with the transfusion. In this case, the nurse should consult with the healthcare provider because blood is oozing from the venipuncture site, indicating ongoing bleeding. This suggests that platelet transfusion may not effectively control the bleeding and further interventions may be required.
