Final answer:
The nurse should report a platelet count of 78,000/mm3 to the provider as it indicates thrombocytopenia, a low platelet count. Thrombocytopenia is a common side effect of chemotherapy and can lead to an increased risk of bleeding.
Step-by-step explanation:
The nurse should report a platelet count of 78,000/mm3 to the provider. This value is below the normal range (150,000-400,000/mm3) and indicates thrombocytopenia, a low platelet count. Thrombocytopenia is a common side effect of chemotherapy and can lead to an increased risk of bleeding. The provider may need to adjust the treatment plan or prescribe interventions to prevent bleeding complications.
