Final answer:
An expectant mother in the 1st trimester who presents with active bleeding and anemia during spontaneous abortion should be treated based on the severity of the bleeding and the overall condition of the mother.
Step-by-step explanation:
When an expectant mother in the 1st trimester presents with active bleeding and anemia during a spontaneous abortion, she should be treated based on the severity of the bleeding and her overall condition. In some cases, conservative management may be appropriate with close monitoring and supportive care to allow the body to naturally expel the pregnancy tissue.
However, if the bleeding is severe or the mother is experiencing complications like hypovolemic shock, medical or surgical intervention may be necessary.
