Step-by-step explanation:
A hemoglobin level of 6.0 mg/dL indicates a low hemoglobin level, which is commonly seen in conditions such as anemia. Anemia is a disorder in which the blood has an inadequate volume of red blood cells, reducing the amount of oxygen that the blood can carry. Symptoms of anemia can include fatigue, shortness of breath, and pale skin. In this case, Amy's symptoms of tiredness, shortness of breath, and increased sleep, along with her low hemoglobin level, suggest the possibility of anemia.
