Final answer:
The level of hematocrit and hemoglobin that would indicate no exercise for a person with anemia is a hematocrit < 30% and hemoglobin < 10 g/dL.
Step-by-step explanation:
The level of hematocrit and hemoglobin that would indicate no exercise for a person with anemia is option a) Hematocrit < 30% and Hemoglobin < 10 g/dL.
Hematocrit is the percentage of red blood cells in the total volume of blood. Anemia is characterized by a decrease in the number of red blood cells, resulting in a low hematocrit level. Hemoglobin is a protein in red blood cells that carries oxygen. Anemia often leads to a decrease in hemoglobin levels, indicating a reduced ability to transport oxygen.
Therefore, a person with anemia should avoid exercise if their hematocrit is less than 30% and their hemoglobin is less than 10 g/dL.
