Final answer:
e. A and D taken together. The correct sign of anemia is a low RBC count or low hemoglobin levels.
Step-by-step explanation:
Anemia is a condition characterized by a deficiency in the number of red blood cells (RBCs) or hemoglobin. The options given are:
- a. 3.5 million RBC - This value is below the normal range (4.2-6.1 million) and could indicate anemia.
- b. 10,000 WBC - This value represents the white blood cell count and is unrelated to anemia.
- c. 400,000 platelets - This value represents the platelet count and is unrelated to anemia.
- d. 5.5 million RBC - This value is within the normal range and does not indicate anemia.
- e. A and D taken together - Since option a (3.5 million RBC) is a sign of anemia, selecting both options a and d would be the correct answer.
Therefore, the correct option is e. A and D taken together.
