Which statement about normal menstrual flow is true?

• A. Flow should require frequent tampon or pad changes.
• B. Menstrual flow duration is fixed at 3–5 days.
• C. Cycle can be as long as 40 days.
• D. Flow should not require frequent tampon/pad changes and should not cause anemia.

Answer: (D)

The main idea here is that normal menstrual flow is something you can manage with usual hygiene products and it should not lead to iron deficiency anemia. A flow that doesn’t require frequent changes reflects typical blood loss—enough to handle with standard tampons or pads without needing hourly changes. At the same time, it shouldn’t be so heavy that it gradually depletes iron stores and causes anemia. So the statement that flow should not require frequent changes and should not cause anemia best captures what is expected in a normal menstrual period. In contrast, needing frequent changes suggests heavier-than-normal flow, which is not typical. Saying the duration of flow is fixed at 3–5 days ignores the natural variation in how long periods last. And claiming that the cycle can be as long as 40 days speaks to cycle length, not the amount of flow or anemia risk, so it doesn’t address the normal flow characteristics as directly.
