The nurse examines a client who is concerned about the amount of menstrual flow she is having. Which finding indicates an abnormality related to the client's current menstruation?

Choice A reason: Odorless, red menstrual blood is considered normal and does not indicate any pathology. It reflects typical menstrual shedding. Choice B reason: Saturating one pad per hour is a clinical indicator of menorrhagia, or excessive menstrual bleeding. This level of blood loss may lead to anemia and warrants further evaluation. Choice C reason: Small clots under 1 cm are generally considered normal during menstruation and do not indicate excessive bleeding or abnormality. Choice D reason: Mild cramping is common during menstruation and is not necessarily indicative of abnormal flow. It is typically due to uterine contractions.
