Clinical screening for coagulopathy is considered positive if the patient has which of the following?

A clinical screening for coagulopathy focuses on identifying conditions that affect blood clotting, which can lead to increased bleeding. In this context, a history of heavy periods since menarche is a significant indicator of a possible bleeding disorder or coagulopathy. Heavy menstrual bleeding, also known as menorrhagia, can be a sign of various underlying issues such as von Willebrand disease, platelet function disorders, or clotting factor deficiencies. These conditions can lead to an inability to form stable blood clots, resulting in prolonged bleeding during periods.

While the other options may indicate other health concerns, they do not directly relate to the assessment of coagulation status. A family history of hypertension is more related to cardiovascular health rather than coagulopathy. Chronic migraines may reflect other health issues but are not typically linked to bleeding disorders. Unexplained weight loss can indicate various serious conditions but does not provide specific information about bleeding risk or coagulation issues. Therefore, the history of heavy periods since menarche is the most directly relevant factor for assessing coagulopathy in this scenario.
