When inspecting the client's skin, the nurse observes several areas of ecchymosis on the trunk and extremities. Which information in the client's history requires additional follow-up by the nurse?

A. While dental surgery can result in localized bruising or bleeding, it is unlikely to cause widespread ecchymosis on the trunk and extremities. This finding would not typically require additional follow-up for the cause of ecchymosis unless there were other signs of a bleeding disorder. B. A gluten-free diet is not associated with increased bruising or bleeding. Therefore, this aspect of the client's history does not necessitate further investigation in relation to the observed ecchymosis. C. Taking an oral anticoagulant is directly related to an increased risk of bleeding and bruising, which can manifest as ecchymosis. The nurse should follow up on this information to assess the adequacy of anticoagulation and whether the medication dosage needs adjustment or if there is a potential overdose. D. Working in a daycare center does not correlate with the development of ecchymosis and is not typically associated with any condition that would cause widespread bruising. This does not require further follow-up in the context of the observed skin findings.
