A nurse is assessing a client who is taking combination oral contraceptives. Which of the following findings should the nurse report to the provider immediately?

A. Nausea: Mild nausea is a common side effect of combination oral contraceptives and usually resolves over time. It is typically managed conservatively and does not require immediate reporting. B. Cramps: Mild abdominal cramps can occur with oral contraceptive use and are generally not indicative of serious complications. They are monitored but do not warrant urgent intervention. C. Abdominal bloating: Mild bloating is a common, non-urgent side effect of oral contraceptives. While it should be documented, it is not a signal for immediate action. D. Leg tenderness: Unilateral leg tenderness may indicate deep vein thrombosis, a potentially life-threatening complication of oral contraceptives due to increased risk of thromboembolism. Immediate reporting to the provider is required for prompt assessment and intervention.
