A nurse is providing teaching to a client who is at 14 weeks of gestation about findings to report to the provider. Which of the following findings should the nurse include in the teaching?

A. Faintness upon rising is a common symptom during pregnancy, typically due to orthostatic hypotension, and does not necessarily require reporting unless it is persistent or severe. B. Bleeding gums can occur due to hormonal changes and is usually not a cause for concern. C. Swelling of the face could indicate preeclampsia, a potentially serious condition that should be reported to the provider immediately. D. Urinary frequency is a normal finding during pregnancy and does not need to be reported unless associated with other symptoms such as pain or fever.
