A nurse is providing teaching to a client who is at 6 weeks of gestation about manifestations of potential complications during pregnancy. For which of the following manifestations should the nurse instruct the client to notify the provider?

Rationale: A. Swelling of gums (gingivitis) is common in pregnancy due to hormonal changes and increased blood flow; it is not a danger sign. B. Burning during urination indicates a urinary tract infection (UTI). Untreated UTIs increase the risk of pyelonephritis and preterm labor, so prompt medical evaluation and antibiotics are necessary. C. White vaginal discharge (leukorrhea) is a normal physiological response to hormonal changes that maintain vaginal acidity; it does not require medical attention unless accompanied by odor, itching, or color changes. D. Occasional nosebleeds are common in pregnancy due to increased vascularity and nasal mucosal congestion caused by elevated estrogen levels.
