The antepartum clinic nurse is triaging telephone messages from four clients. Which call should the nurse return first?

Choice A rationaleFrequent urination is common in early pregnancy due to hormonal changes and increased blood flow to the pelvic area. It is not typically a sign of an urgent complication requiring immediate attention.Choice B rationaleMenstrual-like cramps at 25 weeks gestation could indicate preterm labor, which is a potential emergency. Prompt evaluation is necessary to ensure the health and safety of both the mother and the fetus.Choice C rationaleLeg cramps while reclining are common in later stages of pregnancy due to changes in circulation and increased pressure on the veins. They are usually not a sign of an urgent complication.Choice D rationaleA reddened, pruritic lower abdominal rash could indicate a skin condition or allergic reaction, but it is generally not an urgent complication during pregnancy unless accompanied by other severe symptoms.
