In a patient at 15 weeks' gestation with dark brown vaginal bleeding, frequent nausea and vomiting, blood pressure 142/98 mm Hg, and fundal height 19 cm, which prescription is most important for the nurse to request from the primary care provider?

In a patient at 15 weeks' gestation with dark brown vaginal bleeding, frequent nausea and vomiting, blood pressure 142/98 mm Hg, and fundal height 19 cm, which prescription is most important for the nurse to request from the primary care provider?

• A. Bed rest
• B. Stat ultrasound
• C. Antihypertensive medication
• D. Serial hematocrit

Answer: (B)

When vaginal bleeding in early pregnancy is accompanied by a fundal height that seems larger than expected for gestational age, the most urgent step is to rapidly determine what is going on inside the uterus. A stat ultrasound provides the quickest, most informative look at viability, location, and dating. An urgent ultrasound can confirm that the pregnancy is intrauterine and show whether a fetal heartbeat is present, which helps distinguish viable pregnancy from a miscarriage or a potential ectopic pregnancy. It also helps determine gestational age and assess placental location, both of which explain why the fundal height appears higher than dates. In addition, ultrasound can reveal signs suggestive of molar pregnancy (for example, an abnormal uterus size for gestational age with bleeding), guiding immediate management. Other options don’t address the underlying need as directly. Bed rest has limited evidence for improving outcomes in bleeding episodes and won’t clarify the diagnosis. Antihypertensive medication would be considered if severe or persistent hypertension were present, but this BP finding alone doesn’t resolve the bleeding risk or determine location and viability. Serial hematocrit may help monitor ongoing blood loss but won’t identify the cause or location of the bleeding. The ultrasound finding is what guides urgent management.
