Which condition is most concerning given persistent nausea and vomiting with weight loss and signs of dehydration in a pregnant client at 18 weeks?

• A. Hyperemesis gravidarum
• B. Gestational diabetes
• C. Preeclampsia
• D. Ectopic pregnancy

Answer: (A)

Persistent nausea with weight loss and signs of dehydration in mid-pregnancy signals a severe form of nausea called hyperemesis gravidarum. This condition goes beyond common morning sickness and can lead to significant fluid loss, electrolyte imbalances, and even ketosis, which endangers both mother and fetus if not addressed promptly. That risk makes it the most concerning scenario here, prompting evaluation for dehydration, labs to check electrolytes and ketones, and often hospital-based treatment with IV fluids, antiemetics, and nutritional support. Gestational diabetes can develop later and is driven by elevated glucose levels, not primarily by vomiting or dehydration. Preeclampsia typically presents after 20 weeks with new-onset hypertension and proteinuria, rather than vomiting and dehydration being the main issues. An ectopic pregnancy is a pregnancy complication usually occurring early with abdominal pain and possible bleeding, not a late-petal presentation at 18 weeks with persistent vomiting and dehydration.
