The answer and the reasoning

B. Hyperemesis gravidarum

Hyperemesis gravidarum is severe pregnancy-related vomiting causing weight loss, dehydration, ketosis, or electrolyte disturbance. Other medical and surgical causes of vomiting should also be assessed.

Option by option

  • A. Normal morning sickness only

    Typical morning sickness does not usually cause marked dehydration and ketonuria.

  • B. Hyperemesis gravidarum (correct)

    Correct. Ketosis and dehydration distinguish hyperemesis from mild nausea and vomiting.

  • C. Pre-eclampsia

    Pre-eclampsia occurs after 20 weeks and is defined by hypertension with associated features.

  • D. Acute appendicitis

    Appendicitis causes evolving abdominal tenderness and systemic inflammatory findings.
