At 18 weeks' gestation, which finding is typically documented during a routine prenatal visit?

• A. Insomnia
• B. Braxton Hicks contractions
• C. Quickening
• D. Fundal height approximately 18 cm

Answer: (D)

Measuring fundal height is how clinicians track fetal growth and confirm gestational dating during routine prenatal visits. At about 18 weeks, the distance from the pubic symphysis to the top of the uterus (the fundus) is typically around 18 centimeters, reflecting the gestational age in weeks. This objective measurement helps verify that the pregnancy is progressing on track. Other signs like quickening (fetal movement) or Braxton Hicks contractions can occur around this time, but they are more variable and not used as the standard documentation of gestational age at this specific visit. Insomnia is a common symptom but not a measurement used to assess fetal development.
