**Question:** Jacquemier's sign in early pregnancy is

A. Positive if the uterus is located above the umbilicus
B. Negative if the uterus is located below the umbilicus
C. Negative if the uterus is located between the umbilicus and the symphysis pubis
D. Positive if the uterus is located below the symphysis pubis

**Correct Answer:** D. Positive if the uterus is located below the symphysis pubis

**Core Concept:** Jacquemier's sign is a clinical test used to assess the position of the gravid uterus in early pregnancy. It helps in determining the stage of gestation and helps in predicting the potential mode of delivery.

**Why the Correct Answer is Right:**

Jacquemier's sign is positive when the uterus is located below the symphysis pubis. This is because in early pregnancy, the gravid uterus enlarges and the uterus descends due to the downward traction exerted by the upwardly growing fetus and the downward pressure of the enlarged uterus on the pelvic floor muscles. As the pregnancy advances, the uterus continues to descend, reaching the perineum in the third trimester.

**Why Each Wrong Option is Incorrect:**

A. This option is incorrect because the uterus does not necessarily remain above the umbilicus in early pregnancy. Its position changes as the pregnancy progresses, and this option is too restrictive.

B. This option is incorrect because a gravid uterus typically descends below the umbilicus in early pregnancy. This option is too specific and does not reflect the normal changes in uterine position during pregnancy.

C. This option is incorrect because the uterus descends below the symphysis pubis in early pregnancy. This option is too restrictive and does not accurately describe the normal uterine position changes during pregnancy.

**Clinical Pearl:** The assessment of uterine position during pregnancy is essential for obstetric care, as it helps in determining the stage of gestation, assessing fetal presentation, and planning the mode of delivery. Regular clinical examination of the gravid uterus is a key part of prenatal care, as it can provide information on fetal well-being and potential delivery complications.
