Jacquemier’s sign is?
**Core Concept**
Jacquemier's sign is a clinical sign observed during a pelvic examination, particularly in cases of pregnancy. It refers to the bluish discoloration of the cervix due to the increased vascularity and venous congestion in the cervix during early pregnancy.
**Why the Correct Answer is Right**
The bluish discoloration of the cervix is caused by the increased blood flow and venous congestion in the cervix. This is due to the hormonal changes and increased vascularity associated with early pregnancy. The cervix becomes more vascular and engorged, leading to the visible bluish discoloration.
**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect as it does not accurately describe Jacquemier's sign. Jacquemier's sign is specifically related to the bluish discoloration of the cervix, not the vaginal wall.
**Option B:** This option is incorrect as it is a different clinical sign altogether. Goodell's sign is the softening of the cervix, which is a different early sign of pregnancy.
**Option C:** This option is incorrect as it refers to a different clinical sign. Chadwick's sign is the bluish discoloration of the vulva and vagina, also an early sign of pregnancy, but not the same as Jacquemier's sign.
**Clinical Pearl / High-Yield Fact**
Jacquemier's sign is an important clinical sign in the early detection of pregnancy. It is one of the four classic signs of early pregnancy, along with Goodell's sign, Chadwick's sign, and Hegar's sign.
**Correct Answer: C. Chadwick's sign is the bluish discoloration of the vulva and vagina, also an early sign of pregnancy, not Jacquemier's sign.
