Violet blue discoloration of vaginal membrane is?

Appeared in: AIIMS Bhuvneshwar NO- 2018

Explanation

Jacquemier's sign, which is the characteristic violet-blue discoloration of the vaginal mucous membrane.
This sign, also known as Chadwick's sign, is a probable indicator of early pregnancy.
It is caused by hyperemia, which is an increase in blood flow to the pelvic organs, stimulated by rising estrogen levels.
This sign typically becomes apparent around the 6th to 8th week of gestation.

Option A: Osiander's sign is a tactile sign, not a visual one. It refers to the increased pulsation felt in the lateral vaginal fornices due to increased blood flow through the uterine artery.
Option C: Hegar's sign is the softening of the uterine isthmus (the lower part of the uterus). It is detected by a bimanual examination, where the examiner can compress the softened lower uterine segment between the fingers.
Option D: Braxton Hicks sign refers to irregular, usually painless uterine contractions that occur intermittently throughout pregnancy. They do not cause cervical dilation and are not related to vaginal discoloration.

It is important for the nurse to differentiate between presumptive, probable, and positive signs to avoid misdiagnosis and provide accurate patient education.
