Appeared in: NCL (MP) Nursing Officer - 2020

Explanation

Chadwick's sign refers to the characteristic violet or bluish discoloration of the vaginal mucous membrane, cervix, and vulva.
It is considered an early, presumptive sign of pregnancy, typically appearing around the 6th to 8th week of gestation.
The underlying cause is hyperemia, which is an increase in blood flow to the pelvic organs, driven by elevated estrogen levels.

Option A: Hegar's sign is a change in the consistency (softening) of the lower uterine segment (isthmus), not a change in color.
Option B: Goodell's sign is the softening of the cervix itself, often compared to the consistency of lips. It is a tactile sign, not a visual color change.
Option D: Osiander's sign is the detection of a palpable pulsation in the lateral vaginal fornices. It is a tactile sign related to increased blood flow, not a visual discoloration.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Presumptive Signs of Pregnancy as background academic context rather than a clinical decision trigger.
Recognizing presumptive signs like Chadwick's sign is a fundamental skill for nurses in early pregnancy assessment and patient counseling.
While not definitive proof of pregnancy, the presence of these signs prompts further investigation, such as hCG testing and ultrasound, to confirm the diagnosis.
Patient education is crucial. A nurse should explain that these changes are normal physiological responses to pregnancy hormones.

How to Approach the Question

First, identify the key clinical finding described in the question stem: "violet or bluish discoloration of the vaginal mucous membrane."
Recognize that this is a factual recall question testing your knowledge of the specific signs of pregnancy.
Systematically review each option and recall its definition.
Differentiate between the signs based on the type of change: Chadwick's sign is a color change, Goodell's and Hegar's signs are changes in consistency (softening), and Osiander's sign is a palpable pulsation.
Match the description of "bluish discoloration" with the correct term, which is Chadwick's sign.
