Appeared in: RUHS, Jaipur, PB B.Sc Nursing Entrance-2018

Explanation

Jacquemier's sign, also known as Chadwick's sign, is the correct term for the dusky or bluish-purple discoloration of the vestibule and anterior vaginal wall.
This color change is a probable sign of pregnancy, typically appearing around the 8th week.
The underlying cause is increased blood flow and venous congestion in the pelvic tissues, a physiological response to hormonal changes in early pregnancy.

Option B: 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 the hypertrophy of the uterine artery.
Option C: Palmer's sign is also a tactile sign. It describes the regular, rhythmic uterine contractions that can be elicited during a bimanual examination in early pregnancy.
Option D: Hegar's sign is another tactile sign. It is characterized by the softening and compressibility of the lower uterine segment (the isthmus), which is felt between the fingers during a bimanual exam.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Probable signs of pregnancy as background academic context rather than a clinical decision trigger.
Recognizing probable signs like Jacquemier's sign is a key nursing skill in early pregnancy assessment. It helps in forming a presumptive diagnosis and guides further confirmatory testing.
It is crucial to differentiate these signs to avoid misinterpretation. While Jacquemier's sign is a color change, Osiander's, Palmer's, and Hegar's signs are all detected by touch during a physical examination.
Patient education is vital. A nurse should explain that while these signs are strong indicators, they are not conclusive proof of pregnancy. Confirmation requires positive signs like a fetal heartbeat on Doppler or visualization on ultrasound.
