Explanation

Visualization of the fetus by ultrasound is classified as a positive sign of pregnancy, which provides conclusive, objective proof.
Positive signs, unlike presumptive or probable signs, can only be attributed to the presence of a fetus and are not caused by other conditions.
Ultrasound can detect a gestational sac as early as 4-5 weeks and fetal cardiac activity around 6 weeks, confirming the pregnancy's presence and viability.

Option A: Amenorrhea (absence of menstruation) is a presumptive sign. It is subjective and can be caused by various other factors like stress, illness, hormonal imbalances, or significant weight changes.
Option B: Quickening (the mother's first sensation of fetal movement) is a presumptive sign. It is subjective and can be easily confused with gas or intestinal peristalsis.
Option D: Uterine enlargement is a probable sign. Although it strongly suggests pregnancy, it is not definitive as it can also be caused by conditions such as uterine fibroids, adenomyosis, or other tumors.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Classification of Signs of Pregnancy (Presumptive, Probable, and Positive) as background academic context rather than a clinical decision trigger.
Nurses must differentiate between the types of pregnancy signs to provide accurate patient education and avoid giving false assurances or causing unnecessary anxiety.
Confirming a pregnancy with a positive sign like an ultrasound is essential before initiating an antenatal care plan, which includes specific health teachings, screenings, and interventions.
What if? If a patient has amenorrhea and a positive home pregnancy test (a probable sign) but experiences severe unilateral abdominal pain, the nurse must recognize the possibility of an ectopic pregnancy, as the signs are not yet positive for a viable intrauterine pregnancy. This requires immediate medical evaluation.

How to Approach the Question

First, understand the keyword 'positive-definite'. This asks for a sign that offers 100% confirmation of pregnancy.
Recall the three classifications of pregnancy signs: Presumptive (subjective, could have other causes), Probable (objective but not 100% conclusive), and Positive (conclusive proof).
Categorize each option: Amenorrhea (presumptive), Quickening (presumptive), and Uterine enlargement (probable).
Identify the only option that fits the 'Positive' category: Visualization of the fetus by ultrasound.
Select this option as it is the only definitive sign among the choices.
