What is considered a positive sign of pregnancy?
A.
Hegar’s sign
B.
Positive pregnancy test
C.
Fetal movement felt by the examiner
D.
Uterine contractions
The Correct answer and Explanation is:
The correct answer is C. Fetal movement felt by the examiner.
Explanation
In the context of pregnancy, signs and symptoms are categorized as either presumptive, probable, or positive. Understanding these categories is crucial for nursing and obstetrical practice.
- Presumptive Signs: These are subjective signs reported by the woman but are not definitive proof of pregnancy. For example, amenorrhea (missed periods), nausea, and breast tenderness can indicate pregnancy but could also be caused by other conditions.
- Probable Signs: These signs can be observed by a healthcare provider but are not conclusive on their own. Hegar’s sign, which is the softening of the lower uterine segment, and a positive pregnancy test fall into this category. While they strongly suggest pregnancy, they do not provide definitive proof.
- Positive Signs: These signs unequivocally confirm the presence of a fetus. The most significant positive sign is C. Fetal movement felt by the examiner, which typically occurs around 20 weeks gestation but can vary. When a healthcare provider palpates fetal movements, it provides definitive evidence of fetal presence and viability.
In contrast, A. Hegar’s sign and B. Positive pregnancy test are classified as probable signs. Hegar’s sign indicates changes in the uterus, and a positive pregnancy test detects hCG (human chorionic gonadotropin) in the urine or blood, both of which can occur in cases other than pregnancy (e.g., certain tumors or hormonal disorders).
Lastly, D. Uterine contractions can occur in various situations, including false labor or other non-pregnancy-related conditions, making them unreliable as a positive sign of pregnancy.
In summary, while several indicators can suggest pregnancy, fetal movement felt by the examiner remains the most definitive and positive sign of pregnancy.
