Which of the following is a presumptive sign of pregnancy?

• A. Positive pregnancy test
• B. Hegar's sign
• C. Fatigue and nausea
• D. Fetal heartbeat detected

Answer: (C)

A presumptive sign of pregnancy is a symptom that suggests pregnancy but is not definitive. Fatigue and nausea are common early signs that many women experience when they become pregnant, and while they are indicators, they can also be related to other conditions or factors.

In comparison, a positive pregnancy test is a definitive sign of pregnancy, indicating the presence of hCG in the body. Hegar's sign is a physical sign detected during a pelvic exam, showing changes in the uterus that typically occur with pregnancy. The detection of a fetal heartbeat is a conclusive evidence of an ongoing pregnancy. Therefore, fatigue and nausea are categorized as presumptive signs, as they can occur for other reasons outside of pregnancy, making them less definitive than the other options.
