What defines a positive sign of pregnancy?

• A. Presence of morning sickness
• B. Internal pelvic examination findings
• C. Definitely being pregnant
• D. Fetal heart rate variability

Answer: (C)

A positive sign of pregnancy refers to definitive indicators that confirm a pregnancy. The correct choice identifies that there are signs that unequivocally establish the presence of a fetus. This includes things like ultrasound findings showing a gestational sac or fetal heart motion, which are direct evidence of pregnancy.

Other options may indicate pregnancy-related symptoms or findings but do not provide absolute confirmation. For example, morning sickness is a common symptom experienced during pregnancy but can occur in other contexts and therefore is not definitive. Internal pelvic examination findings may suggest a pregnancy but could also result from other conditions. Fetal heart rate variability, while indicative of fetal well-being during pregnancy, is also not a confirmatory sign on its own without further context or assessment.
