Question 25: Fetal UltrasoundAt approximately what gestational age can cardiac activity usually first be detected on transvaginal ultrasound?%u2022 4 weeks%u2022 6 weeks%u2022 8 weeks%u2022 10 weeks%u2022 12 weeksAnswer: 6 weeksExplanation: Cardiac activity can usually first be detected on transvaginal ultrasound at approximately 6 weeks of gestation. This corresponds to about 4 weeks after conception. However, it's important to note that this can vary, and absence of cardiac activity at 6 weeks doesn't necessarily indicate a non-viable pregnancy.
