2. Cardiac activity can be noted adjacent to the _________ __________

Cardiac activity can be noted adjacent to the yolk sac during early embryonic development. The yolk sac plays a crucial role in providing nutrients to the developing embryo before the placenta is fully formed. The yolk sac also aids in the formation of blood cells and the development of the circulatory system. Therefore, the presence of cardiac activity near the yolk sac indicates the early stages of heart development in the embryo.

3. At about 6 weeks the fetal heart rate should be about ______-______ bpm

At about 6 weeks of pregnancy, the normal fetal heart rate should range between 100 to 110 beats per minute (bpm). This range is considered within the normal range for a developing fetus at this stage of pregnancy. It is important to monitor the fetal heart rate as it can provide valuable information about the health and well-being of the baby.

4. At about 8-9 weeks the fetal heart rate should be about _______ bpm

At about 8-9 weeks of pregnancy, the fetal heart rate should be around 140 beats per minute (bpm). This is considered a normal range for the developing fetus at this stage of gestation. Monitoring the fetal heart rate is important as it can provide valuable information about the baby's well-being and development. It is typically measured using ultrasound or a handheld Doppler device.

5. Fetal pole

The embryonic period is between ____- ____ weeks.

The embryonic period refers to the stage of development during which the fetus undergoes rapid growth and organ formation. This period typically begins around the 6th week of gestation and lasts until the 12th week. During this time, the fetal pole, which is the earliest visible sign of a developing embryo, becomes apparent. Therefore, the correct answer is 6, 12.

6. Sonographic detection

Endovaginally, the embryo is usually detected by ____weeks, and it is approximately ____ mm.

By using endovaginal sonography, the embryo can typically be detected around 5.5 weeks of pregnancy. At this stage, the embryo measures approximately 2.0 mm in size. This method allows for a more detailed and accurate visualization of the embryo compared to other techniques.

7. The fetal ______ is the first organ to function with development completed by the end of the ____th week.

The fetal heart is the first organ to function in the developing fetus. By the end of the 8th week of pregnancy, the development of the heart is completed. This means that the heart is fully formed and capable of pumping blood, providing oxygen and nutrients to the growing fetus.

8. The ____________ is initially seen as a thin linear structure adjacent to the yolk sac.

The term "embryo" refers to the early stage of development of a multicellular organism, specifically after fertilization and before it becomes a fetus. In the context of the given question, the embryo is initially observed as a thin linear structure located next to the yolk sac. This suggests that the embryo is in its early stages of development and is still forming its basic structure and organs.

9. The crown rump length is measurable to _____ weeks and is considered to be the most accurate dating (+/- three days) during the first trimester. It is measured from the top of the ________ to the bottom of the ________ excluding the legs.

The crown rump length is a measurement that can be taken during the first trimester of pregnancy. It is measured from the top of the head to the bottom of the rump, excluding the legs. This measurement is considered to be the most accurate dating method during this stage, with a margin of error of +/- three days. In this case, the correct answer is that the crown rump length is measurable to 12 weeks.

10. Care must be taken not to mistake maternal _______________ pulsations as fetal cardiac activity.

Care must be taken not to mistake maternal vasculature pulsations as fetal cardiac activity. This means that when monitoring the fetal heart rate, it is important to differentiate between the mother's blood vessels pulsating and the actual heartbeat of the fetus. The maternal vasculature refers to the mother's blood vessels, which can sometimes be mistaken for the fetal heartbeat if not properly distinguished.

11. At about 14 weeks the fetal heart rate should be about _____ bpm

At about 14 weeks, the fetal heart rate should be around 150 beats per minute. This is considered a normal range for a developing fetus at this stage of pregnancy. The heart rate of the fetus is an important indicator of its overall health and development, and healthcare providers often monitor it during prenatal check-ups. A heart rate of 150 bpm suggests that the fetus is growing and developing properly, which is reassuring for expectant parents.

12. For the remainder of pregnancy after 14 weeks, the average fetal heart rate is between _________ and _________ bpm.

During the remainder of pregnancy after 14 weeks, the average fetal heart rate typically falls within the range of 120 to 180 beats per minute (bpm). This range is considered normal and healthy for a developing fetus. It is important to monitor the fetal heart rate regularly to ensure that it remains within this range, as any significant deviations could indicate potential complications or issues with the pregnancy.
