A nurse is reinforcing teaching about fetal development with a group of women who are pregnant. Which of the following statements should the nurse include in the teaching?
You will start to feel the baby move at 24 weeks
Sex of the baby is determined by week 8
The baby’s heartbeat is audible by a Doppler stethoscope at 12 weeks
Very fine hairs called lanugo cover your baby’s entire body by 36 weeks
The Correct Answer is C
Choice A:
It is incorrect to state that all women will start to feel the baby move at 24 weeks. While this is a common timeframe, the exact timing of when a woman first feels fetal movements, known as quickening, can vary. Some women may feel movement as early as 16 weeks, while others may not feel it until closer to 25 weeks. Factors such as the position of the placenta, the woman's body size, and whether it is her first pregnancy can influence when she first perceives movement.
Choice B:
While the baby's sex is genetically determined at conception, it is not typically visible on ultrasound until around 18-20 weeks of gestation. This is due to the development of the external genitalia, which occurs between 11 and 14 weeks. It is not accurate to state that the sex is always definitively determined by week 8.
Choice D:
Lanugo, the fine hair that covers a fetus's body, is typically present between 14 and 20 weeks of gestation. It starts to disappear around 32-36 weeks, and most babies are born without it. Therefore, it is incorrect to say that lanugo covers the entire body at 36 weeks.
Choice C:
The fetal heartbeat can be detected by a Doppler stethoscope as early as 10-12 weeks of gestation. This is often a reassuring milestone for pregnant women, as it provides audible confirmation of the baby's presence and well-being. It is a common practice for healthcare providers to use a Doppler stethoscope during prenatal visits to assess the fetal heart rate and monitor fetal development.

Correct Answer is C
Explanation
Choice A: Scrambled eggs
While eggs contain protein and iron, they do not significantly enhance iron absorption.
Consuming eggs alongside ferrous sulfate has not been shown to significantly improve iron uptake. Therefore, scrambled eggs are not the most effective choice to promote iron absorption from ferrous sulfate.
Choice B: A high fiber meal
High-fiber foods can interfere with iron absorption.
Fiber binds to iron, making it less available for absorption in the small intestine. Consuming ferrous sulfate with a high-fiber meal can potentially reduce its effectiveness.
Choice C: Orange juice
Orange juice is a rich source of vitamin C, which significantly enhances iron absorption.
Vitamin C converts non-heme iron (the form of iron in ferrous sulfate) into a more easily absorbed form.
Studies have shown that consuming vitamin C with iron supplements can increase iron absorption by up to 300%.
This makes orange juice the optimal choice to accompany ferrous sulfate, ensuring optimal absorption and effectiveness in treating iron deficiency anemia.
Correct Answer is A
Explanation
Choice A:
Fetal heart tone location: In a frank breech presentation, the fetal buttocks are positioned downward and the legs are extended straight up toward the head, placing the fetal heart closer to the mother's upper abdomen. This results in fetal heart tones being heard above the umbilicus at midline.
Gestation period: At 9 weeks of gestation, the fetus is still small and has ample room to move within the uterus, making breech presentations more common. However, it's important to note that the ideal position for childbirth is cephalic, with the head down.
Other presentations:
Cephalic presentations typically have fetal heart tones below the umbilicus.
Transverse presentations usually have fetal heart tones laterally, off to one side of the abdomen.
Posterior presentations, while still head down, can have fetal heart tones that are difficult to locate or muffled due to the position of the fetal back against the mother's spine.
Choice B:
Fetal position: In a transverse presentation, the fetus is positioned horizontally across the uterus, with the head and buttocks on either side. This typically results in fetal heart tones being heard laterally, rather than above the umbilicus at midline.
Choice C:
Fetal position: In a cephalic presentation, the fetus is head down, with the buttocks near the fundus of the uterus. This usually results in fetal heart tones being heard below the umbilicus, rather than above it.
Choice D:
Fetal position: In a posterior presentation, the fetus is head down, but facing the mother's back. While this can sometimes make fetal heart tones difficult to locate, they are typically still heard below the umbilicus, rather than above it.
