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 B
Explanation
Choice A rationale:
Consuming any amount of alcohol during pregnancy is not recommended. Alcohol can cross the placenta and harm the developing fetus, potentially leading to fetal alcohol spectrum disorders (FASDs). FASDs can cause a range of physical, mental, and behavioral problems, including intellectual disabilities, learning disabilities, and physical abnormalities. Even small amounts of alcohol can increase the risk of FASDs, and there is no known safe amount of alcohol to consume during pregnancy.
Choice B rationale:
Switching to whole milk during pregnancy can be a beneficial choice for several reasons:
Increased calcium and vitamin D: Whole milk is a rich source of calcium and vitamin D, which are essential for the development of the baby's bones, teeth, and muscles. Calcium also supports the mother's bone health and helps prevent pregnancy-related osteoporosis.
Healthy fats: Whole milk contains healthy fats that are important for fetal brain development and the mother's overall health. These fats also contribute to satiety and can help manage weight gain during pregnancy.
Essential nutrients: Whole milk provides a variety of other essential nutrients, including protein, vitamins A and B12, riboflavin, and zinc. These nutrients support overall health and well-being during pregnancy.
Choice C rationale:
Weight loss during pregnancy is generally not recommended unless specifically advised by a healthcare provider. Pregnancy is a time for growth and nourishment of the baby, and restricting calories or attempting to lose weight can potentially harm the developing fetus. It's important to focus on consuming a healthy, balanced diet and gaining a healthy amount of weight during pregnancy.
Choice D rationale:
Consuming high amounts of caffeine during pregnancy is not recommended. Caffeine can cross the placenta and potentially affect the baby's heart rate and sleep patterns. It's generally advised to limit caffeine intake to less than 200 milligrams per day during pregnancy.
Correct Answer is D
Explanation
Choice A: Severe nausea and vomiting
While nausea and vomiting can be common in early pregnancy, including ectopic pregnancies, they are not specific indicators of an ectopic pregnancy.
Approximately 70-80% of pregnant women experience nausea and vomiting, regardless of the location of the pregnancy. Hence, the presence of severe nausea and vomiting alone would not definitively point towards an ectopic pregnancy.
Choice B: Uterine enlargement greater than expected for gestational age
In an ectopic pregnancy, the fertilized egg implants outside the uterus, typically in the fallopian tube. This means the uterus would not be expected to enlarge as it would in a normal intrauterine pregnancy. In fact, uterine size might be smaller than expected for gestational age in cases of ectopic pregnancy.
Choice C: Copious vaginal bleeding
While vaginal bleeding can occur in ectopic pregnancies, it's not always present and is not the most common initial symptom. When bleeding does occur, it's often lighter than a normal menstrual period and may be brown or dark in color.
Copious vaginal bleeding is more likely to occur in cases of miscarriage or other pregnancy complications.
Choice D: Pelvic pain
Pelvic pain is the most common and characteristic symptom of an ectopic pregnancy.
The pain is often described as sharp, stabbing, or cramping, and it may be localized to one side of the abdomen. The pain can be intermittent or constant, and it may worsen with activity or movement.
The pain is caused by the stretching of the fallopian tube as the ectopic pregnancy grows. In some cases, the pain can be severe enough to cause nausea and vomiting.
Therefore, pelvic pain is the most reliable finding that the nurse should expect in a client with a possible ectopic pregnancy at 8 weeks of gestation.
