1.
Where does fertilization take place?
Correct Answer
B. Ampulla
Explanation
Fertilization takes place in the ampulla, which is the widest part of the fallopian tube. This is where the sperm and egg meet and fuse together, resulting in the formation of a fertilized egg or zygote. The ampulla provides the necessary environment for the sperm to swim towards the egg and for the fertilization process to occur successfully.
2.
What are some important functions of the amniotic fluid?
Correct Answer(s)
A. Protection
C. Temperature regulation
D. Lung development
Explanation
The amniotic fluid serves several important functions during pregnancy. Firstly, it acts as a protective cushion, providing a barrier against external impacts and protecting the developing fetus from injury. Secondly, it helps to regulate the temperature around the fetus, ensuring a stable and optimal environment for growth. Lastly, the amniotic fluid plays a crucial role in the development of the fetal lungs, as the fetus breathes in and out the fluid, helping the lungs to mature and practice the necessary movements for breathing after birth.
3.
What delivers oxygenated blood to the fetus?
Correct Answer
A. Vein
Explanation
Veins deliver oxygenated blood to the fetus. In the circulatory system, veins are responsible for carrying blood back to the heart. In the case of a fetus, the umbilical vein carries oxygenated blood from the placenta to the fetus. This blood is rich in nutrients and oxygen, which are essential for the growth and development of the fetus. Once the blood reaches the fetus, it is distributed to various organs and tissues through smaller blood vessels, including capillaries.
4.
The side of the placenta otherwise known as the "Dirty Duncan" is against what?
Correct Answer
D. Uterus
Explanation
The side of the placenta known as the "Dirty Duncan" is against the uterus. The placenta is an organ that develops during pregnancy and is responsible for providing oxygen and nutrients to the fetus, as well as removing waste products. It attaches to the wall of the uterus and is positioned in a way that the "Dirty Duncan" side, which is the maternal side of the placenta, is in direct contact with the uterine wall. This allows for the exchange of substances between the mother's blood and the fetus's blood.
5.
The hole in a fetus's heart that allows blood to bypass the fetal liver and lungs is called Foramen Ovale.
Correct Answer
A. True
Explanation
The explanation for the given correct answer is that the hole in a fetus's heart that allows blood to bypass the fetal liver and lungs is indeed called Foramen Ovale. This is a normal physiological feature in the fetal heart that allows oxygenated blood to flow from the right atrium directly to the left atrium, bypassing the non-functional lungs and liver. After birth, the foramen ovale usually closes, redirecting blood flow to the lungs for oxygenation.
6.
What is a subjective (presumptive) change in pregnancy?
Correct Answer
B. Amenorrhea
Explanation
Amenorrhea refers to the absence of menstruation, which is a common subjective change experienced during pregnancy. This occurs because the hormonal changes in the body prevent the shedding of the uterine lining. Therefore, the absence of menstruation can be considered a presumptive sign of pregnancy.
7.
What is the average recommended weight gain for a pregnant woman?
Correct Answer
B. 25-35 lbs
Explanation
The average recommended weight gain for a pregnant woman is 25-35 lbs. This range takes into account the weight of the baby, placenta, amniotic fluid, increased blood volume, and extra fat stores needed for breastfeeding. Gaining too little weight during pregnancy can lead to complications such as low birth weight, while gaining too much weight can increase the risk of gestational diabetes and other health issues. Therefore, the recommended range of 25-35 lbs ensures a healthy pregnancy for both the mother and the baby.
8.
What is a diagnostic(positive) sign of pregnancy?
Correct Answer
D. Fetal heart beat
Explanation
Fetal heart beat is considered a diagnostic sign of pregnancy because it indicates the presence of a developing fetus. This can be detected through various methods such as ultrasound or a Doppler device. The presence of a fetal heart beat confirms the pregnancy and is an important milestone in prenatal care. Hegar's sign, nausea/vomiting, and urinary frequency are also common signs of pregnancy, but they are not considered diagnostic signs as they can be present in other conditions as well.
9.
What is gestation?
Correct Answer
B. Number of weeks since first day of last menstrual period
Explanation
Gestation refers to the period of time during which a fetus develops inside the womb of a pregnant woman. It is typically measured in weeks and is calculated from the first day of the woman's last menstrual period. This is because it is difficult to determine the exact date of fertilization, but the date of the last menstrual period is usually known and can be used as a starting point for estimating gestation.
10.
How EARLY can you hear the fetal heart rate?
Correct Answer
B. 12 weeks
Explanation
The fetal heart rate can be heard as early as 12 weeks. This is because by this time, the baby's heart has developed and is functioning well enough to be detected using a Doppler device. Before 12 weeks, the fetal heart is still in the early stages of development and may not be strong enough to produce a detectable sound.
11.
Following Nagele’s rule, how do you figure out estimated date of delivery?
Correct Answer
D. Begin with first day of the last menstrual period, subtract 3 months and add 7 days
Explanation
According to Nagele's rule, the estimated date of delivery is calculated by beginning with the first day of the last menstrual period, subtracting 3 months, and then adding 7 days. This method is used to estimate the due date of a pregnancy based on the woman's menstrual cycle. By subtracting 3 months and adding 7 days to the first day of the last menstrual period, it provides an estimation of when the baby is likely to be born.
12.
When should the mother receive a Rhogam injection?
Correct Answer
A. If she is Rh negative
Explanation
The mother should receive a Rhogam injection if she is Rh negative because Rhogam is given to prevent the development of antibodies in the mother's blood that could harm future pregnancies if the baby is Rh positive.
