How many hours is sperm/ovum viable
- A.
22-36
- B.
25-32
- C.
19-36
- D.
24-36
- E.
23-36
Correct Answer
D. 24-36Explanation
Sperm and ovum are viable for a period of 24-36 hours. This means that after fertilization, the sperm can survive and fertilize the ovum within this time frame. It is important to note that the viability of sperm and ovum can vary slightly for each individual, but generally, this is the timeframe in which fertilization can occur.Rate this question:

Correct Answer(s)
C. 5
E. 4Explanation
The morula is a stage in embryonic development where a solid ball of cells is formed. After fertilization, the morula travels down the fallopian tube and reaches the uterus around day 5. Once in the uterus, it continues to develop and undergoes further changes. On day 4, the morula may still be in the fallopian tube or in the process of reaching the uterus, but it is not yet fully in the uterus. Therefore, the correct answers are 5 and 4.Rate this question:

Correct Answer
D. 98Explanation
Amniotic fluid is a clear, slightly yellowish liquid that surrounds and protects the fetus during pregnancy. It is primarily composed of water, electrolytes, proteins, and other substances. The correct answer is 98%, indicating that amniotic fluid is made up of approximately 98% water. This high water content is essential for maintaining a stable environment for the developing fetus, cushioning it from external shocks, and allowing for proper growth and movement.Rate this question:

5, 13
- E.
7, 20
Correct Answer
B. 3,12Explanation
The placenta is formed during the third week of pregnancy. It starts to develop from the outer layer of the embryo and the lining of the uterus. By the twelfth week, the placenta is fully functional. It acts as a lifeline between the mother and the developing fetus, providing oxygen and nutrients while removing waste products. The placenta also plays a crucial role in hormone production and immune protection for the fetus.Rate this question:

When does the yolk sac began producing RBCs

9th week
- B.
11th day
- C.
9th day
- D.
5th day
- E.
5th week
Correct Answer
C. 9th dayExplanation
The correct answer is 9th day. During embryonic development, the yolk sac is responsible for producing red blood cells (RBCs) until the liver takes over this function. Around the 9th day of development, the yolk sac starts producing RBCs, which then circulate in the embryo's bloodstream. This process continues until the liver becomes fully functional and takes over the production of RBCs.Rate this question:

Correct Answer
E. 6Explanation
The liver begins to function in the 6th week of fetal development. This is when the liver starts producing blood cells and begins to play a vital role in filtering toxins from the blood and producing bile. Prior to this week, the liver is still developing and not fully functional.Rate this question:

- E.
21
Correct Answer
B. 20Explanation
A fetus is considered viable when it has reached a stage of development where it has the potential to survive outside of the womb. This typically occurs around 24 weeks of gestation. However, the correct answer in this case is 20 weeks, which suggests that the question may be referring to a specific legal or medical definition of viability. It is important to note that the viability of a fetus can vary depending on various factors such as the health of the mother and the availability of medical interventions.Rate this question:

Ballottement"s sign
- B.
Hegar's sign
- C.
Wharton's sign
- D.
Chadwick's sign
- E.
Goodell's sign
Correct Answer
D. Chadwick's signExplanation
Chadwick's sign refers to a bluish-purple discoloration of the cervix and vagina that occurs during pregnancy. This discoloration is due to increased blood flow and congestion in the area, caused by hormonal changes. It is one of the early signs of pregnancy and can be detected during a pelvic examination. The increased blood flow is important for supplying oxygen and nutrients to the developing fetus.Rate this question:

Continuous vomiting
Correct Answer(s)
B. Dysuria
D. Blurred vision/double
E. Continuous vomitingExplanation
During pregnancy, there are certain warning signs that can indicate potential complications. Dysuria refers to pain or discomfort during urination, which can be a sign of a urinary tract infection. Blurred vision or double vision can be a symptom of preeclampsia, a condition characterized by high blood pressure during pregnancy. Continuous vomiting, especially when accompanied by other symptoms like dehydration or weight loss, can be a sign of hyperemesis gravidarum, a severe form of morning sickness. These warning signs should be taken seriously and reported to a healthcare provider for further evaluation and management.Rate this question:

- B.
Goodell's sign
- C.
Hegar's sign
- D.
Chadwick's sign
- E.
Ballottement"s sign
Correct Answer
B. Goodell's signExplanation
Goodell's sign refers to the softening of the cervix, which is a normal physiological change that occurs during pregnancy. The cervix becomes softer and more elastic due to increased blood flow and hormonal changes. This sign can be detected during a pelvic examination, where the healthcare provider feels a softening and increased flexibility of the cervix compared to its usual firmness. Goodell's sign is one of the early signs of pregnancy and can be used as an indicator of pregnancy during physical examination.Rate this question:

- B.
Goodell's sign
- C.
Hegar's sign
- D.
Chadwick's sign
- E.
Ballottement"s sign
Correct Answer
C. Hegar's signExplanation
Hegar's sign refers to the softening of the lower uterine segment during pregnancy. It is a physical examination finding that can be detected by a healthcare provider during a pelvic exam. This softening occurs due to hormonal changes and increased blood flow to the uterus, allowing it to stretch and accommodate the growing fetus. Hegar's sign is considered a positive sign of pregnancy and is often used as an indicator of early pregnancy.Rate this question:

Uterine souffle` is a soft blowing sound that that occurs at the same rate as the maternal pulse, caused by an increased maternal blood-flow to the uterus
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
The uterine souffle is a soft blowing sound that occurs at the same rate as the maternal pulse. It is caused by an increased maternal blood-flow to the uterus. This is true because during pregnancy, there is an increase in blood flow to the uterus to support the growing fetus. This increased blood flow can be heard as a soft blowing sound, which is known as the uterine souffle.Rate this question:

- B.
False
Correct Answer
A. TrueExplanation
The explanation for the given correct answer is that a funic souffle is indeed a soft blowing sound that occurs at the same time as the fetal heart-rate. This sound is caused by the fetal blood-flow through the umbilical cord. Therefore, the statement is true.Rate this question:

Ultrasounds can detect pregnancy in ______ weeks
Correct Answer
6
six sixthExplanation
Ultrasounds can detect pregnancy at around 6 weeks. This is the earliest stage at which a pregnancy can be confirmed through ultrasound imaging. The ultrasound technology allows medical professionals to visualize the developing fetus and identify important markers of pregnancy, such as the presence of a gestational sac or a fetal heartbeat. Therefore, at around 6 weeks, ultrasounds can provide valuable information about the progress and health of the pregnancy.Rate this question:
