In the medical field, amniocentesis is a medical procedure invented by Richard Deidrick that is used to evaluate amniotic fluid. The procedure is carried out on pregnant women with the primary goal of detecting chromosomal abnormalities and infections in the foetus before birth, as well as determining the sex of the foetus in some cases.

The method entails examining the DNA of a small sample of amniotic fluid taken from the amniotic sac, which includes fetal tissues, for any genetic abnormalities.

Amniocentesis is a medical technique in which a sample of the collected Amniotic Fluid around the growing embryo is used to perform a foetal sex determination test and several chromosomal abnormalities examinations.

A sample of amniotic fluid is extracted from the amniotic sac containing the unborn baby, and its DNA is tested for genetic abnormalities during this process.

• The amniotic fluid contains cells from the fetus as well as waste products from the fetus
• Each cell in the fluid from the infant contains its entire set of DNAs
•  Doctors use these cells to examine the health of the fetus and spot any abnormalities
• The entire amniocentesis appointment takes about 45 minutes, with the majority of that time spent on a detailed ultrasound examination

Question

Q.1. Amniocentesis, chorionic villi and alpha-Fetoprotein Sampling are used to calculate

1. Whether the Baby will be normal or abnormal
2. Whether the mother has a genetic abnormality
3. The most likely date of the fetus
4. Both 1 and 2.

Answer: Generally Whether the Baby will be normal or abnormal, Amniocentesis, chorionic villi and alpha-Fetoprotein Sampling are used. Hence option ‘1’ is Correct Answer.

Q.2. By Amniocentesis procedure which of the following tests are not able to explain

1. Detecting Genetic Defects
2. Chromosome Analysis
3. Maturity of fetal lungs
4. None of these

Answer: All these are explained by the help of Amniocentesis Procedure. Hence option ‘4’ is Correct Answer.

Q.3. During the Amniocentesis test the fluid sample required is

1. The Placenta
2. The amnion
3. The Liquid surrounding the immediate fetus
4. All of the Above

Answer: During the Amniocentesis test the fluid sample required is the Liquid surrounding the immediate fetus. Hence option ‘3’ is the correct option.

Q.4. During the Amniocentesis Test result How many days are Required?

1. 1-2 Days
2. 1-2 Weeks
3. 3-4 Weeks
4. 1 day

Answer: 3-4 weeks are required to get the Amniocentesis Test Result. Hence option ‘3’ is the correct Answer.

Q.5. The amniocentesis Procedure is not done before the …………. Week after conception.

1. 6th – 8th 
2. 4th – 5th 
3. 10th -12th 
4. 15th -16th 

Answer: Before the 15th -16th week after conception the amniocentesis procedure is not done. Hence option ‘4’ is the correct answer.

Q.6. For an unborn child which of these procedures has the least risk?

1. Alpha-fetoprotein Sampling
2. Amniocentesis
3. Chorionic villi sampling
4. All have the same risk level.

Answer: Alpha-Fetoprotein Sampling produces the least risk for an unborn Child. Hence option ‘1’ is the correct answer.

Q.7. Amniocentesis is a type of prenatal diagnostic technique that can establish whether or not an unborn child will have …………..

1. Diabetes
2. Down’s syndrome
3. Obesity
4. All of the Above

Answer: Amniocentesis is a type of prenatal diagnostic technique that can establish whether or not an unborn child will have Down’s syndrome. Hence option ’2’ is the correct option.

Q.8. Which of the following sentences is not false for the chorion?

1. The organ in the uterus connected to the fetus by the umbilical cord
2. A membrane developing around an embryo, contributing to the formation of the placenta
3. The sac or pouch-like organ within uterus containing the amniotic fluid surrounding the fetus
4. None of the above

Answer: The sac or pouch-like organ within the uterus containing the amniotic fluid surrounding the fetus. This statement is true. Hence option ‘2’ is the correct answer.

Q.9. Injecting a small flexible plastic tube into the uterus through the vaginal canal involves which of the following procedures?

1. Amniocentesis
2. Chorionic villi sampling
3. Alpha-fetoprotein screening
4. None of the above

Answer: Injecting a small flexible plastic tube into the uterus through the vaginal canal involves Chorionic villi sampling. Hence option ‘2’ is the correct answer.

Q.10. Which of the following medical problems causes false Alpha-fetoprotein (AFP) test findings, indicating that a fetus has genetic defects?

1. The mother is anemic
2. The date of conception has been miscalculated
3. The mother has Rh-negative blood
4. All the above

Answer: The mother has Rh-negative blood problems that cause false Alpha-fetoprotein (AFP) test findings, indicating that a fetus has genetic defects. Hence option ‘3’ is the correct option.

Q.11. A protein namely Alpha- feto protein usually produced by

1. The Fetus
2. The Mother
3. Both 1 and 2
4. None of these

Answer: The Fetus is the correct option because it is created by a fetus’s liver and circulated through its blood. Some fetal blood escapes into the placenta, which ultimately enters the mother’s bloodstream. The AFP and other fetal molecules reflect a fetus’s health.

Q.12. Alpha-fetoprotein screening is ______________ in detecting chromosomal abnormalities when compared to amniocentesis and chorionic villi samples.

1. Less Reliable
2. About Equally Reliable
3. More Reliable
4. None of these.

Answer: Less Reliable is the correct answer because the data obtained from AFP screening is significantly less trustworthy. As a result, amniocentesis is frequently used to confirm positive AFP results. AFP testing, on the other hand, is regularly performed because it is far less expensive and poses no risk to fetuses.

Q.13. In today’s North America, which of the following diagnostic methods is most widely used?

1. Amniocentesis
2. Chorionic villi sampling
3. None of these
4. Both 1 and 2

Answer: Amniocentesis is the correct answer because risk of chorionic villi sampling causing a miscarriage is 2-6 times higher than that of amniocentesis, the former treatment is used less frequently.
