1. What is the purpose of amniocentesis?

• A. To induce abortion
• B. To detect genetic abnormalities in the fetus
• C. To determine the baby's gender
• D. To monitor fetal growth

Correct answer: B

Rationale: Amniocentesis is a diagnostic procedure used to detect genetic abnormalities in the fetus, such as chromosomal disorders like Down syndrome. It is not performed to induce abortion. The primary purpose of amniocentesis is to assess the genetic health of the fetus, not to determine the baby's gender (Choice C). While amniocentesis can provide information about the baby's health and development, it is not primarily used for monitoring fetal growth (Choice D). Therefore, the correct answer is B.

2. Which of the following conditions is considered a multifactorial problem?

• A. Cystic fibrosis
• B. Down syndrome
• C. Diabetes mellitus
• D. XYY syndrome

Correct answer: C

Rationale: The correct answer is 'Diabetes mellitus' because it is a multifactorial disease, influenced by both genetic predisposition and environmental factors. Cystic fibrosis (choice A) is primarily a genetic disorder caused by mutations in the CFTR gene. Down syndrome (choice B) is due to an extra copy of chromosome 21. XYY syndrome (choice D) is a genetic condition where males have an extra Y chromosome. These conditions are not considered multifactorial as their origins are primarily genetic.

3. Genotypes are solely based on genetic information.

• A. TRUE
• B. FALSE
• C. Sometimes
• D. Never

Correct answer: B

Rationale: The correct answer is B - FALSE. Genotypes are solely based on genetic information and do not reflect environmental influences. Phenotypes, on the other hand, result from the interaction of genetic and environmental factors. Choices A, C, and D are incorrect because genotypes are not influenced by environmental factors, and they are determined by an individual's genetic makeup.

4. _______ is a genetic disorder in which blood does not clot properly.

• A. Cystic fibrosis
• B. Hemophilia
• C. Lymphoma
• D. Huntington’s disease

Correct answer: B

Rationale: Hemophilia is a genetic disorder characterized by a deficiency in blood clotting factors, leading to prolonged bleeding. Cystic fibrosis is a genetic disorder that affects the lungs and digestive system, not blood clotting. Lymphoma is a type of cancer originating in the lymphatic system and is not related to blood clotting abnormalities. Huntington's disease is a neurodegenerative genetic disorder that affects a person's ability to move, think, and behave.

5. Why is a client with gestational diabetes being scheduled for an amniocentesis when the fetus has an estimated weight of eight pounds (3629 grams) at 36 weeks gestation? What information is the amniocentesis seeking to obtain?

• A. Presence of a neural tube defect.
• B. Chromosomal abnormalities.
• C. Gender of the fetus.
• D. Fetal lung maturity.

Correct answer: D

Rationale: An amniocentesis in this scenario is most likely being performed to assess fetal lung maturity. This is necessary when considering early delivery due to macrosomia (large fetal size), which is a common concern in gestational diabetes. Evaluating fetal lung maturity is crucial to determine if the fetus's lungs are developed enough to support breathing independently outside the womb. The presence of a neural tube defect and chromosomal abnormalities are not typically assessed through amniocentesis in this situation, and determining the gender of the fetus is not the primary purpose of the procedure here.
