Reproductive Health Exam Questions
Question 1 of 5
Amniocentesis, a prenatal diagnostic test used to determine fetal sex, genetic anomalies, and biochemical abnormalities, is based on:
Correct Answer: A
Rationale: The correct answer is A. Amniocentesis involves the analysis of the fetal cells present in the amniotic fluid, which is extracted from the amniotic sac surrounding the developing fetus. This fluid contains cells shed by the fetus, which can be cultured and analyzed to obtain a karyotype, providing information about the fetal sex, genetic anomalies, and biochemical abnormalities. Choices B, C, and D are incorrect because chorionic villus sampling involves obtaining a sample of the chorionic villi from the placenta, not the amniotic fluid; umbilical cord blood sampling is typically used for other purposes like assessing the baby's blood for infections or genetic disorders; and ultrasound is a diagnostic imaging technique that does not involve the analysis of fetal cells for genetic information.
Question 2 of 5
What is one of the major issues affecting adolescents in terms of sexual and reproductive health?
Correct Answer: A
Rationale: Limited access to contraceptives and family planning is indeed a major issue affecting adolescents in terms of sexual and reproductive health. This lack of access can lead to unintended pregnancies, sexually transmitted infections, and limited reproductive choices. Choice B, equal representation in decision-making, although important, is not directly related to sexual and reproductive health issues faced by adolescents. Choice C, decreased need for sexual education, is incorrect as proper sexual education is crucial in promoting healthy behaviors and preventing risks. Choice D, equal opportunities for career growth, is also unrelated to the specific issues surrounding sexual and reproductive health in adolescents.
Question 3 of 5
What is an organelle that helps the sperm to penetrate the ovum?
Correct Answer: A
Rationale: The correct answer is Acrosome. The acrosome is an organelle located at the head of a sperm cell and contains enzymes that aid in the penetration of the ovum during fertilization. The Zona pellucida is a glycoprotein membrane surrounding the ovum, not an organelle. Megalis is not a relevant organelle in this context. Therefore, the correct choice is A, Acrosome.
