Reproductive Health Exam

1. 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.

2. What type of epithelium lines the urinary bladder?

Correct answer: A

Rationale: The correct answer is A: Transitional epithelium. The urinary bladder is lined with transitional epithelium, a specialized type of epithelial tissue that can stretch and recoil to accommodate changes in volume as the bladder fills and empties. Stratified epithelium (choice B) is not the main lining of the urinary bladder and is found in other areas like the skin. Glandular tissue (choice C) is responsible for producing secretions and is not typically found lining the urinary bladder. Endometrium (choice D) is the inner lining of the uterus and is not present in the urinary bladder.

3. Appropriate Technologies and Skills involve:

Correct answer: A

Rationale: The correct answer is A: 'Selecting technologies according to universal standards.' Appropriate technologies and skills involve choosing tools and methods based on universal standards to ensure effectiveness and efficiency. Choice B is incorrect because the presence of a doctor is not necessarily a defining factor for appropriate technologies and skills. Choice C is incorrect as appropriate technologies are not limited to being utilized only by nurses. Choice D is incorrect as the focus should be on selecting technologies that are both easy to use and effective, not one or the other.

4. What does confidentiality in reproductive health services mean?

Correct answer: A

Rationale: Confidentiality in reproductive health services means that all information regarding the patient should be discussed only among the patient, provider, and supervisors involved in their care. Choice B is incorrect because sharing patient information with all healthcare staff goes against the principle of confidentiality. Choice C is incorrect because sharing patient information with family members should only be done with the patient's explicit consent. Choice D is incorrect as allowing patient information to be discussed in public areas violates patient privacy and confidentiality.

5. How does human sperm move?

Correct answer: A

Rationale: Human sperm moves using flagella, which are whip-like structures that aid in propulsion. Flagella are tail-like structures found in sperm cells and help them swim towards the egg for fertilization. Cilia are shorter, hair-like structures that are not involved in the movement of sperm. Neutrophils are a type of white blood cell involved in the immune response and are not related to sperm locomotion.
