Nursing Elites

1. Amniocentesis, a prenatal diagnostic test used to determine fetal sex, genetic anomalies, and biochemical abnormalities, is based on:

• A. The karyotyping of the amniotic fluid
• B. Chorionic villus sampling
• C. Umbilical cord blood sampling
• D. Ultrasound

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 fallopian tubes?

• A. Ciliated epithelium.
• B. Stratified epithelium.
• C. Columnar epithelium.
• D. Endometrium.

Correct answer: A

Rationale: The correct answer is A: Ciliated epithelium. The fallopian tubes are lined with ciliated epithelium, which helps to move the egg from the ovary to the uterus. Choice B, Stratified epithelium, is incorrect because the fallopian tubes are lined with a single layer of cells. Choice C, Columnar epithelium, is incorrect as it does not accurately describe the lining of the fallopian tubes. Choice D, Endometrium, is incorrect because the endometrium is the inner lining of the uterus, not the fallopian tubes.

3. Which of the following is an example of a viviparous animal?

• A. Goat
• B. Duck
• C. Crocodile
• D. None of the above

Correct answer: A

Rationale: The correct answer is A, goat. Viviparous animals give birth to live young ones instead of laying eggs. Ducks and crocodiles are oviparous, meaning they lay eggs, making them incorrect choices. 'None of the above' is incorrect because goats are a valid example of viviparous animals.

4. Appropriate Technologies and Skills:

• A. Must be selected according to universal standards
• B. Involves ensuring the woman delivers at the hospital
• C. Requires specific qualifications such as being a nurse
• D. Necessitates the presence of a doctor at the service providing facility

Correct answer: A

Rationale: The correct answer is A because appropriate technologies must adhere to universal standards to ensure their effectiveness. Choice B is incorrect because the question is not specifically referring to childbirth. Choice C is incorrect as it limits the scope to only nurses. Choice D is incorrect as it implies the necessity of a doctor, which may not always be the case.

5. Which one is not a barrier method for birth control?

• A. Diaphragms
• B. Cervical caps
• C. Vaults
• D. Intrauterine Devices (IUDs)

Correct answer: D

Rationale: The correct answer is D, Intrauterine Devices (IUDs). Barrier methods of birth control physically block sperm from reaching the egg. Diaphragms, cervical caps, and vaults are examples of barrier methods as they create a barrier that prevents sperm from reaching the cervix. In contrast, IUDs work by altering the cervical mucus and uterine lining, making it difficult for sperm to reach the egg, but they do not physically block sperm like barrier methods do.
