Nursing Elites

1. What type of epithelium lines the vagina?

• A. Ciliated epithelium.
• B. Squamous epithelium.
• C. Columnar epithelium.
• D. Transitional epithelium.

Correct answer: B

Rationale: The correct answer is B: Squamous epithelium. The vagina is lined with non-keratinized stratified squamous epithelium. This type of epithelium provides protection against abrasion and pathogens. Choice A, Ciliated epithelium, is incorrect as ciliated epithelium is found in areas like the fallopian tubes to help move the egg towards the uterus. Choice C, Columnar epithelium, is incorrect as columnar epithelium is typically found in areas like the intestines. Choice D, Transitional epithelium, is incorrect as this type of epithelium is found in areas like the urinary bladder.

2. How does human sperm move?

• A. Flagella
• B. Cilia
• C. Neutrophils
• D. None of the above

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.

3. How many arteries are there in an umbilical cord?

• A. Three
• B. One
• C. Two
• D. Four

Correct answer: C

Rationale: There are two arteries in an umbilical cord. The umbilical cord contains two arteries and one vein. Artery carries blood away from the fetus, while the vein returns blood to the fetus. Therefore, choices A, B, and D are incorrect as they do not represent the correct number of arteries in an umbilical cord.

4. Which of the following are examples of external genitalia?

• A. Mons veneris
• B. Labia majora
• C. Vagina
• D. Cervix

Correct answer: A

Rationale: The correct answer is A: Mons veneris. The mons veneris and labia majora are considered external genitalia as they are visible externally. The vagina and cervix, on the other hand, are internal structures. The vagina is the canal leading from the external genitals to the cervix, which is the lower, narrow portion of the uterus.

5. The GIFT technique is recommended for which of the following females?

• A. Females who cannot produce an ovum
• B. Females who cannot provide a suitable environment for fertilization
• C. Females who cannot retain the embryo inside the uterus
• D. All of the above

Correct answer: D

Rationale: The correct answer is D, 'All of the above.' The GIFT technique is recommended for females who cannot produce an ovum, provide a suitable environment for fertilization, or retain the embryo inside the uterus. This technique involves transferring the unfertilized eggs and sperm directly into the fallopian tube, bypassing the need for the ovum to travel through the fallopian tube. Choices A, B, and C all represent different scenarios where the GIFT technique would be a suitable option, making option D the correct choice.
