Nursing Elites

1. What does the umbilical cord contain?

• A. Pluripotent stem cells
• B. Cord blood stem cells
• C. Blood stem cells
• D. None of the above

Correct answer: B

Rationale: The correct answer is B: Cord blood stem cells. The umbilical cord contains stem cells that are found in cord blood, known as cord blood stem cells. These stem cells have the potential to develop into various types of cells and are used in medical treatments. Pluripotent stem cells are typically found in embryos and have the ability to develop into any type of cell in the body, not specifically in the umbilical cord. Choice C, blood stem cells, is a vague term that does not specifically refer to the stem cells found in the umbilical cord. Choice D is incorrect as the umbilical cord does contain cord blood stem cells.

2. What forms the vaginal lining?

• A. Squamous epithelium
• B. Stratified epithelium
• C. Vascular connective tissue
• D. Muscle coat

Correct answer: A

Rationale: The vaginal lining is primarily formed by squamous epithelium. Squamous epithelium is the correct answer because it is the type of epithelium that lines the vaginal canal. Stratified epithelium consists of multiple layers and is not the primary type found in the vaginal lining. Vascular connective tissue and muscle coat are not the main components of the vaginal lining, making them incorrect choices.

3. Which of the following is NOT a phase of the menstrual cycle?

• A. Follicular phase
• B. Ovulatory phase
• C. Luteal phase
• D. Secretory phase

Correct answer: D

Rationale: The secretory phase is not considered a distinct phase of the menstrual cycle; it is actually part of the luteal phase. During the luteal phase, the endometrium thickens due to progesterone secretion, preparing for implantation. The follicular phase is characterized by follicle development, leading to ovulation. The ovulatory phase is when the mature egg is released from the ovary. Therefore, the secretory phase is the correct answer as it is not a standalone phase but a part of the luteal phase.

4. What is the area of the uterus where the fallopian tubes are inserted known as?

• A. Fundus
• B. Corpus or body
• C. Cavity
• D. Cornua

Correct answer: D

Rationale: The correct answer is D, Cornua. The cornua refers to the upper, horn-like parts of the uterus where the fallopian tubes are inserted. The fundus (choice A) is the rounded top portion of the uterus, the corpus or body (choice B) is the main part of the uterus excluding the cervix and fundus, and the cavity (choice C) refers to the internal space within the uterus. Therefore, choices A, B, and C are incorrect as they do not specifically denote the area where the fallopian tubes are inserted.

5. Which of the following methods is used for permanent contraception in males?

• A. Vasectomy
• B. Tubal ligation
• C. Condoms
• D. Coitus interruptus

Correct answer: A

Rationale: The correct answer is A: Vasectomy. Vasectomy is a surgical procedure for permanent contraception in males by cutting or blocking the vas deferens. Choice B, Tubal ligation, is a method for permanent contraception in females by blocking or sealing the fallopian tubes. Choice C, Condoms, provide a barrier method of contraception but are not permanent. Choice D, Coitus interruptus, involves withdrawing the penis before ejaculation and is not a reliable method of contraception.
