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.

- B. Ensuring that all patients sign a consent form.
- C. Ignoring patient requests for privacy.

Which hormone regulates the production of milk after childbirth?
- A. Prolactin
- B. Oxytocin
- C. Estrogen
- D. Progesterone
Correct Answer: A
Rationale: The correct answer is Prolactin. Prolactin is the hormone responsible for regulating the production of milk after childbirth. It stimulates the mammary glands in the breasts to produce milk. Oxytocin, on the other hand, is responsible for the ejection of milk from the breasts. Estrogen and progesterone play roles in the menstrual cycle and pregnancy but are not directly involved in milk production. Therefore, choices B, C, and D are incorrect.

Each breast is situated on each side of the sternum and extends between the:
- A. 1st and 6th rib
- B. 2nd and 6th rib
- C. 3rd and 6th rib
- D. 4th and 6th rib
Correct Answer: B
Rationale: The correct answer is B: 2nd and 6th rib. Each breast is situated between the 2nd and 6th ribs. This anatomical location is important for understanding breast examination techniques and identifying potential abnormalities. Choices A, C, and D are incorrect because the breasts do not extend as far as the 1st, 3rd, or 4th rib, respectively. Understanding the precise anatomical location of structures is crucial in healthcare to ensure accurate assessments and interventions.
Which of the following are layers of endometrium in pregnancy EXCEPT?
- A. Decidua compacta
- B. Decidua spongiosum
- C. Decidua functionalis
- D. Decidua basalis
Correct Answer: C
Rationale: During pregnancy, the layers of endometrium include decidua compacta, decidua spongiosum, and decidua basalis. Decidua functionalis is the layer that sheds during menstruation and regenerates each cycle, not a layer of the endometrium during pregnancy. Therefore, choice C is the correct answer. Decidua compacta is the layer closest to the conceptus, decidua spongiosum is the middle layer, and decidua basalis is the layer adjacent to the myometrium.
