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. At 34-40 weeks of pregnancy, the breast changes include:

• A. Nipples become prominent and mobile.
• B. Colostrum can be expressed.
• C. Breasts become tender.
• D. Montgomery's tubercles are prominent.

Correct answer: D

Rationale: During the 34-40 weeks of pregnancy, Montgomery's tubercles become prominent. These are sebaceous glands on the areola, not the nipples. Choice A is incorrect as it describes the changes in nipples, not Montgomery's tubercles. Choice B is incorrect as colostrum production usually starts around the 16th week. Choice C is incorrect as breast tenderness is more common in early pregnancy due to hormonal changes.

3. What causes the changes in appearance seen in boys at the time of puberty?

• A. Prolactin
• B. Adrenaline
• C. Estrogen
• D. Testosterone

Correct answer: D

Rationale: During puberty, boys experience physical changes such as growth of facial and body hair, deepening of the voice, and muscle development. These changes are primarily driven by the hormone testosterone. Testosterone is responsible for the development of male secondary sexual characteristics. Therefore, the correct answer is testosterone. Choices A, B, and C are incorrect because prolactin, adrenaline, and estrogen do not play a significant role in the development of male secondary sexual characteristics during puberty.

4. In Primary Health care, the concept of accessibility requires that:

• A. Patients should be required to accept one service in order to gain access to another type of service.
• B. A referral network, including transportation, to higher-level facilities should be coupled to PHC services.
• C. Patients' access to services should be contingent on social or cultural backgrounds, age, and marital status.
• D. Patients' access to services should be based on one's educational status.

Correct answer: B

Rationale: In Primary Health care, accessibility entails having a referral network and transportation system in place to link patients to higher-level facilities when needed. Choice A is incorrect because patients should not be required to accept one service to access another. Choice C is incorrect as access to services should not be contingent on social or cultural backgrounds, age, or marital status. Choice D is also incorrect because educational status should not determine patients' access to healthcare services.

5. Inevitable abortion occurs when:

• A. The ovum dies in utero and the decidua capsularis remains intact.
• B. The cervix is open, and the products of conception are about to be expelled.
• C. The products of conception are expelled before the 20th week of gestation.
• D. The fetus dies and is expelled in the first trimester.

Correct answer: B

Rationale: Inevitable abortion occurs when the cervix is open, and the products of conception are about to be expelled. This is a critical point in the process of spontaneous abortion, indicating that expulsion of the products of conception is imminent. Choice A is incorrect as it describes a missed abortion where the ovum dies but the decidua capsularis remains intact. Choice C is incorrect as it describes an incomplete abortion where the products of conception are expelled before the completion of 20 weeks of gestation. Choice D is incorrect as it describes a missed abortion where the fetus dies and is expelled in the first trimester.
