1. Which of the following is the most effective method of contraception?

• A. Barrier methods
• B. Hormonal pills
• C. Intrauterine devices (IUDs)
• D. Sterilization

Correct answer: D

Rationale: Sterilization is considered the most effective method of contraception because it permanently prevents pregnancy. Barrier methods, hormonal pills, and IUDs are highly effective as well, but they are reversible methods and may have a higher failure rate compared to sterilization.

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. Which of the following is the description of a normal cervix on speculum examination in a non-pregnant woman of reproductive age?

• A. Bright red mucosa surrounding the cervical os, in turn surrounded by smooth, pink mucosa
• B. Pink mucosa with multiple small, fluid-filled protrusions
• C. Pink, glistening, smooth mucosa of the exocervix, with a small round or fish-mouthed cervical os
• D. Smooth, pink mucosa and a small, fleshy protrusion through the cervical os

Correct answer: C

Rationale: The correct description of a normal cervix on speculum examination in a non-pregnant woman of reproductive age is pink, glistening, smooth mucosa of the exocervix, with a small round or fish-mouthed cervical os. This appearance is characteristic of a healthy cervix. Choice A is incorrect as a bright red mucosa is not normal. Choice B is incorrect as multiple small, fluid-filled protrusions suggest a different condition. Choice D is incorrect as a fleshy protrusion through the cervical os is abnormal.

4. The endometrium is shed up to the basal layer during this phase of the menstrual cycle:

• A. Ovulation
• B. Regenerative
• C. Secretory
• D. Menstruation

Correct answer: D

Rationale: The correct answer is D. During the menstrual phase of the menstrual cycle, the endometrium is shed up to the basal layer. This shedding occurs as a result of decreased levels of estrogen and progesterone, leading to the breakdown and subsequent shedding of the endometrial lining. Choice A, ovulation, is incorrect as ovulation is the release of an egg from the ovary, which occurs during the mid-cycle. Choice B, regenerative, is incorrect as it does not specifically refer to the phase where the shedding of the endometrium occurs. Choice C, secretory, is incorrect as it refers to the phase where the endometrium thickens in preparation for possible implantation of a fertilized egg, not shedding.

5. Discuss the anatomical/physiological changes in pregnancy under the following: Haematological system

• A. Blood volume and plasma volume increase, red blood cells increase, erythropoietin levels decrease, and leukocyte count increases.
• B. Blood volume and plasma volume decrease, and red blood cells decrease.
• C. No changes occur in the haematological system during pregnancy.
• D. Platelet count remains constant, and no change in coagulation factors.

Correct answer: A

Rationale: During pregnancy, the haematological system undergoes changes to support the growing fetus. Blood volume and plasma volume increase to accommodate the needs of the developing baby. Red blood cells increase to support the increased oxygen demand. Contrary to the statement, erythropoietin levels actually increase to stimulate red blood cell production. Additionally, leukocyte count increases to help the mother's immune system cope with the changes during pregnancy. Choice B is incorrect as it describes a decrease in blood components, which is not the case in pregnancy. Choice C is incorrect as there are significant changes in the haematological system during pregnancy. Choice D is incorrect as platelet count can fluctuate during pregnancy, and there are changes in coagulation factors to prevent excessive bleeding.
