1. 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.

2. Which of the following is an example of a viviparous animal?

• A. Goat
• B. Duck
• C. Crocodile
• D. None of the above

Correct answer: A

Rationale: The correct answer is A, goat. Viviparous animals give birth to live young ones instead of laying eggs. Ducks and crocodiles are oviparous, meaning they lay eggs, making them incorrect choices. 'None of the above' is incorrect because goats are a valid example of viviparous animals.

3. At what age are women likely to enter menopause?

• A. 35 - 40 years
• B. 40 - 45 years
• C. 45 - 50 years
• D. 25 - 30 years

Correct answer: C

Rationale: Women generally enter menopause between the ages of 45 - 50 years. During this stage, women experience a decline in estrogen production, leading to the cessation of menstrual cycles. Choices A, B, and D are incorrect as they do not fall within the typical age range for menopause onset. Menopause typically occurs later in life, around the age of 45 to 50 years, although individual variations exist.

4. Polymenorrhoea is defined as:

• A. Menstruation that occurs at an interval less than 35 days
• B. Menstruation that occurs at an interval greater than 35 days
• C. Menstruation that occurs at an interval less than 21 days
• D. Menstruation that occurs at an interval greater than 21 days

Correct answer: C

Rationale: Polymenorrhoea is defined as menstruation that occurs at intervals shorter than 21 days. Choice A is incorrect because it describes menstruation at intervals less than 35 days. Choice B is incorrect as it describes menstruation at intervals greater than 35 days. Choice D is incorrect as it describes menstruation at intervals greater than 21 days.

5. Which hormone is primarily responsible for the development of female secondary sexual characteristics?

• A. Progesterone
• B. Testosterone
• C. Estrogen
• D. Oxytocin

Correct answer: C

Rationale: Estrogen is primarily responsible for the development of female secondary sexual characteristics. Progesterone, while important in the menstrual cycle and pregnancy, is not primarily responsible for secondary sexual characteristics. Testosterone is the primary male sex hormone. Oxytocin is involved in labor, lactation, and social bonding, but not in the development of female secondary sexual characteristics.
