1. Which of the following is a function of the placenta?

• A. The placenta secretes insulin.
• B. The placenta facilitates the exchange of gases and nutrients between mother and fetus.
• C. The placenta provides immunological protection to the fetus.
• D. The placenta stores fat-soluble vitamins for the fetus.

Correct answer: B

Rationale: The correct answer is B. The placenta serves as a crucial organ during pregnancy, facilitating the exchange of gases (oxygen and carbon dioxide) and nutrients (such as glucose and amino acids) between the mother and the developing fetus. This exchange is vital for the fetus's growth and development. Choices A, C, and D are incorrect. The placenta does not secrete insulin; insulin is produced by the pancreas. While the placenta provides some immune support to the fetus, its main role is not immunological protection. Additionally, storing fat-soluble vitamins is not a primary function of the placenta.

2. 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.

3. 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.

4. In missed abortion, what will the woman often experience?

• A. Severe cramping and lower abdominal pains
• B. Brownish vaginal discharge
• C. Profuse per vagina bleeding
• D. Open cervical OS

Correct answer: B

Rationale: In missed abortion, the woman often experiences brownish vaginal discharge. This is known as a symptom of missed abortion. Severe cramping and lower abdominal pains (Choice A) are more characteristic of an incomplete abortion, where not all pregnancy tissue is expelled. Profuse per vagina bleeding (Choice C) is more commonly associated with a complete abortion. Open cervical OS (Choice D) is a physical finding and not a typical symptom reported by the woman in missed abortion.

5. What type of epithelium lines the fallopian tubes?

• A. Ciliated epithelium.
• B. Stratified epithelium.
• C. Columnar epithelium.
• D. Endometrium.

Correct answer: A

Rationale: The correct answer is A: Ciliated epithelium. The fallopian tubes are lined with ciliated epithelium, which helps to move the egg from the ovary to the uterus. Choice B, Stratified epithelium, is incorrect because the fallopian tubes are lined with a single layer of cells. Choice C, Columnar epithelium, is incorrect as it does not accurately describe the lining of the fallopian tubes. Choice D, Endometrium, is incorrect because the endometrium is the inner lining of the uterus, not the fallopian tubes.
