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.

What should be included in the differential diagnosis of ectopic pregnancy?
- A. Inevitable abortion
- B. Dysmenorrhea
- C. Twisted ovarian cyst
- D. Fibroids
Correct Answer: C
Rationale: In the differential diagnosis of ectopic pregnancy, conditions such as twisted ovarian cysts should be considered. Twisted ovarian cysts can present with similar symptoms to ectopic pregnancy, making it important to include them in the differential diagnosis. Choices A, B, and D are not typically part of the differential diagnosis of ectopic pregnancy. Inevitable abortion refers to an imminent miscarriage, dysmenorrhea is characterized by painful menstruation, and fibroids are benign growths in the uterus, none of which are directly related to ectopic pregnancy.
Which of the following is an example of an oviparous animal?
- A. Pigeon
- B. Elephant
- C. Sheep
- D. None of the above
Correct Answer: A
Rationale: The correct answer is A: Pigeon. Oviparous animals are those that lay eggs, and pigeons fall under this category. Choice B, Elephant, is incorrect because elephants are viviparous, giving birth to live young. Choice C, Sheep, is also incorrect as sheep are viviparous animals. Choice D, None of the above, is not the correct answer as a pigeon is indeed an example of an oviparous animal.
What is the reasonable available distance from all patients to offer Primary Health Care (PHC) services?
- A. Within a 20 Km radius
- B. Within a 15 Km radius
- C. Within a 12 Km radius
- D. Within a 10 Km radius
Correct Answer: A
Rationale: The correct answer is within a 20 Km radius. Primary Health Care services should be accessible within a 20 Km radius to ensure adequate coverage for all patients. This distance allows for a reasonable reach while ensuring that individuals can access essential healthcare services in a timely manner. Choices B, C, and D are incorrect as they offer distances that may limit accessibility and coverage, potentially leaving some patients without timely access to necessary healthcare.
Which of the following hormones promotes endometrial growth?
- A. LH
- B. FSH
- C. Estrogen
- D. Progesterone
Correct Answer: C
Rationale: Estrogen is the hormone responsible for promoting endometrial growth. Estrogen helps thicken the endometrium during the menstrual cycle in preparation for implantation. LH (Choice A) and FSH (Choice B) are involved in regulating the menstrual cycle but do not directly promote endometrial growth. Progesterone (Choice D) is important for maintaining the endometrium after ovulation but is not the primary hormone responsible for promoting its growth.
The endometrial tissue of the cervix is arranged in folds known as:
- A. Racemose glands
- B. Rugae
- C. Arbor vitae
- D. Peritoneum
Correct Answer: B
Rationale: The endometrial tissue of the cervix is arranged in folds known as rugae, not Arbor vitae. Rugae are commonly found in anatomical structures like the stomach and bladder to allow expansion. Choices A, C, and D are incorrect. Racemose glands refer to branched compound glands, Arbor vitae is the tree-like appearance of the cerebellum, and Peritoneum is the serous membrane lining the abdominal cavity.
