1. During the menstrual cycle, which hormone maintains the corpus luteum?

• A. Luteinizing hormone
• B. Follicle-stimulating hormone
• C. Progesterone
• D. Relaxin

Correct answer: A

Rationale: During the menstrual cycle, luteinizing hormone maintains the corpus luteum. The correct answer is A. Luteinizing hormone stimulates the corpus luteum to produce progesterone. Choice B, Follicle-stimulating hormone, is involved in stimulating the growth of follicles in the ovaries. Choice C, Progesterone, is produced by the corpus luteum and plays a role in preparing the endometrium for implantation. Choice D, Relaxin, is involved in processes such as softening the cervix and ligaments during pregnancy, but it is not responsible for maintaining the corpus luteum.

2. Which of the following is not a barrier method of birth control?

• A. Vaults
• B. Diaphragms
• C. Sterilization
• D. Cervical caps

Correct answer: C

Rationale: The correct answer is C, Sterilization. Sterilization is a permanent form of birth control that involves surgical procedures to prevent pregnancy by blocking the fallopian tubes or vas deferens. Barrier methods physically prevent sperm from reaching the egg, such as vaults, diaphragms, and cervical caps. These devices create a barrier to sperm, unlike sterilization. Therefore, choices A, B, and D are all considered barrier methods of birth control.

3. Oligomenorrhea is defined as a cycle longer than:

• A. 28 days
• B. 30 days
• C. 35 days
• D. 40 days

Correct answer: C

Rationale: Oligomenorrhea is defined as a menstrual cycle longer than 35 days. A cycle of 28 days (Choice A) is within the normal range, and not considered oligomenorrhea. Similarly, 30 days (Choice B) and 40 days (Choice D) are also within the normal range. The correct definition of oligomenorrhea specifically refers to cycles longer than 35 days, making Choice C the correct answer.

4. Which of the following is subsidiary uterine support?

• A. Suspensory ligament
• B. Cardinal ligament
• C. Transcervical ligament
• D. Maklouf ligament

Correct answer: B

Rationale: The correct answer is B: Cardinal ligament. The cardinal ligament is a primary uterine support structure that helps to anchor the uterus in place. The suspensory ligament also provides support for the uterus but is not considered a subsidiary uterine support. The transcervical ligament does not exist in anatomical terminology. The Maklouf ligament is a fictitious term and not recognized as a subsidiary uterine support structure.

5. 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.
