1. What is one of the roles of the oxytocin hormone?

• A. Stimulates milk ejection.
• B. Stimulates the production of milk.
• C. Stimulates the development of lactoferrin.
• D. Stimulates the secretion of relaxin.

Correct answer: A

Rationale: The correct answer is A: 'Stimulates milk ejection.' Oxytocin is responsible for contracting the muscles around the milk ducts, pushing milk into the nipples for breastfeeding. This process is known as milk ejection or let-down. The other choices are incorrect because oxytocin's primary function is to facilitate milk ejection rather than directly stimulating the production of milk, the development of lactoferrin, or the secretion of relaxin.

2. At what point is a fetus considered viable?

• A. 26 weeks
• B. 28 weeks
• C. 37 weeks
• D. 12 weeks

Correct answer: C

Rationale: A fetus is considered viable after 37 weeks of gestation. At this stage, the fetus has a higher chance of surviving outside the womb with medical support. Choice A (26 weeks), Choice B (28 weeks), and Choice D (12 weeks) are incorrect because a fetus is not typically considered viable at those earlier gestational ages.

3. 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.

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. Laparoscopy uses a small instrument known as a laparoscope to:

• A. Take very detailed photographs
• B. Insert a hysteroscope for D&C
• C. Perform an abortion procedure
• D. Perform a hysterectomy

Correct answer: A

Rationale: Laparoscopy uses a small instrument known as a laparoscope to take very detailed photographs of the pelvic organs. This procedure is commonly used for diagnostic purposes, to visualize internal organs, and to perform minimally invasive surgeries. Choice B, inserting a hysteroscope for D&C, is incorrect as hysteroscopy is a different procedure used to examine the inside of the uterus, not the pelvic organs. Choice C, performing an abortion procedure, is incorrect as laparoscopy is not used for abortion. Choice D, performing a hysterectomy, is incorrect as although laparoscopy can be used in some cases for hysterectomy, its primary purpose is not for this procedure.
