1. Which of the following is not a characteristic of an ideal contraceptive?

• A. Irreversible
• B. Easily available
• C. User-friendly
• D. Effective with least side effects

Correct answer: A

Rationale: The correct answer is A: 'Irreversible.' An ideal contraceptive should not be irreversible because it should allow individuals to have the option to discontinue its use if desired. Choices B, C, and D are characteristics of an ideal contraceptive. Contraceptives should be easily available to ensure widespread accessibility, user-friendly to promote proper and consistent use, and effective with minimal side effects to maximize safety and tolerability.

2. How do contraceptive oral pills help in birth control?

• A. Preventing ovulation
• B. Killing ova
• C. Killing sperms
• D. More than one of the above

Correct answer: A

Rationale: Contraceptive oral pills primarily work by preventing ovulation, which means Choice A is correct. Choices B and C are incorrect because oral contraceptive pills do not kill ova or sperms. Choice D is incorrect because only preventing ovulation is the primary mechanism of action for oral contraceptive pills.

3. Which of the following are layers of the anterior abdominal wall?

• A. Linear albicantes
• B. Superficial fascia
• C. Visceral peritoneum
• D. Fascia transversalis

Correct answer: A

Rationale: The correct answer is A: Linear albicantes and B: Superficial fascia. Linear albicantes are stretch marks, and the superficial fascia is one of the layers of the anterior abdominal wall. Choices C and D, Visceral peritoneum and Fascia transversalis, respectively, are not layers of the anterior abdominal wall. The visceral peritoneum is a membrane covering the abdominal organs, and the fascia transversalis is a layer deep to the transversus abdominis muscle.

4. 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.

5. Which phase of the menstrual cycle is variable?

• A. Ovulatory
• B. Regenerative
• C. Secretory
• D. Menstrual

Correct answer: B

Rationale: The regenerative phase of the menstrual cycle is the phase in which the endometrium rebuilds after menstruation. This phase can vary in duration from woman to woman and cycle to cycle. Choice A, the ovulatory phase, is not variable as it typically lasts around 24 hours. Choice C, the secretory phase, is also relatively consistent in its duration. Choice D, the menstrual phase, is the shedding of the endometrial lining and usually lasts around 3-7 days.
