Which statement about the ovary is not true:
- A. it is a pair organ;
- B. it is a gland with mixed role;
- C. it is oval-shaped;
- D. it is located in the right flank

A: The ovary is a pair organ, as there are two ovaries in the female reproductive system. B: The ovary is a gland with mixed roles, producing hormones and releasing eggs. C: The ovary is oval-shaped, which is anatomically correct. Therefore, choice D is incorrect as the ovary is not located in the right flank.

Which patients meet the criteria for Chlamydia screening?
- A. A 40-year-old woman who is sexually active and uses barrier protection consistently
- B. A 15-year-old female woman who is sexually active with one partner
- C. A 22-year-old woman who is sexually active and uses barrier protection inconsistently
- D. A 23-year-old woman who has had four sexual partners in the last 3 months
Correct Answer: C
Rationale: The correct answer is C because the 22-year-old woman who is sexually active and uses barrier protection inconsistently is at higher risk for Chlamydia infection. Inconsistent use of barrier protection increases the likelihood of exposure to the infection. The other choices (A, B, D) do not specifically mention increased risk factors for Chlamydia. Choice A mentions consistent barrier protection, which lowers the risk. Choice B mentions having one partner, which may reduce the risk compared to multiple partners. Choice D mentions having multiple partners, which increases the risk, but it does not mention current risky behavior like inconsistent barrier protection.
The menstrual cycle is triggered each month by
- A. the release of blood from the uterus
- B. the buildup of the lining of the uterus
- C. hormones
- D. sexual intercourse
Correct Answer: C
Rationale: The correct answer is C: hormones. Hormones, specifically estrogen and progesterone, control the menstrual cycle by regulating the release of an egg from the ovary, thickening the uterine lining, and preparing the body for pregnancy or menstruation. Hormonal fluctuations throughout the cycle signal the body to shed the uterine lining if fertilization does not occur. Choices A and B are incorrect as they describe events during the menstrual cycle rather than the trigger itself. Choice D, sexual intercourse, does not directly trigger the menstrual cycle but may lead to conception, which is one of the outcomes of the menstrual cycle.

Rationale: A painless mass is often the first noticeable sign of breast cancer.
Why is rupturing of the hymen not considered a confirmation of loss of virginity?
- A. Because the hymen is not affected by any sexual activity
- B. Because the hymen can be perforated during physical activity, insertion of a tampon, or pelvic examination.
- C. Because the hymen is ruptured the first time a person urinates.
- D. Because the hymen is very delicate and may be ruptured even when running or doing strenuous exercises.
Correct Answer: B
Rationale: The hymen can be perforated by various non-sexual activities, making it an unreliable indicator of virginity.
Displacement of a bone form its joint is known as ____________________.
- A. Fracture
- B. Dislocation
- C. Displacement
- D. Sprain
Correct Answer: B
Rationale: Dislocation is the correct answer because it specifically refers to the displacement of a bone from its joint. A fracture (choice A) is a break in a bone, not a displacement. Choice C, displacement, is too general and does not specify the bone being out of a joint. A sprain (choice D) involves the stretching or tearing of ligaments, not the displacement of a bone. Therefore, dislocation is the most accurate term for the scenario described.
