Polymenorrhoea is defined as:

Correct Answer: C

Rationale: Polymenorrhoea is defined as menstruation that occurs at intervals shorter than 21 days. Choice A is incorrect because it describes menstruation at intervals less than 35 days. Choice B is incorrect as it describes menstruation at intervals greater than 35 days. Choice D is incorrect as it describes menstruation at intervals greater than 21 days.

Correct Answer: C

Rationale: Insomnia is a common symptom of menopause. During menopause, hormonal changes can lead to sleep disturbances, including difficulty falling asleep or staying asleep. Choice A, 'Bleeding per vagina,' is not a typical symptom of menopause but should prompt further evaluation. Choice B, 'Sleeping all the time,' is not a common symptom of menopause; in fact, insomnia, rather than excessive sleep, is more prevalent. Choice D, 'Increased concentration,' is not a symptom of menopause; cognitive changes like forgetfulness or difficulty concentrating may occur, but increased concentration is not a typical manifestation.

Correct Answer: B

Rationale: In incomplete abortions, the products of conception are retained. In a complete abortion, all the products of conception are expelled from the uterus. Threatened abortion refers to a situation where there is vaginal bleeding but the cervix remains closed, and it does not necessarily involve retention of products of conception. Mixed abortion is not a recognized medical term related to retained products of conception.

Correct Answer: D

Rationale: Pelvic Inflammatory Disease (PID) is known to affect the fallopian tubes, leading to inflammation, which is termed as salpingitis. Choice A, Oophoritis, refers to inflammation of the ovaries, not the fallopian tubes. Choice B, Endometritis, is inflammation of the endometrium, the inner lining of the uterus, not the fallopian tubes. Choice C, Salpingectomy, is a surgical procedure to remove a fallopian tube and is not a condition caused by PID.

Correct Answer: D

Rationale: Abortion is defined as the expulsion of products of conception before the 28th week of gestation. Choice A is incorrect as it describes bleeding in early pregnancy, not the definition of abortion. Choice B is incorrect as it refers to the willingness to terminate a pregnancy rather than the actual act of expulsion. Choice C is incorrect as it defines abortion as the expulsion of products of conception after the 28th week of gestation, which is considered a stillbirth.
