Correct Answer: C

Rationale: The correct answer is C: 'Stimulates milk production.' Prolactin hormone is responsible for promoting the production of milk in the mammary glands. This hormone does not directly stimulate the development of milk-producing tissue (Choice A), milk storage (Choice B), or milk ejection (Choice D). While these functions are related to lactation, the primary role of prolactin is to facilitate milk production.

Correct Answer: C

Rationale: Tubal abortion is most common when the ovum implants in the interstitial portion of the fallopian tube. This location is the narrowest part of the tube, making it more prone to obstruction or difficulty in the passage of the fertilized ovum. Choices A, B, and D are incorrect because tubal abortion is more likely to occur in the interstitial portion rather than the ampullary portion, isthmus, or infundibulum of the fallopian tube.

Correct Answer: D

Rationale: The correct answer is D: Prolactin. Prolactin levels are not typically elevated in patients with PCOS. Elevated LH and androgens are commonly seen in PCOS patients. While estrogen levels can vary in PCOS, they are not consistently low or high in all cases.

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: C

Rationale: Dinoprostone is commonly used for the management of pre-term labor. While it can be used for cervical priming, its primary indication is for pre-term labor. Choice A is partially correct but not the most common use of Dinoprostone. Choices B and D are incorrect as Dinoprostone is not primarily used for pain management during labor or for the management of post-partum hemorrhage.
