Reproductive System Exam Quizlet

Correct Answer: C

Rationale: At 6-8 weeks of pregnancy, one of the changes in the breast includes the prominence of Montgomery's tubercles. These sebaceous glands around the nipple become more noticeable at this stage. Colostrum production usually occurs later in pregnancy, typically closer to the third trimester. While breast tenderness is a common symptom of early pregnancy, it is not specific to the 6-8 week timeframe. Nipples becoming more prominent and mobile may happen later in pregnancy as the body prepares for breastfeeding, but it is not a typical change seen specifically at 6-8 weeks.

Correct Answer: D

Rationale: The correct answer is D. During the menstrual phase of the menstrual cycle, the endometrium is shed up to the basal layer. This shedding occurs as a result of decreased levels of estrogen and progesterone, leading to the breakdown and subsequent shedding of the endometrial lining. Choice A, ovulation, is incorrect as ovulation is the release of an egg from the ovary, which occurs during the mid-cycle. Choice B, regenerative, is incorrect as it does not specifically refer to the phase where the shedding of the endometrium occurs. Choice C, secretory, is incorrect as it refers to the phase where the endometrium thickens in preparation for possible implantation of a fertilized egg, not shedding.

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.

Correct Answer: B

Rationale: Inevitable abortion occurs when the cervix is open, and the products of conception are about to be expelled. This is a critical point in the process of spontaneous abortion, indicating that expulsion of the products of conception is imminent. Choice A is incorrect as it describes a missed abortion where the ovum dies but the decidua capsularis remains intact. Choice C is incorrect as it describes an incomplete abortion where the products of conception are expelled before the completion of 20 weeks of gestation. Choice D is incorrect as it describes a missed abortion where the fetus dies and is expelled in the first trimester.

Correct Answer: D

Rationale: Diazepam is primarily used for relieving anxiety and muscle spasms. It is a benzodiazepine medication that works by enhancing the effects of a neurotransmitter in the brain to produce a calming effect. While Diazepam is not used for managing post-partum hemorrhage, pre-eclampsia, or inducing labor, it is essential in treating anxiety disorders, muscle spasms, and certain types of seizures. Therefore, option D is the correct answer as it aligns with the primary therapeutic use of Diazepam.
