A client is concerned about her irregular menstrual periods since she has increased her daily workouts at the gym to 2 hours each day. What is the nurses’ best response?

Correct Answer: B

Rationale: Rationale: The correct answer is B because excessive exercise can lead to decreased body fat, which in turn disrupts hormone levels causing irregular periods. Choice A is inappropriate as it doesn't address the underlying issue. Choices C and D are incorrect as they refer to different conditions (bulimia and anorexia) not related to the client's concern.

Correct Answer: B

Rationale: The correct answer is B: seminiferous tubule. FSH (follicle-stimulating hormone) targets the seminiferous tubules in the testes to stimulate the production of sperm. FSH plays a crucial role in male reproductive function by promoting spermatogenesis. The other choices are incorrect because: A: Prostate - FSH does not directly target the prostate. C: Pituitary - FSH is secreted by the pituitary gland, it does not target the pituitary itself. D: Penis - FSH does not have a direct role in the structure or function of the penis.

Correct Answer: A

Rationale: The correct answer is A: fimbriae. Fimbriae are finger-like projections at the end of the fallopian tube that capture the released oocyte from the ovary during ovulation. The fimbriae create a gentle sweeping motion to guide the oocyte into the uterine tube for fertilization. The other choices are incorrect because the oocyte needs to be captured by the fimbriae before entering the uterine tube, infundibulum, or uterus. The fimbriae are the initial structure responsible for receiving the oocyte, making choice A the correct answer.

Correct Answer: D

Rationale: The correct answer is D: endometrium. The endometrium undergoes the most significant changes during the menstrual cycle. It thickens and sheds in response to hormonal changes for potential implantation of a fertilized egg. The vagina (A), perimetrium (B), and cervix (C) do not experience the same level of cyclic changes as the endometrium. The vagina is primarily a passageway, the perimetrium is the outer layer of the uterus, and the cervix mainly functions as an opening to the uterus. Therefore, the endometrium is the area that experiences the greatest changes in a menstrual cycle due to its role in preparing for possible pregnancy and shedding if implantation does not occur.

Correct Answer: C

Rationale: The correct answer is C: inner cell mass. After fertilization, the zygote undergoes several cell divisions to form a hollow ball of cells called a blastocyst. Within the blastocyst, the inner cell mass contains cells that will develop into the fetus. The morula is an earlier stage consisting of a solid ball of cells. The zygote is the initial cell formed from the fusion of egg and sperm, but it does not directly become the fetus. Therefore, the inner cell mass is the structure that will actually develop into the fetus, making it the correct answer.
