Question 1 of 5
The main function of progesterone in the menstrual cycle is to CHAPTER 4: REPRODUCTION COMPILED BY: ZAIDI YAACOB UNAUTORIED DUPLICATION IS PROBIHITED, FOR THE CIRCULATION OF BIO095 STUDENTS ONLY
Correct Answer: C
Rationale: The correct answer is C because progesterone's main function in the menstrual cycle is to maintain the endometrium lining. Progesterone is produced by the corpus luteum after ovulation, and it helps prepare the endometrium for implantation of a fertilized egg. This hormone ensures that the endometrium is thick and ready to support a potential pregnancy. Choice A is incorrect because progesterone is not responsible for stimulating the development of the corpus luteum; instead, it is produced by the corpus luteum itself. Choice B is incorrect because progesterone does not stimulate the development of the follicle. The follicle is primarily influenced by estrogen during the follicular phase of the menstrual cycle. Choice D is incorrect because ovulation is triggered by a surge in luteinizing hormone (LH), not progesterone. LH surge causes the release of the egg from the follicle.
Question 2 of 5
The nurse is developing a teaching plan for a client who is scheduled for her first Papanicolaou test. What instruction by the nurse is the most accurate?
Correct Answer: D
Rationale: The correct answer is D. Douching can alter the cervical cells and affect the accuracy of the Pap smear results. The rationale is that douching can wash away or change the cervical cells, leading to potential misinterpretation of the test results. Choices A and B are incorrect because the timing of the test and sexual activity can indeed affect the results. Choice C is incorrect as Pap smear results need to be sent to a lab for interpretation by a healthcare provider, not done immediately in the office.
Question 3 of 5
What is the source of the male sex hormones?
Correct Answer: D
Rationale: The correct answer is D: interstitial cells. Interstitial cells, also known as Leydig cells, are located in the testes and are responsible for producing male sex hormones, primarily testosterone. The other choices, A: epididymis, B: vas deferens, and C: seminiferous tubules, are not directly involved in the production of male sex hormones. The epididymis is a structure for sperm maturation, the vas deferens is a duct for transporting sperm, and the seminiferous tubules are responsible for sperm production through spermatogenesis. Therefore, interstitial cells are the source of male sex hormones, making choice D the correct answer.
Question 4 of 5
The urethra passes through the _____ of the penis.
Correct Answer: C
Rationale: The correct answer is C: corpora spongiosum. The urethra passes through the corpora spongiosum of the penis, which is a spongy tissue that surrounds the urethra. This allows for the passage of urine and semen during ejaculation. The other choices are incorrect because: A) The tunica albuginea is a fibrous covering of the corpora cavernosa, not the urethra. B) The prepuce is the foreskin that covers the glans penis, not part of the urethra. D) The corpora cavernosa are erectile tissue responsible for penile erection, not part of the urethra's pathway.
Question 5 of 5
The mature follicle is also called a _____.
Correct Answer: A
Rationale: The correct answer is A: Graafian follicle. The mature follicle is called a Graafian follicle because it is the final stage of follicle development before ovulation. It is characterized by a fluid-filled cavity containing the oocyte. The other choices are incorrect because a granulosa cell is a type of cell found in the follicle wall, a primary follicle is an immature follicle, and a secondary follicle is an intermediate stage between the primary and Graafian follicle.
