Which of the following hormone stimulates the development of corpus luteum?
- A. Estrogen
- B. Progesterone
- C. Luteinizing hormone (LH)
- D. Follicle stimulating hormone (FSH)
Correct Answer: C
Rationale: The correct answer is C: Luteinizing hormone (LH). LH is responsible for stimulating the development of the corpus luteum after ovulation. It triggers the release of the egg from the follicle and promotes the transformation of the follicle into the corpus luteum, which is crucial for the production of progesterone. Estrogen (A) is involved in the development of the follicle, not the corpus luteum. Progesterone (B) is produced by the corpus luteum, not responsible for its development. FSH (D) is primarily involved in stimulating the growth of ovarian follicles, not the formation of the corpus luteum.

The process by which a secondary oocyte is ejected from the ovary is called ________.
- A. emission
- B. menses
- C. fertilization
- D. ovulation
Correct Answer: D
Rationale: The correct answer is D: ovulation. This process involves the release of a mature egg (secondary oocyte) from the ovarian follicle. During ovulation, the egg is released into the fallopian tube, where it can potentially be fertilized by sperm.
A: emission - Incorrect. This term typically refers to the discharge of semen from the male reproductive system.
B: menses - Incorrect. Menses refers to the shedding of the uterine lining during menstruation, not the release of an egg from the ovary.
C: fertilization - Incorrect. Fertilization is the process of the sperm uniting with the egg, which occurs in the fallopian tube after ovulation.
The primary oocyte completes its first meiotic division
- A. during fetal development
- B. just after ovulation
- C. just before ovulation
- D. just before fertilization
Correct Answer: D
Rationale: The correct answer is D because the primary oocyte completes its first meiotic division just before fertilization. This occurs when the oocyte is released from the ovary during ovulation. The meiotic division is completed when the sperm penetrates the oocyte, forming a zygote. Choices A, B, and C are incorrect because the primary oocyte does not complete its first meiotic division during fetal development, just after ovulation, or just before ovulation.
The process in which sperm are hormone (FSH) have on males? streamlined into a head, midpiece,
- A. Male testes are not and tail is called ________.
- B. spermatogenesis
- C. FSH functions solely in
- D. acrosomal reaction
Correct Answer: B
Rationale: The correct answer is B: spermatogenesis. Spermatogenesis is the process by which sperm cells are produced in the male testes. FSH (follicle-stimulating hormone) plays a crucial role in stimulating the production of sperm within the testes. During spermatogenesis, sperm cells go through various stages of development, including the formation of a head, midpiece, and tail. The other choices are incorrect because:
A: Male testes are not and tail is called ________. This statement is incomplete and does not make sense in the context of the question.
C: FSH functions solely in. This choice is incomplete and does not provide any relevant information about the process of sperm production.
D: Acrosomal reaction. This term refers to a specific event that occurs during fertilization and is not directly related to the overall process of sperm production in the testes.
Which of the following findings would confirm that a female client has mastitis? Choose all that apply.
- A. A crack in the nipple or the areola
- B. Multiple lumps within the breast tissue
- C. Flat and soft breasts
- D. Support the arm and the shoulder with pillows.
Correct Answer: A
Rationale: A crack in the nipple or areola is a common sign of mastitis.
The function of the epididymis is
- A. Sperm maturation
- B. Produce sperm
- C. Spermatid storage
- D. Provide nutrition to sperm
Correct Answer: A
Rationale: The correct answer is A: Sperm maturation. The epididymis is a coiled tube where sperm undergo maturation, gaining motility and ability to fertilize an egg. It does not produce sperm (incorrect B), but stores sperm for a short period (incorrect C) before ejaculation. It also does not provide nutrition to sperm (incorrect D).
