Nokea
Corpus luteum;
- A. is generated as a result of ovulation;
- B. secretes estrogens;
- C. secrets progesterone;
- D. secrets low amounts of testosterone
Correct Answer: C
Rationale: The corpus luteum is formed from the ruptured follicle after ovulation. It secretes progesterone, which is crucial for preparing the uterus for implantation and maintaining early pregnancy. Progesterone helps thicken the uterine lining and supports embryo development. Estrogens are mainly produced by the ovaries, not the corpus luteum. Testosterone is primarily produced by the adrenal glands and testes, not the corpus luteum. Therefore, choice C is correct as it accurately describes the main hormone secreted by the corpus luteum.

Bidder's canal receives __________.
- A. Eggs
- B. Sperms
- C. Ammonia
- D. Oxygenated blood
Correct Answer: D
Rationale: The correct answer is D: Oxygenated blood. Bidder's canal is a part of the male reproductive system and functions to transport oxygenated blood to the testicles. This is essential for maintaining the temperature required for sperm production. Eggs (A) are not transported through Bidder's canal as it is specific to male reproductive functions. Sperms (B) are produced in the testicles but are not transported through Bidder's canal. Ammonia (C) is a waste product and not involved in the circulation within the male reproductive system.
Where does fertilization usually occur in the female reproductive system?
- A. Ovary
- B. Vesicular (Graafian) follicle
- C. Uterine (fallopian) tubes
- D. Uterus
Correct Answer: C
Rationale: The correct answer is C, the uterine (fallopian) tubes. This is where fertilization usually occurs as it is the site where the egg and sperm meet. The egg is released from the ovary and travels through the fallopian tube where it can be fertilized by sperm. If fertilization occurs, the resulting embryo will then travel to the uterus for implantation. The other choices are incorrect because fertilization does not typically occur in the ovary (A) or vesicular (Graafian) follicle (B). While the uterus (D) is where the embryo implants and develops into a fetus, fertilization itself does not occur there.
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?
- A. Do you want to talk about the need for that much exercise?
- B. Exercise is healthy but can decrease body fat and cause irregular periods. Test Bank - Medical-Surgical Nursing: Concepts for Interprofessional Collaborative Care 9e 588
- C. Bingeing and purging can cause electrolyte problems in your body.
- D. Anorexic behavior can result in decreased estrogen levels.
Correct Answer: B
Rationale: The correct answer is B. Increasing exercise intensity can lead to decreased body fat percentage, impacting hormonal balance and causing irregular periods. This is known as athletic amenorrhea. Choice A is incorrect as it does not address the physiological impact of excessive exercise on menstrual cycles. Choices C and D are also incorrect as they refer to eating disorder behaviors, which are not directly related to the client's concern of irregular periods due to increased exercise.
The secretion of ovarian hormones is controlled by:
- A. the anterior pituitary;
- B. the hypothalamus;
- C. FSH;
- D. LH;
Correct Answer: B
Rationale: The correct answer is B: the hypothalamus. The hypothalamus secretes gonadotropin-releasing hormone (GnRH) which stimulates the anterior pituitary to release follicle-stimulating hormone (FSH) and luteinizing hormone (LH), which in turn regulate the secretion of ovarian hormones (estrogen and progesterone). The anterior pituitary secretes FSH and LH in response to GnRH from the hypothalamus. Therefore, the hypothalamus plays a crucial role in controlling the secretion of ovarian hormones. Choices A, C, and D are incorrect because the anterior pituitary releases FSH and LH but is not the primary controller, FSH is a hormone released by the anterior pituitary but is not the primary controller, and LH is released by the anterior pituitary but is not the primary controller of ovarian hormone secretion.
The first polar body appears in the:
- A. primary oocyte just before ovulation
- B. primary oocyte after birth
- C. secondary oocyte after fertilization
- D. primary oocyte before birth
Correct Answer: D
Rationale: The correct answer is D because the first polar body is formed during the first meiotic division of the primary oocyte before birth. The primary oocyte undergoes meiosis I to form the secondary oocyte and the first polar body. This process occurs during fetal development, not after birth.
Choice A is incorrect because the primary oocyte completes meiosis I to form the secondary oocyte and the first polar body before ovulation.
Choice B is incorrect because the primary oocyte forms the first polar body before birth, not after birth.
Choice C is incorrect because the first polar body is formed during meiosis I of the primary oocyte, not after fertilization.
