Before the preovulatory surge in luteinizing hormone, granulosa cells of the follicle secrete which of the following?
- A. Testosterone
- B. Progesterone
- C. Estrogen
- D. Inhibin
Correct Answer: C
Rationale: The correct answer is C: Estrogen. Before the preovulatory surge in luteinizing hormone, granulosa cells of the follicle primarily secrete estrogen. This hormone plays a crucial role in preparing the uterine lining for implantation and regulating the menstrual cycle. Estrogen also helps in the development of secondary sexual characteristics. Testosterone (Choice A) is mainly produced by the theca cells of the follicle. Progesterone (Choice B) is primarily secreted by the corpus luteum after ovulation. Inhibin (Choice D) is secreted by granulosa cells but primarily functions to inhibit follicle-stimulating hormone (FSH) secretion from the anterior pituitary gland.

The spongy tissue of the penis fills
- A. circumcision with blood during sexual excitement
- B. spermatogenesis and causes the penis to enlarge and
- C. ejaculation become rigid during ________.
- D. erection
Correct Answer: D
Rationale: The spongy tissue of the penis fills with blood during an erection to cause the penis to become rigid. This process is essential for maintaining an erection during sexual activity. Spermatogenesis refers to the production of sperm, not the filling of spongy tissue. Circumcision does not involve the filling of spongy tissue with blood. Ejaculation is the release of semen and does not involve the filling of spongy tissue. Therefore, the correct answer is D as it accurately describes the physiological process of penile erection.
The Fallopian tube is located between:
- A. uterus;
- B. vagina;
- C. ovary;
- D. vulva;
Correct Answer: C
Rationale: The correct answer is C, ovary. The Fallopian tube is located between the ovary and the uterus. It serves as the passage for the egg to travel from the ovary to the uterus. The other choices are incorrect because the uterus (choice A) is where the fertilized egg implants and grows during pregnancy, the vagina (choice B) is the canal leading from the outside of the body to the uterus, and the vulva (choice D) is the external genitalia. Therefore, only the ovary (choice C) is the correct anatomical structure that is connected to the Fallopian tube.
Reproduction in humans usually requires
- A. the process of cloning
- B. mitotic cell division of gametes
- C. gametes with chromosomes that are not paired
- D. the external fertilization of sex cells
Correct Answer: C
Rationale: The correct answer is C because reproduction in humans typically involves the fusion of gametes with chromosomes that are not paired, resulting in the formation of a zygote with a complete set of paired chromosomes. This process is known as sexual reproduction. Choice A, cloning, does not involve the fusion of gametes and is a form of asexual reproduction. Choice B, mitotic cell division of gametes, is incorrect as gametes undergo meiosis to form haploid cells, not mitosis. Choice D, external fertilization of sex cells, is not typical in humans as fertilization usually occurs internally.
Which of the following is a reason for providing early discharge instructions and making arrangements for home care for clients undergoing mastectomy?
- A. The adverse effects of mastectomy are immediate.
- B. The wound of the surgery is highly contagious and the client should exercise isolation precautions immediately after the procedure.
- C. Most clients are not hospitalized long
- D. The suicidal tendencies in women undergoing a mastectomy are high.
Correct Answer: C
Rationale: Short hospital stays are common, necessitating early discharge planning.
Middle layer of uterus is called:
- A. Endometrium
- B. Ectometrium
- C. Myometrium
- D. Perimetrium.
Correct Answer: C
Rationale: The correct answer is C: Myometrium. The myometrium is the middle layer of the uterus composed of smooth muscle tissue responsible for uterine contractions during childbirth. The endometrium (A) is the innermost layer responsible for menstruation and implantation. Ectometrium (B) is not a correct term. Perimetrium (D) is the outermost layer of the uterus. Therefore, C is the correct choice as it accurately represents the middle layer of the uterus.
