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 could inhibit the initiating labor?
- A. Administration of an antagonist of the actions of progesterone
- B. Administration of luteinizing hormone
- C. Administration of an antagonist of prostaglandin E2 effects
- D. Mechanically dilating and stimulating the cervix
Correct Answer: C
Rationale: The correct answer is C because prostaglandin E2 plays a key role in initiating labor by promoting uterine contractions. Administering an antagonist of prostaglandin E2 effects would inhibit this process. Choice A is incorrect as progesterone levels decrease to trigger labor. Choice B is incorrect as luteinizing hormone does not directly influence labor initiation. Choice D is incorrect because mechanical dilation does not inhibit labor initiation but rather can facilitate it.
The ovarian follicles are located in the following structures, EXCEPT:
- A. the Fallopian tubes;
- B. the uterus;
- C. the medullar area of the ovary;
- D. the cortical area of the ovary;
Correct Answer: B
Rationale: The correct answer is B, the uterus. Ovarian follicles are structures within the ovaries where oocytes (eggs) develop. The Fallopian tubes, medullar area, and cortical area of the ovary all contain ovarian follicles. The uterus, on the other hand, is not where ovarian follicles are located; it is the organ where a fertilized egg implants and a pregnancy develops. Therefore, the correct answer is B because the uterus is not a structure where ovarian follicles are present.
Vaginal discharge is one of the clinical manifestations in women with
- A. Vulvovaginal candidiasis
- B. Granuloma inguinale
- C. Gonorrhea
- D. Trichomoniasis
Correct Answer: D
Rationale: Correct Answer: D - Trichomoniasis
Rationale: Trichomoniasis is a sexually transmitted infection that commonly presents with vaginal discharge. The discharge is typically frothy, yellow-green, and has a strong odor. This distinguishes it from other causes of vaginal discharge.
Summary of Other Choices:
A: Vulvovaginal candidiasis - Typically presents with thick, white, cottage cheese-like discharge.
B: Granuloma inguinale - Rare bacterial infection causing painless genital ulcers, not associated with vaginal discharge.
C: Gonorrhea - May cause vaginal discharge, but typically associated with other symptoms like pelvic pain and abnormal bleeding.
The nurse is providing teaching by telephone to a patient who is scheduled for a pelvic examination and Pap test next week. The nurse instructs the patient that she should
- A. not have sexual intercourse the day before the Pap test.
- B. shower, but not take a tub bath, before the examination.
- C. avoid douching for at least 24 hours before the examination.
- D. schedule to have the Pap test just after her menstrual period
Correct Answer: C
Rationale: The correct answer is C. Douching can alter the vaginal pH and flora, affecting the accuracy of Pap test results. By avoiding douching for at least 24 hours before the exam, the patient ensures more accurate results.
A: Not having sexual intercourse the day before the Pap test is not necessary for test accuracy.
B: Showering is recommended for hygiene but taking a tub bath does not impact the test.
D: Scheduling the test just after the menstrual period may be more comfortable for the patient, but it does not affect the accuracy of the test.
