Which of the following is true about placenta?
- A. It produces the hormone hCG.
- B. It stimulates development of the follicle
- C. Implantation site for developing embryo.
- D. It stimulates development of corpus luteum
Correct Answer: A
Rationale: The correct answer is A: It produces the hormone hCG. The placenta is responsible for producing the hormone human chorionic gonadotropin (hCG), which is essential for maintaining pregnancy by supporting the corpus luteum to produce progesterone. This hormone is also detected in pregnancy tests.
Choice B is incorrect because the placenta does not stimulate development of the follicle; rather, it supports the corpus luteum. Choice C is incorrect as the implantation site for the developing embryo is the endometrium of the uterus, not the placenta itself. Choice D is incorrect because the placenta does not stimulate the development of the corpus luteum; instead, it supports its function through hCG production.

What is line “C” pointing to?
- A. Bladder
- B. Fimbriae
- C. Ovary
- D. Uterus
Correct Answer: C
Rationale: The correct answer is C: Ovary. Line "C" is pointing to the ovary because it is the reproductive organ responsible for producing eggs and hormones in females. The ovary is located near the fimbriae and not the bladder or uterus. The fimbriae are finger-like projections near the ovary that help guide the released egg into the fallopian tube. The bladder is an organ unrelated to reproduction, and the uterus is a separate reproductive organ responsible for housing a developing fetus. Therefore, the correct choice is the ovary as it aligns with the function and location indicated by the diagram.
The ducts or tubes responsible for receiving the ovulated oocyte and providing the site for fertilization are the ________.
- A. uterine (fallopian) tubes
- B. vagina
- C. ductus deferens
- D. uterus
Correct Answer: A
Rationale: The correct answer is A: uterine (fallopian) tubes. These tubes receive the ovulated oocyte from the ovary and provide the site for fertilization. The other choices are incorrect because:
B: The vagina is the birth canal and site for sperm deposition, not fertilization.
C: The ductus deferens is part of the male reproductive system, not involved in fertilization.
D: The uterus is where the fertilized egg implants and develops into a fetus, it is not the site for fertilization.
The _________ is a temporary organ that connects a mammalian mother to its foetus.
- A. Placenta
- B. Chorion
- C. Endometrium
- D. None of the above These are some important human reproduction MCQs for class
Correct Answer: A
Rationale: The correct answer is A: Placenta. The placenta is a temporary organ that connects a mammalian mother to its foetus by facilitating the exchange of nutrients, gases, and waste products between the mother and the developing baby. It also produces hormones necessary for pregnancy.
Explanation of other choices:
B: Chorion - The chorion is a membrane that surrounds the embryo and contributes to the formation of the placenta, but it is not the organ that directly connects the mother to the foetus.
C: Endometrium - The endometrium is the inner lining of the uterus where implantation of the fertilized egg occurs, but it is not the organ that connects the mother to the foetus.
D: None of the above - This choice is incorrect as the placenta is indeed the temporary organ that serves as the connection between the mother and the foetus in mammalian reproduction.
Mrs. Smith has been doing the arm and hand exercises you showed her until this morning when her husband told her he thought it was too dangerous. The most appropriate nursing action would be to
- A. refer Mr. Smith to the physician
- B. explain the importance of postmastectomy exercises and let him assist Mrs. Smith
- C. ask Mrs. Smith to exercise before and after her husband's visits
- D. take Mr. Smith to the physical therapy department to observe some patients with severe contractures
Correct Answer: B
Rationale: Educating the husband and allowing him to assist ensures continued compliance with necessary exercises.
In assessing a patient with suspected Chlamydia, the nurse’s actions are guided by which characteristic of this disease?
- A. Chlamydia is frequently asymptomatic and requires screening.
- B. Chlamydia is associated with a yellow-green vaginal discharge.
- C. Chlamydia is accompanied by heavy bleeding and headache.
- D. Chlamydia is only seen in immunocompromised patients.
Correct Answer: A
Rationale: The correct answer is A: Chlamydia is frequently asymptomatic and requires screening. This is because Chlamydia often does not show symptoms, making screening crucial for detection and treatment. Asymptomatic cases can lead to complications and transmission. Choices B, C, and D are incorrect. B is associated with Trichomoniasis, not Chlamydia. C describes symptoms of other conditions like pelvic inflammatory disease. D is inaccurate as Chlamydia can occur in anyone, not just immunocompromised individuals.
