Which technique is used to detect HIV/AIDS?
- A. Northern blot and ELISA
- B. Immunoblot and ELISA
- C. Western blot and ELISA
- D. Southern blot and ELISA
Correct Answer: C
Rationale: The correct answer is C: Western blot and ELISA. Western blot and ELISA are commonly used techniques in the detection of HIV/AIDS. Western blot is used to confirm the presence of HIV antibodies in a patient's blood after an initial positive ELISA test. Northern blotting is a technique used for RNA analysis, not for detecting HIV/AIDS (Choice A). Immunoblotting is another term for Western blotting, so Choice B is incorrect. Southern blotting is used for DNA analysis, not for detecting HIV/AIDS (Choice D).

The follicular phase is to the __________ as the luteal phase is to the secretory phase.
- A. Postovulatory
- B. Menstrual
- C. Proliferative
- D. Ovulatory
Correct Answer: C
Rationale: The correct answer is C: Proliferative. The follicular phase corresponds to the proliferative phase during the menstrual cycle, characterized by the development of ovarian follicles. The luteal phase, on the other hand, corresponds to the secretory phase when the endometrium prepares for implantation. Choices A, B, and D are incorrect because they do not accurately reflect the phases being compared in the question.
What phase corresponds with the luteal phase?
- A. Menstrual phase
- B. Follicular phase
- C. Secretory phase
- D. Menstrual phase
Correct Answer: C
Rationale: The luteal phase corresponds with the secretory phase. During the menstrual cycle, the luteal phase follows ovulation and is characterized by the development of the corpus luteum, secreting progesterone to prepare the endometrium for a potential pregnancy. The other choices, menstrual phase (A), follicular phase (B), and the repeated choice of menstrual phase (D) do not align with the luteal phase and its functions.
What is a Carneous Mole defined as?
- A. Occurs when fluids drain from the blood mole, leaving a fresh firm mass.
- B. Occurs when the ovum dies and is expelled.
- C. Occurs when the fetus dies, and the membranes rupture.
- D. Occurs when the fetus survives after a failed abortion attempt.
Correct Answer: A
Rationale: A Carneous Mole is defined as when fluids drain from the blood mole, leaving a fresh firm mass. This process leads to the formation of a solid mass resembling tissue. Choice B is incorrect as it describes a different concept known as a missed abortion, where the ovum dies and is expelled. Choice C is incorrect as it describes a situation related to fetal demise and membrane rupture, not specifically the formation of a Carneous Mole. Choice D is incorrect as it refers to a scenario where the fetus survives after a failed abortion attempt, which is distinct from the definition of a Carneous Mole.
What is the function of luteinizing hormone?
- A. Maintains the corpus luteum
- B. Ripens the Graafian follicle
- C. Prepares the breasts for lactation
- D. Produces regrowth of the endometrium
Correct Answer: A
Rationale: Luteinizing hormone is responsible for maintaining the corpus luteum after ovulation. This is crucial for the production of progesterone, which helps prepare the endometrium for implantation and supports early pregnancy. Choices B, C, and D are incorrect: B is the function of follicle-stimulating hormone (FSH) which stimulates the growth of ovarian follicles, C is mainly regulated by prolactin, and D is primarily associated with estrogen and progesterone.
What is the term used to describe the gestational sac surrounded by a blood clot and retained in the tube?
- A. A carneous mole.
- B. A hydatidiform mole.
- C. A vesicular mole.
- D. A chorionic mole.
Correct Answer: A
Rationale: The correct answer is A: a carneous mole. A carneous mole occurs when a gestational sac is surrounded by a blood clot and retained in the tube. Choice B, a hydatidiform mole, is incorrect as it refers to an abnormal pregnancy characterized by the presence of hydropic chorionic villi. Choice C, a vesicular mole, is also incorrect as it is another term for a complete hydatidiform mole. Choice D, a chorionic mole, is not a recognized medical term and is therefore incorrect.
