The GIFT technique is recommended for which of the following females?

Correct Answer: D

Rationale: The correct answer is D, 'All of the above.' The GIFT technique is recommended for females who cannot produce an ovum, provide a suitable environment for fertilization, or retain the embryo inside the uterus. This technique involves transferring the unfertilized eggs and sperm directly into the fallopian tube, bypassing the need for the ovum to travel through the fallopian tube. Choices A, B, and C all represent different scenarios where the GIFT technique would be a suitable option, making option D the correct choice.

Correct Answer: B

Rationale: The correct answer is 'Inferior.' The structures of the vulva are positioned below the vagina, making them inferior. Choice A, 'Posterior,' refers to structures located at the back, not below the vagina. Choice C, 'Lateral,' means to the side, which is not the correct orientation in this context. Choice D, 'Superior,' indicates above, which is the opposite of the correct relationship described in the question.

Correct Answer: A

Rationale: The correct answer is Acrosome. The acrosome is an organelle located at the head of a sperm cell and contains enzymes that aid in the penetration of the ovum during fertilization. The Zona pellucida is a glycoprotein membrane surrounding the ovum, not an organelle. Megalis is not a relevant organelle in this context. Therefore, the correct choice is A, Acrosome.

Correct Answer: B

Rationale: Threatening abortion is characterized by a firm contracted uterus with an open os. This presentation indicates a risk of miscarriage. Choice A ('Os open') is not specific enough and does not fully describe the condition. Choices C ('Heavy bleeding') and D ('Severe cramping') can also be present in threatening abortion, but the primary characteristic is a firm contracted uterus with an open os.

Correct Answer: B

Rationale: The regenerative phase of the menstrual cycle is the phase in which the endometrium rebuilds after menstruation. This phase can vary in duration from woman to woman and cycle to cycle. Choice A, the ovulatory phase, is not variable as it typically lasts around 24 hours. Choice C, the secretory phase, is also relatively consistent in its duration. Choice D, the menstrual phase, is the shedding of the endometrial lining and usually lasts around 3-7 days.

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.

Correct Answer: A

Rationale: The correct answer is A: Linear albicantes and B: Superficial fascia. Linear albicantes are stretch marks, and the superficial fascia is one of the layers of the anterior abdominal wall. Choices C and D, Visceral peritoneum and Fascia transversalis, respectively, are not layers of the anterior abdominal wall. The visceral peritoneum is a membrane covering the abdominal organs, and the fascia transversalis is a layer deep to the transversus abdominis muscle.

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.

Correct Answer: B

Rationale: Bidder's canal is a part of the male reproductive system and receives sperm from the testes. The other choices are incorrect because Bidder's canal is not associated with receiving eggs, ammonia, or oxygenated blood.
