Which of the following is a contraceptive?

Correct Answer: D

Rationale: The correct answer is D, All of these. Copper T, Condom, and Diaphragm are all examples of contraceptives used to prevent pregnancy. Copper T is an intrauterine device (IUD) that is placed inside the uterus to prevent pregnancy. Condoms are barrier contraceptives worn over the penis or inserted into the vagina to prevent sperm from reaching the egg. Diaphragms are also barrier contraceptives that cover the cervix to prevent sperm from entering the uterus. Therefore, all options listed (Copper T, Condom, Diaphragm) are indeed contraceptives, making 'All of these' the correct choice.

Correct Answer: B

Rationale: Inevitable abortion is characterized by an open os. This condition is associated with heavy bleeding. While severe cramping can be present in inevitable abortion, the key characteristic is the open os, making choice B the correct answer. Choices A and D are incorrect because they do not specifically describe the defining feature of inevitable abortion, which is the open os.

Correct Answer: A

Rationale: A broad ligament hematoma occurs when there is a rupture in the mesenteric border of the tube. This typically happens due to trauma or other underlying conditions. Choices B, C, and D are incorrect because a broad ligament hematoma specifically involves a rupture in the mesenteric border of the tube, not the ovarian ligament, broad ligament, or uterine wall.

Correct Answer: D

Rationale: Human chorionic gonadotropin (hCG) is the hormone detected in pregnancy tests. During pregnancy, the placenta produces hCG, which can be detected in the urine or blood to confirm pregnancy. Estrogen and progesterone are also essential hormones in pregnancy but are not typically used for pregnancy tests. Luteinizing hormone (LH) is involved in the menstrual cycle and ovulation, not pregnancy.

Correct Answer: A

Rationale: The correct answer is A: Ciliated epithelium. The fallopian tubes are lined with ciliated epithelium, which helps to move the egg from the ovary to the uterus. Choice B, Stratified epithelium, is incorrect because the fallopian tubes are lined with a single layer of cells. Choice C, Columnar epithelium, is incorrect as it does not accurately describe the lining of the fallopian tubes. Choice D, Endometrium, is incorrect because the endometrium is the inner lining of the uterus, not the fallopian tubes.

Correct Answer: C

Rationale: There are two arteries in an umbilical cord. The umbilical cord contains two arteries and one vein. Artery carries blood away from the fetus, while the vein returns blood to the fetus. Therefore, choices A, B, and D are incorrect as they do not represent the correct number of arteries in an umbilical cord.

Correct Answer: A

Rationale: The correct answer is A, Copper-T. Copper-T is an intrauterine device that releases copper ions, which suppress sperm motility and inhibit the implantation of the blastocyst. This method mainly works by preventing fertilization and, if fertilization occurs, by making the endometrium less receptive to implantation. Choices B, C, and D are incorrect. The diaphragm is a barrier method that prevents sperm from reaching the cervix; contraceptive pills mainly work by suppressing ovulation and altering cervical mucus to prevent sperm from reaching the egg; condoms are barrier methods that prevent sperm from entering the vagina.

Correct Answer: B

Rationale: The correct answer is B because the Platypelloid pelvis indeed has an oval inlet. Gynaecoid pelvis, not mentioned in the choices, has a round inlet. Anthropoid pelvis has a long, narrow oval inlet, which makes choice C incorrect. Choice D is incorrect as the Android pelvis is actually heart-shaped with a narrowed inlet.

Correct Answer: C

Rationale: The correct answer is C. 'Show' is not a common symptom in all types of abortion. Lower abdominal pain, per vaginal bleeding, and backache are common symptoms associated with abortion. Lower abdominal pain may result from uterine contractions, per vaginal bleeding is a typical presentation, and backache can be a symptom due to the process of abortion. 'Show' refers to the mucus plug that blocks the cervix during pregnancy and is not a typical symptom of abortion.
