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: C

Rationale: The correct answer is C: Marsupialization. Marsupialization is the surgical procedure specifically performed for Bartholin's abscess. This procedure involves creating a new duct for the Bartholin's gland to prevent future abscess formation. Choices A, B, and D are incorrect because hysterectomy involves the removal of the uterus, oophorectomy involves the removal of the ovaries, and salpingectomy involves the removal of the fallopian tubes, none of which are the appropriate procedures for treating a Bartholin's abscess.

Correct Answer: A

Rationale: Laparoscopy uses a small instrument known as a laparoscope to take very detailed photographs of the pelvic organs. This procedure is commonly used for diagnostic purposes, to visualize internal organs, and to perform minimally invasive surgeries. Choice B, inserting a hysteroscope for D&C, is incorrect as hysteroscopy is a different procedure used to examine the inside of the uterus, not the pelvic organs. Choice C, performing an abortion procedure, is incorrect as laparoscopy is not used for abortion. Choice D, performing a hysterectomy, is incorrect as although laparoscopy can be used in some cases for hysterectomy, its primary purpose is not for this procedure.

Correct Answer: B

Rationale: The correct answer is B: 80. The non-pregnant uterus typically weighs around 80 grams. This weight may vary slightly among individuals, but 80 grams is a commonly accepted average. Choices A, C, and D are incorrect as they do not reflect the typical weight of the non-pregnant uterus. It is important to remember this approximate weight for medical reference and understanding of normal anatomical variations.

Correct Answer: D

Rationale: Sterilization is considered the most effective method of contraception because it permanently prevents pregnancy. Barrier methods, hormonal pills, and IUDs are highly effective as well, but they are reversible methods and may have a higher failure rate compared to sterilization.
