Correct Answer: B

Rationale: Culdocentesis is the correct procedure performed to assess the pelvic cavity, often used in the diagnosis of Pelvic Inflammatory Disease. Paracentesis involves the aspiration of fluid from the abdominal cavity, not typically done for PID. Hysterectomy is the surgical removal of the uterus and is not a diagnostic investigation for PID. Douching is a hygiene practice and not a diagnostic procedure for PID.

Correct Answer: A

Rationale: After a tubectomy procedure, the Fallopian tube remains blocked. This is the correct answer because tubectomy involves the surgical blocking or sealing of the Fallopian tubes to prevent eggs from reaching the uterus, thus preventing pregnancy. Choice B, the cervix, is incorrect as it is not blocked during a tubectomy. Choice C, the uterine cavity, is also incorrect as the procedure does not involve blocking this part of the reproductive system. Choice D, none, is incorrect as the purpose of tubectomy is to block the Fallopian tubes.

Correct Answer: C

Rationale: Abortion is important due to the serious complications it can cause, such as infections and maternal death. Choices A and B are incorrect because ease of conducting or diagnosing abortion procedures does not inherently make abortion important. Choice D is incorrect because not all the options listed are reasons why abortion is important; only choice C highlights the critical aspect of potential complications.

Correct Answer: A

Rationale: The correct answer is A: Urine or whole blood. The Gravindex test is designed to detect Human Chorionic Gonadotrophic hormone (HCG) in urine or whole blood samples. HCG is a hormone produced during pregnancy, and its presence in urine or blood can indicate pregnancy. Choices B, C, and D are incorrect as the Gravindex test is not intended to detect HCG in amniotic fluid, saliva, or cervical mucus. These bodily fluids are not typically used for pregnancy testing purposes.

Correct Answer: A

Rationale: A cord inserted to the very edge of the placenta is known as battledore insertion. This occurs when the cord is attached to the fetal membranes at the placental margin rather than directly to the placental tissue. Placenta velamentosa refers to the condition where the umbilical cord inserts into the fetal membranes before it reaches the placenta. Placenta accreta is a condition where the placenta attaches too deeply into the uterine wall. Vasa Praevia is a condition where fetal blood vessels run across or near the internal cervical opening.
