Incomplete abortion is characterized by:

Correct Answer: B

Rationale: Incomplete abortion is characterized by an open os, which means that the cervix is dilated, allowing for passage of tissue. This condition typically presents with heavy bleeding as parts of the products of conception are expelled. Severe cramping may also be present due to uterine contractions. Therefore, the correct characteristic of incomplete abortion is an open os (Choice B). Choices A, C, and D are incorrect as heavy bleeding and severe cramping are symptoms associated with incomplete abortion, but they do not specifically define it, and light bleeding is not characteristic of incomplete abortion.

Correct Answer: B

Rationale: The correct answer is B: Haemorrhage. Haemorrhage is a leading cause of maternal mortality due to excessive bleeding during childbirth. While conditions like pre-eclampsia, sepsis, and obstructed labor can also be serious complications during pregnancy and childbirth, they are not the primary cause of maternal mortality worldwide.

Correct Answer: C

Rationale: During pregnancy, the layers of endometrium include decidua compacta, decidua spongiosum, and decidua basalis. Decidua functionalis is the layer that sheds during menstruation and regenerates each cycle, not a layer of the endometrium during pregnancy. Therefore, choice C is the correct answer. Decidua compacta is the layer closest to the conceptus, decidua spongiosum is the middle layer, and decidua basalis is the layer adjacent to the myometrium.

Correct Answer: A

Rationale: The correct answer is A: Fundal grip. Fundal grip is a specific Leopold maneuver used to assess the fetal lie by palpating the upper abdomen to determine the position of the baby's back and presenting part. This maneuver helps healthcare providers understand the orientation of the fetus within the uterus. Choice B, Umbilical grip, is not a recognized Leopold maneuver and does not assess fetal lie. Choice C, Pawlick grip, and choice D, Pelvic grip, are also not part of the standard Leopold maneuvers used to determine fetal lie.

Correct Answer: B

Rationale: The correct answer is B. A pelvic examination involves the inspection of the cervix and vaginal wall. This is typically done to assess the health of the reproductive organs and screen for any abnormalities. Choices A, C, and D are incorrect because while palpation and digital examination may be part of a pelvic exam, the specific focus on the cervix and vaginal wall is a key component that distinguishes it from other types of examinations.
