What term describes a spontaneous abortion with no expulsion of the products of conception and a closed cervix?

Correct Answer: C

Rationale: The correct answer is C: missed abortion. In a missed abortion, the fetus has died but has not been expelled. The cervix remains closed, and there are no signs of active miscarriage. This term specifically describes the scenario where the pregnancy is no longer viable, but the body has not recognized it yet. A: Incomplete abortion involves partial expulsion of the products of conception. B: Threatened abortion signifies a possible miscarriage with ongoing pregnancy. D: Recurrent abortion refers to multiple consecutive miscarriages.

Correct Answer: B

Rationale: The correct answer is B: Total placenta previa. In total placenta previa, the placenta completely covers the opening of the cervix, posing a risk of severe bleeding during vaginal delivery. Cesarean birth is necessary to prevent maternal hemorrhage and ensure a safe delivery. Partial abruptio placentae (A) may require cesarean birth if there is significant bleeding or fetal distress, but it's not an absolute indication for cesarean section. Ectopic pregnancy (C) and eclampsia (D) do not always necessitate cesarean birth unless there are other obstetric indications.

Correct Answer: B

Rationale: The correct answer is B: Hard boardlike abdomen. This finding indicates concealed hemorrhage in abruptio placentae because it suggests intra-abdominal bleeding causing rigidity and firmness. This is due to blood pooling in the abdomen, leading to a tense, boardlike feeling upon palpation. The other choices are incorrect because: A) Bradycardia is not a specific indicator of concealed hemorrhage in this context; C) Decrease in fundal height is more characteristic of a missed miscarriage or intrauterine fetal demise; D) Decrease in abdominal pain is not typically associated with concealed hemorrhage, which often presents with severe abdominal pain.

Correct Answer: D

Rationale: A dilation and curettage (D&C) is indicated for an incomplete abortion at 10 weeks because it involves dilating the cervix and removing remaining products of conception from the uterus to prevent infection or excessive bleeding. Incomplete abortion at 16 weeks (Choice B) would be too advanced for a D&C and may require a different procedure. A complete abortion at 8 weeks (Choice A) does not require a D&C as all products of conception have already been expelled. Threatened abortion at 6 weeks (Choice C) indicates a possible miscarriage, but a D&C is not necessary unless the miscarriage is confirmed and incomplete.

Correct Answer: A

Rationale: The correct answer is A: Decreased fibrinogen. In DIC, there is widespread activation of the coagulation cascade, leading to consumption of clotting factors like fibrinogen. This results in decreased levels of fibrinogen in the blood. Increased platelets (B) are seen in early stages, but they decrease as consumption continues. Increased hematocrit (C) is a nonspecific finding. Decreased thromboplastin time (D) is not indicative of DIC, as it would typically be prolonged due to consumption of clotting factors.
