A client arrives at the emergency department with small amounts of vaginal bleeding and severe left-sided abdominal pain.
The client tells the nurse she is unsure of when her last menstrual period was, but maybe about 7 weeks ago.
The client's blood pressure is 82/55 mm/Hg, and her pulse is 120 bpm.
The nurse notifies the healthcare provider immediately due to her concern about which complication?

Choice A rationale

Abruptio placentae involves the premature separation of the placenta from the uterus, causing abdominal pain and bleeding. However, the severe left-sided pain and uncertain last menstrual period suggest another condition rather than abruption.

Choice B rationale

Gestational trophoblastic disease is characterized by abnormal growth of trophoblasts, the cells that normally develop into the placenta. It is usually identified by abnormal bleeding and unusually high hCG levels, not the acute symptoms described.

Choice C rationale

Complete abortion refers to the expulsion of all products of conception, typically accompanied by heavy bleeding and cramping. While it involves vaginal bleeding, the severe unilateral pain and low blood pressure suggest a different diagnosis.

Choice D rationale

Ectopic pregnancy, where a fertilized egg implants outside the uterus, typically causes severe unilateral pain and can lead to internal bleeding, resulting in low blood pressure and a high heart rate. These symptoms align with the client's presentation and are a medical emergency.

Choice A rationale

Monochorionic-monoamniotic twins share a single placenta and amniotic sac, increasing the risk for twin to twin transfusion syndrome (TTTS). This condition occurs due to unbalanced blood flow through the shared placenta, leading to discrepancies in blood volume between the twins.

Choice B rationale

TTTS does not result in overperfusion to both babies. Instead, it causes one twin (the donor) to become underperfused, leading to anemia and growth restriction, while the other twin (the recipient) becomes overperfused, causing polycythemia and circulatory overload, which can lead to heart failure.

Choice C rationale

TTTS is not very common in all multiple gestation pregnancies; it primarily affects monochorionic twins. In dichorionic twins, each twin has its own placenta, making TTTS highly unlikely.

Choice D rationale

Monochorionic twins sharing a placenta actually increases their risk for TTTS, not lowers it. The shared placenta creates a scenario where blood vessels can cross and lead to uneven blood flow between the twins. .
