Final answer:
Cocaine use in early pregnancy puts a woman at risk for both Abruptio placentae and possibly Placenta previa; the nurse should be aware that cocaine's vasoconstrictive effects could lead to these complications.
Step-by-step explanation:
When taking an initial prenatal history and a woman admits to cocaine use during the early days of the pregnancy, the nurse is aware that this would put her at risk for Abruptio placentae (B) and possibly Placenta previa (A). Cocaine use during pregnancy can lead to multiple adverse effects, including placental abruption and the potential for placenta previa, though placental abruption is more commonly associated with cocaine use. The vasoconstrictive effects of cocaine can result in fetal hypoxia, leading to these conditions. The answer to the question is D: both A and B, as both conditions could potentially arise with cocaine use during pregnancy. Cocaine generally causes growth restriction, limb anomalies, central nervous system abnormalities, and an increased risk of spontaneous abortions and preterm delivery, rather than large for gestational age babies.
