Final answer:
The nurse should assess for abruptio placentae in a pregnant client in labor who admits to recent cocaine use, due to the vasoconstrictive effects of the drug.
Step-by-step explanation:
When a pregnant client in labor admits to recent cocaine use, the nurse should assess for a variety of potential complications, one of which is abruptio placentae. Cocaine use during pregnancy is associated with many adverse outcomes, including placental abruption. Cocaine can cause vasoconstriction and reduced uteroplacental blood flow, leading to the placenta detaching from the uterine wall prematurely. This condition can cause severe pain, bleeding, and pose significant risks to both the mother and the fetus.
