A nurse is caring for a laboring client and notes that the fetal heart rate begins to decelerate after the contraction has started. The lowest point of deceleration occurs after the peak of the contraction. What is the priority nursing action?
Correct Answer: B
Rationale: Late decelerations are caused by uteroplacental insufficiency, indicating that the fetus is not receiving adequate oxygen during contractions. This is an emergency that requires prompt intervention. Changing the client's position helps to improve placental blood flow, which can reduce the stress on the fetus. If the decelerations continue, further interventions, including oxygen administration and notifying the provider, may be necessary.
