Which of the following is the priority intervention for the client in a left side-lying position whose monitor strip shows a deceleration that extends beyond the end of the contraction?
a. Administer O2 at 8 to 10 L/min.
b. Decrease the IV rate to 100 mL/hr.
c. Reposition the ultrasound transducer.
d. Perform a vaginal exam to assess for cord prolapse.
ANS: A
A deceleration that returns to baseline after the end of the contraction is a late deceleration caused by placental perfusion problems. Administering oxygen will increase the client's blood oxygen saturation, making more oxygen available to the fetus. Decreasing the IV rate, repositioning the ultrasound transducer, and performing a vaginal exam to assess for cord prolapse are not effective interventions to improve fetal oxygenation.
