Which of the following is the priority intervention for a supine client whose monitor strip shows decelerations that begin after the peak of the contraction and return to the baseline after the contraction ends?
a. Increase IV infusion.
b. Elevate lower extremities.
c. Reposition to left side-lying position.
d. Administer oxygen per face mask at 4 to 6 L/min.
ANS: C
Decelerations that begin at the peak of the contractions and recover after the contractions end are caused by uteroplacental insufficiency. When the client is in the supine position, the weight of the uterus partially occludes the vena cava and descending aorta, resulting in hypotension and decreased placental perfusion. Increasing the IV infusion, elevating the lower extremities, and administering O2 will not be effective as long as the client is in a supine position.
