After placing a client at 26-weeks gestation in the lithotomy position, the client complains of dizziness and becomes pale and diaphoretic. Which action should the nurse implement?

A. Place the client in the Trendelenburg position: While this position may increase venous return, it does not address the underlying cause in a pregnant client, which is usually aortocaval compression by the uterus. Simply tilting the table may be less effective than proper lateral displacement. B. Remove the client's legs from the stirrups: Removing the legs may relieve some discomfort but does not correct the maternal hypotension caused by pressure on the inferior vena cava. Additional interventions are needed to improve circulation. C. Instruct the client to take deep breaths: Deep breathing may help with anxiety or mild shortness of breath but does not resolve the hemodynamic compromise caused by supine hypotensive syndrome. D. Place a wedge under the client's hip: Placing a wedge under the right or left hip tilts the uterus off the inferior vena cava, improving venous return, cardiac output, and blood pressure. This is the priority action to relieve dizziness, pallor, and diaphoresis in a pregnant client at 26 weeks’ gestation.
