A nurse is collecting data from a client during a routine prenatal visit. The client is in their second trimester of pregnancy and reports feeling dizzy, has a racing heart, and becomes pale while lying on their back. Which of the following actions should the nurse take?

A. Incorrect. Instructing the client to take a brisk walk might exacerbate their symptoms. B. Incorrect. Checking the client's temperature is not indicated based on the reported symptoms. C. Incorrect. Providing orange juice might help with low blood sugar but doesn't directly address the reported symptoms. D. Correct. Positioning the client on their left side can improve blood flow to the heart and uterus, alleviating symptoms of dizziness and racing heart that can occur due to pressure on the vena cava when lying flat on the back.
