A nurse is measuring the fundal height of a client who is at 36 weeks of gestation. The client suddenly reports nausea. Which of the following actions should the nurse take?

A. Administer propranolol IV to the client: Propranolol is a beta-blocker used to treat hypertension and certain cardiac conditions. It is not indicated for sudden nausea during pregnancy and could be harmful if administered without cause. B. Position the client on her side: At 36 weeks, the gravid uterus can compress the inferior vena cava when the client lies flat, reducing venous return and causing supine hypotensive syndrome, which often presents as nausea. Turning the client to her side relieves pressure and restores circulation. C. Ask the client to increase her daily calcium intake: Calcium is important during pregnancy, especially for bone health, but increasing intake is not an acute intervention for nausea caused by positional blood flow issues. D. Use Leopold maneuvers to determine the fetal position: Leopold maneuvers assess fetal position but do not address the client’s immediate symptom of nausea, which may indicate compromised circulation from lying supine. Position change is the priority action.
