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?

Rationale: A. Use Leopold maneuvers to determine the fetal position: Leopold maneuvers are not appropriate as an immediate response to sudden nausea. The priority is to relieve the symptom, which may be related to positional compression of major blood vessels. B. Position the client on her side: At 36 weeks gestation, the gravid uterus can compress the inferior vena cava when lying supine, leading to supine hypotensive syndrome. Symptoms like nausea, dizziness, and hypotension can occur. Side-lying positioning relieves the pressure and restores venous return and cardiac output. C. Administer propranolol IV to the client: Propranolol is not indicated for treating pregnancy-related nausea or hypotension. Using it without a cardiovascular diagnosis would be inappropriate and could worsen hypotensive symptoms. D. Ask the client to increase her daily calcium intake: While calcium is essential in pregnancy, especially for fetal bone development, increasing calcium intake has no immediate impact on sudden nausea or circulatory symptoms linked to maternal positioning.
