A nurse is caring for a client who is pregnant and is experiencing premature contractions. The client has a new prescription for nifedipine 10 mg three times per day. Which of the following actions should the nurse take?

A. Discontinue the medication after three doses.: The nurse should not independently discontinue a prescribed medication without consulting the provider. Stopping nifedipine prematurely could allow premature contractions to continue, increasing the risk of preterm labor. B. Contact the provider to clarify the prescription.: Nifedipine for preterm labor is prescribed as an extended-release formulation once or twice daily. A prescription of 10 mg three times daily is unusual and may indicate a dosing error, so the nurse should clarify with the provider before administration. C. Administer the medication sublingually.: Nifedipine for preterm labor is usually given orally in immediate- or extended-release form, not sublingually, unless specifically instructed for hypertensive emergencies. Sublingual administration could lead to rapid absorption and hypotension. D. Give the medication before meals.: Timing relative to meals is not the primary concern for nifedipine in preterm labor. While food may slightly delay absorption, the critical issue is verifying safe and appropriate dosing for the pregnant client.
