A nurse is caring for a client who received verapamil 1 hr ago and now has a blood pressure of 80/54 mm Hg. Which of the following actions should the nurse plan to take?

A. Administer a bolus of IV fluids: Verapamil, a calcium channel blocker, can cause hypotension due to vasodilation and decreased cardiac contractility. Administering IV fluids helps increase intravascular volume and improve blood pressure, supporting perfusion to vital organs. B. Administer supplemental oxygen: While oxygen may be beneficial if hypoxia is present, the primary issue here is hypotension rather than oxygenation. Oxygen alone will not correct low blood pressure. C. Position the client's legs in a dependent position: Elevating or positioning the legs can aid venous return temporarily, but it is not sufficient to treat significant hypotension caused by verapamil. D. Administer a dose of IV diphenhydramine: Diphenhydramine is an antihistamine used for allergic reactions. There is no indication of an allergic reaction in this scenario, and it will not address verapamil-induced hypotension.
