A nurse is caring for a client who has a systemic fungal infection and is receiving IV amphotericin B deoxycholate. During previous infusions, the client developed a fever and chills. Which of the following actions should the nurse take?

A. Applying a warming blanket is not appropriate, as it may exacerbate the client's reaction to the infusion and is not a standard pre-medication strategy. B. Infusing amphotericin B deoxycholate over 1 hour is too rapid; it is typically infused over 2-6 hours to minimize adverse effects. C. Administering diphenhydramine prior to the administration of amphotericin B can help prevent or alleviate infusion-related reactions such as fever and chills, which the client experienced during previous infusions. D. Monitoring vital signs once per hour following administration is insufficient; vital signs should be monitored more frequently during and immediately after the infusion to promptly detect and address any adverse reactions.
