A nurse is caring for a client who received epidural anesthesia during hip surgery. Which of the following manifestations should the nurse monitor as an adverse reaction?

A. Severe headache can result from epidural anesthesia due to post-dural puncture headache caused by leakage of cerebrospinal fluid. B. Rapid rise in temperature may indicate infection but is not a common reaction to epidural anesthesia. C. Hypertension is not a common adverse effect of epidural anesthesia; in fact, hypotension is more typical due to sympathetic blockade. D. Tachycardia is not a typical adverse reaction, and the most likely response to epidural anesthesia is bradycardia due to autonomic blockade.
