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: A severe headache is a common adverse effect of epidural anesthesia, especially if there is a dural puncture (also known as a postdural puncture/spinal headache). This can occur when cerebrospinal fluid leaks from the punctured dura, leading to a decrease in intracranial pressure and causing a headache that typically worsens when the client is upright. B. Tachycardia: Tachycardia is not typically associated with epidural anesthesia. In fact, epidural anesthesia can sometimes lead to bradycardia (slow heart rate) due to the sympathetic blockade caused by the anesthesia. C. Rapid rise in temperature: A rapid rise in temperature is not a typical response to epidural anesthesia. It may indicate an infection or other complication, but it is not a common side effect of the procedure itself. D. Hypertension: Epidural anesthesia generally causes vasodilation and can lead to hypotension (low blood pressure), rather than hypertension. Monitoring for hypotension is a more common concern following epidural anesthesia.
