A nurse is preparing to administer the initial dose of penicillin G IM to a client. The nurse should monitor for which of the following as an indication of an allergic reaction following the injection?

A. Advise the client to change positions slowly: The client's symptoms of dizziness and light- headedness upon standing suggest orthostatic hypotension, which can be managed by advising the client to change positions slowly to minimize blood pressure drops upon standing.
B. Check the client for orthostatic hypotension. Monitor the client for dysrhythmias: The client's symptoms, along with the report of waking up at night to void, are suggestive of orthostatic hypotension, a drop in blood pressure upon standing. Checking for orthostatic hypotension and monitoring for dysrhythmias are appropriate nursing actions to assess and manage this condition.

C. Advise the client to restrict potassium intake: Restricting potassium intake is not indicated based on the client's symptoms of dizziness and light-headedness. This action is not relevant to the situation described.
D. Advise the client to take the medication before bedtime: There is no indication in the scenario provided that medication timing is related to the client's symptoms. This action is not relevant to addressing the client's reported symptoms.

A. Urinary retention: While urinary retention can be a complication of epidural anesthesia, it is not the priority finding in this scenario. The priority is to address potential complications that can lead to maternal or fetal compromise.
B. Leg weakness: Leg weakness can occur as a side effect of epidural anesthesia but is not the priority finding in this scenario unless it is severe and compromises the client's ability to
mobilize or push during labor.

C. Hypotension: Hypotension is a common complication of epidural anesthesia due to sympathetic blockade, which can lead to decreased venous return and subsequent maternal
hypotension. Maternal hypotension can compromise uteroplacental perfusion, leading to fetal distress. Therefore, addressing hypotension promptly is the priority to prevent adverse maternal and fetal outcomes.
D. Temperature 39°C (102.2°F): While fever should be monitored and addressed, it is not the priority finding in this scenario unless it indicates an infection, which would require further assessment and intervention. However, maternal hypotension poses a more immediate risk to both the mother and the fetus during labor.
