When a client on penicillin reports hives and itching, what action should the nurse take?

When a client on penicillin reports hives and itching, it is crucial to prioritize the client's safety. The correct action is to hold the next dose of the medication and notify the healthcare provider of the symptoms. This step is essential because the presence of hives and itching may indicate an allergic reaction to penicillin. An allergic response can escalate to more severe reactions, such as anaphylaxis, which is a medical emergency.

By holding the medication, the nurse prevents further exposure to the allergen while the healthcare provider can assess the situation and decide on the best course of action. Notifying the healthcare provider ensures that the client receives appropriate care and potentially an alternative treatment plan. This approach demonstrates adherence to safe nursing practice and reinforces the importance of monitoring and responding to adverse drug reactions promptly.

While antihistamines may provide relief for itching, administering medication without addressing the allergic reaction could worsen the client's condition. Additionally, continuing with blood and urine cultures is important in many contexts, but it should not take priority over managing a suspected allergic reaction.
