Final answer:
The nurse should notify the food services department, update the client's medical record, and adjust the client's allergy arm band upon learning of the egg allergy.
Step-by-step explanation:
When a patient informs a nurse of a new allergy, such as an egg allergy, there are several important steps that should be taken immediately. First, it is crucial to notify the food services department of the allergy to prevent any meals containing eggs from being served to the client. Secondly, the allergy information must be entered into the client's medical record to ensure that all healthcare staff are aware of the allergy during treatment and care planning. Lastly, updating the client's allergy status on their allergy arm band is essential for immediate visual recognition of the allergy by any healthcare professional who comes in contact with the client. Misinformation, such as telling the client it's a mild reaction without proper assessment, is not appropriate under any circumstances. It's important to take allergies seriously, as they can lead to symptoms ranging from mild to life-threatening, such as anaphylactic shock, which requires immediate treatment with epinephrine.
