What should be done if a client has a severe allergic reaction during a treatment?

In the event of a severe allergic reaction during a treatment, the most appropriate action is to call emergency services and provide first aid. A severe allergic reaction, also known as anaphylaxis, can escalate quickly and lead to life-threatening complications, such as difficulty breathing, swelling, or a drop in blood pressure.

Promptly calling emergency services ensures that professional medical assistance is on the way, which is critical for the client’s safety and well-being. While providing first aid, it is essential to monitor the client’s condition and be ready to help with any necessary emergency interventions, such as elevating their legs or performing CPR if they lose consciousness.

The other options do not adequately address the severity of the situation. Continuing with the treatment can exacerbate the reaction, while administering an antihistamine may not be sufficient for severe reactions and should only be done under medical guidance. Asking the client to breathe deeply is not a suitable response and does not provide the immediate medical support they need. Prioritizing the client’s safety through prompt emergency response is critical in such situations.
