Which of the following is not a typical part of a code blue response?

• A. Administer antihistamines
• B. Begin CPR
• C. Call for help
• D. Apply AED

Answer: (A)

Code blue responses focus on rapid assessment and life-support actions to restore circulation and breathing. The essential steps are calling for help, starting high-quality CPR, and using an AED to deliver a shock if needed. Antihistamines don’t address the immediate needs of a cardiac or respiratory arrest and aren’t used to restart the heart or secure the airway during resuscitation. In cases like anaphylaxis, treatments such as epinephrine and airway management are used, but routine antihistamines aren’t a primary part of the code blue sequence. So administering antihistamines isn’t part of a typical code blue response.
