NHSA Module 5 Practice Test

A Code Blue is a medical emergency signaling cardiac or respiratory arrest, so the action that fits best is to activate the emergency response and begin life-saving measures right away. Starting CPR immediately maintains blood flow to vital organs, and following ACLS per protocol provides the structured steps for advanced care, including rhythm assessment, defibrillation if indicated, airway management, and appropriate medications. This rapid, coordinated response gives the patient the best chance of returning to a survivable heartbeat. Scheduling routine alarm checks or only doing vitals won’t address the urgent need for resuscitation and can waste precious seconds. Transporting the patient to another ward delays critical care, which is why it’s not appropriate during a Code Blue.
