What is a nurse's first action in a medical emergency?

Ensuring scene safety is the first action a nurse should take in a medical emergency. This step is crucial as it protects both the patient and the healthcare provider from potential hazards, such as electrical dangers, violence, or other environmental risks. By ensuring that the scene is safe, the nurse can proceed without putting themselves or bystanders at further risk, which could complicate the situation or lead to additional injuries.

Once the safety of the scene is confirmed, the nurse can then assess the patient's condition, call for additional help if necessary, and provide first aid. These subsequent actions are critical but cannot be effectively executed unless the environment is secure. Prioritizing safety allows nurses to perform their duties effectively and deliver care in a controlled and safe manner.
