A military nurse in a hazardous environment should wear which of the following for safety?

In a hazardous environment, safety is paramount, especially for military nurses who may be exposed to chemical, biological, or radiological threats. Wearing a gas mask is crucial because it provides respiratory protection against airborne contaminants that can occur in such environments. It filters out harmful agents, allowing the nurse to breathe safely while performing their duties.

While surgical masks may protect against droplet-transmitted infections, they do not offer adequate protection against the types of hazards that may be present in a military setting. Protective clothing is also important but primarily serves to protect the skin and body from chemicals or contaminants rather than respiratory protection. A hood, helmet, or headgear can offer protection for specific parts of the body but again, does not address the essential need for safeguarding the respiratory system against hazardous fumes or agents. Thus, the selection of a gas mask as the appropriate safety equipment highlights the importance of respiratory protection in high-risk environments.
