A nurse is using the World Health Organization definition of health to provide care. Which area will the nurse focus on while providing care?

A) Obtain a bedside commode for the client's use: While a bedside commode may be helpful for reducing the need for the client to walk to the bathroom, it may not fully address the client's concern about falling. The most immediate solution to improve safety during the night would be ensuring that the environment is adequately lit and easy to navigate. The bedside commode could be considered, but a nightlight would be the first step.

B) Leave a nightlight on in the client's room: This is the best action to take in this situation. A nightlight will improve visibility and help the client navigate safely to the bathroom at night. Falls are more common in low-light environments, and a nightlight can provide the needed illumination to reduce the risk of tripping or losing balance during the night.

C) Limit the client's fluid intake in the evening: While limiting fluid intake may reduce the frequency of nighttime trips to the bathroom, it is not an ideal or holistic solution. Reducing fluid intake can also lead to dehydration, which can cause other health issues. The focus should be on creating a safe environment for the client to move about, rather than restricting essential fluids.

D) Put the side rails up and tell the client to call the nurse before voiding: Raising the side rails can increase the risk of entrapment and restrict the client's ability to move freely if they need to get out of bed. Telling the client to call the nurse may also delay their ability to respond to their needs promptly, especially in the middle of the night. Instead, ensuring a safer environment and encouraging independence, with appropriate safety measures like a nightlight, is more effective.

A) Use a dosimeter to measure the level of radiation in the area before intervening:
While a dosimeter can be useful for measuring radiation levels, it is not the immediate priority in a mass casualty incident. The nurse's first concern should be to ensure personal safety by choosing the most appropriate PPE based on the unknown nature of the hazard. Delaying action to measure radiation might delay critical intervention for victims.

B) Wait until the type of equipment needed is known:
Waiting to determine the exact type of personal protective equipment (PPE) is not a safe strategy in a mass casualty incident. The nurse should be prepared to act quickly to provide care, and waiting to ascertain PPE could jeopardize both the nurse's safety and the safety of the victims. Immediate action, even with the highest available PPE, is more important than waiting for full details.

C) Choose the highest level of protection equipment available:
In a mass casualty incident where the type of hazard is unknown, choosing the highest level of protection ensures the nurse is safeguarded against a broad range of potential risks, such as chemical, biological, or radiological exposure. This action prioritizes safety while providing the flexibility to intervene without delay.

D) Decontaminate victims before intervening:
While decontamination is crucial in a hazardous incident, the nurse's first responsibility is their own safety. Without the proper PPE, the nurse could become contaminated. After donning the appropriate protective equipment, the nurse can then assist with decontaminating victims if necessary. Decontaminating victims should not be the first step before ensuring the nurse is properly protected.
