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) 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.

A) Foot drop: Foot drop is a common complication associated with impaired physical mobility. It occurs when the muscles responsible for lifting the front of the foot become weak or paralyzed, often due to prolonged immobility or neurological impairment. The nurse should monitor for this condition and implement preventive measures like using ankle-foot orthoses (AFOs) to support the foot in a neutral position and promote proper alignment.

B) Increased socialization: While it is important to encourage socialization and support mental health, increased socialization is not a complication associated with impaired mobility. In fact, patients with impaired mobility are more likely to experience social isolation, not increased socialization. Therefore, the nurse should focus on strategies to encourage social interaction to prevent feelings of loneliness and depression.

C) Somnolence: Somnolence, or excessive sleepiness, is not directly related to impaired physical mobility. While some patients with severe illness or conditions may experience somnolence, it is not a common complication of immobility. Instead, the nurse should focus on monitoring for complications like respiratory issues or skin breakdown.

D) Hypostatic pneumonia: Hypostatic pneumonia is a complication that can occur when a patient remains in a supine or immobile position for an extended period. The lack of movement and deep breathing can lead to pooled secretions in the lungs, which increases the risk of infection. The nurse should monitor for signs of respiratory distress and encourage frequent position changes, deep breathing, and coughing exercises to reduce the risk.

E) Impaired skin integrity: Impaired skin integrity is a major concern in patients with impaired mobility. Prolonged pressure on bony prominences due to immobility can lead to pressure ulcers (bedsores). The nurse should monitor the skin regularly, implement pressure-relieving devices, and reposition the patient frequently to prevent skin breakdown.
