Which nursing action has the highest priority for a teenager admitted with burns to 45% of the body?

Maintain aseptic technique.

Explanation:

Aseptic techniques involves following the practices and procedures that prevents or reduces contamination by pathogens. A burn patient can have his protective upper skin layer removed, exposing the vulnerable inner skin layer. The inner skin layer is susceptible to infection, and if infected, can lead to further medical complication, which might even end up fatal. Aseptic technique involves the use of barrier to minimize contact between the patient and the medical personnel. Such barriers includes sterile gloves , sterile gowns , masks for the patient and healthcare personnel, and  sterile drapes . Sterile barriers should not have touched contaminated surface, and should be prepacked and sealed. Medical instruments should be sterilized too.
