The patients who require the least help from staff are evacuated first. This includes those who can walk unassisted and are not attached to equipment. Therefore, the individual with the prosthetic leg is evacuated first; although the patient is receiving antibiotics, the question does not indicate if he is currently receiving them. The second patient to be evacuated is the individual who ambulates with a cane and requires oxygen. Then, the individuals who are mobile via wheelchairs are evacuated. The patient with paraplegia does not have IV access or an active infection, so this patient is moved before the one with tuberculosis. The next patient to be moved is the morbidly obese individual who is confined to a bed because of the femoral catheterization that occurred 2 hours ago. The last patient to be moved is the 4-year-old who is intubated, sedated, and chemically paralyzed.

Correct Order:

• 32-year-old patient who ambulates with a prosthetic leg and is receiving intravenous antibiotics
• 71-year-old patient who ambulates with a cane and requires oxygen via nasal cannula
• 44-year-old patient with paraplegia who has a stage 3 pressure ulcer on the right ischial spine
• 51-year-old patient with active tuberculosis who has a central line and uses a wheelchair because of a pelvic fracture
• 28-year-old patient with a BMI of 64 who underwent a cardiac catheterization via the femoral artery 2 hours ago
• 4-year-old patient with bronchiolitis who is chemically paralyzed, sedated, and intubated
