Why might Don Johnson be admitted to the stepdown unit?

The rationale for why Don Johnson might be admitted to the stepdown unit primarily revolves around the need for a transition from intensive care. The stepdown unit is specifically designed for patients who have made satisfactory progress in their recovery and are stable enough not to require the constant, high-level monitoring provided in an intensive care setting.

When a patient like Don is deemed stable, it indicates that he has shown significant improvement in his condition and his medical needs can be met with less intensive monitoring. This allows healthcare providers to continue delivering necessary medical care while preparing the patient for eventual transfer to a lower level of care or rehabilitation, if necessary.

The other choices may explain situations that could occur but are not the primary reasons for a stepdown unit admission; for instance, while lack of available burn units may lead to other placements, it does not justify the stepdown unit specifically. Similarly, while medical care and monitoring are part of the function of stepdown units, the key factor is the patient's stability, which is the main driver for admission.
