Colorado CNA Practice Exam

When a resident is transferred, discharged or dies, it is necessary for the unit to be completely cleaned and disinfected. This is because the unit has been used by a previous resident and there may be contamination present.

The other options are incorrect because they do not take into account the potential for contamination from a previous resident.

Option A, cleaning and disinfecting when the shift changes, may not be thorough enough as it only covers a specific time frame rather than an event.

Option B, cleaning and disinfecting once a week, also does not take into account the potential for contamination from a previous resident and may not be frequent enough to maintain a sanitary environment.

Option D, cleaning and disinfecting every morning, may be a good schedule for maintaining cleanliness but it may not cover the possibility of a previous resident leaving behind a contaminated environment.

Therefore, the best option is C, cleaning and disinfecting when a resident is transferred, discharged or dies, as it ensures a thorough and timely cleaning to prevent the spread of infection.
