Colorado CNA Practice Exam

When must a unit be completely cleaned and disinfected?

1. When the shift changes

2. Once a week

3. When a resident is transferred, discharged, or dies

4. Every morning

The correct answer is: When a resident is transferred, discharged, or dies

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.
