Questions: Question 7. Dentures are expensive. When brushing dentures what should be placed in the bottom of the sink as cushion in case they are dropped? Water is sufficient A washcloth on the bottom covered with 3-4 inches of water Foam cushions None of the above

The answer is the second one: A washcloth on the bottom covered with 3-4 inches of water.

Explanation for each option:

1. Water is sufficient: While water can provide some cushioning, it may not be enough to prevent damage if the dentures are dropped. The impact on a hard surface can still cause them to break.

2. A washcloth on the bottom covered with 3-4 inches of water: This option provides a soft surface (the washcloth) to absorb the impact and water to further cushion the fall. This combination is effective in minimizing the risk of damage to the dentures.

3. Foam cushions: While foam cushions could provide a soft landing, they are not typically used in a sink setting for this purpose. They may not be practical or readily available in a bathroom environment.

4. None of the above: This option is incorrect because there is a recommended method (the washcloth and water) that provides adequate protection.

In summary, placing a washcloth on the bottom of the sink and covering it with 3-4 inches of water is the best practice to cushion dentures in case they are dropped while brushing.
