Final answer:
A possible source of carbon monoxide exposure that the nurse should include is a gas-powered stove.
Step-by-step explanation:
One possible source of carbon monoxide exposure that the nurse should include is a gas-powered stove. When gas is burned, it releases carbon monoxide, which is a toxic gas. If a gas stove is not properly adjusted, it can emit even more carbon monoxide.
Other sources of carbon monoxide exposure can include faulty chimneys, gas-powered generators, and burning charcoal. These sources can release carbon monoxide indoors and can be extremely dangerous to human health.
