RN stands for registered nurse. RNs are very different from LPNs. The amount of schooling and education is longer for an RN. RNs usually go through two to four year programs at community colleges and universities. They graduate with a BSN (Bachelor's of Science In Nursing) or an ADN (Associate's Degree In Nursing).
It is important to understand what causes it in your home so you can protect your family from the dangers of carbon monoxide poisoning. Never unplug or remove the battery to silence a CO detector or CO alarm. You may go back to sleep and suffer the deadly consequences of carbon monoxide poisoning. At the very least, ventilate the area and change the detector's battery. Always assume the worst for your own safety.
If you have symptoms that you think could be caused by carbon monoxide poisoning, leave the area right away, and call or go to the emergency room. If you keep breathing the fumes, you may pass out and die. Carbon monoxide poisoning can occur suddenly or over a long period of time. Breathing low levels of carbon monoxide over a long period can cause severe heart problems and brain damage. See a doctor if: You often are short of breath and have mild nausea and headaches when you are indoors.
