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.
The risk of carbon monoxide poisoning increases after disasters when gasoline- or diesel-powered generators may be more frequently used to supply power. When home generators were used to supply electricity after Hurricane Ike, one child died and 15 other children were injured as a result of carbon monoxide poisoning. The CDC recognizes this hazard and offers Clinical Guidance for Carbon Monoxide Poisoning After a Disaster.
