use of PPE, including an N95 mask or powered air purifying respirators (PAPRs)
Numbers 3, 4, 5, and 6 are correct.
Airborne precautions are used for infections caused by organisms that may remain airborne for extended periods, such as tuberculosis and measles. Standard precautions apply to all clients as all body fluids, moist membranes, and excretions are potentially infectious. Negative airflow rooms exchange air and discharge room air to the outside or through HEPA filters. N95 masks or PAPRs prevent inhalation of contaminated air. Fall precautions may or may not be needed for this client. Droplet precautions are used for infections caused by organisms that travel 3 feet but are not suspended for long periods of time, such as mumps and influenza.
