The nurse should follow airborne precautions for clients with illnesses that spread through airborne transmission. Tuberculosis (TB), measles, and chickenpox are examples of airborne-transmitted infections. Streptococcal pharyngitis is a disease that is spread by droplets. Hence, the nurse would follow droplet precautions for clients with streptococcal pharyngitis. The nurse would follow contact precautions for clients with illnesses that spread through contact transmission. Examples of illnesses that spread by contact transmission include drug-resistant gastroenteritis; respiratory, skin, and wound infections; hepatitis A; herpes simplex virus; impetigo; scabies; and pediculosis. Clients who must be protected from the outside environment and need to be shielded from others' microorganisms are kept in protective isolation.
