A client diagnosed with varicella two days ago has open vesicles. What precaution sign will the nurse place on the door?

Choice A rationale Contact precautions are required for a client with open varicella (chickenpox) vesicles because the fluid within these lesions contains the Varicella Zoster Virus (VZV), which can be transmitted through direct contact with the lesions or indirectly via contaminated surfaces. These precautions include wearing a gown and gloves when entering the client's room to prevent this type of transmission. Choice B rationale Airborne precautions are also essential for a client with varicella, as the Varicella Zoster Virus is highly contagious and can be spread through small aerosolized viral particles that remain suspended in the air and travel long distances. This requires the client to be placed in an Airborne Infection Isolation Room (AIIR) and the nurse to wear an N95 or higher-level respirator mask upon entry. Choice C rationale Droplet precautions are used for diseases transmitted by larger respiratory droplets (like influenza) that typically travel only short distances (about 3 to 6 feet) before falling, which is not the primary mode of transmission for the highly aerosolized Varicella Zoster Virus. While some droplets may be produced, the airborne transmission risk is much greater and necessitates a higher level of isolation. Choice D rationale Standard precautions are the minimum infection prevention practices applied to the care of all patients regardless of suspected or confirmed infection status, primarily focusing on hand hygiene and personal protective equipment (PPE) use based on anticipated exposure to body fluids. Varicella requires isolation measures beyond basic standard precautions due to its high contagiousness and airborne transmission risk.
