A nurse is admitting a client who has pertussis. Which of the following types of transmission-based precautions should the nurse initiate?

A. Airborne:
Airborne precautions are used for infections transmitted via small droplet nuclei that remain suspended in the air for long periods and can be inhaled by others. Examples of diseases requiring airborne precautions include tuberculosis, measles, and chickenpox. Pertussis is not transmitted via the airborne route.

B. Contact:
Contact precautions are used for infections spread by direct or indirect contact with the client or their environment. Examples include Clostridioides difficile, methicillin-resistant Staphylococcus aureus (MRSA), and vancomycin-resistant enterococci (VRE). Pertussis is primarily spread through respiratory droplets rather than contact with contaminated surfaces.

C. Droplet:
Pertussis is primarily spread through respiratory droplets when an infected person coughs or sneezes. The nurse should initiate droplet precautions to prevent the transmission of the bacteria to others. These include wearing a surgical mask when within 3 feet of the client, placing the client in a private room or cohorting with another client who has the same infection, and ensuring that visitors wear masks and practice hand hygiene.

D. Protective:
Protective precautions, also known as reverse isolation, are used to protect clients who have compromised immune systems from exposure to pathogens. This precaution is not relevant for a client with pertussis; instead, the focus is on preventing transmission to others through droplet precautions.

A) Severity: When the nurse asks the client to rate the pain on a scale of 0 to 10, they are assessing the severity of the pain. This component of the PQRST mnemonic focuses on understanding the intensity or severity of the pain experienced by the client. By asking the client to quantify their pain on a scale, the nurse gains insight into how much the pain is affecting the client's well-being and can use this information to guide pain management interventions.
B) Precipitating cause: This component of the PQRST mnemonic involves identifying factors that trigger or worsen the pain. Asking about activities or events that preceded the onset of pain helps the nurse understand the precipitating cause.
C) Region: This component involves identifying the specific location or region of the body where the pain is experienced. It helps the nurse localize the pain and identify potential underlying causes.
D) Quality: This component involves asking the client to describe the characteristics or quality of the pain, such as sharp, dull, stabbing, or burning. Understanding the quality of the pain provides additional information about its nature and possible underlying mechanis
