nurse is assisting with the admission of a client who has mononucleosis. Which of the following isolation precautions should the nurse initiate?
A.
Airborne
B.
Droplet
C.
Contact
D.
Protective environment
The correct answer and Explanation is :
For a client with mononucleosis, the correct isolation precaution to initiate is B. Droplet.
Explanation:
Mononucleosis, often caused by Epstein-Barr virus (EBV), is primarily spread through saliva, but it can also be transmitted through respiratory droplets. This means that the virus can be present in droplets expelled when an infected person coughs or sneezes. Therefore, the primary mode of transmission is via these droplets, which is why droplet precautions are recommended.
Droplet Precautions involve the following measures:
- Wearing a Mask: Healthcare providers should wear a surgical mask when working within 3 to 6 feet of the patient to prevent inhaling droplets that might be expelled from the patient’s respiratory tract.
- Patient Masking: If the patient needs to be transported or leaves their room for any reason, they should wear a mask to minimize the risk of spreading droplets to others.
- Hand Hygiene: Proper hand washing or use of hand sanitizers is crucial to prevent the spread of droplets that might have come into contact with surfaces.
Why Not the Other Precautions?
- Airborne Precautions (A): These are used for infections transmitted through airborne particles that can remain suspended in the air for longer periods, such as tuberculosis or measles. Mononucleosis is not spread through airborne particles, so this precaution is unnecessary.
- Contact Precautions (C): These are used for infections spread through direct contact with the patient or contaminated surfaces, such as MRSA or C. difficile. Mononucleosis does not spread through direct contact with body fluids or surfaces.
- Protective Environment (D): This is used for patients with compromised immune systems, such as those undergoing bone marrow transplants, to protect them from environmental pathogens. It’s not applicable to a patient with mononucleosis.
In summary, droplet precautions are the most appropriate for managing a client with mononucleosis to effectively prevent the transmission of the virus through respiratory droplets.
