A nurse is admitting a school-age child who has bacterial meningitis. Which of the following types of isolation precautions should the nurse initiate?
A.
Contact
B.
Airborne
C.
Protective environment
D.
Droplet
The Correct Answer and Explanation is:
The correct answer is D. Droplet.
Explanation:
Bacterial meningitis, especially in the case of pathogens like Neisseria meningitidis, is primarily transmitted via respiratory droplets. Therefore, droplet precautions are crucial in preventing the spread of infection to others.
Droplet Precautions are specifically designed to protect against pathogens that are transmitted through large respiratory droplets. These droplets are typically expelled during coughing, sneezing, talking, or other activities that expel air from the respiratory tract. Droplet precautions include:
- Wearing Masks: Healthcare workers should wear a surgical mask when within close proximity (usually within 3 feet) of the infected patient. This helps to block the transmission of droplets that may contain the infectious agent.
- Patient Room: The patient should be placed in a private room if possible, or if a private room is not available, they can be placed in a room with other patients who have the same infection. The room should ideally have proper ventilation, and doors should remain closed.
- Hand Hygiene: Frequent hand washing or use of hand sanitizer is essential to reduce the risk of cross-contamination.
- Proper Disposal of Contaminated Materials: Any materials that become contaminated with respiratory secretions, such as tissues, should be disposed of properly, and surfaces should be cleaned and disinfected regularly.
Contact Precautions are used for infections that are spread through direct contact with the patient or their environment, such as MRSA or C. difficile, which is not the case for bacterial meningitis. Airborne Precautions are used for diseases transmitted through tiny airborne particles, such as tuberculosis or measles, which are smaller than the droplets involved in bacterial meningitis. Protective Environment is for patients with severely compromised immune systems, like those undergoing bone marrow transplants, and is not appropriate for bacterial meningitis.
In summary, for a school-age child with bacterial meningitis, droplet precautions are the appropriate type of isolation to implement to prevent the transmission of the infection to others.
