Question

the key to preventing mrsa is:

○ proper nutrition

○ preventive antibiotics

○ wearing long sleeves

○ good hand hygiene

Explanation:

MRSA (Methicillin - Resistant Staphylococcus Aureus) is a type of bacteria that can cause infections. The spread of MRSA is often through contact, especially via hands. Good hand hygiene (like washing hands properly or using hand sanitizers) helps to remove or kill the bacteria on hands, thus preventing its spread. Proper nutrition is more related to overall health and immunity but not the key prevention method for MRSA. Preventive antibiotics are not recommended as a general prevention method for MRSA as it can lead to antibiotic resistance. Wearing long sleeves does not prevent the spread of MRSA as the bacteria is spread through contact, not mainly through exposure of arms.

Answer:

D. good hand hygiene
