The school nurse is trying to prevent the spread of a flu virus through the school. Which infection-control strategies can be employed to prevent the spread of the flu virus?
1. Teaching parents safe food preparation and storage
2. Withholding immunizations for children with compromised immune systems
3. Sanitizing toys, telephones, and door knobs to kill pathogens
4. Separating children with infections from children who are well
5. Teaching children to wash their hands after using the bathroom
Correct Answer: 3,4,5
Rationale: To prevent the spread of communicable diseases, microorganisms must be killed or their growth controlled. Sanitizing toys and all contact surfaces, separating children with infections, and teaching children to wash their hands all control the growth and spread of microorganisms. Teaching parents safe food preparation and storage is another tool to prevent the spread of microorganisms but is not related to the flu virus. Immunizations should not be withheld from immunocompromised children; this is not an infection-control strategy.
