An effective way to ensure the exlusion of children who are ill is to institute a policy for

a-frequent hand washing
b-standard precautions
c-mandatory immunizations
d-daily health checks

D is correct. Because, daily health check ups are to ensure that the child/children are safe and healthy. A and D are good answers, but D i s a better answer. Hand washing only gets the germs off of your hands. So, D health check ups is the correct answer. Hope this helps!

Pretty sure this would be b. the rest are trick questions. the bystanders  won't go near you if u have cpr cuffs that could hurt them. the dog will back off because the sound will scare him. and the vomits just a stupid trick. if there is that much slober and vomit on the guy hes either choking on it, or just take off his shirt.
