Question

multiple choice question
sarala has been practicing good cough etiquette and covering her mouth with her hand when she coughs. although this may prevent others from contracting an illness through the air, she must still do what to prevent contamination by touch?
○ spray a disinfectant into the air
○ wash her hands after coughing
○ go into an empty room to cough
○ stay home until she is no longer coughing

Explanation:

The question is about preventing contamination by touch after coughing into one's hand. Spraying disinfectant into the air doesn't target touch - related contamination. Going to an empty room to cough or staying home until no longer coughing are not directly related to preventing touch - based contamination after coughing into the hand. Washing hands after coughing removes the germs from the hands that could cause touch - based contamination.

Answer:

Wash her hands after coughing
