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? o spray a disinfectant into the air o wash her hands after coughing o stay home until she is no longer coughing o go into an empty room to cough

Explanation:

When coughing into the hand, germs transfer to the hands. Washing hands after coughing removes these germs, preventing contamination when touching objects or others. Spraying disinfectant into the air isn't practical for personal cough etiquette. Staying home until no longer coughing is extreme, and going to an empty room to cough doesn't address hand - borne contamination. So the correct action to prevent contamination by touch is washing hands after coughing.

Answer:

Wash her hands after coughing
