Causes of Disease

Question 2 • 2026-2027 EDGE Human Anatomy and Physiology A

Select the ways patients and their visitors and caregivers can help break the chain of infection in healthcare facilities.

Answer

learn about the risks for infection specific to the treatment the patient is receiving

wash hands every two hours while in the patient’s room

ask healthcare professionals to wash their hands or use hand sanitizer if they were not observed washing up

avoid visiting hospitals entirely during the four months that make up the cold and flu season

Explanation

Patients and visitors can help prevent infection by learning about risks related to the patient’s treatment and by speaking up if healthcare professionals have not cleaned their hands. Thus, A and C are correct. Hand hygiene should be performed at appropriate times, such as before and after patient contact, rather than simply every two hours, so B is not correct. Avoiding all hospital visits throughout the entire cold and flu season is not a practical infection-prevention measure, so D is not correct.
