During teaching about home care for conjunctivitis, what should the nurse instruct the parent of a school-age child?

The correct guidance in this scenario emphasizes the importance of maintaining hygiene to prevent the spread of conjunctivitis, commonly known as pink eye. Instructing the parent to separate the child's used washcloth from those of others is crucial because conjunctivitis is often contagious. By isolating personal items such as washcloths, the risk of transmitting the infection to others in the household or sharing spaces is reduced.

This practice not only helps contain the infection but also encourages good hygiene habits in children, which is vital for their health and that of their peers. Cleaning and using separate personal items are essential steps in managing the condition effectively, particularly in a school-age child who may have close contact with others.

Other options, while they may contain elements of care, do not address the prevention of spreading the infection or the appropriate use of medications in the same effective manner.
