Which of the following actions should the nurse identify as an indication that the teaching was effective? (Select All that Apply.)

The correct answers are A, D, and E. A is correct because when the parent applies the prescribed medication as instructed, it shows understanding of the teaching. D is correct because developing a plan to have the child use ear plugs in the shower demonstrates proactive behavior to prevent infection. E is correct because noticing purulent drainage and reporting it to the surgeon promptly indicates understanding of potential complications. Choices B and C are incorrect because allowing the child to lift their older sibling and enforcing nose blowing are not necessarily indications of effective teaching.
