What this question is testing
Objective: Patient education on solutions
Prompt focus: A contact lens wearer should be instructed never to do which of the following with their lens storage case?
Why the correct answer works
Top off old solution by adding new solution to used solution
Correct. Wearers should never top off old solution by adding new solution to it.
Why the tempting wrong answer fails
The tempting wrong answer usually loses because it skips the key condition, priority, or evidence in the prompt.
Plain-language takeaway
Topping off, meaning adding fresh solution to old used solution, reduces disinfection effectiveness and increases infection risk; cases should be emptied and refilled with fresh solution each time.
Simple analogy
Think of patient education on solutions like following a short checklist: identify the clue, confirm the rule, and then make the move that fits this exact scenario.
