Which phrase exemplifies a proper method of confirming understanding with a patient?

Choosing the phrase "What will you tell your wife about the food she buys?" is effective because it engages the patient in a conversation that encourages them to articulate their understanding of the information provided. This method, often referred to as “teach-back,” allows healthcare professionals to assess the patient’s comprehension in a way that is direct and relevant to their personal context.

When patients explain information in their own words, it helps healthcare providers confirm what the patient has understood and identify any gaps in knowledge. This approach not only reinforces the patient’s learning but also fosters a more personal connection, encouraging them to communicate openly.

The other options, while they may seem helpful, are less effective for confirming understanding. Asking "Do you understand?" or "Are you following along?" can lead to superficial affirmations without truly gauging the patient's comprehension. The phrase "Explain this to me" doesn’t give the patient a chance to express what they’ve learned; instead, it places the demand on them to clarify something that may not have been fully understood. These methods do not facilitate an interactive dialogue in the same way that asking a patient to describe their plans in the context of their personal life does.
