While the doctor explains a diagnosis to a patient, the patient has a confused look on his face. What should the doctor do to ensure effective communication?

Tell the patient not to worry about it and to just take the medication.

Ignore the nonverbal cue, and continue with the confusing diagnosis.

Ask if the patient understands, and if they don’t, explain it again in different terms.

Cross his arms to show the patient that he does not have the time to go through everything he said again.
