While interviewing a family for the first time, the nurse notes that the mother takes charge of introducing everyone, relating that they've come to therapy because of the older son's acting-out behavior. The father and the three children nod but do not say anything. Which response would be most appropriate by the nurse immediately?
a. Acknowledge the older son first, because his behavior has been mentioned as problematic.
b. Acknowledge the father first, because he is the other parent.
c. Acknowledge the children first, because they may feel left out of the situation.
d. Acknowledge the mother first, because she seems to take the lead.
