The nurse is asking an adolescent about illicit substance abuse. The adolescent answers, "Yes, I've used marijuana at parties with my friends." What is the next question the nurse should ask?

A) "Who are these friends?"
B) "Is this a regular habit?"
C) "Do your parents know about this?"
D) "When was the last time you used marijuana?"

If a patient admits to the use of illicit substances, then the nurse should ask, "When was the last time you used drugs?" and "How much did you take that time?" The other questions may be considered accusatory and are not conducive to gathering information. Asking the person who the friends are, if it's a regular habit, and if the parents know about it can be considered accusatory and are not conducive to gathering necessary information. Instead, if a patient admits to the use of illicit substances, the nurse should ask, "When was the last time you used drugs?" and "How much did you take that time?"
