Final answer:
The nurse should inform the parent that one possible sign of marijuana use in a teenager is increased hunger, especially for 'junk' food. Other signs include bloodshot eyes, impaired coordination, and changes in mood or behavior.
Step-by-step explanation:
The nurse should inform the parent that one possible sign of marijuana use in a teenager is increased hunger, especially for 'junk' food. This is due to the effect of marijuana on the brain, which can stimulate appetite. However, it is important to note that this is not a definitive indicator of marijuana use and other signs and symptoms should be considered as well.
Other possible signs of marijuana use include bloodshot eyes, slowed reaction time, impaired coordination, and changes in mood or behavior. Slurred speech and appearing unsteady on the feet can also be possible signs.
It is important for the parent to have an open and non-judgmental conversation with their child if they suspect marijuana use, and to seek professional help if needed.
