Final answer:
Pineapple is identified by the nurse as part of the Clean 15 list, which features produce with low pesticide residue making it safer to consume non-organically.
Step-by-step explanation:
The nurse identifies pineapple as being among the produce types listed in the Clean 15.
The Clean 15 list includes fruits and vegetables that have the least pesticide residue and are considered safe to consume in their non-organic form.
