"I need to carry the Epi-pen with me at all times": Individuals with severe allergies should always have an Epi-pen in case of exposure to allergens. No reinforcement needed.
"When my Epi-pen reaches its expiration date, I need to get a new one": Epi-pens have a limited shelf life, and using an expired pen may be ineffective. No reinforcement needed.
"Once I inject myself with my Epi-pen, I won't have to go to the hospital": Epinephrine provides temporary relief, but further medical evaluation is essential due to the risk of a biphasic reaction or persistent symptoms. Reinforcement needed.
"I need to avoid all foods that may have been exposed to peanuts": Strict avoidance of allergens is essential to prevent severe reactions. No reinforcement needed.
