A nurse is reinforcing teaching with a client about reducing dietary caffeine intake. The nurse should remind the client that 240 mL (8 oz) of which of the following beverages contains the least amount of caffeine?

A) Hot cocoa: Hot cocoa contains the least amount of caffeine compared to the other beverages listed. While it does contain some caffeine, it is significantly lower than coffee, tea, or cola. A typical 8 oz serving of hot cocoa contains approximately 3-10 mg of caffeine, making it the best option for a client looking to reduce caffeine intake. B) Brewed green tea: Brewed green tea contains more caffeine than hot cocoa. On average, an 8 oz cup of brewed green tea contains about 25-30 mg of caffeine, which is more than cocoa but less than coffee or cola. Although green tea has health benefits, it may not be the best option for those trying to limit caffeine intake. C) Instant coffee: Instant coffee typically contains more caffeine than brewed green tea or hot cocoa. An 8 oz serving of instant coffee can contain around 30-90 mg of caffeine, depending on the brand and how it is prepared. While it provides a caffeine boost, it is not a good choice for someone seeking to reduce caffeine consumption. D) Cola soft drink: Cola soft drinks contain a moderate amount of caffeine, usually about 30 mg per 8 oz serving. While this is less than coffee or tea, it still contains more caffeine than hot cocoa and could be a concern for someone trying to cut back on caffeine.
