Final answer:
The patient obtained 360 kilocalories from the lunch.
Step-by-step explanation:
To calculate the number of kilocalories obtained from the lunch, we need to know the energy content of each food item. According to the provided information, a serving of skinless chicken provides 190 Calories, broccoli has negligible calories, an apple contains around 80 calories, and a cup of nonfat milk has around 90 calories.
By adding up the calories from each food item in the lunch, we get: 190 Calories (chicken) + 0 Calories (broccoli) + 80 Calories (apple) + 90 Calories (milk) = 360 Calories. So, the patient obtained 360 kilocalories from the lunch.
