Final answer:
The nurse should explain to Ms. Harrison that caloric needs generally decrease around age 50, with average daily requirements between 1500 to 2000 calories depending on various factors. It is highlighted that even a slight excess in calories can result in weight gain over time, and the importance of balancing calorie intake with physical activity for weight management.
Step-by-step explanation:
When explaining to Ms. Harrison about caloric intake, the nurse should convey that caloric needs generally decrease around age 50. This is due to changes in metabolism and often a decrease in physical activity levels. On average, a person needs 1500 to 2000 calories per day to sustain daily activities. The specific calorie intake needed varies based on factors including body mass, age, gender, activity level, and exercise frequency. An excess of just 200 calories per day can lead to significant weight gain over time, adding an extra pound every 18 days or approximately 20 pounds over a year.
For weight management, it is crucial to balance calories consumed with calories burned through exercise. This balance helps prevent weight gain which can occur from a sedentary lifestyle combined with high caloric intake. Ms. Harrison should be aware that running or jogging a mile burns roughly 100 calories.
Although the nurse can provide general advice based on average needs, it is important for Ms. Harrison to understand that individual caloric needs can vary widely. Factors such as whether someone is more sedentary or physically active play a significant role in determining their unique caloric requirements.
