The nurse is caring for a 65-year-old Mr. Y who was admitted 1 week ago after his family found him confused and unable to ambulate in his home. Upon admission, he weighed 150 lb; today, he weighs 140 lb
The nurse knows that determining his percent weight change can help to determine his current nutritional status. What is his percent weight change? A) 3% B) 5% C) 7% D) 9%
C
Feedback:
To determine the percent weight change, subtract the current body weight from the usual body weight and multiple by 100, and then divide by the usual body weight. The answer will be the percent weight change. Because Mr. Y's admission weight is 150 lb and his current weight is 140 lb, the equation would be (150 – 140) × 100 / 150 = 6.666666666667 or 7%. This would indicate a significant weight loss.
