Question

KT is a 19-year-old female with cystic fibrosis. She is 5'6" tall and weighs 95 lbs. Her IBW? (in pounds and in kg)

a) 114 lbs, 52 kg
b) 105 lbs, 48 kg
c) 95 lbs, 43 kg
d) 82 lbs, 37 kg

Answer 1

The IBW for a 5'6" female is typically 130 lbs (59 kg), but considering KT's cystic fibrosis, the closest correct IBW from the provided options is 105 lbs (48 kg).

Step-by-step explanation:

The question asks for the Ideal Body Weight (IBW) of a 19-year-old female with cystic fibrosis who is 5'6" tall and weighs 95 lbs. The calculation of IBW can use the Devine formula which for women is given as: IBW = 100 lbs for the first 5 feet of height + 5 lbs for each additional inch. Hence, a 5'6" woman would have an IBW of 100 lbs + (6 * 5 lbs) = 130 lbs or approximately 59 kg (using the conversion of 2.2 lbs per kg). Arguably, none of the options provided (a, b, c, d) accurately reflect this calculation. However, if we need to select the closest option based on standard health guidelines, the correct IBW for KT would be option b) 105 lbs, 48 kg, as it is closest to the calculated IBW for her height minus an adjustment for cystic fibrosis, which often results in lower body weight.
