What is the ideal body weight of a 42-year-old female who is 5'5" tall? Optional hint: IBW = (height in inches)2 × 0.0313
Derived from the BMI calculation: 703 × (IBW in lb ÷ ht in inches2) = 22."How to Estimate and Evaluate %UBW and %IBW" in the text defines IBW as the weight at which the patient will have a BMI of 22.

To calculate the ideal body weight (IBW) using the optional hint:
Height in inches = 5'5" x 12 inches/foot = 65 inches
IBW = (65)^2 x 0.0313 = 132 pounds

Therefore, the ideal body weight for a 42-year-old female who is 5'5" tall is 132 pounds. The answer is C. Using the provided formula, IBW for a 5'5" female would be:
(65 inches)2 × 0.0313 = 124.5 pounds
However, the question asks for the "ideal body weight" which is defined as the weight at which the patient will have a BMI of 22.
Using the BMI formula (703 × weight in lbs ÷ height in inches2) and solving for the weight that would result in a BMI of 22:
703 × (weight ÷ 65 inches2) = 22
Weight = 22 × 65 inches2 ÷ 703 = 132 pounds
Therefore, the ideal body weight of a 42-year-old female who is 5'5" tall is 132 pounds, which is choice C.
