Step 1:: Write down the conversion factor between pounds and kilograms.
1~\text{pound} = 0.453592~\text{kilogram}
The conversion factor is:
Step 2:: To convert the patient's weight from pounds to kilograms, multiply the weight in pounds by the conversion factor.
140~\text{pounds} \times 0.453592~\frac{\text{kilograms}}{\text{pound}} = 63.50288~\text{kilograms}
Step 3:: Since we cannot have a fraction of a kilogram as an answer, we need to round the result to the nearest whole number.
In this case, rounding to the nearest whole number gives us 64 kilograms.
Final Answer
So, the correct answer is option B.
