Final answer:
To convert 195 lbs to kilograms, divide by the conversion factor of 2.205, resulting in 88.43537 kg. We round this to the nearest tenth, considering the significant figures, to get 88.4 kg.
Step-by-step explanation:
To convert the patient's weight from pounds to kilograms, we use the conversion factor where 1 kg is equivalent to 2.205 pounds. Starting with the patient's weight of 195 lbs, we divide by the conversion factor:
Weight in kg = Weight in lbs / Conversion factor
Weight in kg = 195 lbs / 2.205
This gives us an initial calculation of 88.43537 kg. However, since we must consider significant figures, we need to round our answer to the least precise measurement given in the problem. The patient's weight is expressed in a non-decimal form, so we do not have a specified number of decimal places to guide us. However, the conversion factor is specified to three decimal places, thus we should round our answer to the nearest tenth to match the precision, yielding a final result of 88.4 kg.
