Wheelchair scale reads 192 lb; chair weighs 43 lb. Resident weight =:

Rationale

Resident weight = 149 lb.

To find the resident's weight, subtract the weight of the chair from the total weight shown on the wheelchair scale. The calculation is 192 lb (total weight) - 43 lb (chair weight), resulting in a resident weight of 149 lb.

A (235) YOUR ANSWER

This choice incorrectly adds the weight of the chair to the scale reading without performing the necessary subtraction. The total weight should not exceed the scale reading; hence 235 lb is not a valid answer.

B (199) YOUR ANSWER

This option suggests a weight that is also higher than the scale reading. Adding the chair weight to the scale reading leads to confusion, but the correct method requires subtraction to arrive at the actual resident weight.

C (149) CORRECT

This is the correct calculation: 192 lb (scale reading) minus 43 lb (chair weight) equals 149 lb. This option accurately reflects the resident's weight after accounting for the chair.

D (129) YOUR ANSWER

Choosing 129 lb implies an incorrect subtraction of the chair's weight from the total. If performed correctly, 192 lb - 43 lb equals 149 lb, not 129 lb, making this answer invalid.

Conclusion

To determine the resident's weight using a wheelchair scale, the weight of the chair must be subtracted from the total weight displayed. In this case, the resident weighs 149 lb, calculated by accurately subtracting the chair's weight from the scale reading. Any other options either miscalculate or misinterpret the procedure required to arrive at the correct answer.
