A dialysis patient's weight on arrival is 156.2 pounds. What is the weight gain in kilograms if the leaving weight was recorded as 69 kg?

To determine the weight gain of the dialysis patient in kilograms, it is essential to first convert the arriving weight from pounds to kilograms, and then compare it to the leaving weight recorded in kilograms.

The arriving weight is given as 156.2 pounds. To convert pounds to kilograms, you can use the conversion factor where 1 pound is approximately equal to 0.45359237 kilograms:

156.2 pounds × 0.45359237 kg/pound = approximately 70.799 kg.

Subsequently, the weight gain can be calculated by subtracting the leaving weight from the arriving weight:

Weight gain = Arriving weight (in kg) - Leaving weight (in kg)

Weight gain = 70.799 kg - 69 kg = 1.799 kg.

When rounding this to one decimal point, we can consider it approximately a 1.8 kg gain, which aligns closely with the choice of a 2.0 kg gain.

Thus, the correct choice reflects a minimal yet significant weight gain, which is typical in dialysis patients due to fluid retention between treatments. This understanding is crucial for monitoring patient health and managing dialysis effectively, as it impacts treatment decisions and potential adjustments in fluid management.
