If a dialysis patient weighs 156.2 pounds on arrival and 69 kg upon leaving, what is the weight gain in kilograms?

To determine the weight gain in kilograms for the dialysis patient, you first need to convert the initial weight from pounds to kilograms to facilitate a direct comparison with the weight at discharge.

The weight of the patient upon arrival is 156.2 pounds. To convert pounds to kilograms, you can use the conversion factor where 1 pound equals approximately 0.453592 kilograms.

Calculating that gives:

156.2 pounds × 0.453592 kg/pound = approximately 70.85 kg.

Now we can assess the weight difference:

• Initial weight in kilograms: approximately 70.85 kg

• Final weight upon leaving: 69 kg

To find the weight gain, we subtract the final weight from the initial weight:

70.85 kg - 69 kg = approximately 1.85 kg.

When considering normal rounding, the closest number to this difference that matches the answer choices provided would be rounded to 2.0 kg. Thus, the weight gain in kilograms is indeed about 2.0 kg, which aligns with the provided selection. This is why the option indicating a weight gain of 2.0 kg is the correct choice.
