A nurse is calculating the protein needs of a client who is a physical trainer.

The client weighs 220 lb and requires an increase of protein by 2.0 g/kg/day.

The client has taken 0.8 g of protein/kg/day in the past.

How much total protein/day should the nurse recommend?

The correct answer is © 280 g of protein/day.

Choice A reason: This choice suggests that the client needs 80 g of protein/day. However, this is not correct because the client’s weight is 220 lb (which is approximately 100 kg), and they require an increase of protein by 2.0 g/kg/day. This means they need an additional 200 g of protein per day. Adding this to their past intake of 0.8 g/kg/day (which is 80 g/day), the total comes to 280 g/day.

Choice B reason: This choice suggests that the client needs 120 g of protein/day.  The client’s total protein requirement per day is more than this.

Choice C reason:

Given:

- The client's weight is 220 lb.

- The client requires an increase of protein by 2.0 g/kg/day.

- The client has taken 0.8 g of protein/kg/day in the past.

We know that 1 kg = 2.2 lbs. So, we first need to convert the client's weight from lbs to kg.

Step 1: Convert the client's weight from lbs to kg

220 lb ÷ 2.2 lb/kg = 100 kg

Next, we calculate the increased protein requirement.

Step 2: Calculate the increased protein requirement

100 kg × 2.0 g/kg/day = 200 g/day

Then, we calculate the past protein intake in g/day.

Step 3: Calculate the past protein intake

100 kg × 0.8 g/kg/day = 80 g/day

Finally, we add the past protein intake to the increased protein requirement to get the total protein/day the nurse should recommend.

Step 4: Calculate the total protein/day

200 g/day + 80 g/day = 280 g/day

Choice D reason: This choice suggests that the client needs 400 g of protein/day. However, this is not correct because it exceeds the client’s total protein requirement per day, which is 280 g/day.
