A 24 hr. urine specimen (total volume = 1,136 mL) is submitted to the lab for quantitative urine protein. Calculate the amount of protein excreted per day, if the total protein is 52 mg/dL.

Explanation:
To find the daily protein excretion, multiply the concentration by the total urine volume, making sure the units align. Convert the volume from milliliters to deciliters: 1,136 mL equals 11.36 dL. Then multiply: 52 mg/dL × 11.36 dL = 590.72 mg. Rounding gives about 591 mg per day. This matches the given option, since mg/day = mg/dL × dL.
