Editing Reduction of Risk Potential – LPN Practice Questions (section)

==Question 10==
The nurse is collecting a 24-hour urine specimen. Which action is correct?
# Save the first voiding at the start of the collection period.
# Discard the first voiding, then collect all urine for the next 24 hours, ending with a final voiding at the exact end time.
# Collect only the daytime voidings and estimate the overnight volume.
# Store the container at room temperature in the client's bathroom.

'''Answer:''' Option 2. Discard the first voiding, then collect all urine for the next 24 hours, ending with a final voiding at the exact end time.

''Rationale:'' The bladder must be empty when timing starts, so the first specimen is discarded and the clock begins. Every subsequent voiding is saved, and the client is asked to void at the exact end time so that specimen is included. If any voiding is accidentally discarded, the collection must be restarted. The container is usually kept refrigerated or on ice as required by the laboratory, which makes option 4 incorrect.
