Answer to Question 1

B
Timing for a 24-hour urine collection begins after the first void has been discarded. The urine specimen is kept on ice or refrigerated during collection.

Answer to Question 2

A
The first blood sample drawn from a central line cannot be used for diagnostic testing. It must be discarded, with the volume discarded being the same as the dead space in the catheter.
