Wireless Handheld Computers Used to Scan a Bar Code on the Patient's

Multiple Choice

Wireless handheld computers used to scan a bar code on the patient's identification band reduce preexamination variables in the routine venipuncture process because:

A) patient identification can be verified by scanning requisitions before leaving the laboratory for the inpatient units.
B) labels for all patient collection tubes may be printed in batches ahead of each collection on the patient floors, thus freeing up laboratory printers for other tasks.
C) labels for a specific patient are generated only after the patient's identification has been correctly verified by scanning his or her identification band and not printed ahead of time.
D) the bar code on the patient's driver's license may be scanned for outpatients instead of scanning a wrist band.
