A patient has just returned from a radiology test that included an IV injection of dye. The nurse collects the blood specimen and notes the radiographic test and time it was performed on the requisition form. Why did the nurse do this?
  1. To inform the lab of possible adulterants.
  2. To inform the lab of a procedure that may affect the blood test.
  3. To inform the lab of other departments involved in the patients care.
  4. To inform the lab of possible time delays.
Explanation
Answer: B - The nurse noted on the requisition form the name and time of the radiographic procedure because the IV dye may interfere with the blood test. The clinical laboratory relies on the nurses to provide information that may affect the results of a test. The lab techs would not know this without the aid of the nurse.
