A Patient Admitted with a Fever of Unknown Origin Has
A patient admitted with a fever of unknown origin has orders for "blood cultures x 3." The nurse should inform the patient that this procedure involves:
1)Collecting three samples daily in the morning, with one venipuncture when other daily blood work is obtained.
2)Obtaining three samples from different sites, with each sample requiring venipuncture.
3)Obtaining sufficient blood to prepare three sets of culture vials with one venipuncture.
4)Using random specimens, collected at the time any other blood sample is obtained, to minimize the number of venipunctures required.
