Final answer:
In phlebotomy, as per CLSI/NCCLS guidelines, the phlebotomist should verify the patient's diet and medication before a venipuncture to ensure accurate test results.
Step-by-step explanation:
According to CLSI/NCCLS guidelines, prior to performing a venipuncture, the phlebotomist must verify the patient's diet and medication. Verification of medication is essential because certain drugs can affect laboratory test results, which may lead to inaccurate diagnostic information.
For example, anticoagulants could alter the results of clotting tests, while certain medications can affect blood glucose levels. It is the responsibility of the phlebotomist to ensure that the test results are as accurate as possible by considering factors that could influence these results. This includes understanding how the patient's diet and medication may impact the composition of their blood. It is equally important that the patient's identification is confirmed, and their understanding of the procedure is assured.
When intravenous fluids are required for a dehydrated human patient, they are typically given a balanced electrolyte solution or saline to rehydrate and maintain fluid balance.
