Before performing venipuncture, a phlebotomy technician should ask the patient about their fasting status, if applicable. Which of the following best explains the importance of this question?
- ATo verify the patient's identity against their dietary records.
- BTo ensure the patient is comfortable and not lightheaded during the procedure.
- CTo assess if the patient is compliant with their doctor's overall instructions.
- DTo determine if the patient has followed dietary restrictions for accurate test results.
Show answer & explanationAnswer & explanation
Correct answer: D. To determine if the patient has followed dietary restrictions for accurate test results.
Many laboratory tests, such as glucose and lipid panels, require the patient to fast for a specific period. Failure to fast can significantly alter test results, leading to misdiagnosis or inappropriate treatment.
Why the other options are wrong
- A. Fasting status is unrelated to patient identification.
- B. While comfort is important, it's not the primary reason for asking about fasting status.
- C. Assessing overall compliance is not the direct purpose of this specific question, though it might be a secondary benefit.
Fasting Status Verification
Confirming whether a patient has abstained from food and drink (except water) for a specified period before certain lab tests.
- Essential for accurate glucose and lipid tests.
- Prevents erroneous results.
- Directly impacts patient diagnosis and treatment.
