Question: 1 / 400

When should the tourniquet be released while drawing blood for five collection tubes?

After two minutes

Within one minute

Releasing the tourniquet within one minute during blood collection is beneficial for several reasons. Firstly, prolonged constriction of blood vessels can lead to hemoconcentration, where the proportions of cells in the blood may increase disproportionately, potentially skewing the test results. This can especially affect tests requiring precise measurements, such as electrolytes or complete blood counts.

Releasing the tourniquet within this timeframe ensures that the blood flow remains steady and that the collected samples reflect the patient's actual physiological state. This practice promotes both ease of collection and accuracy in diagnostic results, making it the preferred choice among healthcare professionals during blood drawing procedures.

Maintaining this time limit helps to avoid complications associated with prolonged pressure on the veins, such as pain, potential damage to the veins, and increased risk of hematoma.
