What will cause impaired test results and trauma during a capillary stick?

Under milking
Excessive pressure
Over milking
No wiping

The correct answer is: Over milking

During a capillary stick, the proper technique is to gently milk the finger to obtain a small amount of blood for testing. In this process, if there is "under milking" (Option A), there may not be enough blood collected for an accurate test result. On the other hand, if there is "excessive pressure" (Option B) applied during the capillary stick, it can cause trauma and discomfort to the finger, which can affect the test result and cause pain for the patient. Additionally, not wiping the finger before the capillary stick (Option D) can lead to contamination and inaccurate results. Therefore, the best option is "over milking" (Option C), which refers to obtaining too much blood during the test, causing a false and inaccurate result.
