NHA Phlebotomy Certification Practice Exam

What issue can arise from failing to let alcohol dry on the patient's arm after cleansing?

1. Increased bacteriostatic action

2. A stinging sensation for the patient

3. A possible unsterile site

4. Specimen hemolysis

The correct answer is: Increased bacteriostatic action

Failing to allow the alcohol to dry on the patient's arm after cleansing can lead to a stinging sensation for the patient. When alcohol is applied to the skin, it not only acts as an antiseptic but also evaporates quickly. If the skin is still wet with alcohol at the time of needle insertion, this residual moisture can cause a burning or stinging sensation due to the penetration of alcohol into the skin. While alcohol does have bacteriostatic properties when it is applied, allowing it to air dry is important because it ensures proper disinfection without causing discomfort. Inadequate drying can also potentially contribute to complications such as a non-sterile site, as the alcohol hasn’t properly evaporated, which can interfere with the phlebotomy process. Lastly, not properly cleansing or drying can even affect specimen quality, potentially leading to hemolysis if alcohol contaminates the blood sample. In summary, allowing the alcohol to dry is crucial for minimizing patient discomfort and ensuring a proper sterile procedure, which is reflected in the significance of carefully following this step in phlebotomy protocols.
