Why must fingernail polish be removed prior to surgery?

• A. It poses a risk of allergic reactions
• B. It will interfere with oxygen level assessment
• C. It could stain surgical instruments
• D. It affects surgical aesthetic

Answer: (B)

The removal of fingernail polish prior to surgery is crucial primarily because it can interfere with the assessment of oxygen levels in a patient's body. Surgical teams routinely monitor peripheral oxygen saturation using pulse oximetry, a non-invasive method often implemented using a sensor that attaches to a fingertip. If the fingernails are painted, particularly with dark or opaque polish, it can obstruct the sensor's ability to accurately measure oxygen levels, potentially leading to misinterpretation of the patient's respiratory status. Ensuring clear visibility of the nail beds allows for more accurate monitoring, which is essential for evaluating the patient's oxygenation during and after surgery. This proactive measure helps in preventing complications that may arise from undetected hypoxia, thus maintaining patient safety throughout the surgical procedure.
