Final answer:
Factors that can affect the reading of the SpO2 oximeter include improper alignment, client motion, jaundice, nail polish, outside light sources, peripheral vascular diseases, and hypothermia. These factors can interfere with the accuracy of the oximeter readings and lead to erroneous results.
Step-by-step explanation:
Factors that can affect the reading of the SpO2 oximeter include improper alignment, client motion, jaundice, nail polish, outside light sources, peripheral vascular diseases, and hypothermia. These factors can interfere with the accuracy of the oximeter readings and lead to erroneous results. For example, improper alignment of the oximeter sensor can cause inaccurate readings, while jaundice and nail polish can affect the absorption of light by hemoglobin.
