The patient has new-onset restlessness and confusion. Pulse rate is elevated, as is respiratory rate. Oxygen saturation is 94%. The nurse ignores the pulse oximeter reading and calls the health care provider for orders because the pulse oximetry reading is inaccurate. Which factors can cause inaccurate pulse oximetry readings? (Select all that apply.)
A) O2 saturations (SaO2) > 70%
B) Carbon monoxide inhalation
C) Hypothermic fingers
D) Intravascular dyes
E) Nail polish
F) Jaundice
Pulse Oximetry Readings
Measurements obtained with a pulse oximeter, indicating the oxygen saturation level of the blood.

The act of breathing in carbon monoxide gas, which can lead to poisoning due to its ability to displace oxygen in the blood, potentially causing fatal health effects.
Intravascular Dyes
Colorful substances injected into the vascular system to enhance the visualization of structures and processes during medical imaging techniques.
