Normal range for oxygen saturation via pulse oximeter is?
Correct answer
D
Rationale
The correct answer is D (95-100%) because normal oxygen saturation levels in healthy individuals typically range between 95-100%. This range indicates that the blood is adequately oxygenated. Choice A (80-100%) is incorrect as an oxygen saturation level below 95% may indicate hypoxemia. Choice B (93-100%) is close but may be too conservative, missing some cases of mild hypoxemia. Choice C (90-100%) is too broad and may include cases of mild hypoxemia.
