Question 1 of 5
Normal range for oxygen saturation via pulse oximeter is?
Correct Answer: D
Rationale: The correct answer is D (95-100%). Normal oxygen saturation levels are typically between 95-100%, indicating sufficient oxygen in the blood. Levels below 95% may indicate hypoxemia.
Choice A (89-100%) includes a lower boundary below the normal range.
Choice B (100%) is too narrow, not accounting for slight fluctuations.
Choice C (90-100%) allows for lower levels than the standard minimum of 95%.
Therefore, D is the most accurate range for normal oxygen saturation levels on a pulse oximeter.
