Which of the Following is Most Likely to Cause Hypoxemia

Question

Which of the following is most likely to cause hypoxemia?
A) Kussmaul respirations
B) Hyperventilation
C) Medullary depression
D) Brain stem stimulation

Accepted Answer

Medullary depression can result in decreased respiratory rate and depth, leading to inadequate oxygenation of the blood and hypoxemia. Kussmaul respirations and hyperventilation are both compensatory mechanisms that increase respiratory rate and depth to improve oxygenation. Brain stem stimulation may also increase respiratory rate and depth, improving oxygenation.
