Question

Which statement is true regarding hypoxemia?

1) hypoxemia results in the increased oxygenation of arterial blood
2) respiratory alterations cause hypoxemia
3) hypoemia results in the decreased oxygenation of tissue cells
4) various system changes cause hypoxemia

Answer 1

Hypoxemia is caused by respiratory alterations, leading to a decreased oxygen level in the blood and reduced oxygenation of tissue cells. The correct option is 2.

Step-by-step explanation:

Hypoxemia refers to a lower-than-normal level of oxygen in the blood. The correct statement regarding hypoxemia is option 2) respiratory alterations cause hypoxemia. When there are changes or abnormalities in the respiratory system, such as impaired lung function or inadequate ventilation, it can lead to a decreased oxygen level in the blood. This can have negative effects on the oxygenation of tissue cells throughout the body. Hence, 2 is the correct option.
