A nurse is calculating the partial pressure of oxygen (PaO2) in the arterial blood of a pregnant client who is in her second trimester.
The nurse should use which of the following values as the normal range for PaO2 in pregnancy?
27 to 32 mmHg is too low for PaO2 and would indicate severe hypoxemia or low oxygen levels in the blood.
This is the normal range for PaO2 in pregnancy according to several sources. PaO2 is the partial pressure of oxygen in arterial blood and reflects the oxygenation of the blood. It is influenced by factors such as ventilation, perfusion, diffusion, and hemoglobin affinity.
500 to 700 mL is a measure of tidal volume, not PaO. Tidal volume is the amount of air that moves in and out of the lungs with each breath.
7 to 10 L/min is a measure of oxygen flow rate, not PaO. Oxygen flow rate is the amount of oxygen delivered to a patient through a device such as a nasal cannula or a mask.
95 to 105 mmHg.
This is the normal range for PaO2 in pregnancy according to several sources.
PaO2 is the partial pressure of oxygen in arterial blood and reflects the oxygenation of the blood.
It is influenced by factors such as ventilation, perfusion, diffusion, and hemoglobin affinity.
Choice A is wrong because 27 to 32 mmHg is too low for PaO2 and would indicate severe hypoxemia or low oxygen levels in the blood.
Choice C is wrong because 500 to 700 mL is a measure of tidal volume, not PaO.
Tidal volume is the amount of air that moves in and out of the lungs with each breath.
Choice D is wrong because 7 to 10 L/min is a measure of oxygen flow rate, not PaO.
Oxygen flow rate is the amount of oxygen delivered to a patient through a device such as a nasal cannula or a mask.
