Why are capillary blood gases less desirable than arterial bloood gases (ABG's)
-
Skin puncture blood contains tissue fluid
-
The blood is exposed to air during collection
-
Skin puncture blood is only partial arterial
-
All of the above
Correct Answer
A. Skin puncture blood is only partial arterialExplanation
Capillary blood gases are less desirable than arterial blood gases because skin puncture blood, which is obtained from capillaries, is only partially arterial. Arterial blood is considered the gold standard for assessing oxygen and carbon dioxide levels in the blood because it directly reflects the gas exchange happening in the lungs. Capillary blood, on the other hand, contains a mixture of arterial and venous blood, which may not accurately represent the gas exchange happening in the lungs. Therefore, arterial blood gases are preferred over capillary blood gases for more accurate and reliable assessment of respiratory function.Rate this question:
