QUESTION

A client is demonstrating signs of hypoxia. What laboratory value will help the nurse determine the clients' degree of effective gas exchange?

ANSWER: Arterial blood gas (ABG) analysis

Hypoxia is a condition in which the patient has extremely low oxygen supply in the body tissue or cells. Hypoxia is a common manifestation of those who suffer from respiratory diseases like chronic obstructive pulmonary diseases (COPD) and pneumonia.

One of the laboratory values that the nurse must monitor is the patient's ABG result. ABG provides data that assesses the lungs' ability to provide adequate oxygen (PaO2) and to remove carbon dioxide from the body (PaCO2). These two variables are significant in determining the degree of effective gas exchange and if the patient has adequate ventilation.

In addition, ABG analysis also provides data regarding the acid-base balance of the blood. You may encounter the terms like pH level, metabolic, alkalosis, and acidosis, but I won't discuss them further since it is somehow irrelevant to the question asked. Nevertheless, here are the normal laboratory values for ABG as a reference ^_^

I hope it helps!
