In order to evaluate a patient's acid-base balance,the primary provider has prescribed diagnostic tests to measure pH,PCO2,and HCO3 - .The nurse realizes that the patient will:
A) Have a venous blood sample drawn
B) Have an arterial blood sample taken
C) Need to provide a fresh voided urine sample
D) Need to provide a 24-hour urine sample
Arterial Blood Sample
A sample of blood taken from an artery that is often used to measure gases, such as oxygen and carbon dioxide, in the blood.
Acid-Base Balance
The mechanism by which the body maintains its blood pH within the narrow range necessary for optimal enzyme function and metabolic processes.
- Evaluate and decipher arterial blood gases (ABGs) and understand their significance in patient management.

Final Answer :
B
Explanation :
Evaluation of serum pH,PCO2,and HCO3- requires a sample of arterial blood.It is possible to measure the pH in the urine,but not the other values.Venous blood provides diagnostic information on the various electrolytes (e.g.,sodium,potassium),BUN,creatinine,and hematocrit.Venous bicarbonate can be measured,as well.
