The patient is on a ventilator. The health care provider has indicated concern about the patient's acid-base status. The nurse anticipates that the health care provider will determine the acid-base levels via:
a. PaO2 measurement.
b. SaO2 levels.
c. chloride levels.
d. arterial blood gas analysis.
D
Arterial blood gas (ABG) analysis is an effective method of evaluating acid-base balance and oxygenation. PaO2 is the partial pressure of oxygen in arterial blood. When PaO2 is within normal range, it has no primary role in acid-base regulation. SaO2 is the percentage of hemoglobin molecules that are carrying as much oxygen as is possible (saturated). SaO2, however, has no di-rect effect on acid-base balance. Hypochloremia is abnormally low blood chloride level. Hyper-chloremia is an abnormally high blood chloride level, which occurs with some types of acidosis, some renal conditions, and other electrolyte imbalances. Neither has unique signs and symptoms.
