Acid/Base Balance

Which finding in a patient's arterial blood gas result indicates a normal blood pH level?

pH value of 7.42

The nurse is providing patient teaching to a patient with metabolic acidosis. What statement should the nurse include in her teaching?

"Metabolic acidosis is any acidosis not due to a respiratory issue."

Ron's blood gas results reveal the following: pH 7.38, CO2 40 and HCO3 25.

Complete Compensation All values are within normal stated range.

Metabolic acidosis is indicated by which arterial blood gas result?

Decreased serum pH and bicarbonate levels

The nurse is caring for a patient with respiratory alkalosis. What nursing interventions would the nurse expect to include? Select all that apply.

Encouraging slow, deep breathing Providing emotional support Assisting with activities of daily living

Which statements are accurate with regard to acid-base imbalances? Select all that apply.

Hypoventilation results in respiratory acidosis. Increase in bicarbonate levels is associated with alkalosis. Oxygen saturation is not used to evaluate acid-base balance.

A patient's diagnostic test results indicate an increased anion gap. Based on this finding, what would the nurse anticipate that the patient's lab results may also reveal?

Increased ketone and lactic acid levels

Which treatment method would be used for a patient who is exhibiting respiratory acidosis?

Insertion of chest tube

The renal buffering system provides acid-base compensation by:

Limiting excretion of hydrogen ions via urine output.

Jennifer's blood gas results reveal the following: pH 7.50, CO2 40 and HCO3 30.

Metabolic Alkalosis In metabolic alkalosis, one would expect to see increased pH levels representative of alkalosis and increases in the bicarbonate level.

Amanda's blood gas results reveal the following: pH 7.25, CO2 35 and HCO3 18.

Metabolic acidosis These blood gases indicate pH acidemia, a normal CO2 level, and a decreased HCO3 level. A metabolic acidosis state is indicated by the decreased pH and bicarbonate levels. Carbon dioxide is the respiratory component and is within normal range.

Jessica's blood gas results reveal the following: pH 7.24, CO2 50 and HCO3 27.

Partial Compensation While the pH is outside of normal range indicating acidemia, the carbon dioxide response is increased while bicarbonate is slightly increased, indicating an attempt to bring the pH value back to normal.

Kirk's blood gas results reveal the following: pH 7.18, CO2 50 and HCO3 25.

Respiratory Acidosis In respiratory acidosis, one would expect to see decreased pH levels representative of acidemia and increased carbon dioxide levels.

Oxygen saturation of arterial blood is used to primarily evaluate which of the following?

Respiratory function

What are the component parts of an arterial blood gas? Select all that apply.

Serum pH levels Bicarbonate level Carbon dioxide level Oxygen
