A client's arterial blood gas (ABG) reads: pH 7.18, PaCO2 54 mm Hg, HCO3 26 mEq/L. What condition does the nurse recognize may contribute to the development of this result? Normal values: pH: 7.35-7.45, PaCO2: 35-45 mm Hg, HCO3: 22-26 mEq/L

Prolonged vomiting

COPD

Chronic renal failure

Anxiety and hyperventilation

Answer and Explanation

The Correct Answer is B

Choice A reason: Prolonged vomiting typically leads to metabolic alkalosis due to the loss of gastric acid, which is not consistent with the ABG results showing acidosis.

Choice B reason: COPD can lead to respiratory acidosis, as indicated by the elevated PaCO2 and low pH in the ABG results, making it a likely contributor to these findings.

Choice C reason: Chronic renal failure can lead to metabolic acidosis, but the HCO3 level is within the normal range, which does not support this as the primary condition.

Choice D reason: Anxiety and hyperventilation usually result in respiratory alkalosis due to the excessive exhalation of CO2, which is the opposite of what the ABG results show.

Correct Answer is C

Explanation

Choice A reason: While assessing temperature is important for monitoring infection, it is not the immediate priority in the treatment of UTI and sepsis.

Choice B reason: Monitoring urine output is crucial for a UTI but does not address the systemic infection that sepsis represents.

Choice C reason: Administering antibiotics is the most critical intervention for a client with sepsis due to a UTI, as it directly addresses the underlying infection and can be life-saving.

Choice D reason: Evaluating the current CBC is important for understanding the client's baseline and response to infection but is secondary to the administration of antibiotics.

A. Uncompensated metabolic alkalosis B. Uncompensated respiratory acidosis C. Uncompensated metabolic acidosis D. Uncompensated respiratory alkalosis

Correct Answer is A

Explanation

Choice A reason: The ABG results show an elevated pH and HCO3, which are indicative of metabolic alkalosis. The PaCO2 is within the normal range, suggesting that it is uncompensated.

Choice B reason: Respiratory acidosis would be indicated by an elevated PaCO2 and a decreased pH, which is not the case here.

Choice C reason: Metabolic acidosis would be indicated by a decreased pH and HCO3, which is not consistent with the given results.

Choice D reason: Respiratory alkalosis would be indicated by a decreased PaCO2 and an increased pH, which is not consistent with the given results.
