The client presents to the unit with complaints of shortness of breath. A tentative diagnosis of respiratory acidosis related to pneumonia is made. Which finding would support this diagnosis?
- A. $\mathrm{pH}$ of $7.45, \mathrm{CO}_2$ of $45, \mathrm{HCO}_3$ of 26
- B. $\mathrm{pH}$ of $7.35, \mathrm{CO}_2$ of $46, \mathrm{HCO}_3$ of 27
- C. $\mathrm{pH}$ of $7.34, \mathrm{CO}_2$ of $30, \mathrm{HCO}_3$ of 22
- D. $\mathrm{pH}$ of $7.44, \mathrm{CO}_2$ of $32, \mathrm{HCO}_3$ of 25
Correct Answer: B
Rationale: Respiratory acidosis is characterized by a low pH (<7.35) and elevated CO₂ (>45 mmHg) due to impaired gas exchange, as in pneumonia. Option B (pH 7.35, CO₂ 46, HCO₃ 27) is closest to this profile, with slight compensation. Options A, C, and D show normal or alkalotic pH or low CO₂.

- C. Contact the health care provider to clarify the prescription for iron sucrose.
- D. Hold erythropoietin and inform the health care provider of the laboratory test results.
