Question

The nurse is caring for a patient admitted with the early stages of septic shock. The nurse assesses the patient to be tachypneic, with a respiratory rate of 32 breaths/min. Arterial blood gas values assessed on admission are pH 7.50, CO₂ 28 mm Hg, HCO₃ 26. Which diagnostic study result reviewed by the nurse indicates progression of the shock state?

Answer 1

Review the arterial blood gas values for alkalosis in septic shock.

Step-by-step explanation:

The nurse has assessed a patient with early stages of septic shock and is looking for a diagnostic study result that indicates progression of the shock state. In this case, the nurse should review the arterial blood gas values. The pH value of 7.50 indicates alkalosis, which can be seen in septic shock due to hyperventilation leading to respiratory alkalosis. The CO2 level of 28 mm Hg is lower than the normal range, further supporting respiratory alkalosis. The HCO3 level of 26 is within the normal range, suggesting no compensation has occurred.
