The nurse is reviewing the patient's arterial blood gas results. The PaO₂ is 96 mm Hg, pH is 7.20, PaCO₂ is 55 mm Hg, and HCO₃ is 25 mEq/L. What might the nurse expect to observe on assessment of this patient?

Question

Quizplus · Accepted Answer

The patient is experiencing respiratory acidosis ($\downarrow$pH and $\uparrow$PaCO₂) which may be manifested by disorientation, tremors, possible seizures, and decreased level of consciousness. Tachycardia and decreased blood pressure are not characteristic of a problem of respiratory acidosis. Increased anxiety and hyperventilation will cause respiratory alkalosis, which is manifested by an increase in pH and a decrease in PaCO₂.
