The client's arterial blood gas sample reveals pH 7.32, PaCO2 48 mm Hg, and HCO3– 22. Which does the nurse implement?
1. Instruct client to breathe into a paper bag.
2. Activates the emergency resuscitation team.
3. Instructs the client to cough and deep breathe.
4. Gives the client sodium bicarbonate by mouth.
3
3. The client has respiratory acidosis, so the nurse instructs the client to cough and deep breath to facilitate gas exchange in the lungs and exhalation of carbon dioxide. The client has respiratory acidosis because the pH is below 7.35 (acidosis) and the respiratory component of ABGs is abnormal at 48 mm Hg (high indicating acidosis); thus, because the components both indicate acidosis, the client's acidosis is respira-tory.
1. Breathing into a paper bag can increase the PaCO2.
2. The emergency team is not necessary.
4. Administering an alkaline agent by mouth is ineffective treatment for respiratory acidosis.
