the following? - Answer- CO2
The nurse is caring for a client with worsening respiratory acidosis. Which of these
interventions does the nurse anticipate if the client's condition continues to deteriorate?
- Answer- Mechanical Ventilation

to increase the production of: - Answer- HCO3-
A client tells the nurse that the client has been taking Alka-Seltzer (bicarbonate—
antacid) four times a day for the past 2 weeks for an upset stomach. Upon assessment
of the client, the nurse notes hyperactive reflexes, tetany, and mental confusion. Arterial
blood gases reveal pH 7.55; serum HCO3− 37 mEq/L (37 mmol/L). The nurse suspects
the client may be experiencing: - Answer- Metabolic Alkalosis

anticipate before acid--base balance is restored? - Answer- Dysrhythmias
A client has the following arterial blood gas (ABG) values: pH, 7.12; partial pressure of
arterial carbon dioxide (PaCO2), 40 mm Hg; and bicarbonate (HCO3-), 15 mEq/L.
These ABG values suggest which disorder? - Answer- Metabolic acidosis
