Question

Which of the following would be appropriate for a client with arterial blood gas (ABG) values of pH 7.5, PaCO2 26 mm Hg, O2 saturation 96%, HCO3- 24 mEq/L, and PaO2 94 mm Hg?____

a. Instruct the client to breathe into a paper bag.
b. Provide oxygen therapy to increase oxygen levels.
c. Assist the client in slowing down their breathing rate.
d. Administer a bronchodilator medication.

Answer 1

For a client with ABG values indicating respiratory alkalosis, the appropriate action is to assist in slowing down their breathing rate, as this would allow CO2 levels to rise and correct the alkalosis.

Step-by-step explanation:

A client with arterial blood gas (ABG) values of pH 7.5, PaCO2 26 mm Hg, O2 saturation 96%, HCO3- 24 mEq/L, and PaO2 94 mm Hg is showing signs of respiratory alkalosis, which is indicated by the elevated pH and the decreased PaCO2. Considering the ABG results and the physiological basis for carbonic acid control in the respiratory system, an appropriate intervention for this patient would be to assist the client in slowing down their breathing, or in other words, to promote hypoventilation to allow CO2 levels to rise and correct the alkalosis. The options of breathing into a paper bag, providing oxygen therapy, or administering a bronchodilator are not suitable interventions based on these ABG values.

Rebreathing into a paper bag is a classic response to hyperventilation; however, without signs of panic or hyperventilation, this intervention may not be appropriate. Oxygen therapy is not indicated as the O2 saturation is already at 96%, and there is no need to increase it further. A bronchodilator is generally used to treat airway constriction, which is not an issue in this case, as indicated by the normal O2 saturation and PaO2.
