Question 1 of 5
A client has the following laboratory values: a pH of 7.55 an HCO3 level of 22 mEq/L and a PaCO2 of 30 mmHg. Which action would the nurse plan to take?
Correct Answer: D
Rationale: The correct answer is D: Encourage the client to slow down breathing. Given the client's values of pH 7.55, HCO3 22 mEq/L, and PaCO2 30 mmHg, this indicates respiratory alkalosis.
To correct respiratory alkalosis, the nurse should encourage the client to slow down breathing to retain more CO2, which will increase PaCO2 levels and help normalize pH. Administering IV normal saline (choice
A) would not address the underlying cause of respiratory alkalosis. Performing Allen's test (choice
B) assesses collateral circulation in the hand and is unrelated to the client's condition. Encouraging the client to increase breathing (choice
C) would exacerbate respiratory alkalosis.
