ATI Fundamental Exam Chapter 25 Candile Questions

Extract:


Question 1 of 5

The nurse is caring for a client with respiratory insufficiency. The arterial blood gas (ABG) results indicate a pH of 7.50 and a PaCO2 of 30 mm Hg and the nurse concludes that the client is experiencing respiratory alkalosis. Which additional laboratory value would the nurse expect to note in this client?

Correct Answer: D

Rationale: The correct answer is D: Potassium level of 3.0 mEq/L. In respiratory alkalosis, there is a decrease in PaCO2 levels leading to a shift in hydrogen ions causing hypokalemia. Potassium levels drop as hydrogen ions move into cells in exchange for potassium ions to maintain electroneutrality.
Therefore, the nurse would expect a low potassium level in this client.
A: Sodium level is not directly related to respiratory alkalosis.
B: Magnesium level is not directly related to respiratory alkalosis.
C: Phosphorus level is not directly related to respiratory alkalosis.
