The nurse is looking at a set of ABG's and notices a bicarbonate level of 30. What other change would the nurse expect to see in their lab values?
Chloride level would be decreed
Sodium level would be elevated
Magnesium level would be elevated.
Potassium level would be decreased
The Correct Answer is A
A. Chloride level would be decreased: Metabolic alkalosis is often associated with hypochloremia, especially when caused by vomiting or diuretics. However, hypokalemia is more clinically significant.
B. Sodium level would be elevated: Sodium levels are not directly affected by metabolic alkalosis.
C. Magnesium level would be elevated: Magnesium levels are not significantly altered in metabolic alkalosis.
D. Potassium level would be decreased: A bicarbonate level of 30 mEq/L indicates metabolic alkalosis. In alkalosis, hydrogen ions shift out of the cells, and potassium moves into the cells, leading to hypokalemia.

Correct Answer is D
Explanation
A. Respiratory Alkalosis: Would have high pH (>7.45) and low PaCO2 (<35 mmHg).
B. Metabolic Acidosis: Would have low pH and low HCO3 (<22 mEq/L).
C. Metabolic Alkalosis: Would have high pH and high HCO3 (>26 mEq/L).
D. Respiratory Acidosis: A low pH (<7.35) and high PaCO2 (>45 mmHg) indicate respiratory acidosis, which occurs due to hypoventilation, COPD, or respiratory failure. The bicarbonate (HCO3) is normal, meaning there is no metabolic compensation yet.
Correct Answer is D
Explanation
A. Magnesium sulfate: Magnesium sulfate is used for eclampsia and torsades de pointes, not for reducing shivering.
B. Kayexalate: This medication is used for hyperkalemia, not temperature control.
C. Acetaminophen: While useful for fever, acetaminophen does not stop shivering.
D. Diazepam: Shivering increases metabolic demand and body temperature. Diazepam (a benzodiazepine) is a muscle relaxant that helps control shivering in hyperthermic clients.
