The nurse is reviewing the client's following arterial blood gases: pH 7.33, PaCo2 47, HCO3 24. Which manifestation would the nurse expect the client to be experiencing with this imbalance?
Confusion
Kussmaul's Respirations
Seizures
Paresthesia in the extremities
The Correct Answer is A
A. Confusion: Respiratory acidosis (low pH + high PaCO2) leads to decreased oxygenation of brain tissues, causing confusion, drowsiness, and lethargy.
B. Kussmaul's Respirations: Seen in metabolic acidosis, not respiratory acidosis.
C. Seizures: Seizures are more common with alkalosis (high pH) due to neuronal excitability.
D. Paresthesia in the Extremities: More common in respiratory alkalosis due to calcium shifts.

Correct Answer is D
Explanation
A. Nocturia: Excessive nighttime urination, not decreased urine output.
B. Enuresis: Involuntary urination, commonly bedwetting in children.
C. Anuria: Severe lack of urine output (< 100 mL/24 hrs), which is worse than oliguria.
D. Oliguria: Oliguria is defined as urine output < 400 mL/24 hours. 250 mL in 24 hours qualifies as oliguria.
Correct Answer is A
Explanation
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.
