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. 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. Constipation: Hypocalcemia causes diarrhea, while hypercalcemia causes constipation.
B. Negative Trousseau’s sign: A positive Trousseau’s sign (carpal spasm during BP cuff inflation) is expected with hypocalcemia.
C. BP of 180/88: Severe hypocalcemia may cause hypotension, not hypertension.
D. Numbness and tingling of the extremities: Hypocalcemia can occur after a total thyroidectomy due to accidental removal or damage to the parathyroid glands. Neuromuscular excitability, including paresthesia (numbness and tingling), tetany, and muscle spasms, are classic signs.
