A nurse is reviewing the ABG values of a client. The client has a pH of 7.2, PaCO2 of 60 mm Hg, and HCO3 of 25 mEq/L. The nurse should identify that the client has which of the following acid-base imbalances?
Respiratory alkalosis
Metabolic alkalosis
Respiratory acidosis
Metabolic acidosis
The Correct Answer is C
A. Incorrect. The client does not have respiratory alkalosis because respiratory alkalosis is characterized by a low PaCO2 (less than 35 mm Hg) and a high pH (greater than 7.45).
B. Incorrect. The client does not have metabolic alkalosis because metabolic alkalosis is characterized by a high HCO3 (greater than 26 mEq/L) and a high pH (greater than 7.45).
C. Correct. The client has respiratory acidosis because respiratory acidosis is characterized by a high PaCO2 (greater than 45 mm Hg) and a low pH (less than 7.35).
D. Incorrect. The client does not have metabolic acidosis because metabolic acidosis is characterized by a low HCO3 (less than 22 mEq/L) and a low pH (less than 7.35).

Correct Answer is {"dropdown-group-1":"B","dropdown-group-2":"D"}
Explanation
The client is at highest risk for developing hypocalcemia as evidenced by the total calcium level of 8.0 mg/dL (normal range 9.0 to 10.5 mg/dL).
Explanation:
After a total thyroidectomy, there is a risk of hypocalcemia due to potential damage or removal of the parathyroid glands, which regulate calcium levels in the body. The laboratory result indicating a total calcium level of 8.0 mg/dL, which is below the normal range, supports this risk. Hypocalcemia can lead to symptoms such as tingling, muscle cramps, or more severe complications like cardiac arrhythmias if not addressed promptly.
Correct Answer is ["18"]
Explanation
The client weighs 198 lb, which is equivalent to (198 ÷ 2.2 = 90kg.
Therefore, the amount of mannitol for the test dose is 0.2 g/kg x 90 kg = 18 g.
The nurse should administer 18 g of mannitol IV bolus over 5 min as a test dose to the client who has severe oliguria.
