The client has just returned from OR with respirations of 8 per minute. What set of ABG's would the nurse expect to see?

A.

pH 7.30. PaCO2 38 P02 92, HCO3 15

B.

pH 7.32. PaCO2 56, PO2 84, HCO3 26

C.

pH 7.37. PaCO2:45, PO2 91, HCO3 24

D.

pH 7.48. PaCO2 32, PO2 94. HCO3 22

Answer and Explanation

The Correct Answer is B

A. pH 7.30, PaCO₂ 38, HCO₃ 15: Metabolic acidosis (low HCO₃, normal PaCO₂).

B. pH 7.32, PaCO₂ 56, PO₂ 84, HCO₃ 26: The client has respirations of 8/min, which indicates hypoventilation → CO₂ retention → respiratory acidosis. pH 7.32 indicates acidosis. PaCO₂ 56 mmHg - Elevated CO₂ (hypercapnia), confirming respiratory acidosis. HCO₃ 26- Normal bicarbonate suggests that compensation has not yet occurred

C. pH 7.37, PaCO₂ 45, HCO₃ 24:  Normal ABG values.

D. pH 7.48, PaCO₂ 32, HCO₃ 22: Respiratory alkalosis (low PaCO₂ due to hyperventilation, not hypoventilation).

Correct Answer is ["1370"]

Explanation

To calculate total output, we sum all recorded outputs:

  • Urine output:
    • 400 mL + 350 mL = 750 mL
  • Chest tube drainage:
    • 175 mL (current) - 155 mL (previous) = 20 mL
  • Nasogastric tube drainage: 575 mL
  • Jackson-Pratt drain output: 25 mL

Total Output = 750 + 20 + 575 + 25 = 1,370 mL

Correct Answer: 1,370 mL

Correct Answer is B

Explanation

A. Serum potassium 4.8 mmol/L: This is a normal potassium level (3.5–5.0 mmol/L) and indicates successful treatment.

B. Serum glucose 58 mg/dL: IV insulin drives potassium into cells, lowering serum potassium. However, insulin also lowers blood glucose, which can lead to hypoglycemia (glucose <70 mg/dL). Hypoglycemia is the primary adverse effect of IV insulin therapy.

C. Serum sodium 138 mEq/L: This is a normal sodium level (135–145 mEq/L) and not an adverse effect.

D. Calcium level of 100 mg: Calcium is not directly affected by IV insulin therapy.
