The client has just returned from OR with respirations of 8 per minute. What set of ABG's would the nurse expect to see?
pH 7.30. PaCO2 38 P02 92, HCO3 15
pH 7.32. PaCO2 56, PO2 84, HCO3 26
pH 7.37. PaCO2:45, PO2 91, HCO3 24
pH 7.48. PaCO2 32, PO2 94. HCO3 22
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 {"dropdown-group-1":"A","dropdown-group-2":"C"}
Explanation
Respiratory acidosis- Due to opioid-induced respiratory depression (hypoventilation, CO₂ retention). Hypervolemia: IVF at 150ml/hr is a relatively high rate for someone with CHF. Even isotonic fluids like 0.9% sodium chloride can accumulate quickly and worsen cardiac workload.
Incorrect answers:
- Metabolic alkalosis: typically occurs due to vomiting or excessive bicarbonate intake.
- Osteomyelitis: Infection of the bone; not a direct risk in this scenario.
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
