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 B
Explanation
A. Discard the client's last void at the end of the collection time period. The last void must be included for complete data.
B. Refrigerate the urine during the collection time period: Refrigerating the urine prevents bacterial growth and chemical breakdown, ensuring accurate lab results. Some tests may require urine to be kept on ice instead.
C. Save the first void at the start of the collection time period. The first void is discarded because it may contain residual metabolites from the previous period.
D. Include toilet paper with the collected urine. Toilet paper can contaminate the sample and alter test results.
Correct Answer is C
Explanation
A. Stable blood pressure, normal urine output, and flat neck veins. BP and urine output are not stable in hypovolemia.
B. Nausea, vomiting, diarrhea, and normal blood pressure. These can contribute to hypovolemia, but BP is not normal in severe cases.
C. Tachycardia, decreased blood pressure, and decreased urine output. Hypovolemia (low blood volume) causes compensatory tachycardia to maintain perfusion. BP drops due to decreased circulatory volume. Urine output decreases (<30 mL/hr) due to reduced renal perfusion.
D. Tachycardia, increased blood pressure, and poor skin turgor. BP is decreased, not increased in hypovolemia.
