client who suffered burn injuries to their face and entire left arm is to receive lactated ringers. The client weighs 73 kg. How much fluid will be infused for the first 8 hours? (Round to the nearest whole number).
The Correct Answer is ["1971"]
Face: 4.5%
Left arm: 9%
Total TBSA = 4.5 + 9 = 13.5%
Fluid needed in 24 hours = 4 mL × 73 kg × 13.5 = 3942 mL (rounded)
Half of this is given in the first 8 hours: 3942 ÷ 2 = 1971 mL

Correct Answer is A
Explanation
A. In the compensatory stage of shock, blood pressure is usually maintained within normal limits due to vasoconstriction and increased cardiac output.
B. A heart rate of 160/min is excessively high and more typical of the progressive stage of shock.
C. Hypokalemia is not a typical finding specific to the compensatory stage of shock.
D. Mottled skin usually occurs in the later stages of shock due to poor perfusion, not during compensation.
Correct Answer is A
Explanation
A. The pH is low (normal 7.35–7.45), indicating acidemia. The HCO₃⁻ is decreased (normal 22–26 mEq/L), indicating a metabolic cause. The PaCO₂ is normal (35–45 mm Hg), showing no respiratory compensation or cause. These findings are consistent with metabolic acidosis.
B. Respiratory alkalosis would show an elevated pH (>7.45) and decreased PaCO₂ (<35 mm Hg).
C. Respiratory acidosis would show a low pH (<7.35) and elevated PaCO₂ (>45 mm Hg).
D. Metabolic alkalosis would show a high pH (>7.45) and elevated HCO₃⁻ (>26 mEq/L).
