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. Tachycardia is an early compensatory sign of hypovolemic shock due to decreased circulating volume.
B. Increased temperature suggests infection or inflammation, not hypovolemic shock.
C. A slight decrease in urine output from 120 to 115 mL/hr is not significant; oliguria would be a more concerning sign.
D. A decrease in respiratory rate is not typical of hypovolemic shock, which usually causes tachypnea.
Correct Answer is C
Explanation
A. Urine output should increase with adequate fluid replacement, not decrease.
B. Weight may increase with fluid resuscitation due to fluid accumulation; a decrease is not a reliable sign of adequate resuscitation in the acute phase.
C. Heart rate. In burn patients, tachycardia is often a compensatory response to hypovolemia. A decrease in heart rate indicates improving circulatory volume and perfusion, suggesting effective fluid resuscitation.
D. Blood pressure should increase or stabilize with adequate fluids; a decrease suggests inadequate perfusion or ongoing hypovolemia.
