A client with severe burns has crystalloid fluid replacement ordered using the Parkland formula. The initial volume of fluid to be administered in the first 24 hours is 30,000 mL. The initial rate of administration is 1875 mL/hr. After the first 8 hours, what rate should the nurse infuse the IV fluids?
The Correct Answer is ["937.5"]
Calculate the fluid volume to be administered in the remaining 16 hours:
Total fluid volume - Fluid administered in the first 8 hours = Remaining fluid volume
30,000 mL - (1875 mL/hr * 8 hr) = 15,000 mL
Calculate the infusion rate for the remaining 16 hours:
Remaining fluid volume / Remaining time = Infusion rate
15,000 mL / 16 hr = 937.5 mL/hr
Therefore, the nurse should infuse the IV fluids at a rate of 937.5 mL/hr after the first 8 hours.

Correct Answer is B
Explanation
A. Assessing oral temperature is not a priority immediately after an electrical burn, as the focus should be on monitoring for cardiac issues and other life-threatening conditions.
B. Electrical burns can cause cardiac arrhythmias, including dysrhythmias like ventricular fibrillation, which can be life-threatening. The nurse should place the client on a cardiac monitor immediately to detect any abnormal rhythms and respond accordingly.
C. While checking potassium levels is important for assessing potential complications such as kidney damage or arrhythmias, cardiac monitoring should take precedence.
D. Assessing for pain at contact points is important, but it is secondary to ensuring cardiac stability in an electrical burn victim.
Correct Answer is B
Explanation
A. Lantus insulin does not directly affect potassium levels in the same way that digoxin does.
B. A potassium level of 3.0 mEq/L is low, and digoxin toxicity can occur when potassium levels are low, leading to an increased risk of arrhythmias. This requires immediate attention to avoid serious complications.
C. Metoprolol is a beta-blocker that does not directly cause hypokalemia and is less of an immediate concern.
D. Ibuprofen is a nonsteroidal anti-inflammatory drug (NSAID) that could affect kidney function but does not directly impact potassium levels as significantly as digoxin.
