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 A
Explanation
A. The best response is to educate the client about the cause of Prinzmetal angina. It occurs due to spasm in the coronary arteries, which is different from the plaque buildup seen in traditional coronary artery disease. This response addresses the client's concern in an accurate and reassuring manner.
B. While healthy eating is important, Prinzmetal angina is not typically caused by cholesterol or plaque buildup. This response could increase the client's anxiety.
C. While acknowledging the client's emotions is important, this response does not address the underlying concern or provide an accurate explanation of Prinzmetal angina.
D. Offering reassurance without providing accurate information about the condition does not help the client understand the cause of their symptoms and could leave them confused or anxious.
