Correct Answer is ["937.5"]
Explanation
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.
