A client is prescribed 1 g potassium phosphate IV to be infused continuously over 6 hr. Available is 1 g potassium phosphate in 250 mL dextrose 5% water (D,W). The nurse should set the IV pump to run at how many mL/hr? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
The IV pump should be set to run at 41 mL/hr.
Calculation:
1 g potassium phosphate = 250 mL solution
1 g potassium phosphate IV over 6 hr = 250 mL solution over 6 hr
250 mL / 6 hr ≈ 41.67 mL/hr
Round to nearest whole number = 42 mL/hr
Therefore, the IV pump should be set at 42 mL/hr.
