## Question

Place the steps for safe intravenous potassium phosphate replacement in order.

Monitor the infusion site, cardiac status when indicated, and the client for acute adverse findings.

Verify whether the supplied product is a concentrate or ready-to-use bag and follow its preparation instructions.

Review current phosphorus, potassium, calcium, magnesium, and renal function.

Program the prescribed rate and use the access route required by the final concentration and osmolarity.

Recheck the ordered electrolytes and clinical response after the infusion.

## Explanation

Assessment precedes product-specific preparation, followed by correct route and rate, active monitoring, and post-infusion reassessment.

## In-depth explanation

Quick answer
Use assess → identify product → program route/rate → monitor → reassess.

Why this is correct
Potassium phosphate products differ: concentrates require dilution, while some bags are ready to use. Renal function and potassium determine safety, and phosphorus, calcium, and magnesium must be trended.

Easy analogy or mental picture
Read the map and the vehicle label before selecting the road, then watch the trip and check the destination.

Memory hook
Labs first, formulation second, pump third, trend throughout.

NCLEX decision rule
Never assume all potassium phosphate products share the same preparation instructions.

Why the other choices are wrong
Starting before renal and electrolyte review can expose a contraindication; skipping follow-up misses hyperkalemia, hyperphosphatemia, hypocalcemia, or hypomagnesemia.References

## Clinical scenario

Electrolyte infusion sequence
Confirm renal function, all relevant electrolytes, exact product, access, concentration, pump rate, and post-dose monitoring.
