You receive an order to replace a potassium infusion rate for a patient with hypokalemia. What nursing assessment and actions are appropriate?

• A. Confirm order, check serum K+, monitor for signs of hyperkalemia, monitor telemetry, and ensure IV access; never push potassium; administer per protocol.
• B. Immediately speed up the rate.
• C. Ignore telemetry.
• D. Discontinue the infusion.

Answer: (A)

When replacing potassium IV for hypokalemia, the important idea is to ensure safe, rate-controlled replacement while watching the heart and the IV site. Potassium must be given only as ordered, with the current potassium level known, because both too little and too much potassium can cause serious heart rhythm problems. This means confirming the order and checking the serum potassium before starting, then continuously watching the patient’s condition as the infusion runs.

The best approach includes several key safety steps. Confirming the order and reviewing the current potassium level helps you know how much replacement is appropriate. Monitoring for signs of hyperkalemia—such as changes in rhythm, muscle weakness, or ECG abnormalities—and keeping telemetry on screen allows early detection of trouble. Ensuring IV access and using a controlled administration method (typically with a pump and according to protocol) reduces the risk of delivering potassium too quickly. Never pushing potassium directly into the vein is essential because IV push can cause rapid, dangerous spikes in potassium and precipitate life-threatening arrhythmias. Following the facility’s protocol for dosing and rate ensures that you’re applying tested, safe practices rather than improvising.

Additional context that supports safe practice includes considering renal function and urine output, since impaired excretion can raise potassium risk, and inspecting the IV site for irritation or infiltration. By combining lab data, cardiac monitoring, appropriate infusion technique, and adherence to protocol, you protect the patient during the correction of a potentially dangerous electrolyte imbalance.

Why the other options don’t fit: speeding up the rate can overwhelm the heart with potassium too quickly; ignoring telemetry risks missing early signs of dangerous shifts in rhythm; and discontinuing the infusion would leave hypokalemia untreated, risking ongoing arrhythmias and weakness.
