For a client with acute kidney injury and hyperkalemia, which of the following is a priority nursing action?

• A. Begin potassium-sparing medications
• B. Place the client on a cardiac monitor
• C. Encourage high-potassium foods
• D. Limit intravenous fluids

Answer: (B)

The priority nursing action for a client with acute kidney injury and hyperkalemia is to place the client on a cardiac monitor. This is crucial because high levels of potassium in the blood can lead to serious cardiac complications, including arrhythmias or even cardiac arrest. The heart is highly sensitive to potassium levels; therefore, monitoring the cardiac rhythm allows for early detection of any abnormalities that could occur due to hyperkalemia. In the context of acute kidney injury, where the kidneys may not effectively excrete potassium, monitoring becomes even more critical. Continuous cardiac monitoring provides real-time assessment of the client's cardiac status and ensures timely intervention if dysrhythmias develop. This action prioritizes patient safety and addresses the immediate risks associated with elevated potassium levels. The other options, while relevant to the management of kidney injury and electrolyte imbalances, do not address the immediate life-threatening risks associated with hyperkalemia in the same way that cardiac monitoring does.
