If a client’s potassium level increases from 4.3 to 7.8, what should the nurse's best action be?

• A. Administer Epinephrine
• B. Redraw the blood
• C. Notify the physician
• D. Assess the neurological status

Answer: (B)

When a client's potassium level rises significantly from a normal range (4.3 mEq/L) to a critical value (7.8 mEq/L), the priority is to ensure the accuracy of the result before taking further action. High potassium levels (hyperkalemia) can be life-threatening, leading to serious cardiac complications, so verifying the result through a redraw of the blood is essential. This method helps to confirm whether the initial reading was an error due to hemolysis, improper sample handling, or any other factors that could affect the potassium measurement. If the elevated level is confirmed, the nurse can then take the appropriate steps, which may include notifying the physician, assessing the patient, and implementing interventions. By opting for the redraw of the blood, the nurse ensures that the client receives accurate and timely care based on the true laboratory results.
