The charge nurse has stated a client has hyperkalemia and needs cardiac monitoring. The nurse noted which of following lab values?
Sodium 148
Potassium 3.1
Sodium 130
Potassium 5.7
The Correct Answer is D
A. Sodium 148: This represents mild hypernatremia, but sodium levels are not the primary concern for cardiac monitoring.
B. Potassium 3.1: This is hypokalemia (low potassium), not hyperkalemia.
C. Sodium 130: This represents hyponatremia, which can cause neurological symptoms, not hyperkalemia.
D. Potassium 5.7: Hyperkalemia is defined as K⁺ >5.0 mEq/L. Levels above 5.5 can cause dangerous cardiac dysrhythmias, requiring ECG monitoring.

- Rounded to the nearest tenth = 7.9
Correct Answer is D
Explanation
A. Administering medications at different times: timing does not affect renal function monitoring.
B. Comparing the client’s armband with the MAR: this is a safety check, not a precaution for renal function.
C. Monitoring for a decrease in BUN and creatinine: a decrease does not indicate renal impairment.
D. Closely monitoring the client's BUN and creatinine for an increase from baseline: Renal function declines with age, increasing the risk of drug accumulation and toxicity. An increase in BUN (normal: 7-20 mg/dL) and creatinine (normal: 0.6-1.3 mg/dL) indicates worsening kidney function and necessitates medication adjustments.
