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.

A. Place the patient on a cardiac monitor and check the patency of the IV B. Administer potassium intravenously in an IV push bolus C. Discontinue other medications that may affect potassium levels D. Avoid potassium rich foods in the diet

Correct Answer is A

Explanation

A. Place the patient on a cardiac monitor and check the patency of the IV: Hypokalemia (K+ = 2.5 mEq/L) can cause life-threatening cardiac dysrhythmias, so cardiac monitoring is essential. Additionally, potassium is highly irritating to veins, so IV patency must be confirmed to prevent extravasation and tissue damage.

B. Administer potassium intravenously in an IV push bolus- NEVER give potassium IV push as it can cause fatal cardiac arrest. Potassium must always be diluted and infused slowly.

C. Discontinue other medications that may affect potassium levels- Adjusting medications may be necessary, but not an immediate priority over cardiac monitoring.

D. Avoid potassium-rich foods in the diet - Incorrect because the client needs potassium replacement, not restriction.
