Final answer:
The assessment finding that requires action by the nurse is potassium of 2.9 mEq/L due to the potential potassium depletion caused by the diuretic drugs.
Step-by-step explanation:
The assessment finding that requires action by the nurse is potassium of 2.9 mEq/L.
Triamterene-hydrochlorothiazide (Dyazide) and furosemide (Lasix) are both diuretics that can cause potassium depletion, known as hypokalemia, as a side effect. Potassium levels below 3.5 mEq/L are considered low and require intervention.
Potassium is essential for normal heart function, and low levels can lead to cardiac arrhythmias. Therefore, a potassium level of 2.9 mEq/L indicates a potential electrolyte imbalance that needs to be addressed by the nurse.
