Which of the following should be monitored while a patient is on Hydrochlorothiazide and Triamterene?

Monitoring potassium levels while a patient is on Hydrochlorothiazide and Triamterene is important due to the pharmacological properties of these medications. Hydrochlorothiazide is a thiazide diuretic that can cause potassium depletion, leading to hypokalemia. On the other hand, Triamterene is a potassium-sparing diuretic, which helps to maintain potassium levels in the body.

When these two medications are used in combination, it is crucial to closely monitor potassium levels to avoid potentially dangerous fluctuations. The combination can help mitigate some of the potassium-wasting effects of Hydrochlorothiazide, but it is still essential to regularly check electrolyte levels to ensure the patient does not develop hyperkalemia or remain hypokalemic.

Monitoring of blood glucose levels, blood urea nitrogen levels, and heart rate are important considerations in overall patient care but are not as critical as potassium monitoring specifically in the context of these two diuretics.
