Potassium supplementation is LEAST likely to be required in a patient using:
- A) Ethacrynic acid (Edecrin)
- B) Chlorthalidone (Hygroton)
- C) Furosemide (Lasix)
- D) Acetazolamide (Diamox)
- E) Triamterene (Dyrenium)***
The answer is (E) Triamterene (Dyrenium).
Triamterene is a potassium-sparing diuretic, which means that it helps to remove excess fluid from the body without causing a significant loss of potassium. This makes it less likely that patients taking triamterene will need to supplement with potassium.
The other diuretics listed in the answer choices are all potassium-wasting diuretics, which means that they can cause the body to lose potassium in the urine. This can lead to hypokalemia, a condition in which the blood potassium level is too low. Patients taking potassium-wasting diuretics may need to supplement with potassium to prevent hypokalemia.
Here is a brief overview of the diuretics listed in the answer choices:
- Ethacrynic acid (Edecrin):
A loop diuretic that is used to treat edema and high blood pressure.
- Chlorthalidone (Hygroton):
A thiazide diuretic that is used to treat high blood pressure and edema.
- Furosemide (Lasix):
A loop diuretic that is used to treat edema, high blood pressure, and heart failure.
- Acetazolamide (Diamox):
A carbonic anhydrase inhibitor that is used to treat glaucoma, mountain sickness, and edema.
- Triamterene (Dyrenium):
A potassium-sparing diuretic that is used to treat edema and high blood pressure.
