Diuretic use: Low potassium in a patient with CHF is most commonly due to diuretic use. Treatment options under a doctor's supervision include the use of ace inhibitors or ace blockers which are useful in CHF and can raise potassium, or increasing the dose of the spirinolactone, triampterine or potassium. Magnesium should be checked as well.

Hard to say.: The diuretics are designed to spare potassium, but they are not strong diuretics. Another diuretic, like furosemide, can cause potassium loss. It can be a GI cause, like diarrhea, or hormonal, like insulin, or renal. There may not be enough potassium in the diet, and/or dose might be too low. More info. May be needed, and you might have to see your doctor for more work-up/med. Adjustment.

Lasix (furosemide)?: This is clearly a abnormal. Potassium losses like this have to be distinguished between GI losses from diarrhea or renal losses. A trans tubular potassium gradient can help.
