Furosemide (Lasix) is a loop diuretic used to treat fluid overload in conditions like heart failure. Its primary action is to promote diuresis (increased urine output), which helps reduce edema and fluid retention. An increase in urinary output is the most direct indicator of the medication’s effectiveness.
A: An increase in blood pressure is not the intended effect of furosemide in this context.
C: A decrease in heart rate is not directly related to the action of furosemide.
D: While the client may feel less anxious due to symptom relief, this is not a direct measure of the medication’s effectiveness.
