The nurse is providing education to a client that has a new prescription for furosemide (Lasix). Furosemide is a diuretic used to decrease high blood pressure and manage the client's heart failure. The nurse would incorporate which statement during the teaching session?

Choice A rationale Furosemide is a potent loop diuretic that causes increased excretion of potassium (K+) in the renal tubules, which can lead to hypokalemia (serum K+ less than 3.5 mEq/L). Increasing the intake of potassium-rich foods, such as spinach and kale, is an essential dietary instruction to help mitigate the risk of this potentially dangerous electrolyte imbalance associated with the medication. Choice B rationale Furosemide is prescribed, in part, to manage heart failure and hypertension, conditions that require sodium restriction to reduce fluid retention and circulating blood volume. Encouraging increased sodium intake through foods like luncheon meat and chips would directly counteract the therapeutic goals of the diuretic and exacerbate the client's underlying medical conditions. Choice C rationale Diuretics, particularly thiazides and loop diuretics like furosemide, are not typically associated with causing hypoglycemia (low blood sugar). In fact, they can sometimes cause or worsen hyperglycemia (high blood sugar) by impairing insulin release and glucose utilization, making increased intake of sweets an inappropriate and potentially harmful recommendation. Choice D rationale While maintaining adequate hydration is important, increasing daily water intake to 3500 mL, especially in a client with heart failure and fluid volume overload, is contraindicated and could worsen the fluid overload. Diuretics are given to remove excess fluid, and fluid intake should be monitored and often restricted to prevent exacerbation of symptoms and further cardiac strain.
