Final answer:
Patients taking Lasix are instructed to include potassium in their diets to prevent potassium deficiency.
Step-by-step explanation:
The statement is true. Patients taking Lasix, also known as furosemide, a diuretic medication, may experience potassium deficiency as a side effect. Potassium is an essential mineral that plays a critical role in various bodily functions, including maintaining proper heart rhythm and muscle contractions. Therefore, to prevent potassium imbalance, patients are often instructed to include potassium-rich foods in their diets or take potassium supplements under medical supervision.
