As part of the treatment for heart failure, the child takes the diuretic furosemide (Lasix). As part of teaching home care, the nurse encourages the family to give the child foods such as bananas, oranges, and leafy vegetables. These foods are recommended because they are high in which nutrient?
- A. Chlorides
- B. Potassium
- C. Sodium
- D. Vitamins

- B. Cessation of chest pain
- C. Reduce heart rate
- D. Decreased frequency of episodes of VT
