A nurse is providing discharge instructions to a client who has chronic heart failure and is prescribed furosemide, a loop diuretic. Which of the following dietary modifications should the nurse include in the teaching? (Select all that apply.)
Increase intake of foods high in potassium.
Decrease intake of foods high in sodium.
Increase intake of foods high in calcium.
Decrease intake of foods high in protein.
Increase intake of fluids as tolerated.
Correct Answer : A,B
Choice A reason:
Furosemide is a potassium-wasting diuretic that may reduce the potassium level in your blood. To counteract the loss of potassium, you should try to eat enough potassium-rich foods in your diet. Some examples of potassium-rich foods include bananas, orange juice, apricots, acorn squash, butternut squash, Hubbard squash, prunes, raisins, and bran products.
Choice B reason:
Furosemide is used to treat high blood pressure and edema by causing the kidneys to get rid of unneeded water and salt from the body into the urine. To enhance the effect of furosemide and prevent fluid retention, you should decrease intake of foods high in sodium. Some examples of sodium-rich foods include processed meats, canned soups, pickles, cheese, salted nuts, and snack foods.
Choice C reason:
Furosemide does not affect the calcium level in your blood significantly. Therefore, there is no need to increase intake of foods high in calcium when taking furosemide. However, you should still consume adequate amounts of calcium for your bone health and other functions. Some examples of calcium-rich foods include milk, yogurt, cheese, broccoli, kale, and fortified cereals.
Choice D reason:
Furosemide does not affect the protein level in your blood significantly. Therefore, there is no need to decrease intake of foods high in protein when taking furosemide. However, you should still consume moderate amounts of protein for your muscle health and other functions. Some examples of protein-rich foods include eggs, fish, poultry, meat, beans, nuts, and seeds.
Choice E reason:
Furosemide can cause dehydration and electrolyte imbalance by increasing urine output. Therefore, you should increase intake of fluids as tolerated to prevent these complications. You should drink enough water to keep your urine clear or pale yellow. You should also avoid alcohol and caffeine as they can worsen dehydration.

Correct Answer is A
Explanation
Choice A reason:
pH 7.50, PaCO2 40 mm Hg, HCO3- 30 mEq/L. This choice is correct because it shows a high pH, a normal PaCO2, and a high HCO3-, which are consistent with metabolic alkalosis. Metabolic alkalosis occurs when there is a loss of acid or a gain of base in the body fluids, such as from prolonged nasogastric suctioning. The kidneys try to compensate by excreting more bicarbonate, but this process is slow and incomplete.
Choice B reason:
pH 7.35, PaCO2 35 mm Hg, HCO3- 24 mEq/L. This choice is incorrect because it shows normal values for pH, PaCO2, and HCO3-, which indicate no acid-base imbalance. A client with metabolic alkalosis would have an elevated pH and bicarbonate level.
Choice C reason:
pH 7.25, PaCO2 50 mm Hg, HCO3- 26 mEq/L. This choice is incorrect because it shows a low pH, a high PaCO2, and a normal HCO3-, which are consistent with respiratory acidosis. Respiratory acidosis occurs when there is impaired gas exchange or hypoventilation, leading to an accumulation of carbon dioxide in the blood. The kidneys try to compensate by retaining more bicarbonate, but this process is slow and incomplete.
Choice D reason:
pH 7.30, PaCO2 30 mm Hg, HCO3- 18 mEq/L. This choice is incorrect because it shows a low pH, a low PaCO2, and a low HCO3-, which are consistent with metabolic acidosis. Metabolic acidosis occurs when there is a gain of acid or a loss of base in the body fluids, such as from diabetic ketoacidosis or diarrhea. The lungs try to compensate by increasing the rate and depth of breathing to expel more carbon dioxide, but this process is fast and limited.
Correct Answer is C
Explanation
Choice A reason:
Hypernatremia is not a likely complication of sodium chloride and potassium chloride IV fluids, because these fluids do not contain excessive amounts of sodium. Hypernatremia is more likely to occur with hypertonic saline solutions or excessive sodium intake.
Choice B reason:
Hypokalemia is not a likely complication of sodium chloride and potassium chloride IV fluids, because these fluids contain potassium, which can help prevent or correct hypokalemia. Hypokalemia is more likely to occur with diuretic therapy, vomiting, or diarrhea.
Choice C reason:
Hyperchloremic acidosis is a likely complication of sodium chloride and potassium chloride IV fluids, because these fluids can increase the serum chloride level and lower the serum bicarbonate level, resulting in a metabolic acidosis. Hyperchloremic acidosis can also worsen the client's existing metabolic alkalosis by impairing the renal excretion of hydrogen ions.
Choice D reason:
Hypochloremic alkalosis is not a likely complication of sodium chloride and potassium chloride IV fluids, because these fluids do not cause a loss of chloride or an increase in bicarbonate. Hypochloremic alkalosis is more likely to occur with vomiting, gastric suctioning, or diuretic therapy.
