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.

Answer and Explanation

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","B","C"]

Explanation

Choice A reason:

The nurse should monitor blood glucose levels because dextrose 10% in water (D10W) is a hypertonic solution that contains glucose and can raise the blood sugar level of the patient. The nurse should check the blood glucose level before and after administering D10W to prevent hyperglycemia or hypoglycemia.

Choice B reason:

The nurse should check for signs of phlebitis at the IV site because D10W is acidic and can cause venous irritation. Phlebitis is inflammation of the vein that can result from chemical, mechanical or bacterial causes. Signs of phlebitis include pain, redness, swelling, warmth and tenderness at the IV site.

Choice C reason:

The nurse should assess for fluid overload because D10W is quickly metabolized, leaving behind water that can move into the interstitial space. Fluid overload can cause edema, dyspnea, crackles, distended neck veins, increased blood pressure and decreased urine output. The nurse should monitor the intake and output, vital signs, weight and breath sounds of the patient.

Choice D reason:

The nurse does not need to evaluate serum sodium levels because D10W does not contain sodium or affect the sodium balance of the patient. D10W is used to provide some nutrition with glucose, not to correct electrolyte imbalances.

Choice E reason:

The nurse does not need to observe for signs of hypoglycemia because D10W is unlikely to cause hypoglycemia unless there is a sudden interruption or discontinuation of the infusion. Hypoglycemia is a low blood sugar level that can cause shakiness, diaphoresis, confusion, weakness, hunger and headache. The nurse should monitor the blood glucose level and administer D10W at a steady rate to prevent hypoglycemia.

A. Decreased serum pH. B. Increased serum calcium. C. Decreased serum magnesium. D. Increased serum bicarbonate.

Correct Answer is C

Explanation

Choice A: Decreased serum pH. This is incorrect because hypokalemia usually causes increased serum pH, not decreased. This is because low potassium levels can lead to metabolic alkalosis, a condition where the blood is too alkaline due to loss of acid from the body. This can happen in cases of vomiting, diuretic use, or mineralocorticoid excess.

Choice B:

Increased serum calcium. This is incorrect because hypokalemia does not directly affect serum calcium levels. However, hypokalemia can cause hypomagnesemia, or low magnesium levels, which can in turn cause hypercalcemia, or high calcium levels. This is because magnesium is needed for the secretion of parathyroid hormone (PTH), which regulates calcium balance in the body. Low magnesium levels can lead to increased PTH secretion and increased calcium reabsorption from the bones and kidneys.

Choice C:

Decreased serum magnesium. This is correct because hypokalemia and hypomagnesemia often occur together, especially in cases of chronic diarrhea, malabsorption, alcoholism, or diuretic use. This is because potassium and magnesium are both lost in the urine or stool when these conditions are present. Hypomagnesemia can also cause hypokalemia by impairing the reabsorption of potassium in the kidneys and increasing the entry of potassium into the cells.

Choice D:

Increased serum bicarbonate. This is incorrect because hypokalemia usually causes decreased serum bicarbonate, not increased. This is because low potassium levels can lead to metabolic acidosis, a condition where the blood is too acidic due to accumulation of acid in the body. This can happen in cases of diabetic ketoacidosis, renal tubular acidosis, or chronic kidney disease.
