A patient weighing 176 lbs. is recovering from mild dehydration. The patient is awake, alert, and can safely take oral fluids. How many mL of fluid should the nurse instruct the patient to consume every day?

What will be an ideal response?

Question 2

A patient with chronic renal failure has an occluded arteriovenous fistula, and routine hemodialysis is delayed. However, the patient's serum potassium level is 6.0 mEq/L. What should the nurse expect to be prescribed for this patient?

Select all that apply.
1. insulin
2. dextrose 10
3. furosemide (Lasix)
4. sodium bicarbonate
5. sodium polystyrene sulfonate (Kayexalate)

Answer to Question 1

Correct Answer: 2400 mL

Adults require approximately 30 mL per kilogram of body weight per day for body maintenance. First convert the patient's weight in lbs. to kg by dividing 176/2.2 = 80 kg. Next multiply the amount of fluid per kg by the kg or 30 mL/kg 80 kg = 2400 mL. The nurse should instruct the patient to ingest 2400 mL of fluid per day.

Answer to Question 2

Correct Answer: 1, 2, 4

Insulin, hypertonic dextrose (10 to 50), and possibly sodium bicarbonate are used in the emergency treatment of moderate to severe hyperkalemia (serum potassium > 6.0 to 6.5 mEq/L). Insulin promotes the movement of potassium into the cell, and glucose prevents hypoglycemia. Sodium bicarbonate elevates the serum pH; potassium is moved into the cell in exchange for hydrogen ion. Sodium polystyrene sulfonate (Kayexalate) is used to treat moderate or severe hyperkalemia. Furosemide (Lasix) is a potassium-wasting diuretic used to enhance renal excretion of potassium. The patient is in chronic renal failure and most likely does not have a urine output.
