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.
Sodium bicarbonate.
Dextrose 10%.
Sodium polystyrene sulfonate (Kayexalate).
Insulin.
Correct Answer : A,C,D
A, C, and D.
Choice A rationale:
The administration of sodium bicarbonate helps to correct acidosis, which can occur in chronic renal failure due to the accumulation of metabolic waste products in the absence of effective kidney function.
Choice C rationale:
Sodium polystyrene sulfonate (Kayexalate) is used to treat hyperkalemia, which is common in chronic renal failure due to impaired potassium excretion by the kidneys.
Choice D rationale:
Insulin can be prescribed to treat hyperkalemia by promoting the uptake of potassium into cells, thereby reducing the serum potassium level. Choice B and E rationale: Dextrose 10% and furosemide (Lasix) are not appropriate treatments for hyperkalemia. Dextrose 10% is a sugar solution and does not impact potassium levels, while furosemide is a loop diuretic that primarily affects sodium and water excretion, not potassium.

Correct Answer is ["C","D","E"]
Explanation
The correct answer is choiceC. Monitor the injection site for redness,D. Use an infusion controller for the IV, andE. Monitor fluid intake and output.
Choice A rationale:
Adding the ordered dose to the IV hanging is incorrect because potassium chloride should never be added to an already hanging IV solution due to the risk of uneven distribution and potential overdose.
Choice B rationale:
Administering the dose IV push over 3 minutes is incorrect because potassium chloride should never be given by direct IV injection.It must always be diluted and administered slowly to prevent cardiac complications.
Choice C rationale:
Monitoring the injection site for redness is correct because potassium chloride can cause irritation and phlebitis at the injection site.
Choice D rationale:
Using an infusion controller for the IV is correct because it ensures the potassium chloride is administered at a controlled rate, reducing the risk of rapid infusion and potential cardiac issues.
Choice E rationale:
Monitoring fluid intake and output is correct because it helps assess the patient’s overall fluid balance and detect any signs of fluid overload or deficit, which is crucial when administering potassium.
Correct Answer is D
Explanation
Choice A rationale:
Hypokalemia is not a direct adverse effect of dextrose 10% in water infusion. This solution does not contain potassium, and unless the patient already has low potassium levels or other contributing factors, it would not cause hypokalemia.
Choice B rationale:
Hypercalcemia is unrelated to dextrose 10% in water infusion. The solution does not contain calcium, and it would not lead to an increase in serum calcium levels.
Choice C rationale:
Hypovolemia, or low blood volume, is not typically associated with dextrose 10% in water infusion. However, if administered rapidly in large amounts, it could potentially cause fluid overload leading to hypervolemia.
Choice D rationale:
Hyperglycemia is a possible adverse effect of dextrose 10% in water infusion. The solution contains a high concentration of glucose, which can raise blood sugar levels if the body cannot adequately utilize or regulate the glucose. Regular monitoring of blood glucose levels is essential during such an infusion, especially in patients with diabetes or impaired glucose tolerance.
