• Question 231:

  Teaching about the need to avoid foods high in potassium is most important for which client?

  A. a client receiving diuretic therapy

  B. a client with an ileostomy

  C. a client with metabolic alkalosis

  D. a client with renal disease

  Correct Answer: D

  Clients with renal disease are predisposed to hyperkalemia and should avoid foods high in potassium. A client receiving diuretic therapy, a client with an ileostomy and a client with metabolic alkalosis are incorrect choices because clients receiving diuretics with ileostomy or with metabolic alkalosis are at risk for hypokalemia and should be encouraged to eat foods high in potassium.

• Question 233:

  When administering intravenous electrolyte solution, the nurse should take which of the following precautions?

  A. Infuse hypertonic solutions rapidly.

  B. Mix no more than 80 mEq of potassium per liter of fluid.

  C. Prevent infiltration of calcium, which causes tissue necrosis and sloughing.

  D. As appropriate, reevaluate the client's digitalis dosage. He might need an increased dosage because IV calcium diminishes digitalis's action.

  Correct Answer: C

  Preventing tissue infiltration is important to avoid tissue necrosis. To infuse hypertonic solutions rapidly is incorrect because hypertonic solutions should be infused cautiously and checked with the RN if there is a concern. To mix no more than 80 mEq of potassium per liter of fluid is incorrect because potassium, mixed in the pharmacy per physician order, is mixed at a concentration no higher than 60 mEq/L.
