Medical Surgical Magnesium Mg+ #5

Question

The nurse is preparing discharge teaching for a client with chronic renal failure. Which over-the-counter product will the nurse teach the client to avoid?

Answers

  1. Milk of magnesia
    • Rationale:

      This answer is correct because clients who are diagnosed with kidney failure will be unable to filter the blood and remove excess fluid, electrolytes, and waste products from the body. Because magnesium is an electrolyte that can cause toxicity if not filtered and removed from the body by the kidneys, those who are diagnosed with kidney failure should avoid products rich in magnesium, including milk of magnesia.

  2. Docusate sodium
    • Rationale:

      This answer is not correct because docusate sodium does not contain magnesium; therefore, does not increase the risk for hypermagnesemia which can lead to toxicity. Because magnesium is an electrolyte that can cause toxicity if not filtered and removed from the body by the kidneys, those who are diagnosed with kidney failure should avoid products rich in magnesium, including milk of magnesia.

  3. Fiber-Con
    • Rationale:

      This answer is not correct because Fiber-Con does not contain magnesium; therefore, does not increase the risk for hypermagnesemia which can lead to toxicity. Because magnesium is an electrolyte that can cause toxicity if not filtered and removed from the body by the kidneys, those who are diagnosed with kidney failure should avoid products rich in magnesium, including milk of magnesia.

  4. Bisacodyl
    • Rationale:

      This answer is not correct because bisacodyl does not contain magnesium; therefore, does not increase the risk for hypermagnesemia which can lead to toxicity. Because magnesium is an electrolyte that can cause toxicity if not filtered and removed from the body by the kidneys, those who are diagnosed with kidney failure should avoid products rich in magnesium, including milk of magnesia.

Overview

Chronic kidney (i.e., renal) disease or chronic kidney failure describes the gradual loss of kidney function. The kidneys filter waste and remove excess fluid from the blood. As kidneys fail, waste builds up.

Explanation

Learning Outcomes

The kidneys filter waste and remove excess fluid from the blood. As kidneys fail, waste builds up. Clinical manifestations develop slowly and often are not specific to the disease. Some clients, however, have no symptoms and are diagnosed by laboratory testing.Clients with kidney problems are unable to tolerate excess magnesium. Overdosing on magnesium may result in toxicity; therefore, over-the-counter (OTC) products that contain magnesium (e.g., milk of magnesia) should be avoided.

Test Taking Tip

Consider the ingredients for each medication and the diagnosis of chronic renal failure to answer this question correctly.
