Electrolytes Question #67


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?


  1. Milk of Magnesia
    • Rationale:
  2. Docusate sodium
    • Rationale:
  3. Fiber-Con
    • Rationale:
  4. Bisacodyl
    • Rationale:



The correct answer is A. Clients with kidney problems are unable to tolerate excess magnesium. Overdosing on magnesium may result in toxicity. OTC products that contain magnesium should be avoided. Docusate sodium, Fiber-Con, and bisacodyl do not affect magnesium level.

NCLEX TIP: Using critical thinking is recommended when reading priority questions. Recognizing key words in the answer choices will allow you to know how to choose the correct answer for the question. Go through each answer choice and decide is it: Maslow’s hierarchy, safety-related, or following the nursing process (ADPIE). Never complete a nursing action that is outside the scope of practice.
