Electrolytes Question #33


The nurse is reviewing data received during handoff communication. Which client should the nurse expect to have hypermagnesemia?


  1. A client who has chronic alcoholism and a magnesium level of 1.3mEq/L
    • Rationale:
  2. A client who has hyperthyroidism and a magnesium level of 1.6mEq/L
    • Rationale:
  3. A client who has renal failure, takes antacids, and has a magnesium level of 2.9 mEq/L
    • Rationale:
  4. A client who has congestive heart disease, takes a diuretic, and has a magnesium level of 2.3 mEq/L
    • Rationale:



The correct answer is C. Risk factors for the development of hypermagnesemia include kidney damage and antacid use. A normal serum magnesium level is 1.5-2.5 mEq/L. The client with renal failure, antacid use, and a magnesium level of 2.9 mEq/L most likely has hypermagnesemia. The client with chronic alcoholism has a magnesium level of 1.3 mEq/L which would indicate hypomagnesemia. The client with hyperthyroidism has a low normal magnesium level. The client with congestive heart failure has a magnesium level within normal limits.

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.
