Medical Surgical Magnesium Mg+ #2

Question

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

Answers

  1. A client who has hyperthyroidism and a magnesium level of 1.6mEq/L.
    • Rationale:

      This answer is not correct because the client with hyperthyroidism has a low normal magnesium level (i.e., hypomagnesemia) not hypermagnesemia. Risk factors for the development of elevated serum levels of magnesium include kidney damage and antacid use.

  2. A client who has chronic alcoholism and a magnesium level of 1.3mEq/L.
    • Rationale:

      This answer is not correct because the client with chronic alcoholism has a magnesium level of 1.3 mEq/L which would indicate hypomagnesemia, not hypermagnesemia.

  3. A client who has renal failure, takes antacids, and has a magnesium level of 2.9 mEq/L.
    • Rationale:

      This answer is correct because this client has two risk factors for the development of hypermagnesemia, kidney failure and antacid use. This coupled with the serum magnesium level of 2.9 mEq/L indicates hypomagnesemia.

  4. A client who has congestive heart disease, takes a diuretic, and has a magnesium level of 2.3 mEq/L.
    • Rationale:

      This answer is not correct because the client with congestive heart failure has a magnesium level within normal limits. Risk factors for the development of elevated serum levels of magnesium include kidney damage and antacid use.

Overview

A normal serum magnesium level is 1.5-2.5 mEq/L. Risk factors for the development of elevated serum levels of magnesium include kidney damage and antacid use.

Explanation

Learning Outcomes

The medical term that indicates elevated serum magnesium levels in hypermagnesemia. Risk factors for the development of elevated serum levels of magnesium include kidney damage and antacid use. Therefore, a client who has renal failure, takes antacids, and has a magnesium level of 2.9 mEq/L most likely has hypermagnesemia.

Test Taking Tip

Consider each client’s medical diagnosis and the current serum magnesium level to answer this question correctly.
