Question

A client experiences muscle cramps, numbness, tingling of the extremities, and twitching of the facial muscle and eyelid when the facial nerve is tapped. Which should the nurse consider this client is experiencing?

Answers

  1. Hypokalemia
    • Rationale:

      This answer is not correct because facial twitching, muscle cramps, numbness and tingling of the extremities are not associated with hypokalemia. The indicators of hypocalcemia are tingling and numbness of the lips, tongue, fingers and feet, muscle cramps, twitching of the facial muscles, and bone pain.

  2. Hypernatremia
    • Rationale:

      This answer is not correct because facial twitching, muscle cramps, numbness and tingling of the extremities are not associated with hypernatremia. The indicators of hypocalcemia are tingling and numbness of the lips, tongue, fingers and feet, muscle cramps, twitching of the facial muscles, and bone pain.

  3. Hypocalcemia
    • Rationale:

      This answer is correct because the client is experiencing symptoms indicative of low serum calcium levels; therefore the nurse considers that the client is experiencing hypocalcemia.

  4. Hypermagnesemia
    • Rationale:

      This answer is not correct because facial twitching, muscle cramps, numbness and tingling of the extremities are not associated with hypermagnesemia. The indicators of hypocalcemia are tingling and numbness of the lips, tongue, fingers and feet, muscle cramps, twitching of the facial muscles, and bone pain.

Learning Outcomes

Electrolytes play a vital role in maintaining homeostasis in the body. They help to regulate heart and neurological function, fluid balance, oxygen delivery, acid–base balance and much more. The indicators of hypocalcemia are tingling and numbness of the lips, tongue, fingers and feet, muscle cramps, twitching of the facial muscles, and bone pain. The Chvostek sign is considered positive when the facial muscle and eyelid twitch when the facial nerve is tapped.
