The nurse assessing a client hospitalized with a diagnosis of hypoparathyroidism notes positive Trousseau's and Chvostek's signs. The nurse determines that these findings most indicate which electrolyte imbalance?
Hypernatremia
Hypermagnesemia
Hypocalcemia
Hypokalemia
The Correct Answer is C
Rationale:
A. Hypernatremia, an elevated sodium level, does not cause Trousseau's or Chvostek's signs.
B. Hypermagnesemia, an elevated magnesium level, is not associated with positive Trousseau's and Chvostek's signs.
C. Hypocalcemia, a low calcium level, is commonly associated with positive Trousseau's and Chvostek's signs. Trousseau's sign is a carpopedal spasm induced by inflating a blood pressure cuff, while Chvostek's sign is facial twitching in response to tapping over the facial nerve. Both are indicative of neuromuscular irritability due to low calcium levels.
D. Hypokalemia, a low potassium level, does not cause these specific signs and is associated with different clinical manifestations.
