The nurse is assessing a client who exhibits positive Trousseau's and Chvostek's signs.
What laboratory value would validate these clinical findings? A serum:
potassium 4.2 mEq/L
phosphate 3.0 mg/dL
magnesium 1.8 mEq/L
calcium 6.9 mg/dL
calcium 6.9 mg/dL
The Correct Answer is D
Choice A rationale: A potassium level of 4.2 mEq/L is within the normal range and would not validate Trousseau's and Chvostek's signs.
Choice B rationale: A phosphate level of 3.0 mg/dL is within the normal range and would not validate Trousseau's and Chvostek's signs.
Choice C rationale: A magnesium level of 1.8 mEq/L is within the normal range and would not validate Trousseau's and Chvostek's signs.
Choice D rationale: A calcium level of 6.9 mg/dL is below the normal range and could validate Trousseau's and Chvostek's signs.
