A nurse is assessing a preschooler who has a calcium level of 8.0 mg/dL.
Which of the following findings should the nurse expect?
Negative Chvostek's sign.
Muscle tremors.
Dry, sticky mucous membranes.
Polyuria.
The Correct Answer is B
A calcium level of 8.0 mg/dL is below the normal range for adults, which is 8.8 to 10.4 mg/dL.
This condition is known as hypocalcemia and can cause muscle spasms and aches.
Choice A is incorrect because a positive Chvostek’s sign, not a negative one, is a clinical sign of hypocalcemia.
Choice C is incorrect because dry, sticky mucous membranes are not a symptom of hypocalcemia.
Choice D is incorrect because polyuria (frequent urination) is a symptom of hypercalcemia (high calcium levels), not hypocalcemia.
