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?
Correct answer
D
Rationale
The correct answer is D: Muscle tremors. A calcium level of 8.0 mg/dL in a preschooler indicates hypocalcemia. Muscle tremors are a common manifestation of hypocalcemia due to the effect of low calcium levels on nerve and muscle function. Chvostek's sign is a facial muscle spasm elicited by tapping the facial nerve and is associated with hypocalcemia, so it should be positive, not negative. Polyuria is not typically associated with hypocalcemia. Dry, sticky mucous membranes are more indicative of dehydration rather than hypocalcemia. In summary, muscle tremors are the most likely finding due to the low calcium level in the preschooler.
