NR 226 Exam 2 Practice NCLEX questions with answers and rationales 1. A nurse assesses a patient with hypoparathyroidism. The nurse notes a positive Chvostek’s sign and recognizes that it indicate... s with electrolyte imbalance? a. Hyperkalemia b. Hypermagnesemia c. Hypocalcemia d. Hyponatremia Explanation: Serum calcium levels are maintained through dietary intake and the parathyroid hormone. When more calcium is needed, parathyroid hormone is released to absorb calcium from bone, stimulate vitamin D activation, inhibit kidney excretion of calcium and stimulate kidney reabsorption of calcium. In hypoparathyroidism, the parathyroid gland does not produce adequate parathyroid hormone to maintain serum calcium levels, causing hypocalcemia. Hypocalcemia is an electrolyte imbalance in which total serum calcium is less than 8.5 mg/dL. Hypocalcemia can cause neuromuscular excitability, as seen in positive Chvostek sign. A positive Chvostek sign occurs when the nurse taps on the facial nerve at the angle of the jaw, resulting in contraction of the facial muscles. 2.
