<prompt> Please answer with one of the option in the bracket. Write reasoning in between . Write answer in between .Q:A 30-year-old woman is brought to the urgent care clinic by her husband. She complains of numbness around her lips and a tingling sensation in her hands and feet. She underwent near-total thyroidectomy for an enlarged thyroid gland a month ago. Vital signs include: blood pressure is 13070 mm Hg, pulse is 72min, respiratory rate is 16min, and temperature is 37.0C 98.6F. A surgical incision scar is present in the anterior aspect of the neck. The attending physician inflates the blood pressure cuff above 150 mm Hg and observes the patient a couple of minutes while measuring her blood pressure. The patient develops sudden stiffness and tingling in her hand. Blood test results are as follows:Hemoglobin Hb 10.2 gdLWhite blood cell count 7000mm3Platelet count 160,000mm3Calcium, serum Ca2 6.0 mgdLAlbumin 4 gdLAlanine aminotransferase ALT, serum 15 ULAspartate aminotransferase AST, serum 8 ULSerum creatinine 0.5 mgdLUrea 27 mgdLSodium 137 mEqLPotassium 4.5 mEqLMagnesium 2.5 mEqLUrinalysis shows no white or red blood cells and leukocyte esterase is negative. Which of the following is the next best step in the management of this patient?? A: CT scan abdomen with pancreatic protocol, B: Thyroid function tests, C: Serum vitamin D level, D: 24-hour urinary calcium, E: Serum parathyroid hormone PTH level,  <response>: This is a patient who recently underwent thyroidectomy surgery and is now presenting with numbness around the lips and tingling sensations in the hands and feet. The description of the blood pressure cuff test inducing stiffness and tingling in her hand points towards hypocalcemia as the likely cause of her symptoms. Thyroidectomy can damage the parathyroid glands leading to hypoparathyroidism and hypocalcemia. The blood test results confirm low calcium levels. The next step would be to check parathyroid hormone PTH levels to confirm hypoparathyroidism as the cause of hypocalcemia. The other tests listed are not relevant in this clinical scenario.E: Serum parathyroid hormone PTH level
