following thyroidectomy young pt on maintanous iv dextrose and saline she develeped tetany and found serum calcium 2.20 mmol/L a blood PH of 7.48 and paco2 of 24 mmhg .most likeli diagnosis is.

1- metabolic alkalosis from dextrose and saline infusion
2-respiratory alkalosis-----------------
3-acute deficency of calcitonin
4-postoprative hypoparathyroidism
5-thyroid crisis

Acute hypocapnia causes a reduction of serum levels of potassium and phosphate secondary to increased cellular uptake of these ions. A reduction in free serum calcium also occurs. Calcium reduction is secondary to increased binding of Ca++ to serum albumin. Many of the symptoms present in persons with respiratory alkalosis are related to the hypocalcemia. Hyponatremia and hypochloremia may also be present.
