Rationale behind decreasing calcium intake prior to parathyroidectomy?

Nurses Medications

Is this done to avoid a sudden decrease in Calcium after the procedure?

Huh?

This does not make sense. The pt is at risk of a calcium crisis post op so I don't really understand this.

Is this a homework question?

What do you think? Why is a parathyroidectomy indicated...for what condition? What does that condition cause? Is the CA restricted because of the surgery or the disease?

I am studying for the NCLEX using Kaplan and this was one of the questions. It said that calcium needs to be reduced prior to the procedure, but did not really explain why. The only rationale that I can think of is that they decrease calcium intake so that after the parathyroid is removed (which controls the release of calcium), the body doesn't go into shock because of the change in calcium level? I'm not sure..

Unless you have an overactive parathyroid and need to decrease calcium because of that...

exactly!

Most parathyroidectomies are performed for primary hyperparathyroidism. The most common cause of primary hyperparathyroidism is parathyroid adenoma, which accounts for 80-90% of cases. The diagnosis of primary hyperparathyroidism requires, minimally, an increased serum total calcium level with an increased intact PTH level—or, at least, an inappropriately high normal PTH level. Serum calcium levels can fluctuate somewhat, but patients with primary hyperparathyroidism should have a documented increase in serum total or ionized calcium sometime during the course of the condition....which would make the decreasing of calcium important. But careful monitoring of CA levels is imperative post op to prevent complications.
