What will happen to parathyroid hormone with decreased levels of vitamin D?
What is the corrected calcium equation?
What does vitamin D do to calcium?
INCREASE
Measured calcium + (0.8*(4-serum albumin))
raises absorption of calcium.

Yes.
Ergocalciferol, cholecalciferol, anything that ends in rol.
Should calcium carbonate be taken with food? Calcium citrate? What is the max dose to take due to absorption?
Calcium repletion pearls?

Yes. Doesn’t matter for citrate. 500 mg per dose.
Use calcium gluconate to reduce risk for extravasation. IV push in emergency ONLY.
Hyperparathyroid, malignancy, medications(thiazide diuretics, lithium, abuse of calcium containing antacids).

Phosphorus repletion pearls?
What causes hyperphosphatemia?
Who to watch for with phosphate containing laxatives?
When doing IV if <4 mEq use potassium phosphate. If higher than 4 use sodium phosphate. Max infusion rate is 7.5 mMol/hr to prevent symptomatic hypocalcemia.
