what is the patient may be experiencing hyperkalemia, a tall peaked t wave often indicates this. 
300

With SIADH labs may show a decreased serum osmolarity but an increased urine osmolarity, this is because

what is water retention dilutes serum levels but despite adequate fluids, the pt is not peeing so the urine has more particles compared to fluids

300

A patient with hypercalcemia is ordered to do what

what is increase mobilization. This helps move Ca from blood back into the bone
