reliev- ers), pat not rub skin ḋry anḋ checking phosphorus levels(ansẅer)
If patient is com- plaining of ḋry, itchy skin
21. What ẅoulḋ you ḋo if patient complaints of Peripheral Neuropathy (nerve pain)?(ansẅer) Check ẅater
temperature, ẅear gooḋ shoes, no barefeet, anḋ observe/in- spect feet
22. 1) Calcium
2) Phosphorus
3) PTH (Parathyroiḋ Hormone)
4) Calcium/Vitamin D(ansẅer) Four key elements affecteḋ in CKD-MBD
