Renal Disorders & Supplementa Flashcards
Why is calcitriol? And who takes it and why?
- it is an active form of vitamin D
Taken in hypocalcemia
And for pt with CKD on hemodialysis
IF their kidneys are unable to activate calcium on their own to create vitamin D activated
If the kidneys are still able to activate it on their own, pt will only be taking calcium supplements and not calcitriol
Which electrolytes does calcitriol (vitamin D3 activated) promote their absorption?
Promotes the absorption of calcium and phosphate
What are the contraindications to calcitriol?
KDA
Hypercalcemia
What are possible AE of calcitriol?
- nausea & vomiting
- fatigue
- weakness
- dysrhythmias
What are some possible interactions that can occur with calcitriol?
Can cause hypercalcemia with foods high in calcium so
Best to avoid or not eat to much of:
- tofu
- milk
- yogourt
- cheese
- leafy greens
- beans
- trout
What is calcium used for in kidney disease/injury?
Kidney disease/injury causes hypocalcemia so calcium supplements will be given to prevent body from going to get calcium in the bones of the body as it can lead to osteoporosis
So used for :
- hypocalcemia
- kidney failure
- vitamin d deficiency
- intestinal absorption of vitamin D and gastric secretion
What are some contraindications to calcium supplements ?
- hypercalcemia
- V fib
- KDA
What are some possible AE with calcium supplements?
- hypercalcemia
- anorexia, n&v, constipation
- heart irregularities
What are some possible drug interactions with calcium supplements?
- calcium may decrease absorption of thyroid replacement drugs (levothyroxine) so take 2 hrs before taking calcium
- if hypercalcemia occurs and pt is on digoxin = risk for serious cardiac dysthymias
How should calcium supplements be taken ?
- take oral dose 1 to 3 hrs AFTER meals
- don’t take at same time as levothyroxine (take 2 hrs after levothyroxine)
- monitor for hypercalcemia (anorexia, n&v, constipatiin)
The nurse is administering prescribed calcium to a pt IV. Which of the following AE should the nurse monitor for if calcium is given too fast?
A) ototoxicity
B) kidney damage
C) tetany
D) cardiac dysrhytmias
D
Sometimes cardiac monitor is needed
What AE may occur from calcium salt infusion?
A ) ototoxicity
B) metabolic acidosis
C) nephrotoxicity
D) resp arrest
B
Which dietary information is important for the pt taking calcium supplements?
A) oral calcium supplements should be taken before meals
B) calcium products bind with tetracyclines making the antibiotic inactive
C) foods high in calcium include whole grain, cereals, eggs yolks, and liver
D) foods high in oxalate and zinc, such as spinach and légumes increase the absorption of oral calcium supplementation
B
