Phosphorus (reg, hypo, & hyper) Flashcards
what is the range of phosphorus
2.4 - 4.5
what is phosphorus regulated by
parathyroid & calcitriol
what are the main functions of phosphorus (3)
helps reg calcium (inverse relationship w/ ca & mg)
cellular metabolism & energy production through ATP
essential for bones & teeth
what causes hypophospatemia (2)
insufficient intake
increased excretion
what cause insufficient intake of phosphorus
malnutrition
starvation
Refeeding syndrome
what is re-feeding syndrome
fatal shift of fluids & electrolytes that may occur in malnourished pts
what causes increased phosphorus excretion (4)
hyperparathyroidism - calcium rise, phosphorus drops
malignancy
diuretics & diarrhea
use of mg-based or aluminum-based antacids
will a pt’s bp & hr be increased or decreased on hypophosphatemia
decreased
what bowel sounds will be in hypophos
hypoactive
what will form in the kidneys of a pt w/ hyposphos
kidney stones
will the pt be oreiented or have altered LOC in hypophos
altered LOC
will pt have increased or decreased DTR in hypophos
decreased
how will the muscles be impacted in a pt with hypophos
severe muscle weakeness
what will have pain in the body and be at risk for more fractures in hypophos
bones
what are the interventions for hypophos (2)
replace phos IV or PO
Fracture precautiosn
what should we admin oral phos along with
vitamin d
how quick should we admin phos if it’s severely low
slowly
what cause hyperphos (5)
increased intake
overuse of laxative & enemas w/ phos
decreased excretion due to renal insufficiency
hyperparathyroidism
hypocalcemia
what will be the neuromusc symps in a pt w/ hyperphos (6)
irritable skeletal muscles - twitching, cramps, tetany, seizures, parasthesias
painful spasms in calf/foot
pos. trousseau’s & chvostek’s signs
hyperactive DTRs
osteoporosis - body trying to get more calcium
what GI symps will be present in pt w/ hyperphos
hyperactive bowels
diarrhea
what are the hyperphos interventions
same as hypocalcium
