increase |
|
Parathyroid will be inhibited with ______ Ca or ______Mg |
high Ca, high Mg |
|
High Ca? ________ is released to lower it |
Calcetonin |
|
Low Ca? ________________ will be released to pull Ca from bone and increase Ca absorption in the kidney |
PTH |
|
Ca & ___________ are "brothers" |
Ph |
|
Ca and _________ are "sisters" |
MG |
|
PTH will: _____________ calcium absorption in the intestines |
increase |
|
PTH will: ____________ Ca excretion in the kidneys |
decrease |
|
PTH will ____________ Ca breakdown in the bone (PTH PULLS) |
increase |
|
High Ca stimulates _______________ from thyroid |
Calcitonin |
|
Calcitonin ___________ calcium in the bone. PTH __________calcium from the bone. |
Calcitonin keeps, PTH pulls |
|
Calcitonin causes kidneys to ______________ calcium |
excrete |
|
Serum Ph is _______________ to calcium |
inverse |
|
3 diagnostic studies for Parathyroid |
PTH, Serum Ca, Serum pH |
|
Hyperparathyroidism: describe |
Elevated PTH causes elevated blood calcium. |
|
Sx of Hyperparathyroidism |
are sx of high Ca: weakness, loss of appetite, constipation, increases need for sleep, emotional disorder, short attention span |
|
3 Major Signs of Hyperparathyroidism |
fractures, kidney stones, neuromuscular muscle weakness |
|
Ca levels in Hyperparathyroidism |
>10 |
|
Diagnostics for Hyperparathyroidism |
PTH, Serum calcium>10, elevated urine calcium, serum Cl, uric acid, Cr, amylase (pancreas), all phosphate (bone disease). Low Ph<3mg/dl, BMD, MRI/CT/US |
|
Diagnostics for Hyperparathyroidism: Ph |
<3mg/dl |
|
normal Ph |
2.4-4.4 |
|
normal magnesium |
1.5 to 2.5 |
|
Diagnostics for Hyperparathyroidism: expected serum calcium |
>10 |
|
Diagnostics for Hyperparathyroidism: 6 Elevated electrolytes |
elevated urine calcium, elevated serum Cl, uric acid, Cr, amylase, alk. phos. |
|
most effective surgical tx for hyperparathyroidism |
Parathyroidectomy |
|
what is a Parathyroidectomy |
most effective surgical tx for hyperparathyroidism, can be partial or total removal, done outpatient endoscopically |
|
5 criteria for Parathyroidectomy |
SERUM CA: >12mg/dl HYPERCALCIURIA: 400mg/day MARKEDLY REDUCED BMD NEUROMUSCULAR/NEPHROLITHIASIS AGE: under 50 years |
|
Post Parathyroidectomy watch for signs of: |
low calcium |
|
What are signs of low calcium |
Tetany, tingling, Trousseau's/Chvostek's sign |
|
4 Nursing management post parathyroidectomy |
KEEP IV CALCIUM BY THE BEDSIDE, I/O, Monitor Ca, Phosphate, Mg levels, Watch for signs of low Ca, Ambulate |
|
Conservative approach to hyperparathyroidism, non surgical DIET TX |
High fluid intake. Low Ca. Na 8-10g/d. Ph supplements |
|
Conservative approach to hyperparathyroidism, non surgical Monitoring |
Yearly serum PTH, calcium, phosphorus, alk phos. Test renal function. X-rays (assess for metabolic bone disease), measure urine calcium excretion. |
|
Goal of pharmacologic agents in tx hyperparathyroidism |
goal- lower Ca level |
|
Generic name for Fosamax |
Alendronate |
|
3 meds given for hyperparathyroidism |
1. Alendronate (Fosamax), 2. Phosphate, 3. Diuretics |
|
How does phosphate work in tx hyperparathyroidism |
stops vitamin D absorption at the intestine so calcium is not absorbed |
|
how do you give alendronate (Fosamax) |
take alendronate by mouth on an empty stomach in the morning at least 30 minutes before food, drink, or other medications. Swallow whole, take with a full glass of plain water. Do not lie down for 30 min after taking alendronate or prior to eating first food of the day. |
|
what is hypoparathyroidism |
inadequate circulating PTH causing hypocalcemia |
|
4 causes of hypoparathyroidism |
REMOVAL OF PARATHYROID. atrophy, antibodies, severe low MG w/ suppressed PTH. |
|
low calcium levels cause: |
chronic renal failure, vitamin D deficiency, hypomagnesemia, and atrophy of parathyroid gland |
|
nursing management tx goal for hypoparathyroidism |
tx tetany, keep normal Ca levels, prevent complications |
|
tx hypoparathyroidism w/ |
IV Ca |
|
S/e of IV Calcium |
low BP, arrhythmias, arrest, vein irritation (monitor digoxin levels) |
|
what does a rebreathing mask do for a patient with hypoparathyroidism |
increases CO2, makes them acidotic, lowers their calcium |
|
Diet for patient w/ hypoparathyroidism? |
high calcium diet: dark green vegetables, soybeans, tofu. |
|
how often should hypoparathyroidism patients have Ca drawn |
3-4 times per year |
|
2 vitamins to give to hypoparathyroidism patient |
1.5-3 grams PO calcium, Vitamin D (calcitriol) |
|
what is Calcitriol, what does it do |
vitamin D analog, helps to absorb calcium |
|
Diet for patient w/ hypoparathyroidism, what foods to avoid? |
oxalic acid: spinach, rhubarb (inhibit calcium absorption) |
|
what will patient look like with high calcium |
lethargic, memory loss, personality changes, anorexia (n/v), bone pain, polyuria, dehydration, kidney stones, stupor/coma. |
|
what will a patient look like with low calcium |
fatigue, depressed, numbness/tingling, hypereflexia, cramps, Chvostek/Trousseau's sign, Laryngeal spasm, Tetany/seizures. |
