  • essential for nerve & muscle function, acid/base balance, formation of rbcs, atp, bones & teeth

    What are functions of phosphorus?

  • respiratory acidosis

    This can cause a shift of phosphorus out of the cells.

  • respiratory alkalosis

    This can cause a shift of phosphorus into the cells.

  • increases GI absorption, movement of phosphorus out of the bone, promotes renal excretion

    How does PTH influence phosphorus?

  • True

    Serum phosphate is under tight physiological control. T/F?

  • hypophosphatemia

    <2.5 mg/dL phosphate = ?

  • critically ill

    Hypophosphatemia is most common in ________.

  • insulin, glucose, carbs

    Which compounds can cause Phosphorus to move from blood and into cells due to metabolic demands?

  • tissue repair, decreased: magnesium, potassium, hyperparathyroidism, thiazide

    What are some causes of hypophosphatemia?

  • phosphorus binding antacids, vomiting, diarrhea, malabsorption, vitamin d deficiency

    What can cause decreased absorption of phosphorus in hypophosphatemia?

  • aluminum, calcium, magnesium

    What are our phosphorus binding antacids?

  • DKA treatment, severe burns, alcohol, alcohol withdrawal

    Combination causes of hypophosphatemia?

  • d

    Which medication can cause hypophosphatemia?

    a) propanolol

    b) penicillin g

    c) cefalosporin

    d) laxative

  • multifactorial

    The causes of hypophosphatemia in critically ill patients are considered _______.

  • decreased grip strength, seizure, chest pain, respiratory muscle weakness, bleeding, hemolysis, difficulty speaking, risk of infection

    Signs & symptoms of acute hypophosphatemia?

  • cyanosis, joint stiffness, osteomalacia

    Signs & symptoms of chronic hypophosphatemia?

  • NaPhos, KPhos

    Treatment of severe hypophosphatemia?

  • neutraphos, iv phosphorus

    Treatment of mild hypophosphatemia?

  • tumor lysis syndrome

    -hyperphosphatemia is considered secondary to this condition and should be treated promptly.

  • tumor lysis syndrome, cell turnover, acute celluar shift

    Endogenous Hyperphosphatemia?

  • DKA, hyperglycemia, lactic acidosis

    What conditions can cause acute cellular shift?

  • release of phosphate

    What is cellturnover?

  • exogenous

    What is considered more rare; endogenous or exogenous hyperphosphatemia?

  • c

    _______ can lead to acute phosphate nephropathy.

    a) phosphate binders

    b) KPhos

    c) Laxatives

    d) NaPhos

  • a,d

    Which of the following is a potential cause of hyperphosphatemia?

    a) volume depletion

    b) calcium supplements

    c) smoking

    d) fertilizer poisoning

  • respiratory/metabolic acidosis, dka, leukemia, lymphoma, trauma, chemo, rhabdomyolysis

    What conditions can cause hyperphosphatemia?

  • hypocalcemia

    Hyperphosphatemia & _______ have associated symptoms.

  • soft tissue calcification, oliguria, irregular hr

    Symptoms of metastatic diseased hyperphosphatemia?

  • c

    Which treatment medication is a phosphate binder used to treat hyperphosphatemia?

    a) aluminum

    b) calcium

    c) renvela

    d) vitamin d

  • b

    Which antacid is preferred in renal failure caused by hyperphosphatemia?

    a) aluminum

    b) calcium

    c) magnesium

    d) potassium

  • Dialysis

    _________ may be necessary in severe acute hyperphosphatemia, with symptompatic hypocalcemia
