    • Malignancy

    • Drug overdose

    Correct Answer
    A. Kidney injury
  • 11. 

    Your CHF patient has abnormal sodium test results. Would you expect this to be hyponatremia or hypernatremia?

    • Hyponatremia

    • Hypernatremia

    These are part of the Basic Metabolic Panel.

    • Sodium, potassium, protein

    • Sodium, creatinine, calcium

    • Sodium, creatinine, bilirubin

    • Chloride, BUN, albumin

    Correct Answer
    A. Sodium, creatinine, calcium
    Explanation
    Basic:
    sodium, potassium, chloride, carbon dioxide, BUN, creatinine, glucose, calcium
    Complete:
    all basic + AST, ALT, alkaline phosphatase, total bilirubin, total protein, albumin

    Rate this question:

  • 15. 

    BUN:Creatine ration is usually ___.

    • 1:1

    • 20:1

    • 10:1

    • 1:10

    Correct Answer
    A. 10:1
    Explanation
    If greater than 20:1 consider pre-renal causes of azotemia (high BUN) such as dehydration or GI bleed.

    Rate this question:

  • 16. 

    If you order a serum calcium (instead of a free calcium), what else do you need to order along with it?

    • Vitamin D level

    • Potassium

    • Albumin level

    • Magnesium

    Correct Answer
    A. Albumin level
    Explanation
    Half of calcium is bound to albumin. If albumin is low, then calcium level will also be low.
    (You can run an equation to get a corrected calcium using a "normal" albumin of 4)

    These can be causes of hyperkalemia (check all that apply):

    • ACE inhibitors

    • CCBs

    • Bumetanide

    • Spironolactone

    Correct Answer(s)
    A. ACE inhibitors
    A. Spironolactone
    Explanation
    Bumetanide is a loop diuretic - would be more likely to cause LOSS of potassium, hypokalemia

    Rate this question:

  • 22. 

    All of these can be causes of LOW blood glucose except:

    • Thiazides

    • Propranolol

    • Malignancy

    • Starvation

    Correct Answer
    A. Thiazides
    Explanation
    thiazides can cause hyperglycemia

    Rate this question:

    If your patient is hypercalcemic, what other electrolyte should you check in order to help determine the cause of the hypercalcemia?

    • Chloride

    • Potassium

    • Sodium

    • Magnesium

    Correct Answer
    A. Chloride
    Explanation
    If chloride is high, then the cause of the hypercalcemia is primary hyperparathyroidism.
    If chloride is normal, then the cause of the hypercalcemia is malignancy.
