    Question #1
    When interpreting serum chemistry from an electrolyte pathology report, which of the following is correct?

    A: Serum electrolytes are a measurement of intracellular tissue concentrationsB: Magnesium will only show as deficient in serum after the total body storage of this element is over 40% depleted

    Question #2
    Chloride and Bicarbonate share an inverse relationship and have a major role in balancing blood and cellular pH.

    A: TrueB: False

    Question #3
    Which of the following is correct?

    A: A high serum chloride and a low serum bicarbonate indicates acidosisB: A high serum bicarbonate and high serum chloride indicates acidosisC: Low serum potassium indicates alkalosisD: (a) and (c)E: None of the these

    Question #4
    24hr urinary sodium excretion is not the most accurate method to measure salt intake.

    A: TrueB: False

    Question #5
    Which of the following is correct?

    A: Administration of Na bicarbonate or Na citrate increases blood pressure, whereas Na phosphate does notB: Clients with cardiovascular disease or hypertension should be screened for Chloride and SodiumC: NaCl and non-chloride sodium salts activate the renin-angiotensin systemD: All of these

    Question #6
    Which of the following is correct?

    A: Metabolic acidosis results in a low bicarbonate level and high chloride levelB: Metabolic acidosis results in a high bicarbonate level and low chloride levelC: None of these

    Question #7

    A: TrueB: False

    Question #8
    The Anion Gap is a measure of the difference between cations (Na/k) and anions (Cl/HCO3):

    A: AG=(Sodium + Potassium) + (Chloride + Bicarbonate)B: AG=(Sodium + Potassium) - (Chloride + Bicarbonate)

    Question #9
    Approximately 85% of Phosphate is stored in bone.

    A: TrueB: False

    Question #10
