How much elemental Iron is in ferrous fumarate, ferrous sulfate, and
ferrous gluconate? - CORRECT ANSWERS fumarate: 108 mg
sulfate: 65 mg of 325mg (20%)

How is absolute neutrophil count calculated? - CORRECT ANSWERS ANC=
WBC x [(%segs + %bands)/100]
What is the formula to determine a patient's total energy expenditure? -
CORRECT ANSWERS TEE= BEE x activity factor X stress factor
What is the equation to find pH of a weak acid? - CORRECT ANSWERS pH =
pKa + log(salt/acid)
What is the equation to find pH of a weak base? - CORRECT ANSWERS pH
= (pKw - pKb) + log(base/salt)
what can we tell about ionization of acids from the pH and the pKa? -
CORRECT ANSWERS pH > pKa more acid is ionized
pH = pKa ionized and unionized are equal
pH < pKa more acid is unionized
An ionized drug is more soluble but cannot easily cross lipid membranes
and vice versa
How are the ABG measurements written out on the exam? - CORRECT
ANSWERS pH/pCO2/pO2/HCO3/O2

What are the normal values for pH, HCO3, and pCO2? - CORRECT ANSWERS
pH = 7.35-7.45
HCO3 = 38-42
pCO2 = 22-28
When adding calcium and phosphate to TPN what should be considered? -
CORRECT ANSWERS -Use calcium gluconate over calcium chloride because
it is less reactive and a lower rate of precipitation.
-Add phosphate first then add calcium at the end of the prep
-when added together don't exceed 45 mEq/L
BMI - CORRECT ANSWERS weight in kg/height in meter^2
How many kcals are in 10%, 20%, and 30% intravenous fat emulsions?
How much fat is needed for TPN? - CORRECT ANSWERS 10% = 1.1
kcal/mL
20% = 2 kcal/mL
30% = 3 kcal/mL
Fat for TPN = 9 kcal/gram
How many kcals do amino acids and dextrose provide in TPN? - CORRECT
ANSWERS Amino acids 4 kcal/gram
dextrose 3.4 kcal/gram
what is the pKa? - CORRECT ANSWERS The pKa is the pH at which half the
drug is 50% ionized. This is half the neutralization or equivalence point.

The neutralization or equivalence point is at a much higher pH and occurs
when the acid has been neutralized.
what is the correct calcium equation? - CORRECT ANSWERS Corrected Ca
= [(4.0-albumin) x 0.8] + serum calcium
What is the equation for absolute bioavailability? - CORRECT ANSWERS F=
100 x (AUC extravascular/AUC intravascular) x (Dose intravascular/Dose
extravascular)
What is the equation to find the volume of distribution? - CORRECT
ANSWERS Vd = amount of drug given/concentration of drug in plasma
What is the equation for clearance? - CORRECT ANSWERS Cl = rate of
elimination/concentration
Cl = F x Dose/AUC
Cl = Dose/AUC (if bioavailability is 1)
What is the equation for corrected phenytoin? - CORRECT ANSWERS CP=
measured serum phenytoin/(0.2*albumin)+0.1
