ratio strength= 100/% strength
How do we get the percent strength from the ratio strength? - CORRECT ANSWERS %
strength= 100/ratio strength
How do we convert PPM to percent strength? - CORRECT ANSWERS -PPM to %
strength, move decimal left 4 places
-% strength to PPM, move decimal place right 4 places
specific gravity - CORRECT ANSWERS SG= grams of substance/mL
mEq - CORRECT ANSWERS mEq= mg x valence/MW

gluconate 35 mg
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

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
