NAPLEX 2024: Calculations1 cup - ANS 1 cup = 8 oz
1 gallon - ANS 1 gallon = 4 quarts = 3785 mL
1 quart - ANS 1 quart = 2 pints = 946 mL
1 tsp = ? mL - ANS 5 mL
1 tbsp = ? mL - ANS 15 mL
1 oz = ? mL - ANS 30 mL (29.57 mL actual)
1 pint - ANS 1 pint = 16 oz = 473 mL
1 grain = ____ mg - ANS 1 grain = 65 mg
Conversion from aminophylline to theophylline - ANS aminophylline x 0.8 = theophyllin dose
BMI and its range - ANS (kg)/(m^2)
Normal = 18.5 - 24.9
Overweight >25
Obese >/= 30
IBW - ANS male = 50 kg + (2.3 x each inch over 5ft)
term-9
female = 45.5 kg + (2.3 x each inch over 5ft)
CrCl - ANS [(140-age)(wt. in kg)/(72 x SCr)] x 0.85 if female
Specific Gravity - ANS Volume(mL) x SG = weight(g)
Also: SG = gram / mL
Body Surface Area - ANS sqrt[(Ht(cm) x Wt(kg))/3600] = BSA(m^2)
Half-life - ANS T1/2 = 0.693/k
Dextrose = ____ kcal/g for PN - ANS Dextrose = *3.4* kcal/g
Amino Acids (protein) = ____ kcal/g for PN - ANS Amino Acids (protein) = *4* kcal/g
, Lipids = ____ kcal/g for *EN* - ANS Lipids = *9* kcal/g
(note: Lipid emulsions contain glycerol so they are not straight 9 kcal/g as if they were pure fat
and the calories are calculated per mL of the formulation used)
10% lipid emulsion = ____ kcal/mL for PN - ANS 10% lipid emulsion = *1.1* kcal/mL
20% lipid emulsion = ____ kcal/mL - ANS 20% lipid emulsion = *2* kcal/mL
Determining Fluid Needs - ANS weight >20kg = 1500mL + (20 mL)(WT in kg-20 kg)
Basal Energy Expenditure (BEE) estimation - ANS BEE can be estimated = 15 to 25 kcal/kg
Total Energy Expenditure (TEE) - ANS TEE = BEE x activity factor x stress factor
Activity factor is 1.2 if confined to bed, 1.3 if ambulatory.
Amino Acids (proteins) should not be counted as part of the TEE for pts that are critically ill (TEE
calories should be made up of carbs+lipids)
Corrected Ca - ANS Corrected Ca = (serum Ca) + [ (4 - albumin) x 0.8 ]
1 g Nitrogen = ____ g protein - ANS 1 g Nitrogen = *6.25* g protein
mEq - ANS (mg x valence)/MW
or
mmols x valence
ANC - ANS
Calcium carbonate = ?% elemental Ca; calcium citrate = ?% elemental Ca - ANS Carbonate
40% elemental calcium.
Calcium citrate contains 21% elemental calcium
Corrected Phenytoin - ANS Use this formula if hypoalbumin (< 3.5g/dL)
If given free levels on exam → don't need to do correction
*Dose increment if needed adjustment: 30 - 50 mg at a time*
Ratio Strength shortcut - ANS Ratio Strength to Percentage Strength
% strength = 100 / ratio strength
Percentage Strength to Ratio Strength
ratio strength = 100 / percentage strength
