BMI formula
BMI = weight (kg) / height (m2)
Underweight BMI
< 18.5
Normal BMI
18.5 - 24.9
Overweight BMI
25 - 29.9
Obese BMI
30 or higher
When to use IBW
With hydrophilic drugs that don’t get distributed much into fat (e.g., AG’s, theophylline); using ABW for a drug that stays in the blood can cause an overdose
IBW formula (men)
50 kg + 2.3 kg per inch over 5 feet
IBW formula (women)
45.5 kg + 2.3 kg per inch over 5 feet
Normal range SCr
0.6 - 1.2 mg/dL
S/S of dehydration
BUN:SCr >20 Decreased urine output Tachycardia / tachypnea Dry mouth, dry mucous membranes Dry skin w/tenting
Cockcroft-Gault equation
CrCl (mL/min) = [ (140 - age) / (72 x SCr) ] x wt (kg)
x 0.85 (females only)
CrCl levels
>90 = normal 60-90 = mild insufficiency 30-59 = moderate insufficiency 15-29 = severe insufficiency <15 = renal failure or dialysis
Specific gravity
g/mL (same as density)
When is BSA used for dosing?
Chemo & pediatrics
BSA formula
BSA (m2) = sq rt of: (cm x kg) / 3600
Formula for changing the concentration or quantity
Q1 x C1 = Q2 x C2
Half-life formula

Daily fluid needs
(when weight >20 kg):
1500 mL + (20)(kg - 20)
Protein requirements for non-stressed outpatient
0.8-1 g/kg/day
Protein requirements for inpatient or malnourished
1.2-2 g/kg/day
Basal energy expenditure
(BEE): aka basal metabolic rate (BMR); amount of energy used in the resting state, exclusive of eating & activity; non-protein calories only; uses the Harris-Benedict equation
Total energy expenditure
(TEE): aka total daily expenditure (TDE); BEE x activity factor (energy used for activity) x stress factor (excess metabolic demands from stress); non-protein calories only
How much nitrogen does the patient receive from protein?
1 g nitrogen per 6.25 g protein
Normal range for K+
3.5 - 5.0 mEq/L
Normal range for calcium
8.5 - 10.5 mg/dL
Formula for corrected calcium
Ca(corr) = (Ca) + [ (4 - albumin) (0.8) ]
Things to know about phosphorus + calcium in a TPN
- Calcium gluconate is less reactive w/phosphate than calcium chloride, so has less risk of precipitation
- Add phosphate first, then other components, then calcium toward the end
- Do not exceed a total (Ca + PO4) of 45 mEq/L
- Keep refrigerated so less Ca & PO4 can dissociate & form a precipitate with each other
Statute vs. regulation
Statutes are created by the state legislature; regulations are developed & enacted by state agencies empowered by the state legislature & the governor; Board of Pharmacy is one of these state agencies
Mandatory vs. permissive language in a law
Mandatory = "must" or "shall" Permissive = "may" or "can" (allows judgment by the pharmacist)
The CA BoP is under the jurisdiction of which department of the state gov’t?
Dept. of Consumer Affairs
Number of members on the CA BoP?
How many appointed by the governor?
How many are pharmacists?
13 members, 11 appointed by the governor; 7 of the governor’s appointments are RPh, 5 of whom are actively practicing
How long is the term for a member of the CA BoP?
How often do they meet?
4 year terms, max 2 terms; meet at least every 4 months
Who can prescribe without a protocol?
MD, DO, DDM, DPM, DVM
MVI-13
Fat soluble ADEK + water-soluble thiamine, riboflavin, niacin, pantothenic acid, pyridoxine, C, folic acid, B12, & biotin (MVI-12 does not have K)
Trace elements given in TPN
Zinc, copper, chromium, manganese (and sometimes selenium); iron not usually given
Trace elements to be withheld w/severe liver disease
Manganese & copper
Trace elements to be withheld w/severe renal disease
Chromium, molybdenum, selenium
How much insulin is usually added to TPN?
50% or less of normal requirement + sliding scale; minimum is 10 units, and gets increased 10 units at a time
Separation between enteral nutrition & drugs with interactions
Hold feedings 1 hour before or 2 hrs after drug is administered
Drug interactions w/enteral nutrition
- Warfarin - drug gets bound by EN, lowering the INR
- FQ’s & TCN’s - chelate metals
- Phenytoin suspension - drug gets bound to EN, causing sub-therapeutic levels
Osmolarity definition
Total number of solutes per liter of solution (mOsmol/L); can be ionic (NaCl disassociated into the solutes Na+ and Cl-) or non-ionic that do not dissociate (glucose, urea)
Osmolarity of body fluids
Called “tonicity”; isotonic (same osmolarity as blood) is ~300 mOsmol/L)
Dissociation of dextrose
1 dissociation particle
Dissociation of mannitol
1 dissociation particle
Dissociation of KCl
2 dissociation particles
Dissociation of NaCl
2 dissociation particles
Dissociation of sodium acetate
2 dissociation particles
Dissociation of calcium chloride
3 dissociation particles
Dissociation of sodium citrate
4 dissociation particles
Osmolarity formula
mOsmol/L = [ (wt in g/L) / (MW in g/mole) ] x # of dissociation particles x 1000
