Study Notes
Dosage Calculations
- Fluorouracil dosage calculation: 12mg/kg/day, not to exceed 800mg/day; for a 132lb patient, the dose would be 720mg
- Cefaclor dosage calculation: 20mg/kg/day in 3 divided doses; for a 31lb patient, the dose would be 280mg, divided into 3 doses of 93mg each
- Mephenytoin dosage calculation: 200mg/m² PO in 3 divided doses; for a 42-inch tall, 44lb patient, the dose would be 160mg, divided into 3 doses of 53mg each
Pharmacology and Medication Orders
- Types of medication orders: stat, single, and standing orders
- Essential parts of a medication order: full name of client, date and time order is written, name of drug to be administered, dosage of drug, frequency of administration, route of administration, and signature of person writing the order
- Communicating medication orders: written chart, phone, or verbally; copied to Kardex or MAR, or on computer printout
Systems of Measurement and Conversion
- Gram (weight): 1kg = 2.2lbs
- Liter (volume): 1L = 1000mL
- Meter (length): 1m = 100cm = 1000mm
- Conversions: lb → kg, kg → lb, mL → L, L → mL
Body Surface Area (BSA) and Body Weight
- BSA calculation: most accurate way for infants, children, older adults, and patients on antineoplastic agents or with low body weight
- Determining drug dose per body weight: convert lbs to kg, determine drug dose per BW by multiplying drug dose x # of square meters
