How much medication should be administered? Drug category: B. Parenteral Administration Medications for parenteral administration must be suspended in solution. The medication label indicates the amount of the drug contained in each mililiter of solution. For example, if a medication label reads 10 mg/mL, there are 10mg of medication for each 1 mL of liquid volume. Some medications, such as penicillin, insulin, and heparin, are ordered and meafured in units (c.g. 300,000 units/ mL ). This refers to their biologic activity in animal tests or the amount of the drug that is required to produce a particular response. Parenteral medication is available in several dispensing forms, including ampules, single-dose vials, and multiple-dose vials. After the proper drug dosage has been determined, the medication is drawn into a syringe from the dispensing unit. Most syringes are calibrated in milliliters (mL). Determining drug dosage for parenteral administration is calculated in a similar manner as that for oral liquid medication. The first problem illustrates the determination of drug dosage when the medication is ordered in a different unit of measurement from the dose on hand, requiring two calculation steps. Examples PROBLEM The provider orders 0.5 g of a medication IM. The medication label reads 250mg/2 mL How much medication should be administered? Step 1: Convert 0.5 g to milligrams. Step 2: Determine the amount of medication to administer to the patient: D+H×V=x 500mg+250mg×2 mL=x (500+250=2)×2 mL=x2×2 mL=xx=4 mLThe next problem illustrates the determination of drug dosage with a medication ordered in units. Notice that the dose ordered and the dose on hand are in the same unit of measurement; therefore, conversion of units of measurement is not necessary. Parenteral Administration: Practice Problems Determine the drug dosage to be administered for each of the following parenteral medication orders and document your answer. In the
