Study Notes
Medication Dosage Calculations
- Volume required for injection can be calculated by dividing the ordered dosage by the concentration of the stock solution.
- For instance, 500mg ordered with 250mg/ml stock requires 2ml (500mg / 250mg/ml).
- Similarly, for 600mg with 350mg/ml, the volume needed is approximately 1.71ml (600mg / 350mg/ml).
- An order of 750mg with stock of 200mg/ml requires 3.75ml (750mg / 200mg/ml).
- A 2g dose in a stock of 4g/0.4ml equals 0.2ml of medication (2g / (4g/0.4ml)).
- For 4500mg ordered and stock of 5g/0.3ml, the calculated volume is 0.27ml (4500mg / (5g/0.3ml)).
- A patient prescribed 3500mg with stock of 5g/2ml requires 1.4ml (3500mg / (5g/2ml)).
Infusion Rate Calculations
- To calculate DPM (drops per minute), first determine the total volume to be infused, then apply the dilution factor (DF).
- A flask of 1.5L (1500ml) of 0.9% saline over 8 hours with a DF of 20 results in 50 DPM (1500ml / 480min * 20).
- For a 1L flask of 4% dextrose over 6 hours at DF of 15, the rate is 62.5 DPM.
- An 850ml 0.9% saline over 12 hours with DF of 60 results in 71.25 DPM.
Weight-Based Medication Dosing
- Dosages based on weight utilize mg/kg calculations to establish required volumes and doses.
- A child weighing 13.5kg prescribed 0.8mg/kg/dose needs 1.08ml (10mg/2ml).
- For a 45kg patient with 3mg/kg/dose, the required volume is 7.5ml (2mg/0.5ml).
- A 16.5kg patient needing 0.4mg/kg/dose would receive 0.4ml (20mg/5ml).
- A 13kg child on 2.5mg/kg/day will get 32.5mg per day, administered per dose based on the number of doses.
- A 3.4kg child requiring 5mg/kg/day will receive 17mg per day split into 4 doses.
IV Bolus Administration
- For IV medication preparation, dosing calculations involve adjusting final volumes and flow rates.
- 1mg requires 10ml, administered over 3 minutes gives a rate of 3.33ml/min.
- 2mg mixed the same way is administered at 6.67ml/min over 3 minutes.
- For a 4mg dose over 5 minutes, the rate translates to 8ml/min.
General Medication Concentration Calculations
- Determining concentration involves dividing the total medication by total volume.
- A solution with 350mg in 100ml equates to 3.5mg/ml.
- A solution with 400mg in 300ml results in 1.33mg/ml.
- For 550mg in 200ml, concentration is 2.75mg/ml.
