| Question | Answer |
|---|---|
| converting between units | units you have * numbers of units that you want/units you have |
| 1:10 | 1g/10ml |
| 1:100 | 1g/100ml |
| 1:1,000 | 1g/1,000ml |
| celsius converions | c=(f-32)*(5/9) |
| farhenheit converion | f=c * (9/5)+ 32 |
| weight per volume (w/v) | g of drug/100ml of SOLUTION |
| weight per weight (w/w) | g of drug/100g of SOILD |
| volume per weight (v/w) | ml/100ml two solution together |
| order/stock | amount dispensed per dose |
| ratio/proportion | order=stock cross multipy then divide both side |
| pounds to kilograms | pounds/2.2kg |
| computation of dose by body weight (pounds or kilo) | (weight if child * adult dose)/1.7 |
| computation of dose by BSA | BSA in m2 * dose in mg/m2ie= useing a BSA of 0.4 m2, cal the dose for a pt prescribed 40mg/m2 kanamycin 40mg*0.4=16mg |
| young rule | age of child(yrs)/age of child + 12 *adult dose |
| clark rule | adult dose * weight of child/150 |
| enternal | med goes into digestive tact and is then absorbed into blood |
| parenteral | bypass the digestive tract and goes into the blood through a more direct route |
| subcutaneous injection (SC) | under skin |
| intramuscular injection (IM) | injected into the muscle for slow absorption |
| intraarterial injection (IA) | directly into artery |
| intrathecal injection (IT) | injected into the space surrounding the spinal cord |
| intracardiac injection (IC) | into the heart |
| intravenous injection (IV) | most common IV BOLUS-all at once IV DRIP- over long period of time |
| calculation of flow rate | volume of fluid to recive/time of infusion |
| drops per time | (volume / time)*drop factor |
| iv bags | dose of drug ordered/volume to add to iv=amount of drug in vial/amount of dilent add |
| calculation of the amount of drug infused per time or DROPS PER TIME | concentrstion * flow rate= dose/time(C*F=D/t) |
| calculating the concentration of drug (C) | amount of drug in g or mg/volume of fluid in IV bag=concentration of drug in solution |
| calculating the flow rate (F) | amount of fluid in the IV / time it takes the bag to empty=the flow rate |
