KEY HLTH 3219 - Pharm Math Review Sheet for Child Health Nurses KEY ( rev F15) Show your calculations for each question. Calculate to 2 decimal places, then round to 1 decimal place. 1. Review Math Calculations and Decimals 1. 4.32 + 2.01 + 0.04 = _6.37 _= 6.4 2. 732 – 255 = 477 3. 10.35 – 1.87 = 8.48 = 8.5 4. 396 x 287 = 113652 5. 23.12 x .78 = 18.03 = 18 6. 2125 ¸ 25= 85 7. 5.01 ¸ 4.2 = 1.19 = 1.2 2. Perform these conversions: (Weight: 1g = 1000mg; 1mg =1000mcg; 1 kg = 1000g) (Volume: 1 L = 1000 mL; 1 mL = 0.001 L; 1 mL = 1 cc) Length: 1 m =100 cm = 1000 mm; 1 cm = 10 mm) a) 6.25mg = 6250 mcg b) 1.85g = 1850 _ mg c) 4000g = 4 Kg d) 40 lbs = _18.18 =18.2 Kg 1 Kg = 2.2 lb = 40/2.2 = 18.18 Kg=18.2Kg e) 14.3 lbs = _6500 ___g = __6.5 _Kg f) 1 fl oz = _30 ___ mL g) 3 tsp = _15 ___ mL 5ml/tsp; 3 X 5 = 15 mL h) 30 in = __75 ____cm 1 in=2.5cm; 30 X 2.5 = 75 cm 3. Solve for the value of x in the following : a) 50mg per 2mL = 75mg per x mL x = __3 mL ___ b) 1.25mg per 1 tab = 3.75mg per x tab x =__3 tabs ___ c) 300mg per 5ml = 250mg per x ml x = _4.17_mL = 4.2 mL 1
Medication Orders and Calculations: 1. Doctor orders: Coumadin 7.5 mg. p.o. O. D. (once daily) Identify which preparations you would give ________and how much _________. 1 tab of 5mg; 1 tab of 2.5mg __and Total = 7.5 mg with the 2 tabs . 2. Doctor orders Dexamethasone 6 mg. O. D. Identify which preparations you would use ___________and the amounts ________________ 1 tab of 5mg + 2 tabs of the 0.5mg or 1 tab of 5mg + 0.5 tab of the 2mg tab _ 3. Doctor orders Heparin 700 i.u. s.c. b.i.d. Which preparation(s) would you select?_ 1000u/mL ______ How much would you give? 0.7mL _Recommended for children that s.c. injection be 0.5mL – this is just slightly above that, but accuracy is key. 4. Doctor orders atropine sulfate 0.3 mg. I.M. 1 hr. preop. How much would you give? 5. Doctor orders furosemide 30 mg. in 500 cc D5W. How much would you insert into the IVbag? 6. Doctor orders carbenicillin disodium 750 mg I.M. Q6HUsing the 17 mL of diluent, how much would you give? So with 17 ml of diluent, concentration is 1 G in 4 mL (1000 mg = 1 G ) or 1000mg/4 mL=750mg/x. 2 Coumadin 2.5 mg Warfarin Sodium Tabs Coumadin 5 mg Warfarin Sodium Tabs Dexamethasone 0.5mg/tab Dexamethasone 2 mg/tab Dexamethasone 5 mg/tab Heparin Sodium Injection 5,000 Units/mL for IV or SC Heparin Sodium Injection 1000 Units/mL for IV or SC Add 17 mL diluent to give dosage of 1 G in 4 mL
7. Doctor orders: Potassium Chloride 10 mEq. to 500 cc D5W.How much would you add to the 500cc D5W? 10mEq/x=2mEq/ml = 5 mL
