Question

I am struggling with easy problem. Can you pls check my work ? The patient is to receive 500 mL of D5W over 6 hours . What is the drip rate per minute if the tubing provides 12 gtts per mL? Gtt/min 12gtt/ml x 500/360 min =6000/360=118 gtt/min A patient who weighs 74 pounds has an order for Advil (ibuprofen) 3.5 mg/kg every 6 hours. How many mg will you give in a single dose? 3,5MG /KG X33.6KG =118 MG 74 PONDS =33.6 KG A 15 pound child has an order for an antibiotic for 55 mg/kg/every 6 hours. The antibiotic comes as 1 g/25 mL. What is the amount of a single dose? 55MG/KG/DOSE X1kg/2.2lbsx 15 lbsx25ml/1gr x1gram /1000mg 9, 4 ml The order is to give 60 mg of Garamycin (gentamicin) IM every 8hr. The vial is labeled 80 mg/ 2 mL. How many mL will you give? 60mg x2ml/80 mg =160/80 2 ml I did not put hours because I want to know ml only ? Give Pronestyl (procainamide HCl) 200 mg. The drug is available as 0.5 g/ mL. How many mL will you give? 200mgxml/05mg =200/0.5 The recommended dose for an antibiotic is 80mg/kg/day. If the patient weighs 38 kg how many mg/day should the patient receive? 80x38 =3040 mg /day

Answer 1

Question : The patient is to receive 500 mL of D5W over 6 hours . What is the drip rate per minute if the tubing provides 12 gtts per mL?

Answer : 17 gtt/min

(Here 500 mL to be infused over 6 hour, drip rate should be gtt/min, so use time conversion , and drip factor 12 gtt/ min)

gtt/ min =   × × ( cancel out hour and mL from numerator and denominator)

gtt/min =

gtt/min = 16.6666

gtt/min = 17 gtt/min

Question : A patient who weighs 74 pounds has an order for Advil (ibuprofen) 3.5 mg/kg every 6 hours. How many mg will you give in a single dose?

Answer : 118 mg

mg/dose = × × ( Cancel out lbs and kg from numerator and denominator )

mg/dose = mg

mg/dose = 117.727

mg/dose 118 mg

Question : A 15 pound child has an order for an antibiotic for 55 mg/kg/every 6 hours. The antibiotic comes as 1 g/25 mL. What is the amount of a single dose?

Answer : 0.38 mL

Step 1 : Calculate mg per dose

mg/dose = × ×

mg/dose = mg

mg/dose =375  mg

Step 2 : Find mL per dose

Medicine strength = 1 gm/ 25 mL, Here the medicine order is in mg so convert 1 gm to mg( ie 1gm= 1000 mg)

mL per dose =

mL per dose = (cancel out mg from numerator and denominator)

mL per dose =   mL

= 0.375 mL or 0.38 mL

Question : The order is to give 60 mg of Garamycin (gentamicin) IM every 8hr. The vial is labeled 80 mg/ 2 mL. How many mL will you give?

Answer : 1.5 mL

mL per dose =

mL per dose = (cancel out mg from numerator and denominator)

mL per dose =

mL per dose = 1.5 mL

Question : Give Pronestyl (procainamide HCl) 200 mg. The drug is available as 0.5 g/ mL. How many mL will you give?

Answer : 0.4 mL

Here available dose in g/ mL, so convert it to mg/ mL( × = 500 gm )

mL per dose =

mL per dose = (cancel out mg from numerator and denominator)

mL per dose = mL

mL per dose = 0.4 mL

Question : The recommended dose for an antibiotic is 80mg/kg/day. If the patient weighs 38 kg how many mg/day should the patient receive?

Answer : 3040 mg/day

Answer : ( cancel out kg from numerator and denominator)

= 80 38 mg/day

= 3040 mg/day
