how many grams of dextrose are in 500 ml of D5W 10g 12.5g 25 g 50 g
25 g D5W is 5g of dextrose in 100 ml 5 g of dextrose/100ml = x / 500ml 5 g x 500 ml / 100 ml = 25 g of dextrose
a prescription is written for augmentin 30 mg/kg/day BID for 7 days for a 35 lbs pediatric patient the pharmacy has augmentin 400mg/5ml in stock how much medication in ml should be administered every time?
35 lbs = 35 / 2.2 = 15.9 kg convert 35 lbs to kg multiply 30mg/kg x ______kg divide by 2 days (because the prescription says BID) make a proportion with 400mg/5ml, the augmentin in stock total dispensed drug for 1 dose: (30 mg/kg x 15.9 kg) / 2 = 238.5 mg total dispensed volume for 1 dose: 400 mg/5 ml = 238.5 mg / x x = 238.5 mg x 5 ml / 400 mg = 2.9ml
A six-year-old female patient received 3 L of normal saline in 24 hours. The standard infusion rate for pediatric patients is 75 mL/hr. How much excess normal saline in milliliters did the patient receive per hour? 15 mL 25 mL 50 mL ← this was the correct answer! 55 mL
What patient received: 3,000 mL / 24 hr = 125 mL/hr 125 mL - 75 mL = 50 mL
the pediatric dose of a medication is 25 to 100mg/kg/day given in two or three divided doses a child weighing 10kg is precribed 250 mg q6h the dose as prescribed is a drug overdose drug scheduling error appropriate medication order drug underdose
drug scheduling error calculation first, find how many mg the patient requires per day by multiplying the patients weight in kg(10kg) by the low end(25mg) and the high end(100mg) of the dosage range provided 25mg/kg/day x 10kg = 250mg/day 100mg/kg/day x 10 kg = 1000 mg/day therefore, this patient may appropriately receive 250 mg/day to 1000mg/day next, calculate the total daily mg prescribed by multiplying mg/dose by total doses/day the prescription calls for the medication to be administered EVERY 6 HOURS if given as written, this would result in 4 doses/day 250mg/dose x 4 doses/day = 1000mg/day the total daily mg is appropriate, but the medication is intended to be given only TWO or THREE times per day. the patient may experience therapeutic failure when receiving four divided doses due to the discrepancy in mg/dose and total doses/day therefore, the dose as prescribed is a drug scheduling error
convert 1 : 7500 to a percentage strength 0.013% 1.75% 7.5% 1.3%
if you are given a ratio and asked to convert it to PERCENTAGE STRENGTH - simply divide 100 by the ratio value 100 / 7500 = 0.013%
