(*There are actually 29.57 mL in 1 fl oz, but 30 mL is usually used by nurses in medical facilities. We will stay with this standard for all liquid measurements. 1 oz=30mL, 1 c=240mL, 1 pt=480mL, 1 quart=960mL.)
QUESTIONS:
1. The patient weighs 50 lb. The physician orders 30 mg/kg/day of a certain medication. How many mg do you give in one day?________mg/day(round to the nearest whole number)
(Remember not to round till the very end)
2. The nurse is preparing potassium bicarbonate (TriLyte) for a pediatric client scheduled for a colonoscopy. The directions state to provide the prep at an estimated rate of 25 mL/kg/hr. The child weighs 55 lb. The nurse should encourage the child to drink approximately how much of the solution each hour? (round to the nearest 1/2 a cup.)
Group of answer choices
a. 2 cups
b. 3 cups
c. 3.5 cups
d. 2.5 cups
1 cup
3. The nurse receives orders to start metronidazole (Flagyl) 50 mg/kg/24 hours divided into three equal doses for a child that weighs 33 lbs. The medication is provided in 250-mg tablets. How many tablets will the nurse provide with each dose?_____tablets
Question 1
Given
Weight:50lbs(0.454×50=22.7kg)
Order:30mg/kg/day
That is 1kg=30mg
Then 22.7kg=??mg
Cross multiply and divide
=22.7×30÷1
=681mg/day
Upon rounding off to nearest whole number it will be 600mg
Ans:600mg/day
Question 2
Given
Med:Potassium bicarbonate
Weight:55lbs (0.454×55=24.97kg or 25kg)
25ml/kg/hr
That is 1kg=25ml
So 25kg=??ml
Cross multiply and divide
=25×25÷1
=625ml/hr
As 1cup = 240ml
Then 625ml=??cup
Cross multiply and divide
=625×1÷240
=625÷240
=2.6 cup
Upon rounding off to the nearest half cup it is 2.5 cups
Ans:2.5 cups
3.Given
Medication:Flagyl
Order:50mg/kg/24hour
Frequency:Three times a day
Weight:33lvs(0.454×33=14.9 or 15kg)
As 1kg=50mg
Then 15kg=??mg
Cross multiply and divide
=15×50÷1
=750÷1
=750mg/24 hour or 750mg in three divided doses for a day
Available:250mg/tab
When 1tablet=250mg
Then 750mg=??tablet
Cross multiply and divide
=750×1÷250
=750÷250
=3 tablet /24 hr
So to calculate 1 time dose 750 ÷3 =250 mg ,which means 1 tablet per dose
Ans:The nurse has to provide 1 tablet in each dose
