Convert 0.086 L to mL
96 mL
first change cups to mls = 4.5 x 240 mls = 1080 ml
1080 ml divide by 1000 = 1.08 L
Convert 2 pt (pints) to mL.
480 mls = 1 pint
480 mls x 2 = 960 mL
If a liquid drug contains 400 mg of drug per 5 mL, how many L are required to supply 1 g of drug.
Round to the hundredths place value
First convert 1 gram = 1000 mg
400 mg/5 mls = 1000 mg/xmL = 12.5 mL
12.5 mL to L /1000 = 0.0125
0.01 is the answer
The final form of a w/w mixture is likely a suspension
False
w/w = grams in grams- common in ointments, creams and powders= ex. 5 g in 100 g cream
w/v = grams in mL=ex. 10 g in 100 mL solution
v/v = mL in mL = ex. 70 mL in 100 mL solution
Convert 0.008 g to mcg
8000 mcg
is the following statement true or false?
iiss tsp = 2.5 mls
2.5 teaspoons = 12.5 mls (2.5 x 5 mls)
Convert 22 lb. to kg.
Convert 7.5 lb. to kg.
Convert 42 kg to lb.
10 kg
3.4 kg
92.4 lbs
How many drams are needed to provide 3 g of medication if the solution is available as 1400 mg/7 mL?
Round to the nearest hundredth place
1 dram = 5 gm
3 g = 3000 mg
1400 mg/7 mL = 3000 mg/xmL = 15 mL
15 mL = 15 gm/5 = 3 drams answer
Convert 400ppm w/v to mg/mL
0.4 mg/mL
1 ppm w/v = 1 mg of solute per 1 L of solution
300 ppm w/v = 400 mg per 1 L of solution
1 L = 1000 mL
400 mg per 1000 mL = 0.4 mg/mL
Convert the following measurements to grams
Round to the nearest tenths decimal place
72.5 kg =
72500 g
Convert the following measurement to milligrams:
iiss tsp =
Round to the nearest hundredth place
12.5 mls to mg = 12.5 mls x 1000
12500 mg
Convert iii fl. oz. to mL.
Convert viss fl. oz. to mL.
1 fluid oz = 30 mL
3 fluid oz = 90 mL
6.5 fluid oz = 195 mls
A patient takes 2 tbsp of amoxicillin 160 mg/3 mL. How many grams are in one dose?
Round to the hundredth value place
160 mg/3 mL = xmg /30 ml = 1600 mg
1600 mg to grams divide by 1000
1.6 g answer
What does 35mg% w/v mean?
35 mg solute in 100 mL solvent
Convert the following measurement to kilograms. If needed round to the hundredths decimal place:
234 511 000 mcg =
0.24 kg
Convert the following measurement to pounds:
15 c (cups) =
Round to the nearest hundredth place
1 cup = 240 mls
15 x 240 mls= 3600 mls
3600 mls = 3600 grams
7.93 lbs
Convert 150 mL to fl. oz.
Convert 13.5 oz. to g.
Convert 85 mL to fl. oz.
5 fluid oz = 150 mL divide by 30
405 g = 13.5 oz x 30 g
2.8 fluid oz = 85 mL divide by 30
If a liquid drug contains 175 mg of drug per 5 mL, how many mL are required to supply 4 g of the drug?
Round to the nearest hundredth place value
175 mg/5 ml = 4000 mg/ xml =
Answer 114.29 mL
A vaccine arrives from America. You have a refrigerator in the pharmacy that maintains a constant setting of 1 °C to 7 °C as required by Alberta Health Services for vaccines. What is the minimum temperature in °F that the side of the box can indicate for storage of the American vaccine in the refrigerator?
Round to the nearest tenths place
Formula: F = 1.8C + 32
33.8 F
Convert the following measurement to litres. If needed round to the hundredths decimal place:
24 mL =
0.02 L
Convert the following measurement to milligrams:
7 tbsp + 2.5 tsp =
7 tbsp = 15 x 7 = 105 mls
2.5 tsp = 2.5 x 5 =12.5 ml
117.5 ml x 1000 = 117,500 mg
Convert 4.5 qt (quarts) to L.
Convert 3 gal (gallon) to L.
960 ml = 1 quart
960 mL x 4.5 = 4,320 mL/1000 = 4.32 L
1 gallon = 3840 ml x 3 = 11,520/1000 = 11.52 L
A patient has a body temperature of 105°F. What is their body temperature in °C?
Formula: C = (F – 32) / 1.8
A patient has a body temperature of 37.7 °C. What is their body temperature in °F?
Formula: F = 1.8C + 32
C = (103F - 32)/1.8= 40.6 C
F = 1.8 x 37.7 + 32 = 99.9 F
