Module 1 Flashcards
Accuracy definition?
how close to “true” value
Measured value - 110cc
True value - 100cc
What is the % error?
10%
Precision definition?
agreement between replicated measurements
If standard deviation is low,
Precision high or low?
High
Density equation
D = Mass/Volume
Density of H2O
1 g/mL
Specific gravity equation
(Density of object) / 1
Specific gravity > 1 means what?
object is denser than water
Specific gravity of < 1 means what?
object is less dense than water
2.5m = ?cm
250cm
1.5g = ?mg
1500mg
1.2g = ?mcg
1,200,000mcg
2% Lido,
How many mg/mL?
20mg/mL
2% Lido,
How many mcg/mL?
20,000mcg/mL
1:200,000 Epi,
How many mg/mL?
1mg/200mL
so,
0.005mg/mL
1:200,000 Epi,
How many mcg/mL?
1mcg/0.2mL
so,
5mcg/mL
2mL of 1:150,000 Epi contains how many mcg?
1mcg/0.15mL
so,
13.33mcg/2mL
How many mg of Epi required to make 50mL of 1:200,000 solution?
1mg/200mL
so,
0.25mg
5mL of 4% cocaine,
How many mg?
40mg/mL
so,
200mg
25mL vial of 1% Lido w/ 1:500,000 Epi,
How much mg of each drug?
250mg of Lido
0.05mg of Epi
How would you make 10mL of a 2% solution from 5% stock?
4mL of 5% solution w/ 6mL dilutent
What is % concentration of solution with 5mg in 50mL?
0.1mg/mL
so,
0.01%
How many vials of 1mL 1:1,000 Epi are required to make 50mL of 1:200,000 solution?
1:1000 = 1mg/mL
1:200,000 = 1mg/200mL
so, 1 vial for 200mL
so,
0.25 vials for 50mL
1327cm = ?m
13.27m
326g = ?kg
0.326kg
3.88 x 10^5 m = ?km
3.88 x 10^2 km
Mass = 10g Volume = 5mL Density = ?
2g/mL
30C = ?K
303.15K
1” = ?cm
2.54cm
Equation for F to C
C = (F - 32)/1.8
Equation for C to F
F = (C x 1.8) + 32
1kg = ?lbs
2.21lbs
