1
Q
Infusion rate formula?
A
Volume (mL) ÷ Time (hours) = mL/hour
2
Q
Infusion: 1500 mL over 12 hrs
A
1500 ÷ 12 = 125 mL/hr
3
Q
Drops per minute formula?
A
(Volume × Drop Factor) ÷ Time (minutes)
4
Q
Give 500 mL over 5 hrs using 20 gtt/mL
A
(500 × 20) ÷ (5 × 60) = 33.3 ~ 33 gtt/min
5
Q
Microdrop set drop factor?
A
60 gtt/mL
6
Q
Macrodrop set drop factor?
A
20 gtt/mL
7
Q
1% solution = ? mg/mL
A
10 mg/mL
8
Q
0.5% solution = ? mg/mL
A
5 mg/mL
9
Q
1 in 1000 = ? mg/mL
A
1 mg/mL
10
Q
1 in 10,000 = ? mg/mL
A
0.1 mg/mL
11
Q
Give 0.5 mg from 1 in 1000 solution
A
0.5 ÷ 1 = 0.5 mL
12
Q
Give 2 mg from 1 in 1000 solution
A
2 ÷ 1 = 2 mL
13
Q
Give 3 mg from 1 in 10,000 solution
A
3 ÷ 0.1 = 30 mL
14
Q
What does 1 in 100 mean?
A
1 g in 100 mL or 1% = 10 mg/mL
15
Q
Convert 0.75 g to mcg
A
0.75 g = 750,000 mcg
