Answer 7

1 g

Question 8

Percent solutions weight

Answer 8

Xg/100mL (ie 1% is 1g/100mL, 10% is 10g/100mL)

Question 9

Percent solutions volume

Answer 9

XmL/100mL (ie 2% is 2mL/100mL)

Question 10

gtt=

Answer 10

Drops

Question 11

mcgtt

Answer 11

microdrops

Question 12

Body Surface Are dosing full formula

Answer 12

Dose = square root [(Height (cm) x Weight (kg)) / 3600]

Question 13

Rounding with syringes

Answer 13

• Amounts less than 1 mL are rounded to nearest hundredth
• decimal places. Amounts more than 1 mL are rounded to tenth

Question 14

miles to km

Answer 14

1.6miles

Question 15

Drip rate calculation

Answer 15

Total volume x drip factor ÷ time = flow rate (gtt/min)

mnemonic- “TV will make you deaf over time,” which is:

TV – total volume
Deaf = DF or drip factor
Over = divided by (or over)
Time = time prescribed by the physician

ie- 3ml/1 minute x 10gtt/3ml = 30gtt/3min = 10gtt/1min

Question 16

Drip rate shortcuts

Answer 16

For 10 gtt/ml sets, divide flow rate by 6.
For 15 gtt/ml sets, divide flow rate by 4.
For 20 gtt/ml sets, divide flow rate by 3.

Question 17

Desired dosage Formula

Answer 17

D/H x Q = X
X is Desired dose (ml)
D is ordered Dose amount
H is Amount on Hand
Quantity.

For example, a provider requests lorazepam 4 Mg IV Push for a patient in severe alcohol withdrawal. The clinician has 2 1mg/1mL vials on hand. How many milliliters should he or she draw up in a syringe to deliver the desired dose?

X= Dose ordered (4 mg) x Quantity (1 mL)/Have (2 mg) = Amount wanted to give (2 mL)

Question 18

BSA using constants

Answer 18

BSA (in m2) = k × BW2/3
K = 0.101 in dogs or 0.1 in cats X kgs or
bw = body weight

Question 19

Find a dilution formular

Answer 19

V1 × C1 = V2 × C2
V1C1 is what you have on hand

microgram

Answer 20

written as ug (u has a tail for first part
1 ug =0.000001 g

Question 21

Dosage calculations

Answer 21

Animal body weigh X mass of drug/dosage = dose

1 mL = (Drops)

Answer 27

20 gtt

Question 28

grain =

Answer 28

65 mg

Question 29

The next formula can be used to adjust the dosage (mcg/kg/min) in accordance with the response of the animal.

Answer 29

M = DWV/R16.67 M = number of milligrams of drug to add to delivery fluid D = dosage of drug in micrograms per kilogram per minute W = patient body weight in kilograms V = volume in milliliters of delivery fluid R = rate of delivery in milliliters per hour 16.67 = conversion factor

Question 30

percent change

Answer 30

change ÷ original. = percent change

Question 31

To convert a percent concentration to a ratio concentration

Answer 31

set up a ratio based on percentages Example: Convert a 3.1% solution to a ratio concentration. 3.1/100 = 1/x 3.1x/100 =1 x =100/3.1 X = 32

Question 32

Adding dose to IV fluid formula

Answer 32

Volume=Dose/concentration Add 20 mEq of potassium (KCl) to a bag of IV fluids containing 1 L (1000 mL). The concentration of potassium is 2 mEq/1mL. Volume needed = 20mEq/2mEq Volume needed = 10mEq

Question 33

Farenheit to Celsius

Answer 33

°F = (9/5 × °C) + 32

Question 34

Maintenance fluids (simple - 2 options)

Answer 34

1ml of fluid per pound of body weight per hour. 20–30 ml per pound per day.

Question 35

Fluid rate

Answer 35

daily fluid requirement and divide by 24 and give at that rate If the animal is experiencing shock, it needs its fluids a bit more quickly to help get it out of shock. Rapid administration for dogs is 40 ml/lb/hour and 20–30 ml/lb/hr in cats.
