Drug Calc Fluid Therapy

Question 1

Describe the basic calc rules.

Answer 1

-changing units on fraction

Question 2

Describe metric units.

Answer 2

-meter, gram or second

Question 3

Describe weight/volume & %.

Answer 3

% = g / 100 mL

Question 4

Describe weight/volume & fraction.

Answer 4

• 1:1000 = ‰ = g / 1,000 mL
= … mg/mL
• 1:10000 = g / 10,000 mL
= … mg/mL
• 1:100,000 = g / 100,000 mL
= … mg/mL

Question 5

Describe weight/weight.

Answer 5

% = kg / 100 kg = g / 100 g

Question 6

Describe dilution of volume solutions.

Answer 6

-V1 & V2 in same vol units: mL, dL, L
-C1 & C2 in same conc units: %, mg/mL

Question 7

Describe dosage.

Answer 7

-amount of drug per unit BW
(1 kg = 2.2 lbs)
-amount of drug per unit surface
-determine dose to administer based on weight

Question 8

Describe dose.

Answer 8

-amount of drug administered
-units of weight & quantity
-determine vol to administer based on conc in product (on label)

Question 9

Describe rate.

Answer 9

-dosage = amount of fluid per kg of BW per time
-dose = amount of fluid per time
>determine vol (drops) to administer

Question 10

Describe constant rate infusion. (CRI)

Answer 10

-dosage per time
>amount of drug per unit BW per time
-dose per time
>amount of drug per time
-rate
>vol per time
