Week 2

Question 1

examples of sub drugs

Answer 1

insulin, epoetin alfa, heparin

max volume: 1/5 ml

Question 2

intramuscular

Answer 2

• Preferred over subq when larger volume of drug is administered
• Max volume: 2-2.5 mL in deltoid and thigh muscles,5 mL in gluteus maximus
• Examples: vaccines, antibiotics, hormone injections

Question 3

How would you dispense Epogen 30,000

units Sub-Q x 1 order?

Answer 3

40,000 units/mL x 1 vial

Question 4

IV push (IVP)

Answer 4

• Small volume administered AT LEAST over 1 min
• More concentrated
• Pushing medication from a syringe directly into
the patient’s vein
• Can induce adverse drug reactions

Question 5

• IV intermittent infusion: short infusions

Answer 5

Meds delivered over a set period of time at
prescribed intervals
• Infused by gravity or via IV pump
ex vancomycin 1 gram infused over 1 hour every 12 hours

Question 6

• IV intermittent infusion (set period of time) and continuous infusions (delivered over 24 hours)

Answer 6

medications are admixtured into a bag and delivered to patient utilizing iv pumps

Question 7

Each institution must have

Answer 7

e IV guidelines/policies that indicate which meds can be given as IVP vs IVPB

Question 8

as gauge number increases

Answer 8

size of lumen decreases

Question 9

small gauge needle

Answer 9

thick or viscous solutions (i.e 18 G)

Question 10

large gauge needle

Answer 10

aqueous solutions (i.e. 22 G)

Question 11

Filter needle/Filter straw

Answer 11

5 microns- maximum pore size necessary to
prevent particulate matter from passing
through the needle

Question 12

vented needle

Answer 12

• Positive and negative pressure must be
accounted for when withdrawing solutions from
a vial; prevents pressure differences

Question 13

ampules

Answer 13

• Glass containers that store sterile solution

* Single use

Question 14

vials

Answer 14

Contents can be in various forms

• Solution
• Freeze-dried sterile powder

Question 15

single use

Answer 15

no preservatives

Question 16

multiple use

Answer 16

preservatives added

- Anything that contains preservatives SHOULD NOT be use for epidural or intrathecal administration

Question 17

IV admixture

Answer 17

• Add drug into a larger diluent for a final

product

Question 18

Adaptable systems

Answer 18

Allow direct attachment of the drug
vial to the bag of diluent
i.eAdd-vantage, add-EASE

Question 19

- a plasticizer that is commonly added to
polyvinyl chloride (PVC) as a softener

Answer 19

Diphthalate (DEHP)
• Causes adsorption and leaching
some need to be made NON-PVC, Non-DEHP bc the rates of the absorptions are higher in those medications

Question 20

IVPB

Answer 20

need to be made in a diluent bag

Question 21

typical iv bag sizes

Answer 21

50 mL, 100 mL, 150 mL, 250 mL, 500 mL

Question 22

dose

Answer 22

• Sometimes referred by “per kg” when medication is weight based
• i.e dopamine 1 mcg/kg/min- stating the total dose per kg ( 70 mcg/min) has no meaning
- “ Pt is on dopamine @ 1”
• i.e propofol 50 mcg/kg/min
- “pt is on propofol @ 50”

Question 23

• Sometimes referred by total dose when medication is not weight based

Answer 23

• i.e insulin drip @ 5 units/hr

* i.e fentanyl drip @ 50 mcg/hr

Question 24

concentration is needed to calculate

Answer 24

the rate that corresponds to the dose
