Med admin (Mod 6) Flashcards
five rights med admins
- Right patient
- Right Time
- Right drug
- Right dose
- Right route
3 types of drug calculations
- Prepared strength doses
- Doses from solutions with concentration expressed as a percentage
- IV dose calculations
When are the 3 checks for the right drug?
- When getting the med
- Before admin
- Before putting away
4 drug routes
- Inhaled
- Instilled
- Intravenous
- Injection (intradermal, subq, intramscular)
Unit conversion: how many mls are in 1 teaspoon
- 1mL = 1000uL
- 1g = 1000mg
- 1mg = 1000mcg
- 1 measuring teaspoon = 5 mL
Unit conversion: how many uL in 1 mL?
- 1mL = 1000uL
- 1g = 1000mg
- 1mg = 1000mcg
- 1 measuring teaspoon = 5 mL
What does the percentage in a drug refer to in terms of active drug available?
- I.E 4% lidocaine
Percentage refers to the amount of active ingredient (solute) in a preparation containing 100 parts of the total preparation (solute and solvent)
- Weight to weight: grams per 100 g of mix
- Weight to volume: grams per 100 ml of mix
- Volume to volume: ml per 100 ml of mix
How do you drug amount by percentage strength?
Move the decimal 1 place to the right and it becomes the drug amount in mg/ml…Example below:
- (10% = 100 mg/ml, 1% = 10 mg/ml)
- for the first example above, there is 100mg/ml of active ingrediant
main uses of aerosol therapy (3)
- Humidification of dry inspired gases
- Improved mobilization and clearance of respiratory secretions (using bland aersols, hyper/hypotonic saline)
- Delivery of aerosolized rugs to the respiratory tract
Particle size that deposits in mouth and nose?
10-15 um
Particle size that deposits into large airways, first 6 generations?
5-10 um
Particle size that deposits into the small airways, last 6 generations?
1-5 um
Particle size that deposits into the alveoli?
0.8-0.3 um
What is Mass Median Aerodynamic Diameter (MMAD)
Where the mass of drug is centered in a distribution of particle sizes
- 50% of the mass of particles will be above this size, 50% will be below this size
Why is Mass Median Aerodynamic Diameter (MMAD) important?
Determines which nebulizer to use to deliver medication to target area
