Pharmacology Exam 1 Chapters
1, 2,3,4 With Correct Answers
2025/2026
Advantages of dry powder inhalers (DPI's) - correct answer-small and
portable
- short preparation and administration times
-breath actuation; no need for hand-breathing coordination
-no inspiratory hold or head tilt needed
-no CFC propellants (environmentally friendly)
-no cold Freon effect to cause bronchconstriction or inhibit full
inspiration
-built-in dose counter
advantages of the pressurized dose inhalers (pMDIs)? - correct answer-
portable, light and compact
- efficient drug delivery
,-short treatment time
- easy to use
- more than 100 doses are available
- fine particles are available in hydrofluoroalkane (HFA) formulations
-difficult to contaminate
-no drug preparation is needed
-it is possible to reproduce emitted doses
describe aerosolized agents given by inhalation? - correct answer-
aerosolized drugs: medication goes into your lungs and absorbed there
- they are not pills or capsules that are swallowed
describe an orphan drug? - correct answer- a drug or biological product
for the diagnosis or treatment of a rare disease
-a rare disease effects less than 200,000 people
-also considered an orphan drug if there is no reasonable expectation
of recovering the cost of drug development ( not profitable to make
this drug that will only help less than 200,000 people)
describe an over the counter (OTC) drug? - correct answer- does not
require prescription
- can be hazardous
, -"self- treatment" could mask or complicate a serious medical condition
describe drops in units of volume? - correct answer16 drops (gtts)= 1mL
describe dry powder inhalers (DPIs)? - correct answer- main advantage
is that it is breathactuated
- inspiratory flow rate: needs between 30-90 L/min
-has 3 categories: unit-does DPIs, multiple unit-dose DPIs, multiple dose
DPI's
describe mesh nebulizer? - correct answer-move the liquid
formulations through a fine plate or mesh with multiple apertures (
small holes) to generate aerosol
-do not require a gas source, they are battery or electrically powered
-two types: active vibrating mesh nebulizer and passive mesh
nebulizers
describe nebulizers? - correct answer-encompasses various devices that
operate in a different physical principles to generate an aerosol from a
drug solution
-the small volume nebulizers (SVN): type of aerosol generator that
converts liquid drug solutions or suspensions into aerosol
describe particle size and lung deposition? (**important**) - correct
answer-a major factor influencing aerosol deposition in the lung is
particle size
-the upper airway (nose and mouth): particles less than 10 μm
