CSE RESPIRATORY I COMPLETE PREPARATION
GUIDE WITH OXYGENATION AND
VENTILATION PRINCIPLES REVIEW
◉ Why does aerosolized bronchodilator therapy work faster than
oral bronchodilator tablets?
Answer: Aerosolized therapy delivers medication directly to airway
receptors in the lungs, producing faster bronchodilation with less
systemic absorption than oral therapy.
◉ Which aerosol delivery system is most appropriate for a patient in
severe respiratory distress with poor inspiratory effort?
Answer: A small-volume nebulizer because it does not require
strong inspiratory flow or coordination like a DPI or pMDI.
◉ Which autonomic response causes bronchodilation and increased
heart rate?
Answer: Sympathetic nervous system stimulation.
◉ Which autonomic response causes bronchoconstriction and
slowing of the heart rate?
Answer: Parasympathetic nervous system stimulation.
,◉ What is the primary physiologic effect of alpha receptor
stimulation?
Answer: Vasoconstriction, smooth muscle contraction, and
mydriasis.
◉ What is the primary physiologic effect of beta-1 receptor
stimulation?
Answer: Increased heart rate and increased myocardial contractility.
◉ What is the primary physiologic effect of beta-2 receptor
stimulation?
Answer: Relaxation of bronchial smooth muscle causing
bronchodilation.
◉ What receptor spillover is most likely responsible for tachycardia
during bronchodilator therapy?
Answer: Beta-1 receptor stimulation from excessive beta agonist
exposure.
◉ Why are dry powder inhalers (DPIs) often poor choices during
severe respiratory distress?
Answer: DPIs require adequate inspiratory flow to disperse
medication powder, which severely distressed patients may not
generate.
, ◉ What is the major difference between a jet nebulizer and a mesh
nebulizer?
Answer: A jet nebulizer is gas powered, while a mesh nebulizer uses
electrical vibration to push medication through a perforated mesh.
◉ What type of nebulizer uses high-frequency sound waves to
aerosolize medication?
Answer: Ultrasonic nebulizer.
◉ What is one of the most important aerosol therapy principles
tested on the NBRC exam?
Answer: The medication and delivery device must match the
patient's clinical condition.
◉ Why might choosing a DPI for a patient in severe distress be the
wrong answer on a TMC exam?
Answer: Because the delivery device is inappropriate for the
patient's inspiratory ability.
◉ Which medication class should the therapist expect FIRST for a
patient with acute bronchospasm?
Answer: Short-acting beta-2 agonist (SABA) therapy such as
albuterol.
