Mechanical Ventilation Chapter 13 Questions And
Answers 2025/2026
two primary purposes of drug therapy for patients using mechanical ventilation
are that they - CORRECT ANSWER--provide patient comfort
-facilitate airway management and mechanical ventilation
for the ventilator patient, airway distress may be caused by - CORRECT ANSWER--
preexisting airway disease
-drug-induced bronchospasm
-accumulated secretions
-mechanical irritation
the autonomic nervous system comprises - CORRECT ANSWER-motor neurons
that innervate tissues under involuntary control
important functions regulated by the ANS are - CORRECT ANSWER--respiration
-heart rate
-blood pressure
-perspiration
,-glandular secretions
adrenergic response = - CORRECT ANSWER-sympathetic pathway terminal axon
uses the neurotransmitter substance epinephrine
the neurotransmitter substance released at the terminal axon of the
parasympathetic fiber is - CORRECT ANSWER-acetylcholine
sympathetic branch = - CORRECT ANSWER-stimulation
parasympathetic branch = - CORRECT ANSWER-inhibition
sympatheticmimetic bronchodilators are - CORRECT ANSWER--adrenergic agonist
-drugs dilate the airways by stimulating the beta-2 receptors of the sympathetic
nervous system
parasympatholytic bronchodilators are - CORRECT ANSWER--anticholinergic
bronchodilators
-drugs that dilate the airways by inhibiting the parasympathetic branch of the ANS
catecholamine (norepinephrine, epinephrine) have characteristics of - CORRECT
ANSWER--rapid onset
-rapid degradation
, -ineffective when taken enterally
-nonspecific receptor binding
catecholamine derivatives (metaproterenol, albuterol, terbutaline, piruterol) have
a more complex - CORRECT ANSWER-chemical structure than catecholamine
adverse effects of adrenergic bronchodilators (first class of bronchodilator)
include - CORRECT ANSWER--tachycardia
-palpitations
-skeletal muscle tremors
-nervousness
alpha-1 major effects - CORRECT ANSWER--vasoconstriction
-constriction of pupils
alpha-2 major effects - CORRECT ANSWER--decreased gastrointestinal activity
beta-1 major effects - CORRECT ANSWER--positive inotropic effect (increase
muscular contractility)
-positive chronotropic effect (increase HR)
beta-2 major effects - CORRECT ANSWER--bronchodilation
-peripheral vasodilation
