Q1 QUESTION 1 OF 169
what substance is a synthetic catecholamine
RESPONSE
dobutamine
RATIONALE
Dobutamine is a synthetic sympathomimetic amine that mimics the effects of catecholamines,
primarily by stimulating beta-1 adrenergic receptors. This action increases myocardial contractility
and heart rate, making it a synthetic catecholamine used to manage cardiac decompensation.
Q2 QUESTION 2 OF 169
what occurrence is an effect of beta-1 adrenergic receptor stimulation
RESPONSE
increased renin secretion
RATIONALE
Stimulation of beta-1 adrenergic receptors in the juxtaglomerular cells of the kidney triggers an
increase in renin secretion. This enzyme initiates the renin-angiotensin-aldosterone system,
leading to elevated blood pressure.
Q3 QUESTION 3 OF 169
which body parts are regulated by the ANS
Page 2
, RESPONSE
smooth muscles and glands
-eyes
-heart
-urinary bladder
-respiratory system
-GI tract
RATIONALE
The autonomic nervous system (ANS) controls involuntary bodily functions. It regulates smooth
muscles and glands, influencing organs such as the eyes, heart, urinary bladder, respiratory system,
and gastrointestinal tract to maintain homeostasis. This system operates below the level of
conscious control.
Q4 QUESTION 4 OF 169
stimulation of what receptor will cause increased heart rate
RESPONSE
Beta 1
RATIONALE
Stimulation of Beta 1 adrenergic receptors in the sinoatrial (SA) node of the heart increases the rate
of depolarization. This directly leads to an increased heart rate, a key mechanism in the sympathetic
nervous system's response.
Q5 QUESTION 5 OF 169
function of adrenergics
RESPONSE
-dilates pupils
-dilate bronchioles
-inc HR
-vasoconstriction
-relax GI
-relax bladder
-relax uterus
Page 3
, RATIONALE
Adrenergic agents stimulate alpha and beta receptors, leading to sympathetic nervous system
responses. These effects include mydriasis (pupil dilation), bronchodilation, increased heart rate,
vasoconstriction, and relaxation of gastrointestinal, bladder, and uterine smooth muscle. This
prepares the body for "fight or flight" situations.
Q6 QUESTION 6 OF 169
sympathomimetic
RESPONSE
agent that mimics the effects of the sympathetic nervous system
RATIONALE
This term describes a substance that activates the same receptors as endogenous sympathetic
neurotransmitters like norepinephrine. These agents produce effects such as increased heart rate,
bronchodilation, and vasoconstriction, mirroring the body's "fight or flight" response.
Q7 QUESTION 7 OF 169
Parasympatholytic
RESPONSE
agent blocking or inhibiting the effects of the parasympathetic nervous system
RATIONALE
A parasympatholytic agent functions by antagonizing the action of acetylcholine at muscarinic
receptors. This blockade inhibits the effects of the parasympathetic nervous system, leading to
responses such as increased heart rate and bronchodilation.
Q8 QUESTION 8 OF 169
alpha 1 receptors
