.(helper)
Part .of .the .peripheral .adrenergic .receptor .subtypes .(epi/norepi)
Beta2 .agonists .cause .relaxation .of .the .uterine .muscles, .slowing .or .stopping .the

.during .a .clinical .rotation .at .the .hospital.
Which .statement .by .a .student .demonstrates .a .need .for .further .teaching? .-
.CORRECT .ANSWER-"Beta2 .activation .results .in .contraction .of .the .uterine
.muscles"
*Beta2 .activation .DOES .result .in .vasodilation .of .skeletal .muscles,
.bronchodilation, .and .glycogenolysis, .and .RELAXATION .of .uterine .muscles*
A .provider .is .teaching .a .patient .about .a .medication .that .alters .the .sympathetic
.nervous .system .functions. .To .evaluate .understanding, .the .provider .asks .the
.patient .to .describe .which .functions .the .sympathetic .nervous .system .regulates.
Which .answer .indicates .the .need .for .further .teaching? .- .CORRECT .ANSWER-
"The .digestive .functions .of .the .body" .
All .apart .of .the .sympathetic .nervous .system:
1. .fight .or .flight
2. .cardiovascular .system
3. .body .temperature
A .patient .is .experiencing .toxic .side .effects .from .atropine, .including .delirium
.and .hallucinations.
Which .medication .will .the .provider .ask .the .nurse .to .administer? .- .CORRECT
.ANSWER-Physostigmine .(Mestinon, .Regonol)
Drug .of .choice .for .treating .poisoning .from .atropine .and .other .drugs .that .cause
.muscarinic .blockage .ie: .atropine .(Muscarinic .Antagonist)
What .drug .is .used .to .treat .Alzheimer's .Disease? .- .CORRECT .ANSWER-
Donepezil
A .patient .who .has .myasthenia .gravis .will .be .taking .neostigmine.
What .should .the .nurse .emphasize .when .teaching .this .patient .about .the
.medication? .- .CORRECT .ANSWER-Take .a .supplementary .dose .before .exercise
You .have .ordered .pilocarpine. .You .understand .that .the .drug .stimulates
.muscarinic .receptors.
Which .action .would .you .expect .the .drug .to .have? .- .CORRECT .ANSWER-
Lowering .of .intraocular .pressure .in .pts .with .glaucoma
Also .used .to .treat .dry .mouth .because .it .increases .salivary .glands ."Rest .and
.digest"
Muscarinic .agents .are .related .to .parasympathetic .response
You .are .teaching .a .nursing .student .about .the .two .classes .of .adrenergic .agonist
.drugs.
, Which .statement .by .the .nursing .student .indicates .understanding .of .the
.teaching? .- .CORRECT .ANSWER-Catecholamines .often .require .continuous
.infusion .to .be .effective .
Catecholamines .undergo .rapid .degradtion .by .monoamine .oxidase .MAO .and
.COMT. .Brief .duration .of .action .and .continuous .IV .to .be .effective .
They .DO .NOT .cross .the .BBB, .noncatecholamines .do
Noncatecholamines .can .be .given .orally .but .catehcholamines .can .not
Because .they .cause .vasoconstriction, .alpha1-adrenergic .agonists .are .especially
.useful .for .__________. .- .CORRECT .ANSWER-causing .hemostasis .in .skin .and
.mucous .membranes .
Example .is .epinephrine .
These .agents .can .increase .BP .but .are .not .the .primary .drug .used .except .in
.emergency .situations
A .nursing .student .asks .you .why .epinephrine, .and .no .other .adrenergic .agonists,
.is .used .to .treat .anaphylactic .shock.
What .will .you .tell .the .student? .- .CORRECT .ANSWER-Epinephrine .has .the
.ability .to .activate .multiple .types .of .adrenergic .receptors .
Beta .1 .receptors .increase .CO .and .BP .
Beta .2 .receptors .increase .bronchodilation
Alpha .1 .receptors .causes .vasoconstriction .and .increases .HR .and .BP
Dopamine .is .administered .to .a .patient .who .has .been .experiencing .hypotensive
.episodes.
Other .than .an .increase .in .blood .pressure, .which .indicator .would .the .nurse .use
.to .evaluate .a .successful .response? .- .CORRECT .ANSWER-Increase .in .urine
.output .because .of .the .increase .in .cardiac .output .which .was .a .result .of .the
.increase .in .BP
A .patient .is .taking .a .beta-adrenergic .antagonist .medication .for .angina .pectoris
.and .asks .the .nurse .how .the .drug .works .to .relieve .the .discomfort .associated
.with .this .condition.
Which .statement .by .the .patient .after .the .nurse's .teaching .indicates
.understanding .of .the .drug's .effects? .- .CORRECT .ANSWER-Helps .reduce .the
.heart's .oxygen .needs
Blocking .beta .1 .receptors .in .the .heart .reduces .cardiac .work .by .reducing .HR,
.force .of .contraction, .and .the .velocity .of .impulse .through .the .AV .node
Beta .blockers .results .in .bronchoconstriction .
