What is the mechanism of action for adrenergic blockers?
- Answer-They block SNS neurotransmitters from binding
to adrenergic receptors.
What are critical nursing responsibilities when
administering adrenergic blockers? - Answer-Assess
allergies, hold dose if HR <60 or BP <100 systolic, monitor
for dizziness and fatigue.
What is the effect of alpha blockers on blood pressure? -
Answer-They cause vasodilation and decreased BP.
What are the therapeutic effects of beta blockers? -
Answer-Reduced heart rate, force of contraction, and
slowed impulse conduction.
What are common indications for beta blockers? - Answer-
Hypertension, angina, myocardial infarction, dysrhythmias.

What do cholinergic agonists mimic? - Answer-
Acetylcholine (ACh) to stimulate the parasympathetic
nervous system (PSNS).
What are the therapeutic effects of cholinergic agonists? -
Answer-Decreased heart rate and blood pressure,
increased salivation, urination, and GI motility.
What is a key adverse effect of cholinergic agonists? -
Answer-Bradycardia and hypotension.
What is the treatment for cholinergic crisis? - Answer-
Atropine sulfate (anticholinergic) and supportive care.
What do cholinergic blockers inhibit? - Answer-
Acetylcholine at muscarinic receptors.
What are common indications for cholinergic blockers? -
Answer-Bradycardia, asthma, GI hypersecretory
conditions, and motion sickness.

What are the adverse effects of cholinergic blockers? -
Answer-Tachycardia, dry mouth, constipation, urinary
retention.
What is the nursing responsibility for all ANS drugs? -
Answer-Assess baseline vitals, allergies, and
contraindications.
What is the nursing diagnosis related to ANS drug
administration? - Answer-Risk for injury due to orthostatic
hypotension.
What should patients be taught regarding adrenergic
blockers? - Answer-Take at the same time daily, avoid
alcohol/caffeine, and monitor HR/BP.
What is the significance of 'SLUDGE' in cholinergic
toxicity? - Answer-It represents symptoms: Salivation,
Lacrimation, Urination, Diarrhea, GI upset, Emesis.
What is the mechanism of action for indirect-acting
cholinergic agonists? - Answer-They increase
acetylcholine availability at receptor sites.
, 4|Page
What do adrenergic agonists mimic? - Answer-The effects
of the sympathetic nervous system (SNS)
What are the three types of adrenergic agonists? -
Answer-Direct-acting, indirect-acting, and mixed-action
What is the mechanism of action for direct-acting
adrenergic agonists? - Answer-They directly bind to
adrenergic receptor effector sites on smooth muscle.
What are common adverse effects of adrenergic agonists?
- Answer-Restlessness, insomnia, hypertension,
tachycardia, dysrhythmias, nausea, vomiting, muscle
cramps.
What serious toxicity can occur from adrenergic agonists?
- Answer-Seizures and hypertensive crisis.
What are the indications for adrenergic agonists? -
Answer-Medical emergencies (cardiac arrest,
hypotension, shock states, anaphylaxis) and respiratory
disorders (asthma, COPD).
