Pharmacology / Fluids & NUR 210 Exam 2 2026/2027 Q&A with Clinical Rationale
Electrolytes
1
Beta-1 adrenergic receptors are located where?
CORRECT ANSWER: In the heart (only have 1 heart)
CLINICAL RATIONALE
1. Beta-1 receptors increase heart rate and contractility when stimulated.
2
Beta-2 adrenergic receptors are located where?
CORRECT ANSWER: In the lungs (have 2 lungs)
CLINICAL RATIONALE
1. Beta-2 receptors cause bronchodilation when stimulated.
3
Parasympathetic is ____________, sympathetic is ___________
CORRECT ANSWER: Cholinergic; adrenergic
CLINICAL RATIONALE
1. Parasympathetic uses acetylcholine (cholinergic); sympathetic uses norepinephrine (adrenergic).
4
Alpha-adrenergic receptors stimulate which body systems?
CORRECT ANSWER: Peripheral vascular and pupils
CLINICAL RATIONALE
1. Alpha receptors cause vasoconstriction and pupil dilation.
, 5
What is a sympathomimetic agent?
CORRECT ANSWER: Agent that mimics the effects of the sympathetic nervous system
CLINICAL RATIONALE
1. Sympathomimetics (adrenergic agonists) mimic fight-or-flight response.
6
What is a parasympathomimetic agent?
CORRECT ANSWER: Agent that mimics the effects of the parasympathetic nervous system
CLINICAL RATIONALE
1. Parasympathomimetics (cholinergic agonists) mimic rest-and-digest response.
7
What are adrenergic agents?
CORRECT ANSWER: Agents that stimulate the sympathetic nervous system
CLINICAL RATIONALE
1. Adrenergic drugs activate alpha and beta receptors.
8
Adrenergic agents cause what effect in the cardiovascular system?
CORRECT ANSWER: Tachycardia
CLINICAL RATIONALE
1. Beta-1 stimulation increases heart rate and contractility.
9
Adrenergic agents cause what effect in the respiratory system?
CORRECT ANSWER: Bronchial dilation
CLINICAL RATIONALE
1. Beta-2 stimulation relaxes bronchial smooth muscle.
, 10
Adrenergic agents cause what effect in the peripheral vascular system?
CORRECT ANSWER: Vasoconstriction
CLINICAL RATIONALE
1. Alpha-1 stimulation causes vasoconstriction.
11
Adrenergic agents cause what effect on the eyes?
CORRECT ANSWER: Dilation (mydriasis)
CLINICAL RATIONALE
1. Alpha stimulation causes radial muscle contraction (pupil dilation).
12
ADR of adrenergic agents
CORRECT ANSWER: Nervousness, insomnia, fine muscle tremors, palpitations, tachycardia, hypertension
CLINICAL RATIONALE
1. CNS stimulation and cardiovascular effects are common.
13
Cholinergic agents cause what effect in the colon?
CORRECT ANSWER: Increased peristalsis
CLINICAL RATIONALE
1. Parasympathetic stimulation increases GI motility.
14
Cholinergic agents increase what in the bladder?
CORRECT ANSWER: Bladder tone
CLINICAL RATIONALE
1. Cholinergic stimulation contracts detrusor muscle and promotes urination.
