Name the Receptor
This receptor primarily affects the heart and increases heart rate and contractility.
Beta-1
A patient receives a sympathetic agonist. What happens to the pupils?
Dilate (mydriasis)
A medication that mimics a neurotransmitter and activates receptors is called this.
Agonist
Which system causes fight or flight?
Sympathetic
These medications should be used cautiously in patients with asthma because they may cause bronchoconstriction.
Beta blockers
This receptor primarily affects the lungs and causes bronchodilation.
Beta-2
A patient receives a parasympathetic drug. What happens to GI activity?
GI activity increases
A medication that prevents receptor activation is called this.
Antagonist (blocker)
Which system causes rest and digest?
Parasympathetic
A parasympathetic drug may cause this heart rhythm change.
Bradycardia
Activation of this receptor causes vasoconstriction and increased blood pressure.
Alpha-1
A patient receives a beta blocker. What happens to heart rate?
Heart rate decreases
Beta blockers fall into this drug classification.
Antagonist
Which system causes bronchoconstriction and increased GI activity?
Parasympathetic
A strong sympathetic agonist will most likely increase these two vital signs.
Heart rate and blood pressure
Blocking this receptor can worsen asthma symptoms.
Beta‑2
Sympathetic stimulation causes this lung effect.
Bronchodilation
A drug that inhibits beta receptors and decreases heart rate and blood pressure. What type of drug is this?
Antagonist (Blocker)
This system causes increased peristalsis.
Parasympathetic
These medications may cause orthostatic hypotension.
Alpha or Beta Blockers
