Autonomic Nervous System Drugs Flashcards
(20 cards)
Two types of cell actions at receptors.
Agonist and Antagonist
When monitoring a patient who is taking a cholinergic drug, the nurse will watch for which cardiovascular effect?
a. Bradycardia
b. Tachycardia
c. Vasoconstriction
d. Palpitation
a. Bradycardia
A client is given epinephrine (Adrenalin), and adrenergic agonist (sympathomimetic). The nurse should monitor the client for which condition?
a. Decreased pulse
b. Pupil constriction
c. Bronchial constriction
d. Increased blood pressure
D. Increased blood pressure
“Fight or Flight” Adrenergics
Sympathetic Nervous System
“Rest and digest” Cholinergics
Parasympathetic Nervous System
Parasympathetic stimulation releases
Acetylcholine
When benztropine (Cogentin) is ordered for a client, the nurse acknowledges that this drug is an effective treatment for which condition?
a. Parkinsonism
b. Paralytic ileus
c. Motion sickness
d. urinary retention
a. Parkinsonism
Chemicals that transmit information from one neuron to another
Neurotransmitters
The actions of adrenergic include
a. Cardiac stimulation
b. Increased blood flow to skeletal muscles
c. Peripheral vasoconstriction
d. Bronchodilation
e. Dilation of pupils
Dicyclomine (Bentyl) is an anticholinergic, which the nurse realizes is given to treat which condition?
a. Mydriasis
b. Constipation
c. Urinary retention
c. Irritable bowel syndrome
c. Irritable bowel syndrome
What adrenergic drug is used to raise blood pressure
Ephedrine
Sympathetic Stimulation releases
Norepinephrine
The nurse is aware that adrenergic drugs produce effects similar to which of these nervous systems?
a. Central nervous system
b. Somatic nervous system
c. Sympathetic nervous system
d. Parasympathetic nervous system
d. Parasympathetic nervous system
What is the prototype of beta blockers?
Propranolol
When a patient is taking an adrenergic agonist drug, the nurse expects to observe which effect?
a. Increased heart rate
b. Bronchial constriction
c. Constricted pupils
d. Increased intestinal peristalsis
a. Increased heart rate
Cholinergic receptors
Nicotinic and Muscarinic
Directly bind to receptors
direct- acting drugs
A hospitalized patient is experiencing a severe anaphylactic reaction to a dose of intravenous penicillin. Which drug will the nurse expect to use to treat this condition?
a. Ephedra
b. Epinephrine
c. Phenylephrine
d. Pseudoephedrine
b. Epinephrine
The nurse is to administer epinephrine 0.3 mg subcutaneously. The ampule contains 1 mL of medication and is labeled 1 mg/mL. Identify how many milliliters of epinephrine the nurse will give.
0.3ML
During therapy with a beta blocker, the patient notices that she has swollen feet, has gained 3 pounds within 2 days, feels short of breath even when walking around the house, and has been dizzy. The nurse suspects that which of these is occurring?
a. The patient is experiencing an allergic reaction.
b. The patient may be developing heart failure.
c. More time is needed for the patient to see a therapeutic response to the drug.
d. The patient is experiencing expected adverse effects of the drug.
b. The patient may be developing heart failure.
