NUR 316 | Chapter 30: Adrenergic Agonists PrepU
A nurse may be asked to administer adrenergic drugs to clients with which conditions? (Select all that apply.)
Hypovolemic shock Respiratory distress Allergic reactions Cardiac arrest
A nurse in the intensive care unit is caring for a patient in shock and has started IV administration of dopamine (Intropin). For a patient in shock, dopamine helps to:
increase blood pressure.
Which adrenergic receptor is responsible for vasodilation of peripheral vessels and bronchodilation?
β2 receptors
Which condition is treated with an adrenergic agonist?
Anaphylaxis
A nurse is providing teaching to a client just prescribed midodrine for his orthostatic hypotension. Which nursing instruction is it very important that the client understands?
"Only take midodrine when standing. Taking it while lying down can cause very high blood pressure."
The nurse is teaching a patient about safe use of adrenergic drugs. Which statement should be included in the teaching?
"Talk to your doctor before taking any other medications."
Which patient should be advised by the nurse to avoid over-the-counter cold and allergy preparations that contain phenylephrine?
A 47-year-old female with hypertension
Which patient is most likely to benefit from the administration of an adrenergic agonist?
A man who is in cardiogenic shock following a myocardial infarction
Which receptor does phenylephrine stimulate?
Alpha1
The nurse knows that which class of drugs prevents epinephrine and norepinephrine from occupying receptor sites on the cell membranes?
Beta-adrenergic blocking drugs
A patient receives a beta-specific agonist. Which would lead the nurse to determine that the drug is effective?
Bronchodilation
A patient has been administered dobutamine HCL. Which adverse reactions should the nurse monitor for in the patient?
Cardiac arrhythmias
A 21-year-old man experienced massive trauma and blood loss during a motorcycle accident and has been started on a dopamine infusion upon his arrival at the hospital. In light of this drug treatment, what assessment should the care team prioritize?
Cardiac monitoring
A nurse is caring for an elderly patient who is to be administered isoproterenol. Which change monitored in the patient should the nurse report immediately to the primary health care provider?
Changes in pulse rate
Which agent would the nurse identify as being available in a transdermal form?
Clonidine
A nurse is caring for a male client who is being given an adrenergic drug for shock. Which action should the nurse do?
Continually assess the client for physiological changes and notify the primary care provider with relevant changes.
Which would the nurse identify as a naturally occurring catecholamine?
Dopamine
Which herbs has been removed from most weight-loss medications due to potential legal liability?
Ephedra
A patient suffers from bronchial asthma. Which medication will be administered?
Epinephrine
An instructor is preparing a teaching plan for a group of students about adrenergic agonists. Which would the nurse include as an alpha- and beta-adrenergic agonist?
Epinephrine
Anaphylaxis kits for clients allergic to bee stings would contain which medications?
Epinephrine
Which would the nurse expect to be given to a patient experiencing acute bronchospasm?
Epinephrine
A nurse would instruct a patient to apply a clonidine patch at which frequency?
Every 7 days
An increased dosage of digoxin would be needed if the patient is also taking midodrine.
False
The autonomic nervous system controls which body functions? (Select all that apply.)
Heart rate Blood pressure Glandular secretions GI activity
A male client is prescribed an adrenergic ophthalmic medication. What should the nurse include in the teaching plan?
Hypertension may be a side effect of the medication.
Stimulation of beta1 adrenergic receptors in the heart results in:
Increased heart rate
Which is an effect of epinephrine?
Increased heart rate
A patient is administered epinephrine in conjunction with a local anesthetic. What effect will epinephrine produce?
Increased vasoconstrictive effects
The nurse would contact the physician before administering an adrenergic drug to a client who is also taking which drug?
MAO inhibitor
Epinephrine is contraindicated in patients with which diseases or disorders?
Narrow-angle (or closed-angle) glaucoma
Which agent would the nurse expect to find when reviewing over-the-counter allergy products?
Phenylephrine
The nurse knows that what is an added benefit of epinephrine in cardiac arrest situations due to asystole or pulseless electrical activity?
Stimulates electrical and mechanical activity
The adrenergic branch of the autonomic nervous system is also known by which name?
Sympathetic nervous system
A nurse is monitoring the vital signs of a patient who has been administered epinephrine. Which of the readings should nurse report immediately to the primary health care provider?
Systolic blood pressure below 100 mm Hg
The nurse is aware that epinephrine may be administered in what ways? (Select all that apply.)
Topical IV Inhalation
Phentolamine is the agent used to treat extravasation of dobutamine.
True
A client is in shock and is receiving dopamine. The nurse knows that the proper way dopamine should be given is by what method?
Via an electric infusion pump, by itself, and titrated to desired systolic blood pressure
Epinephrine causes relaxation of:
bronchioles
A client is taking an OTC allergy product. The nurse would expect to find that this product most likely contains:
phenylephrine
Drugs that produce activity similar to the neurotransmitter norepinephrine are known as:
sympathomimetics
Which adrenergic receptor is responsible for increased heart rate and increased force of myocardial contraction?
β1 receptors
A priority nursing assessment for a patient who is to receive an alpha- or beta-adrenergic agonist would be to:
assess heart rate.
What would a nurse expect to administer if a client who is receiving isoproterenol develops a severe reaction?
Beta-adrenergic blockers
