PrepU chapter 24 Drug Adrenergic Drugs
A client with significant burns develops shock and requires adrenergic drug therapy. The nurse interprets this as which type of shock?
Hypovolemic
A group of nursing students are reviewing information about the types of shock. The students demonstrate understanding of the information when they identify which as occurring from a significantly diminished blood volume?
Hypovolemic shock
A priority nursing assessment for a client who is to receive an alpha- or beta-adrenergic agonist would be to which action?
assess heart rate.
A nurse in the intensive care unit is caring for a client in shock and has started IV administration of dopamine (Intropin). For a client in shock, dopamine helps to:
increase blood pressure.
A nurse is caring for a client who has been receiving an adrenergic medication. Which statement by the client alerts the nurse about an adverse effect of the medication and a reason to call the prescriber?
"I feel a "fluttering" feeling in my heart."
The client has been prescribed norepinephrine. While the nurse is teaching the client about this medication, the client asks the nurse what is it for. What is the nurse's best response?
"It is a neurotransmitter that keeps the nerve message going from the brain to the organ."
Which client is most likely to benefit from the administration of an adrenergic agonist?
A man who is in cardiogenic shock following a myocardial infarction
A client goes to his primary care provider for a cut finger. The provider is going to put sutures into the tip of the client's finger. Lidocaine with 2% epinephrine is ordered verbally by the provider. What should the nurse do?
Ask if he really wants epinephrine in the lidocaine since he is working on the tip of the finger. The nurse remembers from her reading that epinephrine is contraindicated in fingertips.
The nurse knows that which class of drugs prevents epinephrine and norepinephrine from occupying receptor sites on the cell membranes
Beta-adrenergic blocking drugs
An 80-year-old client has been brought to the Emergency Department in shock. The client is receiving dopamine . The nurse should prioritize the assessment for what potentially serious adverse effect?
Cardiac arrhythmia
Mrs. Kelly Johnson, aged 46, was admitted to the hospital due to prior myocardial infarction, or heart attack. The diagnostic test revealed that her heart was unable to pump enough blood to adequately perfuse the vital organs. What type of shock does she seem to have suffered from?
Cardiogenic shock
A client suffering an acute myocardial infarction may develop which type of shock?
Cardiogenic--obstructive shock
A nurse is caring for a 25-year-old 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 changes
A nurse is caring for a 25-year-old 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 changes.
The nurse is to adminsiter to the client regular doses of epinephrine as prescribed. Which nursing diagnoses is most appropriate for this client?
Disturbed Sleep Pattern, Insomnia Related to CNS Excitation
Which herbs has been removed from most weight-loss medications due to potential legal liability?
Ephedra
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
Which is an effect of epinephrine?
Increased heart rate
The nurse is writing a plan of care for a client receiving an alpha-specific adrenergic agonist. What is the priority component of client's plan of care?
Monitoring blood pressure and heart rate frequently
A 16-year-old client arrives at the emergency department (ED) stung by a bee and used zn EpiPen prior to arriving in the ED. The client is breathing well now. What would the nurse do next for this client?
Obtain from the client as much information about the bee sting and physical reaction to the sting as possible
After reviewing the routes of administration for beta-specific adrenergic agonists, a group of students demonstrate the need for additional study when they identify isoproterenol as being administered by which route?
Oral
A client was brought by ambulance into the emergency department. The client appears disoriented, pale, tachycardic, and hypotensive. There is excessive bleeding from the head and bruises across the check and abdomen. What is the priority step in managing this client?
Provide basic life support while attempting to treat hypovolemic shock.
When describing the adrenergic branch of the autonomic nervous system to a group of nursing students, the instructor would also refer to it as which type of nervous system?
Sympathetic nervous system
When transcribing new orders for sympathomimetic medications prescribed for a geriatric client, the nurse expects the dosage will be what?
The lowest possible effective dosage
A nurse is preparing to administer an adrenergic agent for shock. Which nursing assessment should be completed quickly and accurately?
Vital signs
In providing care to a client with wheezing, the nurse knows that a medication targets which receptors?
beta 2
Epinephrine causes relaxation of:
bronchioles
Adrenergic drugs increase the potential risk for what adverse effect?
cardiac dysrhythmias
A client is administered epinephrine in conjunction with a local anesthetic. What effect will epinephrine produce
increased vasoconstrictive effects
Another name for adrenergic drugs is:
sympathomimetic drugs
Which of following adrenergic receptors is responsible for decreased tone, motility, and secretions of the GI tract? (Choose one)
α2 receptors
Which of the following adrenergic receptors is responsible for increased heart rate and increased force of myocardial contraction?
β1 receptors
