Administer phentolamine to the site.

Which condition is treated with an adrenergic agonist?

Anaphylaxis

Phentolamine is the agent used to treat extravasation of dobutamine.

True

A client is being treated for asthma. What would the nurse expect to administer?

Beta-2-specific adrenergic agonist

What would a nurse expect to administer if a client who is receiving isoproterenol develops a severe reaction?

Beta-adrenergic blockers

A client receives a beta-specific agonist. What 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

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 nurse is reviewing the history of a patient who is to receive midodrine. Which would alert the nurse to a contraindication for the drug?

Glaucoma

Which is an effect of epinephrine?

Increased heart rate

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.

Epinephrine causes relaxation of:

bronchioles

Adrenergic drugs increase the potential risk for what adverse effect?

cardiac arrhythmias

The nurse is admitting a client with injuries following a bicycle crash. When reviewing the client's pre-admission medication regimen, the nurse reads that the client takes formoterol twice daily. When planning this client's care, the nurse should include:

frequent respiratory assessments.

The stimulation of beta1 adrenergic receptors in the heart by epinephrine would cause what result?

increased heart rate

A client is taking an OTC allergy product. The nurse would expect to find that this product mostlikely contains:

phenylephrine

Adrenergic drugs mimic the effects of stimulating what part of the nervous system?

sympathetic

A nurse suspects that a client is experiencing shock based on which assessments? Select all that apply.

Cyanosis, Disorientation, Tachypnea

Epinephrine can be administered by multiple routes. Which is not an appropriate route?

Oral

Which agent would the nurse identify as being available in a transdermal form?

Clonidine

The home health nurse is caring for a 77-year-old male patient who has just been discharged from the hospital. The patient is taking dobutamine for congestive heart failure. What would be most important to monitor in this patient?

Compliance with drug regimen

A nurse is caring for a 25-year-old client who has been prescribed an adrenergic drug for shock. Which action should the nurse implement?

Continually assess the client for physiological changes and notify the primary care provider with changes.

The nurse is assessing a client in the emergency department who has taken an overdose of phenylephrine. What symptoms should the nurse be alert for in this client? (Select all that apply.)

Dizziness, headache, seizures

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

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 would the nurse expect to be prescribed to a client experiencing acute bronchospasm?

Epinephrine

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.

Which assessment finding would indicate to the nurse that the administered isoproterenol is effective?

Improved cardiac contractility

A client is administered epinephrine in conjunction with a local anesthetic. What effect will epinephrine produce?

Increased vasoconstrictive effects

A patient is receiving salmeterol. The nurse would expect this drug to be given by which route?

Inhalation

A home care nurse is visiting a patient to assess blood pressure and heart rate. The patient's grandson has a large amount of pseudoephedrine (Sudafed) in the kitchen. For what might the nurse suspect the patient's grandson is using the pseudoephedrine?

Methamphetamine production

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
