Changes is pulse rate

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.

After reviewing the topic of catecholamines, a group of students demonstrates the need for additional study when they identify which as a synthetic catecholamine?

Dopamine

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?

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

The client is given epinephrine for an exacerbation of asthma. What response to the medication would the nurse expect?

Increased ease of breathing and increased heart rate

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

Increased vasoconstrictive effects

The nurse would contact the health care provider before administering an adrenergic drug to a client who is also taking which drug?

MAO inhibitor

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

Phenylephrine

Which agent would the nurse expect to find when reviewing over-the-counter allergy products?

Phenylephrine

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

Phentolamine is the agent used to treat extravasation of dobutamine.

True

Patients who are receiving alpha-specific adrenergic agents should not stop taking the drug abruptly.

True`

A client has an IV of dopamine administered in the right arm. The IV becomes dislodged from the vein and dopamine has been being given in the surrounding tissue instead of the vein. The nurse should stop the IV and:

administer phentolamine (an alpha adrenergic blocking drug) to the site to minimize necrosis.

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

A patient has been administered dobutamine HCL. Which adverse reactions should the nurse monitor for in the patient?

cardiac arrhythmias

Adrenergic drugs increase the potential risk for what adverse effect?

cardiac dysrrhythmias

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

Adrenergic drugs produce which effect?

increased heart rate

An adrenergic drug would be prescribed to produce what physiological effect?

increased heart rate
