Epinephrine

An increased dosage of digoxin would be needed if the patient is also taking midodrine.

False

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.

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

Systolic blood pressure below 100 mm Hg

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

True

A client experiencing a serious allergic reaction to a bee sting is brought to the emergency department. The client's right hand is swollen, red, and painful. She is extremely upset, short of breath, and the nurse detects wheezing and stridor. The nurse is ordered to administer epinephrine to relieve which of the clients symptoms?

acute bronchospasm.

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.

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

increased heart rate

phentolamine.

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

sympathetic
