A

Epinephrine (Adrenaline)

Q

use of epinephrine (adrenaline)

A

anaphylactic reactions

hypotensive shock

Q

alpha adrenergic agonist

A

phenylephrine (neo-synephrine)

Q

use of phenylephrine (neo-synephrine)

A

glaucoma
nasal congestion
hypotension

Q

beta 1 adrenergic agonist

A

dobutamine (Dobutrex)

Q

use of dobutamine (Dobutrex)

A

hypotension

- shock secondary to MI

Q

beta 2 adrenergic agonist

A

isoproterenol (albuterol, ventolin)

Q

use of isoproterenol (albuterol, ventolin)

A

asthma

- COPD

Q

dopamine (intropin) range

A

1 - 20 mcg/kg/min

Q

low dose action range for dopamine (inotropin)

& function

A

1 - 10 mcg/kg/min

- vasodilation of renal & mesenteric arteries

Q

high dose action range for dopamine (inotropin)

& function

A

10 - 20 mcg/kg/min

- stimulates beta 1 receptors (inotropic effects)

Q

use of dopamine (intropin)

A

ARF (acute renal failure)

- CHF (congestive heart failure)

Q

side effects of adrenergic agonists

A

hypertension
tachycardia
cardiac arrhythmias
urinary retention
cerebral hemorrhage
angina - CNS excitability
hyperglycemia
extravasation

Q

nursing implications for adrenergic agonist

A

assess VS and cardiac functions
assess urine output (decrease)
assess therapeutic response
consult MD prior to taking OTC cold medications
watch blood glucose levels in diabetics
ensure safety secondary to CNS excitability
monitor EKG for arrhythmias
assess IV for extraversion
