1
Q
Adrenergic Agonists are also called
A
sympathomimetic
2
Q
adrenergic agonists have applications in
A
- congestive heart failure
- asthma
- preterm labor
3
Q
epinephrine receptor specificity
A
- alpha1 and alpha2
- beta1 and beta2
4
Q
Adrenergic receptor activation effect on Atrioventricular (AV) heart block
A
- enhance impulse conduction through AV node
- can help overcome AV block
- drugs= temporary form of treatment
5
Q
long term management of AV heart block
A
pacemaker
6
Q
cardiac arrest treatment
A
Epinephrine
- IV/direct injection into the heart
7
Q
anaphylactic
A
- severe allergic response
- hypotension, bronchoconstriction, edema of the glottis
8
Q
treatment of anaphylaxis
A
epinephrine
9
Q
therapeutic uses of epinephrine
A
- delays absorption of local anesthetic
- controls superficial bleeding
- elevates blood pressure
- overcomes AV block
- restores cardiac functioning during arrest
- causes bronchial dilation in patients with asthma
- treatment of choice for anaphylactic shock
10
Q
epinephrine absorption
A
- intramuscular (IM), subcutaneous (SQ), and intravenous (IV)

Q
epinephrine half life
A
short
12
