quiz 2 Flashcards
What organs are affected with cardio selective beta blockers
Heart
It only blocks Beta1
Results of Beta1 blockage
decrease in: heart rate, cardiac output, AV node conduction
What organs are affected with nonselective beta blockers
Both heart and lungs
Blocks both Beta1 and Beta2
Results of Beta2 blockage
decrease in heart rate, contractibility, AV node conduction, cardiac output, bronchodilation
What does MONA stand for?
Morphine
Oxygen
Nitrates
Aspirin
H.F
What is the first line of therapy?
Beta blockers
They slow progression of HF and need for hospitalization
H.F
What is the 2nd line of therapy?
Cardiac Glycoside (digoxin)
Take apical pulse for full min
HR needs to be 60+
Narrow therapeutic range
H.F
What are nursing considerations
Monitor HR ad rhythm changes Administer digoxin at same time Educate PT Monitor K+ levels and educate on foods Avoid antiacids within 2 hours
H.F
Diuretics?
Assist with symptom reduction
H.F
ACEs?
Block angiotensin ll production
H.F
ARBs?
For PT that do not tolerate ACE’s
Similar to ACE’s but better long term effects
H.F
Spironolactone?
Block aldosterone receptors
Promote excretion of Na+ and H2O
H.F
Beta Blockers?
1st line therapy
Improve LV ejection and slow progression of HF
H.F
Entresto?
Use for PT with Class II- IV HF instead of ACE or ARB
suppresses (-) effects of RAAS
H.F
digoxin
2nd line of therapy
narrow therapeutic range
slows electrical conduction
increases myocardial force
Digoxin toxicity
likely to occur in PT who are hypokalemic
antidote: digibind
serum levels; greater than 1.8 ng/mL
dysrhythmias, anorexia, diarrhea, abdominal pain, fatigue, weakness, blurred vision
