The flashcards below were created by user athors766ns on FreezingBlue Flashcards. What would you like to do?


  1. positive inotropic
    increase heart contraction
  2. positive chronotropic
    increase HR
  3. positive dromotropic
    accelerate cardiac conduction
  4. ACE inhibitors
    • -Pril
    • inhibits aldosterone secretion> prevents H20 and Na reabsorption > diuresis > decreases the preload
  5. ACE inhibitor A/E
    • hyperkalemia
    • DRY COUGH!
    • do not take when pregnant
  6. Angiotensin II receptor blocker
    • -Sartan
    • vasodilator > Decrease SVR
    • No cough
  7. B-type natriuretic peptides
    • Nesiritide
    • Vasodilator
    • increases CO
    • used for life threatening HF
  8. B-type natriuretic peptide A/E
    • hypotension
    • dysrhythmias
    • headache
    • abdominal pain
  9. phosphodiesterase inhibitors
    • -Rinone
    • +inotropic drug
    • vasodilator
    • makes the heart more effective
    • not for severe valuvlar disease and diastolic HF
  10. phosphodiesterase inhibitors A/E
    • thrombocytopenia
    • dysrhythmias (ventricular)
    • hypotension
    • angina
    • hypokalemia
    • tremors
  11. cardiac glycosides
    • Digoxin: increases heart contractility, decreases HR and conductivity
    • increase SV
    • diuresis
  12. digoxin
    • 0.5 - 2 ng/ml
    • low K levels cause digoxin toxicity
    • drug levels and electrolytes must be monitored
    • wait for labs (afternoon)!!
  13. cardiac glucosides A/E
    • dysrhythmias 
    • increase/decrease HR
    • Head ache
    • fatigue
    • confusion
    • colored halo : flickering light vision
    • N/V
    • diarrhea
  14. digoxin toxicity
    • digoxin level >10ng
    • yellow vision
    • hyperkalemia (5mEq)
    • cause heart dysrhythmias
    • antidote: digoxin immune Fab
  15. hold meds when HR is
    under 60 and above 100
  16. nitrates
    • Nitro-, isosorbide
    • vasodilator   
    • prevention and treatment of angina
  17. Nitrate A/E
    • HA, so take Tylenol
    • tachycardia
    • hypotension: LIE DOWN!
    • tolerance, so take patch off at bedtime
  18. Beta-Blocker
    • -lol
    • decrease HR
    • decrease contractility
    • block harmful effects of catecholamines after an MI
    • long term prevention of angina (not immediate)
  19. beta blocker A/E
    • bradycardia
    • hypotension
    • wheezing!
    • impotence
    • dyspnea
    • drosiness
  20. calcium channel blockers
    • -ine, verapamil, diltiazem
    • vasodilation > decrease SVR > decrease the workload on heart > decrease myocardial 02 demand
  21. Calcium channel blockers A/E
    • hypotension
    • palpitations
    • Nausea
  22. report a wt gain of
    2 lbs in a day, 5 lbs in a wk
  23. avoid alcohol and hot tubs because
    the cause hypotension > fainting
  24. expected outcome associated with digoxin
    decreased HR
  25. pts should avoid this food with digoxin
    wheat bran. (bran decreases drug absorption)
  26. nurse should assess what when receiving a positive inotropic drug.
    • lung sounds
    • daily weights
    • pulse and serum electrolytes (bradycardia, hypokalemia)
