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


  1. What is cyclosporine
    • an immunosuppressant ~ dampens immune response by binding to the intracellular messenger calcineurin, disrupts T-cell function
    • Is a Calcineurin inhibitor
    • Treats severe inflammation
    • prevents transplant rejection
  2. What teaching would you do for cyclosporine?
    • It's an immunosuppressant
    • Avoid crowds
    • Report fever, even if it's low
    • Good hand washing, oral hygiene
    • No grapefruit juice as it will increase the levels of cyclosporine
  3. Glucocorticoids therapeutic class
    • corticosteroids
    • nonselective
    • potent inhibitors of inflammation
    • often drugs of choice for short term therapy of severe inflammation
    • *Active infection is contradiction
  4. immunostimulants
    • Few are available
    • include interferons and interleukins produced by recombinant DNA technology
    • they are hormone-like proteins the regulate intensity and duration of immune response (biologic response modifiers)
  5. Immunostimulant nursing care
    Because immunostimulants can cause immunosuppression, nurse will monitor for RBC, neutropenia (WBC) and thrombocytopenia (platelets)
  6. titers
    • Blood test for immunity
    • valid way to determine immune level or effectiveness of most vaccines
  7. Acetaminophen and drug interactions
    • Antipyretic
    • most common cause of liver failure
    • inhibits metabolism of warfarin
    • No alcohol
  8. Acetaminophen pt teaching

    • NOT anti-inflammatory
    • max 3 G/day
    • hepatoxic
  9. Glucocorticoids side effects
    • *strongest inflammatory we know

  11. NSAIDS max dosing
    3200 mg/day
  12. NSAIDS outcomes
    • Pt will have diminished fever, diminished pain, or no s/s of inflammation
    • Be free from nephrotoxicity (creatinine)
    • Have no GI bleed
  13. steroid teaching
    • Active infection is contradiction
    • must be discontinued gradually
    • abrupt withdrawal leads to adrenal insufficiency
    • *recall immunosuppressant ed and glucocorticoid assessment
  14. Antibiotics and lab tests
    • To determine most effective or if bacteria is resistant, need a culture and sensitivity test
    • To determine amount to give, MIC (minimal inhibitory concentration) is determined in a petri dish
  15. Antibiotic assessment
    • Culture to ID bacteria, perform sensitivity test.
    • Considerations:
    • Age
    • Prego?
    • Severity of illness
    • Allergies
  16. Antibiotic side effects
    • Penicillins relatively safe

    • suppression of regular flora
    • Diarrhea (C-diff or bacterial colitis)
    • UTI
  17. Antibiotic and body's natural defenses
    • The drug will stop the growth of kill some of the microbes
    • Our body's defenses kill the remaining cells
  18. Gentamicin assessment
    • Is an aminoglycoside (type of agent for bacterial infection)
    • Need to watch for hearing loss (ototoxicity, tinnitus, vertigo)
    • Also HA and nephrotoxicity
    • Used alot in hospital, narrow therapeutic range
  19. Multiple antibiotic sequelae
    • allows for lower doses of each drug
    • reduces risk for resistance and toxicity
    • Treatment common for HIV and TB
  20. TB treatment
    • Done in 2 phases:
    • Initial phase: 2 months of daily therapy w Isoniazid, Rifampin, PZA and ethambutol.  *If C&S test revels strain is resistant to first 3 drugs, ethambutol is dropped.
    • Continuation phase: 4 months of therapy w isoniazid and rifampin, 2-3 x per week

    INH (Isoiazid) most common drug to be used.

    • Prego cat D
  22. Vancomycin
    • *in antibacterial class of it's own
    • most effective drug for treating MRSA
    • Because of ototoxicity, hearing must be evaluated throughout therapy
    • When given too quickly via IV, causes red man syndrome & results in large amounts of histamine
    • Sx include hypotension w flushing & red rash in face (Hold and call MD)
    • Toxicity s/s: low urine output (nephrotoxicity)
  23. Mycoses
    fungal infection
