bactericidial
kill the bacteria by disruption of the cell wall
what antibiotics are included in SILLY CEPH’s CAMO
penicillin, cephalosporins, carbapenems, monobactams
glycopeptide
-antibiotic
-vancomycin: #1 treatments for C Diff, narrow therapeutic index, treat with peak and troughs, 2nd treatment for C Diff: metronidazole
tobramycin
-used for eyes
-amino-glycosides: narrow therapeutic index, treat with peak and trough, nephrotoxic and ototoxic
bacteriostatic
preventing bacterial growth and replication by inhibiting protein synthesis
clindamycin
antibiotic, #1 cause of C Diff
Erythromycin
-group macrolide
-causes QT prolongation (torsade’s de pointes)
-take if your have a PCN allergy
- pregnant women can take this
-take with food
broad-spectrum antibiotics
-used before culture and sensitivity
-typically have a wide range of bacteria that they target
narrow spectrum antibiotics
-after culture and sensitivity
-identify the bacteria and how best to treat it
-we can use narrow spectrum to focus on the bacteria causing infection
wound cultures (when should they be done)?
-C&S should be done to distinguish and narrow the spectrum the antibiotic
-which helps prevent antibiotic resistant pathogens
why are the resistant strains of antibiotics?
-some resistant bacteria are now able to have preferred conditions to take over
-prevention:over-prescribing antibiotic, not finishing course overuse in livestock and farm, HAIs, lack of hygiene, lack of new antibiotics being developed
how to prevent antimicrobial resistance with client teaching
take meds as prescribed, finish course of antibiotics
how to prevent the spread of transmission of infectious micro organism (HAIs)
-disinfectant
-antiseptic
-hand-washing
-immunizations
-education
-evaluate
why do super-infections happen with antimicrobial therapy?
host flora is often destroyed because antibiotics cannot distinguish between them or pathogens
what specific types of infections are considered superinfections and what are the s/s
C Diff, candida
tx of superinfections
vancomycin, metronidazole
s/s of superinfections
diarrhea, painful urination, abdominal vaginal discharges
general client teaching for antibacterial drugs
take full dosage
s/s, nursing actions, and tx expected for patient experiencing an allergic response
-stop talking the drug, rash, hives, anaphylaxis, treat with antihistamines (epinephrine if anaphylaxis)
which drugs are contraindicated for penicillin allergies and why?
-penicillin G, amoxicillin, ampicillin, cephalexin/cefalexin, meropenem, aztreonam
why drugs cause photosensitivity?
tetracycline, trimethoprim-sulfamethoxazole, ciprofloxacin
which antibiotics are the safest during pregnancy?
acylcovir, zidovudine
which antibiotics should be avoided in pregnancy
ganciclovir
which drugs require peak and trough levels
vancomycin and gentamycin
