Extended Spectrum Penicillins
piperacillin indications
Gonorrhea, peritonitis, UTI, pneumonia & resp infections, septicemia, meningitis
piperacillin SE
rash
hard on kidney’s bc it is a board spectrum abx
affects platelet function
piperacillin nursing considerations
Always given with a beta lactamase inhibitor (Zosyn)
Very good for pseudomonal infections (get through water & causes res distress, HA, pus fill sacs on skin, disorientation)
Broadest spectrum (pull peak & trough)
what class is cephalosporin
cephalosporins
cephalosporins (general & all the generations) MOA
Disrupt the synthesis of the cell wall (active autolysis)

cephalosporin SE
Mild diarrhea
Abdominal cramps
Rash
Pruritis
Redness
edema
cephalosporin nursing considerations
safe for pregnancy (category B)
poor oral absorption
low toxicity
avoid if PCN anaphylaxis
if you have anaphylaxis to PCN, what other drug class should be avoided
cephalosporins
what class are Cefazolin and Cephalexin
1st generation cephalosporins

Redness
edema
Cefazolin and Cephalexin nursing considerations
Cefazolin is IV only
Cefazolin is common for surgical prophylaxis
Works well for gram +
Do not work for CNS infections
what class are Cefuroxime & Cefotetan
2nd generation cephalosporins
Cefuroxime & Cefotetan indications
STDs, peritonitis, UTI, pneumonia & resp infections, septicemia,
Cefotetan for abdominal infection
Cefuroxime & Cefotetan SE
Mild diarrhea
Abdominal cramps
Rash
Pruritis
Redness
edema
Cefuroxime & Cefotetan nursing considerations
Better for gram – but works for both
Cefuroxime does not kill anerobic bacteria
Do not work for CNS infections
what class are Ceftriaxone, Ceftazidine and Cefotaxine
3rd generation cephalosporins
Ceftriaxone, Ceftazidine and Cefotaxine indications

Rash
Pruritis
Redness
edema
Ceftriaxone, Ceftazidine and Cefotaxine nursing considerations
most potent against gram -
only given IV/IM
Ceftriaxone nursing considerations
extremely long acting (1x/d)
can cross blood brain barrier
do not give to paitents w/ liver failue
ceftazidime nursing considerations
works well for pseudomonas
