NURSING CONSIDERATIONS
Assess:

• 
Sensitivity to penicillin, other cephalosporins

 
Nephrotoxicity:
increased BUN, creatinine; urine output: if decreasing, notify prescriber

• 
Blood studies: AST, ALT, CBC, Hct, bilirubin, LDH, alk phos, Coombs’ test monthly if patient is on long-term therapy

• 
Electrolytes: potassium, sodium, chloride monthly if patient is on long-term therapy

• 
Pseudomembranous colitis:
bowel pattern daily; if severe diarrhea occurs, product should be discontinued

• 
IV site for extravasation, phlebitis

 
Anaphylaxis:
rash, urticaria, pruritus, chills, fever, joint pain, angioedema; may occur a few days after therapy begins

• 
Bleeding: ecchymosis, bleeding gums, hematuria, stool guaiac

 
Overgrowth of infection:
perineal itching, fever, malaise, redness, pain, swelling, drainage, rash, diarrhea, change in cough, sputum

Evaluate:

• 
Therapeutic response: decreased symptoms of infection; negative C&S

Teach patient/family:

• 
If diabetic, to check blood glucose

 
To report sore throat, bruising, bleeding, joint pain, may indicate
blood dyscrasias (rare);
diarrhea with mucus, blood, may indicate
pseudomembranous colitis

• 
That cefditoren can be taken with oral contraceptives

TREATMENT OF ANAPHYLAXIS:

EPINEPHrine, antihistamines; resuscitate if needed
