Nursing implications

Nursing assessment

• Assess for infection (vital signs; appearance of wound, sputum, urine, and stool; WBC) at beginning of and throughout therapy.
• Before initiating therapy, obtain a history to determine previous use of and reactions to penicillins or cephalosporins. Persons with a negative history of penicillin sensitivity may still have an allergic response.
• Obtain specimens for culture and sensitivity before initiating therapy. First dose may be given before receiving results.
• Observe patient for signs and symptoms of anaphylaxis (rash, pruritus, laryngeal edema, wheezing). Discontinue the drug and notify health care professional immediately if these symptoms occur. Keep epinephrine, an antihistamine, and resuscitation equipment close by in the event of an anaphylactic reaction.
• Monitor bowel function. Diarrhea, abdominal cramping, fever, and bloody stools should be reported to health care professional promptly as a sign of pseudomembranous colitis. May begin up to several weeks following cessation of therapy.
• Lab Test Considerations: May cause positive results for Coombs' test.
  • Monitor prothrombin time and assess patient for bleeding (guaiac stools; check for hematuria, bleeding gums, ecchymosis) daily in high-risk patients; may cause hypoprothrombinemia.
  • May cause ↑ serum AST, ALT, alkaline phosphatase, bilirubin, LDH, BUN, and creatinine.
  • May rarely cause leukopenia, neutropenia, agranulocytosis, thrombocytopenia, and eosinophilia.

Potential Nursing Diagnoses

Implementation

• Do not confuse cefotetan with cefazolin, cefoxitin, ceftazidime, or ceftriaxone.
• Intramuscular: Reconstitute IM doses with sterile or bacteriostatic water for injection or 0.9% NaCl for injection. May be diluted with lidocaine to minimize injection discomfort.
  • Inject deep into a well-developed muscle mass; massage well.

• Intravenous Administration

• pH: 4.5–6.5.
• Intravenous: Change sites every 48–72 hr to prevent phlebitis. Monitor site frequently for thrombophlebitis (pain, redness, swelling).
  • If aminoglycosides are administered concurrently, administer in separate sites if possible, at least 1 hr apart. If second site is unavailable, flush line between medications.
• Diluent: Reconstitute each gram with at least 10 mL of sterile water for injection. Do not use preparations containing benzyl alcohol for neonates. Concentration: ≤10 mg/mL.
• Rate: Administer slowly over 3–5 min.
• Intermittent Infusion: Diluent: Reconstituted solution may be further diluted in 50–100 mL of D5W or 0.9% NaCl. Solution is stable for 24 hr at room temperature or 96 hr if refrigerated. Concentration: ≤200 mg/mL.
• Rate: Administer over 30–60 min.

Patient/Family Teaching

• Advise patient to report signs of superinfection (furry overgrowth on the tongue, vaginal itching or discharge, loose or foul-smelling stools) and allergy.
• Caution patients that concurrent use of alcohol and cefotetan may cause a disulfiram-like reaction (abdominal cramps, nausea, vomiting, headache, hypotension, palpitations, dyspnea, tachycardia, sweating, flushing). Alcohol and alcohol-containing medications should be avoided during and for several days after therapy.
• Instruct patient to notify health care professional if fever and diarrhea develop, especially if stool contains blood, pus, or mucus. Advise patient not to treat diarrhea without consulting health care professional.

Evaluation/Desired Outcomes

• Resolution of signs and symptoms of infection. Length of time for complete resolution depends on the organism and site of infection.
• Decreased incidence of infection when used for prophylaxis.
