Nursing care for Cefazolin (Ancef) focuses on

IV site management, allergy screening, and superinfection monitoring

IV site vigilance

given IM or IV (never oral). Assess the IV site regularly — if the patient reports pain, burning, or swelling, stop the infusion and change the site immediately, as these are signs of thrombophlebitis (vein inflammation), the signature IV complication of 1st gen cephalosporins.

Allergy screening

Before the first dose, assess for penicillin cross-sensitivity — patients with severe penicillin allergies may react to cephalosporins too. Verify the exact allergy history (rash vs. anaphylaxis) before administering.

Superinfection monitoring

Watch for and report severe diarrhea — a sign of C. difficile-associated diarrhea (CDAD), which can occur with any cell wall inhibitor that disrupts normal gut flora.

Patient education

Report any burning or pain at the IV site right away

Report severe or watery diarrhea to the provider

The highest-yield points for Cefazolin are

stopping the IV at the first sign of site pain/swelling (thrombophlebitis) and the penicillin cross-sensitivity check
