Nursing Implications

Assessment & Drug Effects

  • Lab tests: Perform culture and sensitivity tests prior to and at regular intervals throughout therapy. Therapy may be initiated pending test results. Evaluate renal, hepatic, and hematopoietic systems at regular intervals during prolonged therapy. Patients with creatinine clearance of less than 10 mL/min (normal: 105–130 mL/min) will not attain therapeutic urine levels.
  • Inquire carefully concerning patient's previous exposure and sensitivity to penicillin and cephalosporins and other allergic reactions of any kind before treatment is initiated.
  • Note that drug-induced nausea, unpleasant aftertaste and smell, dry mouth, and furry tongue may be so objectionable as to necessitate drug withdrawal. Report to physician if symptoms persist.
  • Monitor I&O rates and pattern: Check with physician regarding optimum daily fluid intake. Report any change in quality or quantity of urine or in I&O ratio.
  • Observe patient for signs of electrolyte imbalance. Each 1 g of drug contains approximately 1 mEq of sodium.

Patient & Family Education

  • Take this medication with a full glass of water on an empty stomach.
  • Take medication around the clock, do not miss any doses, and continue taking medication until it is all gone unless otherwise directed by physician.
