Exhibits A nurse is collecting data from a client who has pneumonia and a prescription for cefazolin. Which of the following findings should the nurse report to the provider prior to administering the initial dose? (Cliick on the exhibit tabs for additional information about t three tabs that contain separate categories of data.)

Rationale: • Temperature: An elevated temperature of 39.3° C is consistent with an active infection like pneumonia. This finding supports the need for antibiotic treatment and does not delay administration unless linked to an adverse drug reaction. • WBC count: A WBC count of 16,000/mm³ indicates leukocytosis, which is expected in bacterial pneumonia. It confirms infection and the need for antibiotics, not a reason to withhold cefazolin. • Allergies: The client has a documented allergy to penicillin, which is critical because cefazolin is a cephalosporin. Cephalosporins share a similar beta-lactam structure and can cross-react in clients with penicillin allergies, increasing the risk of anaphylaxis. Reporting this ensures safe prescribing and prevents a life-threatening hypersensitivity reaction. • Chest x-ray: The left lower lobe density confirms pneumonia. This imaging supports the clinical decision to administer antibiotics and does not warrant withholding the prescribed medication.
