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? (Click on the exhibit tabs for additional information about the client. There are three tabs that contain separate categories of data.)

Allergies: The client has a documented allergy to penicillin, and cefazolin is a first-generation cephalosporin. Cephalosporins have a similar beta-lactam structure to penicillins, and there is a potential risk of cross-reactivity. Administering cefazolin without provider clearance could result in a severe allergic reaction or anaphylaxis. Temperature: Although the client's temperature is elevated at 39.3° C (102.8° F), this is an expected finding in pneumonia and does not need to be reported before antibiotic administration. In fact, treating the infection may help reduce the fever. Chest x-ray: The chest x-ray showing left lower lobe density is consistent with a diagnosis of pneumonia and supports the need for antibiotic treatment. This finding confirms the infection in the lungs and guides the choice of antibiotic therapy. It is not a reason to withhold the prescribed medication but rather a justification for it. WBC count: The client’s WBC count is elevated at 16,000/mm³, which is typical in bacterial infections like pneumonia. It reflects the body's immune response and further supports the need for antibiotics rather than delaying them.
