A nurse is reviewing the client's electronic medical record. Exhibits Which of the following findings require follow up? Select all that apply.

A. Blood pressure – The client's blood pressure of 114/56 mm Hg is within an acceptable range and does not indicate hypotension or hypertension. B. Temperature – A temperature of 38.6°C (101.5°F) is indicative of fever, which is concerning in a client undergoing chemotherapy due to their increased risk of infection (febrile neutropenia). Prompt evaluation and intervention are necessary to prevent sepsis. C. Potassium level – The client's potassium level of 3.6 mEq/L is within the normal range (3.5 to 5 mEq/L) and does not require immediate intervention. D. WBC count – The client's WBC count has decreased to 3,800/mm³, which is below the normal range (5,000 to 10,000/mm³), indicating leukopenia. This places the client at a higher risk for infection, requiring close monitoring and potential interventions. E. Breath sounds – The presence of crackles at the lung bases suggests possible pulmonary complications, such as fluid overload, infection (e.g., pneumonia), or early signs of acute respiratory distress syndrome (ARDS). This finding warrants further assessment and intervention.
