A nurse assisting with the care of a client who is admitted to the medical-surgical unit. The nurse is reviewing the client's laboratory findings and vital signs. Select the 5 findings that require immediate follow-up.

B. Stool results: A positive hemoccult test indicates gastrointestinal bleeding, likely due to a peptic ulcer. Immediate follow-up is needed to assess for ongoing blood loss and the potential for hemorrhagic complications. C. Heart rate: The tachycardia (118/min) suggests a compensatory response to hypovolemia from gastrointestinal bleeding. This requires prompt intervention to prevent hemodynamic instability. F. Blood pressure: Hypotension (90/50 mm Hg) is concerning for volume depletion due to chronic or active gastrointestinal bleeding. This requires immediate follow-up to prevent shock. G. Hemoglobin and hematocrit: A hemoglobin of 9.1 g/dL and hematocrit of 27% indicate anemia, likely due to gastrointestinal blood loss. Further evaluation and potential blood transfusion may be required. H. Current medications: Ibuprofen use is a major risk factor for peptic ulcer disease and gastrointestinal bleeding. Immediate follow-up is needed to discontinue NSAIDs and initiate appropriate ulcer management. Incorrect: A. Respiratory rate: A rate of 18/min is within the normal range and does not require urgent follow-up. D. Temperature: A temperature of 37.5°C (99.5°F) is slightly elevated but not clinically significant for immediate intervention. E. WBC count: The WBC count is within the normal range, making it less of an immediate concern.
