Exhibits Which of the day 2 lab values would alert the RN that Mary might be experiencing systemic inflammatory response syndrome (SIRS)? (Select All that Apply.)

A. Platelets: Platelets are decreased on Day 2 (81,000/mm3), which is lower than the normal range of 150,000 - 450,000/mm3. Thrombocytopenia can be a sign of systemic inflammation or infection, often seen in SIRS or sepsis. B. Hematocrit: The hematocrit level remains stable (32%) on Day 2 and is within the low-normal range. While low hematocrit may indicate anemia or fluid overload, it is not a specific marker for SIRS. C. Blood glucose: The blood glucose is elevated on Day 2 (138 mg/dL), which is above the normal range of 70-100 mg/dL. Hyperglycemia is a common response to stress, inflammation, or infection, and it can be seen in SIRS or sepsis. D. WBC: The WBC count is elevated on Day 2 (13,000/mm3), which is above the normal range of 4,500 - 10,500/mm3. An elevated WBC count is a classic indicator of an inflammatory or infectious process, which could suggest systemic inflammatory response syndrome (SIRS). E. INR: The INR is elevated (4.4) on Day 2, which is likely due to the patient's use of Warfarin for atrial fibrillation. While an elevated INR increases bleeding risk, it is not directly related to SIRS. F. Potassium: The potassium level (3.9 meq/L) is within the normal range (3.5-5.0 meq/L). There is no indication of a potassium imbalance that would suggest SIRS in this case.
