A female client admitted with possible pneumonia and systemic inflammatory response syndrome (SIRS) is manifesting low oxygen saturation rates. Which additional finding(s) associated with SIRS should the nurse report to the health care provider (HCP)? Select all that apply. Reference Range White Blood Cell [5,000 to 10,000/mm3 (5 to 10 10/L)] Hemoglobin [12 to 16 g/dL (7.45 to 9.93 mmol/L)]
Explanation & Rationale
A. Respiratory rate of 26 breaths/minute. A respiratory rate ≥22 breaths/minute meets the SIRS criteria and indicates systemic inflammation or respiratory distress. In pneumonia, increased breathing effort may result from hypoxia or infection-related metabolic demands. Persistent tachypnea suggests worsening sepsis and requires urgent intervention. B. Heart rate of 112 beats/minute. A heart rate ≥90 beats/minute is a SIRS criterion, often caused by infection, hypoxia, or systemic inflammation. In pneumonia, tachycardia may result from fever, pain, or compensatory mechanisms due to decreased oxygenation. An elevated heart rate in sepsis may indicate progressing hemodynamic instability. C. Temperature of 96.1° F (35.6°C). Hypothermia (12,000/mm³ or <4,000/mm³ meets SIRS criteria and indicates infection-related immune activation. Elevated WBCs suggest an active inflammatory response to pneumonia. A rising WBC count may indicate worsening infection or ineffective immune control. E. Hemoglobin of 12.8 gram/dL (7.94 mmol/L). Hemoglobin levels within the normal range (12-16 g/dL) do not indicate SIRS or sepsis progression. While anemia can develop in chronic illness or bleeding, this value does not contribute to SIRS classification. Monitoring oxygenation and perfusion is more relevant in pneumonia cases.
