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)]

Respiratory rate of 26 breaths/minute.

Heart rate of 112 beats/minute.

Temperature of 96.1° F (35.6°C).

White blood count of 14,000/mm3 (14 x 109/L).

Hemoglobin of 12.8 gram/dL (7.94 mmol/L).

Answer and Explanation

Correct Answer : A,B,C,D

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 (<96.8°F/36°C) is a SIRS criterion and may indicate severe sepsis or systemic inflammatory response. While fever is a common response, low temperature suggests immune system dysfunction. Hypothermia in sepsis is linked to poor prognosis and increased mortality risk.
D. White blood count of 14,000/mm³ (14 x 10⁹/L). A WBC >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.

Correct Answer is B

Explanation

A. Turn off the pacemaker. Turning off the pacemaker is not appropriate because the client has a third-degree heart block, which means their heart is not conducting impulses properly. Disabling the pacemaker could lead to severe bradycardia or asystole. The goal is to troubleshoot the issue rather than stopping pacing altogether.
B. Check the sensitivity control. Loss of sensing means the pacemaker is not detecting the client's intrinsic heart activity, which can lead to inappropriate pacing or failure to respond to the heart’s natural rhythm. Adjusting the sensitivity setting ensures that the pacemaker can recognize the client's heartbeats and pace appropriately. This is the first step in troubleshooting pacemaker malfunctions related to sensing issues.
C. Increase the milliamps (mA). Increasing the milliamps (mA) is used when there is failure to capture, meaning the pacemaker is delivering impulses but the heart is not responding. Since the problem here is failure to sense, adjusting the sensitivity setting is the correct first action.
D. Position the client on the left side. Repositioning the client is sometimes recommended for displacement of a transvenous pacemaker lead, but in this case, the issue is sensing failure, not lead displacement. Checking and adjusting the pacemaker settings is a more appropriate first step before considering repositioning.

A. Perform the Allen test. B. Elevate the client's right arm. C. Flush the line with heparinized saline. D. Notify the healthcare provider.

Correct Answer is D

Explanation

A. Perform the Allen test. The Allen test is performed before inserting a radial arterial line to assess ulnar artery patency and ensure adequate collateral circulation. Since the arterial line is already placed and the client is showing signs of compromised circulation (pallor, paresthesia, and slow capillary refill), immediate intervention is required rather than further pre-insertion testing.
B. Elevate the client's right arm. Elevating the arm does not directly resolve arterial compromise and may further reduce perfusion by impairing arterial blood flow. The priority is to assess and address potential ischemia caused by arterial line complications.
C. Flush the line with heparinized saline. Flushing an arterial line is appropriate for maintaining patency, but in this case, it may worsen ischemia if the catheter is causing an obstruction or arterial spasm. Additionally, flushing should never be done forcefully due to the risk of embolization.
D. Notify the healthcare provider. The pallor, paresthesia, and delayed capillary refill suggest arterial insufficiency, possible thrombosis, or arterial spasm, which can lead to tissue ischemia and necrosis if not addressed promptly. The healthcare provider should be notified immediately to assess the need for interventions such as removal of the arterial line, vascular assessment, or anticoagulation therapy.
