SIRS

Question 1

What does SIRS stand for?

Answer 1

Systemic Inflammatory Response Syndrome.

Question 2

What is SIRS?

Answer 2

A clinical condition characterized by an exaggerated inflammatory response to a variety of stimuli.

Question 3

What can SIRS lead to?

Answer 3

SIRS → Sepsis → MODS (Multiple Organ Dysfunction Syndrome).

Question 4

What are common causes (stimuli) of SIRS?

Answer 4

Infection, trauma, pancreatitis, burns, crush injuries, surgery, abscesses, ischemic/necrotic tissue, microbial invasion, endotoxin release, global/regional perfusion deficits.

Question 5

What’s the main difference between SIRS and Sepsis?

Answer 5

Sepsis: Must have a confirmed or presumed infection.
SIRS: Does not require infection.

Question 6

Can SIRS exist without infection?

Answer 6

Yes, SIRS can occur due to noninfectious causes like trauma, burns, or pancreatitis.

Question 7

Why is prompt attention important in SIRS?

Answer 7

To identify and treat the underlying cause and prevent progression to sepsis or MODS.

Question 8

Name examples of mechanical tissue trauma triggers for SIRS.

Answer 8

Burns, crush injuries, surgery.

Question 9

Name examples of abscess formation triggers for SIRS.

Answer 9

Intraabdominal abscesses, abscesses in extremities (often from MRSA).

Question 10

Name examples of ischemic or necrotic tissue triggers for SIRS.

Answer 10

Pancreatitis, vascular disease, myocardial infarction (MI).

Question 11

Name examples of microbial invasion triggers for SIRS.

Answer 11

Bacteria, viruses, fungi, parasites.

Question 12

What type of bacteria releases endotoxins that can trigger SIRS?

Answer 12

Both gram-negative and gram-positive bacteria.

Question 13

What are global perfusion deficit causes of SIRS?

Answer 13

Post-cardiac resuscitation, shock.

Question 14

What are regional perfusion deficit causes of SIRS?

Answer 14

Distal perfusion deficits (e.g., fingers).

Question 15

What are the diagnostic criteria for SIRS?

Answer 15

Must meet 2 or more of the following:
• Tachycardia >90 bpm
• Tachypnea >20/min
• Hyperthermia (>101°F) or Hypothermia (<96.8°F)
• Hypotension
• Flushing, Pallor, or Mottling
• WBC >12,000/mm³ or <4,000/mm³ or >10% immature (band) forms.

Question 16

What does tachycardia indicate in SIRS?

Answer 16

Increased systemic response to inflammation or infection.

Question 17

What does tachypnea indicate in SIRS?

Answer 17

Early sign of metabolic acidosis and systemic inflammation.

Question 18

What are abnormal WBC findings in SIRS?

Answer 18

WBC >12,000 or <4,000 or >10% immature (bands).

Question 19

What is the first diagnostic study often performed to find the cause of SIRS?

Answer 19

X-ray — least invasive (e.g., to check for pneumonia).

Question 20

What lab values may be elevated or decreased in SIRS?

Answer 20

Elevated or decreased WBC, elevated creatinine (decreased kidney function), electrolyte imbalances.

Question 21

What does elevated lactate indicate in SIRS?

Answer 21

Tissue hypoperfusion and anaerobic metabolism.

Question 22

What labs assess clotting function in SIRS?

Answer 22

PT/INR and PTT.

Question 23

What imaging can be used if cause not identified by X-ray?

Answer 23

CT scan — to find deeper or internal causes.

Question 24

What is the main treatment goal in SIRS?

Answer 24

Identify and treat the underlying cause.

Question 25

What is the purpose of fluid resuscitation in SIRS?

Answer 25

Maintain BP and tissue perfusion.

Question 26

Is there a specific fluid formula for SIRS?

Answer 26

No specific formula — treat based on patient response.

Question 27

When are vasopressors used in SIRS?

Answer 27

To treat hypotension when fluids are not effective.

Question 28

Why is oxygen important in SIRS treatment?

Answer 28

To correct hypoxia, especially in respiratory distress.

Question 29

When are corticosteroids used in SIRS?

Answer 29

In patients with septic shock to reduce inflammation.

Question 30

Why is timely intervention critical in SIRS?

Answer 30

Early recognition and treatment improve outcomes and prevent sepsis or MODS.

Question 31

Who usually identifies SIRS first?

Answer 31

Nurses — because they spend the most time with the patient and monitor subtle changes.

Question 32

What vital signs should nurses monitor closely in SIRS?

Answer 32

Temperature, HR, RR, BP, O₂ saturation.

Question 33

What patient signs indicate progression toward sepsis or MODS?

Answer 33

Infection signs, organ dysfunction, and altered mental status.

Question 34

Why is urinary output important to monitor?

Answer 34

Indicates kidney perfusion and overall tissue perfusion.

Question 35

What is a key nursing intervention to prevent secondary infections?

Answer 35

Strict hand hygiene.

Question 36

What are examples of secondary infections to prevent?

Answer 36

CAUTIs (catheter-associated UTIs), central line infections.

Question 37

What education should nurses provide to patients?

Answer 37

Importance of infection prevention, hand hygiene, early reporting of symptoms.

Question 38

What’s the overall nursing goal in managing SIRS?

Answer 38

Prevent progression to sepsis or MODS through early detection and intervention.
