Inflammation & Healing Quiz

What is inflammation?

• A specific immune response only against bacteria

• A defensive, nonspecific reaction to neutralize, control, or eliminate an offending agent and prepare the site for repair

• A process of tissue regeneration only

• A hypersensitivity reaction

Which are the five cardinal signs of inflammation?

• Redness, Heat, Swelling, Pain, Loss of function

• Cough, Fever, Redness, Fatigue, Nausea

• Swelling, Jaundice, Cyanosis, Weakness, Pain

• Redness, Tachycardia, Swelling, Shock, Pain

Which mediator causes rapid vasodilation in early inflammation?

• Bradykinin

• Prostaglandin

• Histamine

• Serotonin

What is the role of prostaglandins in inflammation?

• Cause clot formation

• Increase capillary permeability and pain

• Activate complement system

• Stimulate antibody production

What systemic signs often occur in acute inflammation?

• Fever, leukocytosis, malaise, anorexia, weakness

• Tachycardia, hypertension, diaphoresis, fatigue

• Rash, itching, dyspnea, wheezing

• Pallor, cyanosis, hypothermia, cough

Differentiate acute vs. chronic inflammation.

• Acute = long-lasting, fibrosis; Chronic = rapid, short (500/µL

• CD4 6 hours

• No restrictions on sun exposure

What is the primary function of neutrophils in inflammation?

• To produce antibodies

• To phagocytize pathogens and debris

• To release histamine

• To promote tissue repair

Which cytokine is primarily responsible for inducing fever during inflammation?

• Interleukin-1 (IL-1)

• Interferon-gamma (IFN-γ)

• Interleukin-6 (IL-6)

• Tumor necrosis factor-alpha (TNF-α)

What is the significance of increased vascular permeability in inflammation?

• It allows for the migration of leukocytes to the site of injury

• It prevents blood loss from damaged vessels

• It reduces swelling and pain

• It promotes the formation of scar tissue
