Immune System Overview Quiz

Based on the diagram, which cells are involved in the innate immune response?

• Mast cells, phagocytes, dendritic cells, NK cells, epithelial barriers

• B lymphocytes, T lymphocytes, plasma cells

• Red blood cells, platelets, neurons

• Effector T cells, antibodies, plasma cells

Strategically, why is it important for the immune system to have both innate and adaptive components?

• The innate system provides immediate defense, while the adaptive system offers specific and long-lasting protection.

• Both systems only work in plants.

• The adaptive system is only active during childhood.

• The innate system is responsible for producing antibodies.

Which of the following best describes the innate immune system?

• It is inherited and acts as the first line of defense against pathogens.

• It develops after exposure to pathogens and has immunologic memory.

• It only responds to viruses and not bacteria.

• It requires prior antigen exposure for activation.

Why does the innate immune system respond the same way to a pathogen, regardless of previous encounters?

• Because it lacks immunologic memory.

• Because it adapts and improves with each exposure.

• Because it only targets specific pathogens.

• Because it is slower than the adaptive immune system.

What does the image of the fish with "Short-term memory loss...??" humorously represent in the context of innate immunity?

• The innate immune system does not remember previous encounters with pathogens.

• The innate immune system has a long-term memory.

• The innate immune system only works in fish.

• The innate immune system is slow to respond.

Which cells produce nitric oxide (NO) that destroys microbes and cytokines that activate the adaptive immune system?

• Basophils and mast cells

• Neutrophils and eosinophils

• Monocytes and macrophages

• Platelets and erythrocytes

Which class of drugs used for the treatment of hypertension and heart failure can precipitate angioedema in about 0.2% of patients?

• Beta-blockers

• Calcium channel blockers

• Angiotensin-converting enzyme (ACE) inhibitors

• Diuretics

Which drugs are typically used to treat mast cell–mediated angioedema?

• Antivirals and antibiotics

• Epinephrine, antihistamines, and glucocorticoids

• ACE inhibitors and diuretics

• Statins and beta-blockers

Why might tracheostomy be extremely difficult or impossible in patients with angioedema?

• Because of massive airway edema

• Because of low blood pressure

• Because of high fever

• Because of excessive bleeding

Which anesthetic techniques are well tolerated in patients with angioedema?

• Regional anesthetic techniques and intramuscular injections

• General anesthesia only

• Inhalational anesthesia only

• No anesthesia is tolerated
