Which of the following cells is part of the innate immune system?
T lymphocytes
Macrophages
Plasma cells
B lymphocytes
Macrophages are phagocytic cells that act in the innate immune system by engulfing pathogens. Adaptive immune cells such as B and T lymphocytes are not part of the innate response.
What is the first step in effective handwashing?
Scrubbing hands together
Drying hands with a towel
Applying soap to dry hands
Wetting hands under running water
Effective handwashing begins by wetting hands under running water. Soap application and scrubbing follow, with drying as the final step.
Which of the following serves as a physical barrier against pathogens?
T cells
Skin
Cytokines
Antibodies
The skin acts as a primary physical barrier preventing pathogen entry. Antibodies, T cells, and cytokines are components of internal immune defenses.
Coughing or sneezing releases pathogens primarily through which transmission pathway?
Direct inoculation
Vector transmission
Droplet transmission
Foodborne transmission
Coughing and sneezing expel respiratory droplets containing pathogens. Vector and foodborne transmissions involve insects and contaminated food, respectively.
Which vitamin is especially known for supporting the immune system?
Vitamin C
Vitamin K
Vitamin B1
Vitamin E
Vitamin C is well known for its role in supporting various immune functions including antioxidant protection. Other vitamins have different primary roles.
Which characteristic distinguishes adaptive immunity from innate immunity?
Inflammation
Physical barriers
Memory response
Phagocytosis
Adaptive immunity develops immunological memory after exposure to specific antigens, unlike innate immunity which responds the same way each time. Innate immunity relies on physical barriers and phagocytosis.
Which factor is known to weaken immune response when chronically elevated?
Balanced diet
Regular exercise
Adequate sleep
Chronic stress
Chronic stress elevates cortisol levels which can suppress various immune functions. Adequate sleep, balanced diet, and regular exercise generally support the immune system.
For at least how long should hands be scrubbed with soap to effectively remove pathogens?
5 seconds
2 minutes
20 seconds
60 seconds
Health guidelines recommend scrubbing hands with soap for at least 20 seconds to dislodge pathogens. Shorter times are insufficient, while much longer times offer no extra benefit.
Which hygiene practice can help reduce transmission of respiratory infections?
Covering mouth and nose when sneezing
Avoiding dairy products
Eating a nutritious meal
Wearing gloves in public
Covering the mouth and nose when sneezing reduces droplet spread. Nutrition supports immunity but does not directly block respiratory droplets, and gloves or diet changes have limited impact.
How does vaccination primarily boost natural immunity?
Increasing phagocyte count
Stimulating specific antibody and memory cell production
Enhancing skin barrier
Reducing cytokine release
Vaccines introduce antigens that trigger adaptive immune responses, leading to antibody generation and memory cells. Phagocyte numbers and skin barriers are not directly altered by vaccines.
Touching a contaminated doorknob and then your face illustrates which transmission route?
Airborne transmission
Direct droplet transmission
Indirect contact transmission
Vector-borne transmission
Indirect contact transmission occurs when pathogens are transferred via objects (fomites) like doorknobs. Direct droplet and airborne involve respiratory secretions, and vector-borne involves insects.
What is the main role of T-helper cells in the immune response?
Engulfing pathogens
Destroying infected cells directly
Producing antibodies directly
Activating B cells and other immune cells
T-helper cells secrete cytokines that activate B cells and other immune cells. Antibody production is performed by plasma cells, and phagocytosis or direct killing are functions of other cell types.
In a healthcare setting, which practice best reduces hospital-acquired infections?
Wearing cotton uniforms
Using scented lotions
Limiting water intake
Strict hand hygiene protocols
Proper hand hygiene is the most effective measure to prevent cross-contamination in healthcare. Scented lotions, hydration management, and uniform material have little direct impact.
How does moderate exercise typically influence immune function?
Causes permanent immune suppression
Destroys lymph nodes
Enhances circulation of immune cells
Increases pathogen virulence
Moderate exercise improves blood flow, helping circulate immune cells more effectively. Excessive exercise can suppress immunity, but moderate activity is beneficial.
What role do gut microbiota play in immunity?
Supporting immune regulation and pathogen defense
Serving as primary phagocytes
Directly neutralizing viruses in air
Producing red blood cells
Gut microbiota help modulate immune responses and compete with pathogens in the gut. They do not produce red blood cells or directly neutralize airborne viruses.
How does secretory IgA protect mucosal surfaces?
Activating complement cascade in blood
Neutralizing pathogens and preventing adhesion to mucosal cells
Directly lysing bacteria through pore formation
Stimulating phagocytosis in lymph nodes
Secretory IgA binds to pathogens at mucosal surfaces, neutralizing them and blocking their attachment. Complement activation and lysis occur primarily via other immunoglobulins.
What is one mechanism by which sleep deprivation impairs immune function?
Increasing bone marrow activity
Enhancing antibody diversity
Reducing T cell proliferation and cytokine production
Stimulating natural killer cell count
Sleep deprivation leads to decreased T cell proliferation and lower cytokine levels, weakening immune responses. It does not enhance antibody diversity or NK cell counts.
Arrange the following steps of proper soap-based handwashing in the correct order: lather hands with soap, wet hands, rinse with water, scrub for recommended duration, dry hands.
Wet hands, lather hands with soap, scrub for recommended duration, rinse with water, dry hands
Wet hands, rinse with water, lather hands with soap, scrub for recommended duration, dry hands
Wet hands, lather hands with soap, rinse with water, scrub for recommended duration, dry hands
Lather hands with soap, wet hands, scrub for recommended duration, rinse with water, dry hands
The correct sequence is to wet hands first, apply soap, scrub for at least 20 seconds, rinse, then dry. All other orders omit or misplace critical steps.
How does fever contribute to the immune response?
Blocks cytokine release
Directly produces antibodies
Raises body temperature to inhibit pathogen growth and enhance immune efficiency
Cools body to reduce metabolic demand
Fever elevates body temperature, creating an environment less optimal for pathogens and boosting immune cell activity. It does not directly produce antibodies or inhibit cytokines.
Which type of hypersensitivity is mediated by IgE antibodies causing allergic reactions?
Type I hypersensitivity
Type II hypersensitivity
Type IV hypersensitivity
Type III hypersensitivity
Type I hypersensitivity reactions involve IgE binding to mast cells and basophils, leading to allergy symptoms. Other types involve different mechanisms and antibody classes.

Cheat Sheet

  1. Understand the key components of the immune system - Your body's defense army includes organs like bone marrow, thymus, spleen, and lymph nodes plus cells such as lymphocytes and phagocytes. Together, they coordinate to detect and destroy invaders before you even notice. Learning their roles is like getting to know the VIPs at a security checkpoint. Johns Hopkins Medicine: Immune System Overview
  2. Differentiate between innate and adaptive immunity - Innate immunity is your rapid-response force that recognizes common threats immediately but non-specifically. Adaptive immunity takes a little longer to mobilize, crafting tailor-made antibodies and memory cells for long-term protection. Understanding this tag-team approach helps you appreciate how your body learns and improves over time. Cleveland Clinic: The Immune System
  3. Recognize the role of lymphocytes - B cells act as the antibody factories, tagging pathogens for destruction, while T cells serve as both the hit squad and the tactical commanders. Together, they not only eliminate infected cells but also coordinate a clever defense strategy. Mastering their teamwork is like studying the dynamics of a superhero duo. Johns Hopkins Medicine: Immune System Overview
  4. Learn about the complement system - Think of the complement system as a biochemical spotlight and demolition crew, highlighting microbial trespassers and punching holes in their membranes. These proteins boost antibody action and rally phagocytic cells to the scene. It's a powerful backup squad that ensures no invader goes unnoticed. Complement System - Wikipedia
  5. Identify factors influencing immune response effectiveness - Nutrition, exercise, sleep quality, and stress levels all play starring roles in keeping your immune system at peak performance. A balanced diet fuels cellular defenders, while good rest and moderate workouts fine-tune your response time. Recognizing these lifestyle influences turns you into your own health coach. Cleveland Clinic: The Immune System
  6. Master proper handwashing techniques - Effective handwashing is your first line of defense: wet, lather with soap, scrub every nook and cranny for at least 20 seconds, rinse, and dry. This simple ritual can wash away most germs before they hitch a ride into your body. Think of it as a mini car wash for your hands! Hand Washing - Wikipedia
  7. Understand the Ayliffe handwashing technique - This six-step method ensures no part of your hands is left unclean - palm to wrist, between fingers, and under nails. Practicing the Ayliffe technique is like following a treasure map to germ-free skin. Consistency here makes all the difference in infection control. Ayliffe Technique - Wikipedia
  8. Recognize common pathogen transmission pathways - Germs can travel via direct contact, airborne droplets, contaminated food or water, and insect vectors. Visualizing these routes helps you put up effective roadblocks - masks, hygiene, and safe food handling. It's like mapping out enemy supply lines to cut off their advance. Johns Hopkins Medicine: Infection Pathways
  9. Implement hygiene best practices in daily life - Regular handwashing, proper food preparation, and keeping common surfaces clean form a hygiene trifecta against infection. Small habits - like using hand sanitizer or wiping down doorknobs - add up to big protection. Treat cleanliness like a daily superpower routine! Hand Washing Best Practices - Wikipedia
  10. Adopt strategies to boost natural immunity - A rainbow-rich diet, regular physical activity, consistent sleep schedules, and stress management techniques all supercharge your immune forces. Combining these habits is like upgrading your body's software with the latest security patch. Aim for balance, and your defenses will thank you! Boosting Immunity - Cleveland Clinic
