Blood contains which three major types of cells that float in the liquid plasma?
Correct Answer
D. All of the above
Explanation
The correct answer is "all of the above" because blood contains all three major types of cells - red blood cells (RBCs), white blood cells (WBCs), and platelets. These cells are suspended in the liquid plasma of the blood. RBCs are responsible for carrying oxygen to the body's tissues, WBCs play a role in the immune system and fighting off infections, and platelets help in blood clotting to prevent excessive bleeding.
2.
_______ make up 20-25% of the total WBC count and are very important because they provide immunologic memory.
Correct Answer
A. LympHocytes
Explanation
Lymphocytes make up 20-25% of the total WBC count and are very important because they provide immunologic memory. They play a crucial role in the adaptive immune response, recognizing and remembering specific pathogens. This allows the immune system to respond more effectively upon subsequent encounters with the same pathogen. Lymphocytes include B cells, T cells, and natural killer cells, each with their own specialized functions in immune defense.
3.
Along with neutrophils, these also serve as the first line of defense against infection and perform the same functions as monocytes
Correct Answer
B. MacropHages
Explanation
Macrophages serve as the first line of defense against infection, just like neutrophils. They are a type of white blood cell that engulfs and destroys pathogens, dead cells, and other foreign substances in the body. Macrophages also play a role in initiating and regulating immune responses. They are similar to monocytes in terms of their functions, as both are involved in phagocytosis and antigen presentation. Therefore, macrophages are the correct answer as they align with the given explanation.
4.
_______ make up 60-70% of WBCs and are part of the organism's first line of defense against infection.
Correct Answer
D. NeutropHils
Explanation
Neutrophils make up 60-70% of WBCs and are part of the organism's first line of defense against infection. They are phagocytic cells that are able to engulf and destroy bacteria and other pathogens. Neutrophils are typically the first immune cells to arrive at the site of infection and play a crucial role in the inflammatory response. They release enzymes and chemicals to kill the invading pathogens and recruit other immune cells to the site of infection.
5.
This WBC is found in very small numbers in circulating blood and nasal secretions
Correct Answer
A. BasopHils
Explanation
Basophils are a type of white blood cell (WBC) that are found in very small numbers in circulating blood and nasal secretions. They play a role in the immune response by releasing chemicals such as histamine, which are involved in allergic reactions and inflammation. Basophils are also involved in defense against parasites. Neutrophils, eosinophils, and B-lymphocytes are other types of WBCs, but they are not specifically associated with being found in small numbers in circulating blood and nasal secretions.
6.
_________ specializes in presenting parts of these organisms to other cells in the immune system, such as t-cells, and are thus known as "antigen presenting cells".
Correct Answer
C. Monocytes
Explanation
Monocytes specialize in presenting parts of organisms to other cells in the immune system, such as T-cells, and are thus known as "antigen presenting cells". This means that monocytes play a crucial role in the immune response by presenting antigens to T-cells, which then activate the immune system to fight against pathogens.
7.

Correct Answer
A. Option 1
8.
These lymphocytes mature in the thymus and are responsible for cell-mediated immunity
Correct Answer
A. T-lympHocytes
Explanation
T-lymphocytes, also known as T-cells, are a type of lymphocyte that mature in the thymus. They play a crucial role in cell-mediated immunity, which involves the activation of immune cells to directly attack and destroy infected or cancerous cells. T-lymphocytes recognize specific antigens on the surface of these abnormal cells and initiate an immune response to eliminate them. This response can include the release of chemicals called cytokines, which attract other immune cells to the site of infection or inflammation. Therefore, T-lymphocytes are responsible for coordinating and regulating the body's immune response against pathogens and abnormal cells.
9.
_______ mature in the bone marrow and are found in the blood stream
Correct Answer
A. B-lympHocytes
Explanation
B-lymphocytes mature in the bone marrow and are found in the bloodstream. These cells are a type of white blood cell that play a crucial role in the immune response. They are responsible for producing antibodies, which help to identify and neutralize foreign substances in the body. B-lymphocytes are an important component of the adaptive immune system and help to protect against infections and diseases.
10.
_______ make up 1-3% of WBCs and are increased in allergic disorders and parasite infections
Correct Answer
B. EosinopHils
Explanation
Eosinophils make up 1-3% of white blood cells (WBCs) and are increased in allergic disorders and parasite infections. Eosinophils are a type of granulocyte that play a role in immune responses against parasites and in allergic reactions. They release toxic substances to kill parasites and are involved in the inflammation response during allergies. Therefore, an increase in eosinophils can indicate the presence of these conditions.
11.
When an allergen binds to and cross-links the IgE, the ____________ releases chemical mediators from its granules
Correct Answer
D. Mast cells
Explanation
When an allergen binds to and cross-links the IgE, mast cells release chemical mediators from their granules. Mast cells are a type of immune cell found in tissues throughout the body, especially in areas prone to allergic reactions such as the skin, lungs, and digestive tract. When activated by an allergen, mast cells release substances like histamines, prostaglandins, and leukotrienes, which trigger an inflammatory response. This response leads to the symptoms associated with allergies, such as itching, sneezing, and swelling. Dendritic cells and macrophages are also involved in the immune response but do not release the same chemical mediators as mast cells.
12.
The _______ immune system is the system that is always ready and does not depend upon specific recognition
Correct Answer
A. Innate
Explanation
The correct answer is "innate". The innate immune system is always ready and does not depend on specific recognition. It is the first line of defense against pathogens and works through general mechanisms such as physical barriers, inflammation, and phagocytosis. Unlike the adaptive immune system, which requires time to recognize and respond to specific pathogens, the innate immune system provides immediate protection.
13.
__________ is the process of engulfing bacteria and taking it inside a macrophage for destruction and breakdown
Correct Answer
C. pHagocytosis
Explanation
Phagocytosis is the process by which a macrophage engulfs bacteria and brings it inside for destruction and breakdown. This process involves the macrophage extending its membrane around the bacteria, forming a phagosome. The phagosome then fuses with lysosomes, forming a phagolysosome, where the bacteria are destroyed by enzymes and other substances. Phagocytosis is an important mechanism of the immune system to eliminate pathogens and foreign particles.
14.
How long do macrophages stay in the blood stream before patrolling in the body's tissues?
Correct Answer
D. 3 days
Explanation
Macrophages are immune cells that play a crucial role in the body's defense system. They are initially produced in the bone marrow and released into the bloodstream as monocytes. From the bloodstream, they migrate to various tissues where they differentiate into mature macrophages. Once in the tissues, macrophages perform their functions, such as engulfing and destroying pathogens. The given answer, 3 days, suggests that macrophages spend approximately three days in the bloodstream before patrolling the body's tissues. This time allows for the transportation of monocytes to different areas, where they can mature into macrophages and carry out their immune functions.
15.
The _____ system is made up of a number of proteins that circulate in the body and are harmless until they are activated and attach to bacteria. Once they attach they either punch holes in the cell membrane or make it easier for the phagocytic cells to engulf and destroy the sell
Correct Answer
B. Complement
Explanation
The complement system is a group of proteins that circulate in the body and remain harmless until they are activated and attach to bacteria. Once attached, they can either create holes in the cell membrane or facilitate the engulfment and destruction of the bacteria by phagocytic cells.
16.
Once a T-Cell becomes excited and multiplies, it goes through a process called _______. This process produces new cells that are exact copies of the original cell
Correct Answer
B. Clonal expansion
Explanation
Clonal expansion is the correct answer because once a T-Cell becomes excited and multiplies, it goes through a process called clonal expansion. This process involves the rapid proliferation of the T-Cell, resulting in the production of new cells that are exact copies of the original cell. These new cells play a crucial role in the immune response by recognizing and attacking specific antigens. Phagocytosis is the process by which cells engulf and digest foreign particles, while the complement system is a group of proteins that work together to enhance the immune response.
17.
How many proteins is a T-Cell designed to recognize?
Correct Answer
A. One
Explanation
A T-Cell is designed to recognize one specific protein. T-Cells are a type of white blood cell that play a crucial role in the immune system by identifying and attacking foreign substances in the body. Each T-Cell has a unique receptor on its surface that is capable of recognizing a specific protein, known as an antigen. This recognition allows the T-Cell to initiate an immune response against the antigen, helping to eliminate the threat. Therefore, a T-Cell is designed to recognize only one protein.
18.
Which type of T-Cells kill abnormal host cells?
Correct Answer
C. Killer or cytotoxic t-cells
Explanation
Killer or cytotoxic T-cells are a type of T-cells that are responsible for killing abnormal host cells. These cells play a crucial role in immune responses by identifying and destroying cells that have been infected with viruses or have become cancerous. They do this by releasing toxic substances that induce cell death in the target cells. Killer or cytotoxic T-cells are an essential component of the immune system's defense against infections and tumors.
19.
Which type of t-cell directs the immune response by sending out various signals which help other cells get excited about defending the body?
Correct Answer
A. Helper t-cells
Explanation
Helper T-cells, also known as CD4+ T-cells, play a crucial role in the immune response by releasing signals called cytokines. These signals help activate and coordinate other immune cells, such as B-cells and cytotoxic T-cells, to mount a defense against pathogens. Helper T-cells are responsible for enhancing the immune response and assisting in the production of antibodies, making them vital in the body's defense against infections.
20.
Which immune system is our body's first line of defense against infection?
Correct Answer
A. Innate or nonspecific
Explanation
The innate or nonspecific immune system is our body's first line of defense against infection. It is called nonspecific because it provides a general defense mechanism against a wide range of pathogens, without targeting specific antigens. This immune system includes physical barriers like the skin and mucous membranes, as well as cellular components like phagocytes and natural killer cells. These components work together to quickly recognize and eliminate foreign invaders, providing immediate protection against infections. The adaptive or specific immune system, on the other hand, is a more targeted response that develops over time and specifically targets antigens that have been encountered before.
21.

Correct Answer
A. IgG
Explanation
IgG is the antibody found in the highest quantities in the bloodstream. It is the most abundant antibody in the human body and plays a crucial role in providing long-term immunity against pathogens. IgG is able to cross the placenta, providing passive immunity to newborns, and it also activates complement proteins to enhance the immune response.
24.
Which antibody is the allergic antibody?
Correct Answer
D. IgE
Explanation
IgE is the allergic antibody because it is primarily involved in allergic reactions. When an allergen enters the body, IgE antibodies are produced and bind to mast cells and basophils. Upon re-exposure to the allergen, these IgE antibodies trigger the release of inflammatory mediators, such as histamine, leading to allergic symptoms such as itching, swelling, and difficulty breathing. IgG, IgA, and IgM are involved in different immune responses but are not specifically associated with allergic reactions.
25.

Explanation
Anaphylaxis is defined as the triggered appearance of one or more associated systemic signs and symptoms that are usually responsive to epinephrine. Anaphylaxis is a severe allergic reaction that occurs rapidly and can be life-threatening. It is characterized by symptoms such as difficulty breathing, swelling of the throat or tongue, hives, low blood pressure, and gastrointestinal symptoms. Prompt administration of epinephrine is essential in the treatment of anaphylaxis.
26.
______ are a subset of antigens that bind to circulation IgE antibodies and cause an allergic reaction
Correct Answer
C. Allergens
Explanation
Allergens are a subset of antigens that bind to circulation IgE antibodies and cause an allergic reaction. Antigens are substances that can trigger an immune response in the body, and allergens specifically trigger an allergic response. When an allergen enters the body, it binds to IgE antibodies, which then release histamines. Histamines are responsible for the symptoms of an allergic reaction, such as itching, sneezing, and swelling. Therefore, allergens are the correct answer as they specifically refer to substances that cause allergies by binding to IgE antibodies.
27.
Which of the following is not considered a sign or symptom of anaphylaxis
Correct Answer
B. Gi upset
Explanation
GI upset is not considered a sign or symptom of anaphylaxis. Anaphylaxis is a severe allergic reaction that can cause symptoms such as difficulty breathing, hives, swelling, low blood pressure, and rapid heartbeat. GI upset, such as nausea, vomiting, or diarrhea, is not typically associated with anaphylaxis. Instead, it may be a symptom of other conditions or reactions.
28.
True or False: Anaphylaxis of any severity should be considered a medical emergency
Correct Answer
A. True
Explanation
Anaphylaxis is a severe and potentially life-threatening allergic reaction that can occur within seconds or minutes of exposure to an allergen. It can cause symptoms such as difficulty breathing, swelling of the throat, low blood pressure, and loss of consciousness. Without prompt medical intervention, anaphylaxis can be fatal. Therefore, regardless of the severity of the reaction, anaphylaxis should always be considered a medical emergency and requires immediate treatment.
29.
What is the adult dose of epinephrine to a patient in anaphylaxis?
Correct Answer
B. 0.3ml of 1:1000
Explanation
The adult dose of epinephrine to a patient in anaphylaxis is 0.3ml of 1:1000. This means that 0.3ml of epinephrine solution with a concentration of 1:1000 is administered to the patient. This dosage is recommended to effectively treat anaphylaxis in adults.

What is the child dose of epinephrine for a patient in anaphylaxis?
Correct Answer
A. 0.15ml of 1:1000
Explanation
The correct answer is 0.15ml of 1:1000. In anaphylaxis, epinephrine is administered to help relieve symptoms and improve breathing. The child dose of epinephrine is typically 0.15ml of a 1:1000 concentration. This means that in each milliliter of solution, there is 1mg of epinephrine. This dose is appropriate for children experiencing anaphylaxis and can be administered using an auto-injector device.
31.
_________ is an overabundance of mast cells that carries an increased risk for anaphylaxis
Correct Answer
C. Mastocytosis
Explanation
Mastocytosis is a condition characterized by an overabundance of mast cells, which are a type of immune cell involved in allergic reactions. This condition carries an increased risk for anaphylaxis, a severe and potentially life-threatening allergic reaction. Phagocytosis is the process by which cells engulf and destroy foreign particles, while the complement system is a part of the immune system that helps to enhance the body's ability to fight off infections. Therefore, neither phagocytosis nor the complement system are associated with an overabundance of mast cells or an increased risk for anaphylaxis.
32.
Who is not responsible for ensuring all military/non military personnel under their jurisdiction receive required immunizations?
Correct Answer
C. Primary vaccine coordinators
Explanation
Primary vaccine coordinators are not responsible for ensuring all military/non military personnel under their jurisdiction receive required immunizations.
