Complete Questions, Answers & Rationales
Question 1
A school nurse is implementing a clean-up campaign at a local elementary school
to combat environmental allergens. The nurse explains to the staff that certain
allergens are particularly problematic for children with respiratory conditions.
What is the most common allergic response disorder that this campaign aims to
help prevent?
• A. Anaphylaxis
• B. Asthma
• C. Contact dermatitis
• D. Urticaria (hives)
Answer: B. Asthma. Fungi are principle allergens that can trigger respiratory
allergic responses such as asthma. Allergens in the environment, particularly
those spread through air ducts and damp areas, are common triggers for asthma
in children. The clean-up campaign targets these environmental allergens to
reduce asthma exacerbations .
Question 2
A nurse is presenting a community education program about how the body
protects itself from infection. She explains the body's first and second lines of
defense.
,For each component of the immune system, indicate whether it is part of the
body's First Line of Defense or Second Line of Defense.
Component First Line of Defense Second Line of Defense
Intact skin X
Sweat (containing lysozyme) X
Neutrophils X
Fever X
Mucous membranes X
Rationale: The body's first line of defense includes physical and chemical barriers
such as intact skin, mucous membranes, and secretions like sweat and tears,
which contain antimicrobial enzymes like lysozyme . The second line of defense
includes internal processes such as inflammation, fever, and phagocytic cells like
neutrophils and macrophages .
Question 3
A nurse is administering hydrocortisone to a patient with a severe inflammatory
response. The patient asks how this medication works.
The nurse's response is based on the understanding that hydrocortisone mimics
a hormone secreted by the adrenal cortex. To what hormone is the nurse
referring?
• A. Aldosterone
• B. Testosterone
• C. Histamine
• D. Cortisol
,Answer: D. Cortisol. Cortisol is a glucocorticoid hormone secreted by the adrenal
cortex. It possesses potent anti-inflammatory, anti-allergic, and
immunosuppressive properties. Cortisol slows the release of histamine, stabilizes
lysosomal membranes, and suppresses the immune response, which is why
synthetic forms like hydrocortisone are used to treat severe inflammatory
responses .
Question 4
A patient with an allergic reaction asks the nurse how the inflammatory response
begins. The nurse explains that when the body is exposed to an antigen, certain
cells release histamine, which initiates the inflammatory cascade.
What type of white blood cell is primarily responsible for releasing histamine?
• A. Neutrophils
• B. Eosinophils
• C. Basophils
• D. Monocytes
Answer: C. Basophils. Basophils are granulocytic white blood cells that initiate the
inflammatory response by releasing histamine when exposed to an antigen. They
are also involved in allergic responses. Mast cells, which are similar to basophils
but found in tissues, also release histamine. Measuring the number of these cells
can give an indication of the severity of infection and inflammation in the body .
Question 5
A home health nurse is visiting an immunocompromised patient who has been
diagnosed with a Cryptococcus infection. The patient asks the nurse to explain
what type of organism this is.
What is the classification of Cryptococcus?
• A. Bacterium
• B. Virus
, • C. Fungus
• D. Protozoa
Answer: C. Fungus. Cryptococcus is a fungal organism. Fungal infections can be
life-threatening in immunodeficient patients. Fungi are also a common concern in
home environments, particularly in air conditioning ducts and damp areas, which
is why environmental control is crucial for immunocompromised patients .
Question 6
A community health nurse is investigating an outbreak of illness after a large
picnic. Several attendees became ill with similar gastrointestinal symptoms.
How was the pathogen most likely acquired?
• A. Indirect contact
• B. Common vehicle
• C. Airborne transmission
• D. Vector transmission
Answer: B. Common vehicle. Food at the picnic that was shared in common
became the vehicle for transmission. This is known as common vehicle
transmission, where multiple people are infected from a single contaminated
source such as food or water. This is distinct from vector-borne (insect), airborne
(droplet nuclei), or indirect contact (fomite) transmission .
Question 7
A nurse is teaching a family about infection control measures after a family
member is discharged home with a draining wound. The nurse emphasizes the
single most effective method to prevent the spread of infection.
What is the most effective method to control the spread of communicable
disease?
• A. Isolate the infected person from all contact with noninfected persons
