UPDATED ACTUAL Questions and
CORRECT Answers
How will the body respond to a MRSA infection? - CORRECT ANSWER - The immune
response against S. aureus involves the activation of both the innate and adaptive immune
systems. The body will respond with inflammation. Inflammation causes redness, swelling, pain,
heat, and maybe loss of function. The body will activate phagocytic cells in an effort to engulf
the pathogen. T cells will also activate and B cells will produce antibodies that target the bacteria
antigens.
How does the body respond to a malaria infection? - CORRECT ANSWER - Malaria is a
protozoa. The body detects the parasite when they mature in the blood cells. Immune cells are
released to attack and kill the parasites.
How does the body respond to a staph infection? - CORRECT ANSWER - he body
respond to a staph infection similar in how it responds to MRSA. MRSA is a staph infection.
(Staphylococcus Aureus)
What is the difference between active and passive immunity? - CORRECT ANSWER -
Active immunity results from the production of antibodies by the immune system in response to
the presence of an antigen. Passive immunity is when antibodies from another person or animal
are introduced into an individual's body such as through immunizations
Describe the behavior of non-hodgkins lymphoma - CORRECT ANSWER - Non-
hodgkins lymphoma is a malignant tumor. They are characterized by painless lymph node
swelling. The tumors can be either slow or fast growing.
Describe the process of metastisis - CORRECT ANSWER - Metastasis is the spreading
process of cancer throughout the body. Cancer cells break away from the original tumor. They
travel through the lymph or the blood and form a new tumor in a different part of the body.
,What is the body's natural defense mechanism to near-drowning? - CORRECT
ANSWER - Near drowning is when an individual aspirates fluid into their lungs or has an
obstructed airway caused by a spasm of the larynx when gasping underwater. An individual can
experiences respiratory distress later on. The body has an instinctive drowning response which is
to keep the mouth above water to the exclusion of useful effort to attract help or self-rescue. The
body will also cough to remove any fluid from the lungs.
What is the body's natural defense mechanism to asphixation? - CORRECT ANSWER -
The body has mechanisms where the vocal folds and aryepiglottic folds adduct which help
prevent material from entering the lower airway. The body also can cause retching to remove any
obstruction within the airway.
What is the body's natural defense mechanism to allergies? - CORRECT ANSWER - The
body responds to allergies by producing antibodies that cause the allergic reaction. The primary
focus is to remove the allergen from the body by sneezing, coughing, and the eyes tearing.
What is a greenstick fracture? - CORRECT ANSWER - Greenstick: A greenstick fracture,
commonly seen in children due to the softness of their bones, in which the bone is partially bent
and split. This resembles the breaking pattern of a green stick of twig.
What is the difference between a sprain and a strain? - CORRECT ANSWER - A sprain is
an injury to the ligaments and capsule at a joint whereas a strain is an injury to muscles or
tendons.
What is Rickets? - CORRECT ANSWER - Rickets is a disease in children caused by
Vitamin D deficiency. It is characterized by imperfet calcification, softening, and a dsitortion of
the bones. It can be diagnosed through blood tests or possibly imaging such as an Xray or DEXA
scan. Rickets is treated through a supplementation of Vitamin D and Ca.
What is chronic renal failure? - CORRECT ANSWER - The irreversible loss of renal
function that affects nearly all organ systems
What is the treatment for rickets? - CORRECT ANSWER - Vitamin D and calcium diet
and/or supplements. UV light exposure
, What is osteomyelitis? - CORRECT ANSWER - infection of the bone forming tissue. It is
caused by trauma that results in a hematoma forming in the bone. Typically the infection is
Staphylococcus aureus. It is diagnosed through physical examinations of the site, blood cultures,
and scans of the bones to determine how extensive the infection is.
How is osteomyelitis treated? - CORRECT ANSWER - It is treated with antibiotics and
bed rest. Tissue or bone grafts may be necessary.
What is gout? - CORRECT ANSWER - Gout is a chronic disorder of uric acid
metabolism. Crystals of uric acid compounds appear in the synovial fluid of the joints of the
extremities. It is diagnosed through the identification of urate cystals in the joint fluid, urinalysis,
blood tests such as WBC and ESR, and imaging to determine the extent of the issue.
What is the treatment for gout? - CORRECT ANSWER - Treatment includes bed rest,
immobilization of the area, heat and cold applied to the area, and NSAIDs.
What is plantar fasciitis? - CORRECT ANSWER - Plantar fascitis is the irritation of the
ligament at the bottom of the foot that connects the heel to the toes. This ligament supports the
arch of the foot and is caused by strain and tearing. It can be caused by having high arches,
pregnancy, or walking, standing, or running for long periods of time, particularly when doing
such on hard surfaces. The symptoms include pain or stiffness in the foot. It is diagnosed through
physical examination. Xrays may be ordered to rule out any other injury.
How is plantar fasciitis treated? - CORRECT ANSWER - NSAIDs, rest, and ice are
standard treatments.
What is Paget's Disease? - CORRECT ANSWER - is a chronic metabolic skeletal disease.
It is marked by high bone turnover in the initial phase of the disease. The replaced bone is coarse
and has an irregular consistency. In later phases the disease is characterized by normal bone
being replaced with a highly vascular fibrous tissue. It is diagnosed through bone scans, XRays,
bone marrow biopsies, blood analysis, and urinalysis.
