NSG 3280 Pathophysiology Galen College Of Nursing | Exam 4 Practice Questions And Answers |
Updated Tests
What is a physical and mechanical barrier? - (ANSWER)Pg. 143- Intact physical barriers act as a blockage
to foreign material entering the body. Ex: The constant shedding of the epidermis and mucosal
membranes aids in the removal of any micro organisms that attach to their surface
What is the difference between direct and indirect transmission? - (ANSWER)Pg. 148
Direct (droplet) Ex: Sexual intercourse, or kissing
Indirect (Airborne) Ex: Measles
What is neutropenia and how does this put a pt at risk for acquiring diseases? - (ANSWER)Neutropenia is
an absolute neutrophil count less than 500.
Affected pts are required protective isolation to prevent infections.
An opportunistic infection is an infection caused by pathogens (bacteria, viruses, fungi, or protozoa) that
take advantage of an opportunity not normally available, such as a host with a weakened immune
system, an altered microbiota (such as a disrupted gut microbiota), or breached integumentary barriers.
What are common characteristics of asthma? - (ANSWER)Pg. 479
Airway obstruction that is reversible
Airway inflammation
Wheezing, dyspnea, and cough
If asthma is not treated properly it could develop into what two other conditions? -
(ANSWER)Emphysema and Bronchitis
Which race/ethnicities are most at risk for developing asthma? Pg. 479 - (ANSWER)Asthma is the most
common chronic disease of childhood with a disproportionally high prevalence rate in African
Americans, inner city dwellers and premature/low birth weight babies

Updated Tests
Asthma is associated with the release of inflammatory chemicals from mast cells in the airways. The
mechanisms stimulating the mast cell release are called what? - (ANSWER)Pg. 479 Immunoglobulin (IgE)
What does peak expiratory flow rate check? - (ANSWER)Pg. 479 Best indictor of a reduction in airflow
Can asthma be allergy specific? Please explain. - (ANSWER)Pg. 479 Allergic asthma (extrinsic) comprises
of approximately 1/3 of all cases. Asthma is often associated with a history of hay fever or eczema, a
positive history of disease, and positive skin test reaction to allergens (dust)
What causes exercise-induced asthma? - (ANSWER)Pg. 479 A mediator is released that causes bronchial
constriction while exercising (basophils and tissue mast cells)
What is the pathology of exercise induced asthma? - (ANSWER)Pg. 479 Heat loss, water loss, and
increased osmolality of the lower respiratory mucosa are believed to stimulate mediator release from
basophils and tissue mast cells. This mediator release produces airway smooth muscle constriction.
What is intrinsic asthma and who is likely to develop this? - (ANSWER)Pg. 479 Intrinsic (Nonallergic)
asthma frequently develops in middle age adults and has a less favorable prognosis.
Please explain occupational asthma - (ANSWER)Pg. 479 Asthma that is usually caused by inhaled dust or
fumes in the work environment
Please explain what an episode of status asthmaticus would look like? - (ANSWER)Pg. 481-482 Shown as
prolonged bronchospasm, severe hypoxia, and unresponsive to routine treatment
How would a client present who is having an asthma attack? - (ANSWER)Pg. 481 wheezing, tachy (due to
the oxygen level being decreased from bronchospasm) dyspnea, cough, and SOB
