Question 1
A nurse is reviewing the chart of a patient who was exposed to a known viral pathogen 10 days
ago but has not yet reported feeling ill. The time interval between the patient’s exposure to the
pathogen and the appearance of the first signs and symptoms is defined as which period of
pathogenesis?
A. Latent period B. Prodromal period C. Convalescence D. Incubation period
--------------------------------------------------------------------------------
Question 2
A patient admitted to the hospital for pneumonia develops acute kidney injury (AKI) 48 hours
after receiving an intravenous aminoglycoside antibiotic. The patient asks why this new kidney
problem occurred. The nurse should explain that the AKI is an example of which type of
etiology?
A. Idiopathic B. Endemic C. Iatrogenic D. Risk factor
--------------------------------------------------------------------------------
Question 3
The nurse is educating a student about the body's acute stress response. Which physiological
effects are specifically attributed to the release of catecholamines (Epinephrine and
Norepinephrine)? (Select All That Apply)
A. Increased heart rate B. Decreased insulin secretion C. Increased heart contractility (strength
of contraction) D. Blood vessel constriction E. Bronchodilation
--------------------------------------------------------------------------------
Question 4
, lOMoAR cPSD| 65448581
A patient with hypertension is diagnosed with physiological cardiac changes. The enlargement
of the patient's heart muscle cells is an example of which cellular adaptation, and what is the
underlying cause?
A. Atrophy; caused by disuse B. Hyperplasia; caused by persistent injury C. Hypertrophy; caused
by increased demands on the cell D. Dysplasia; caused by an incorrect adaptive response
--------------------------------------------------------------------------------
Question 5
A patient suffers a severe ischemic stroke. The nurse anticipates that the resulting cell death in
the brain tissue will most likely manifest as which type of necrosis, characterized by quick
lysosomal destruction of dead cells and tissue?
A. Caseous necrosis B. Fat necrosis C. Coagulative necrosis D. Liquefactive necrosis
--------------------------------------------------------------------------------
Question 6
A community health nurse is developing a program aimed at reducing the incidence of obesity
by hosting educational sessions on nutrition and encouraging physical activity among
susceptible individuals. This initiative aligns with which level of prevention?
A. Primary B. Secondary C. Tertiary D. Convalescence
--------------------------------------------------------------------------------
Question 7
The release of cortisol during the resistance stage of the General Adaptation Syndrome has
profound metabolic effects. Which findings are direct effects of increased cortisol levels? (Select
All That Apply)
A. Increased breakdown of tissues into amino acids B. Decreased acute immune and
inflammatory response C. Gluconeogenesis D. Decreased appetite E. Increased brain cell use of
glucose
--------------------------------------------------------------------------------
Question 8
A patient enters the General Adaptation Syndrome due to chronic stress. The body attempts to
manage the challenge by adapting and restoring balance,
but this adaptation results in a new, slightly elevated set point for physiological parameters. This
adaptive process is best described as:

--------------------------------------------------------------------------------
Question 9
A lung biopsy from a patient suspected of having tuberculosis reveals dead cells that are "walled
off" by the surrounding tissue and have a white, clumpy appearance. This finding is
characteristic of which specific type of necrosis?
A. Fat necrosis B. Coagulative necrosis C. Caseous necrosis D. Liquefactive necrosis
--------------------------------------------------------------------------------
Question 10
The mechanism of reversible cell injury known as hydropic swelling is fundamentally caused by:
A. Accumulation of abnormal, faulty metabolic substances. B. Malfunction of the Na+/K+ pump
due to decreased ATP production. C. Cellular damage leading to activation of programmed cell
death pathways. D. Ischemia causing enzymes to break down cell walls.
--------------------------------------------------------------------------------
Question 11
Fill in the blanks: A disease that is found to be native to and consistently prevalent in a specific
region of the United States is categorized epidemiologically as ________. However, if the
disease suddenly affects a large geographic area globally, such as multiple continents, it is
categorized as a __________.
--------------------------------------------------------------------------------
Question 12
A patient experiences a sudden, intense stressor. In the initial "Alarm" stage of the General
Adaptation Syndrome, the nurse would anticipate which immediate hormonal response?
A. Decreased cortisol and decreased catecholamines B. Decreased resistance to stressors and
increased cortisol C. Resolution of excesses and initiation of adaptation D. Prolonged exposure
causing an inability to return to homeostasis
--------------------------------------------------------------------------------
Question 13
A chronic smoker has been diagnosed with a condition where the normal epithelial cells of the
respiratory tract have been replaced by a different, but structurally mature, type of cell. If this
process progresses and the cells subsequently become disorganized and vary in size and shape,
the nurse knows the progression is from:
