C) yields inconsistent results when repeated.
D) does not reflect the status of the population as a whole.
2. A physician is providing care for a number of clients on a medical unit of a large

cause disease. Which client most clearly demonstrates the consequences of molecules
that cause disease?

packed red blood cells.
B) A 91-year-old woman who has experienced an ischemic stroke resulting from
familial hypercholesterolemia.
C) A 19-year-old man with exacerbation of his cystic fibrosis requiring oxygen
therapy and chest physiotherapy.
D) A 30-year-old homeless man who has pneumocystis carinii pneumonia (PCP) and
is HIV positive.
3. A member of the healthcare team is researching the etiology and pathogenesis of a
number of clients who are under her care in a hospital context. Which aspect of client's
situations best characterizes pathogenesis rather than etiology?
A) A client who has been exposed to the mycobacterium tuberculosis bacterium.
B) A client who has increasing serum ammonia levels due to liver cirrhosis.

4. A client has been admitted for exacerbation of his chronic obstructive pulmonary
disease (COPD), and a respiratory therapist (RT) is assessing the client for the first time.
Which aspect of the client's current state of health would be best characterized as a
symptom rather than a sign?
A) The client's oxygen saturation is 83% by pulse oximetry.
B) The client notes that he has increased work of breathing when lying supine.
C) The RT hears diminished breath sounds to the client's lower lung fields bilaterally.
D) The client's respiratory rate is 31 breaths per minute.
5. Nurses are discussing a new blood test that helps establish a differential diagnosis
between shortness of breath with a cardiac etiology and shortness of breath with a
respiratory/pulmonary etiology. A positive result is known to indicate a cardiac
etiology. The marketers of the test report that 99.8% of clients who have confirmed
cardiac etiologies test positive in the test. However, 1.3% of clients who do not have
cardiac etiologies for their shortness of breath also test positive. Which statement best
characterizes this blood test?
A) Low validity, high reliability
B) High sensitivity, low specificity
C) High specificity, low reliability
D) High sensitivity, low reliability
6. As part of a screening program for prostate cancer, men at a senior citizens centre are
having their blood levels of prostate-specific antigen (PSA) measured. Which statement
would best characterize high positive predictive value but low negative predictive value
for this screening test?
A) All of the men who had high PSA levels developed prostate cancer; several men
who had low PSA levels also developed prostate cancer.
B) All of the men who had low PSA levels were cancer free; several men who had
high levels also remained free of prostate cancer.
C) Men who had low PSA levels also displayed false-positive results for prostate
cancer; men with high levels were often falsely diagnosed with prostate cancer.
D) The test displayed low sensitivity but high specificity.
7. A particular disease has a debilitating effect on the ability of sufferers to perform their
activities of daily living and is a significant cause of decreased quality of life. However,
few people die as a result of the disease's direct effects. There are hundreds of thousands
of Canadians living with the disease but relatively few new cases in recent years. This
disease has:
A) low mortality, high morbidity, low prevalence, and high incidence.
B) low mortality, high morbidity, high incidence, and low prevalence.
C) high mortality, low morbidity, high incidence, and low prevalence.
D) high morbidity, low mortality, high prevalence, and low incidence.

8. A researcher has recruited a large number of mothers whose infants were born with
cardiac defects, as well as mothers whose infants were born with healthy hearts. The
researcher is comparing the nutritional habits of all the mothers while their babies were
in utero. Which type of study is being conducted?
A) Cohort study
B) Randomized controlled trial (RCT)
C) Case-control study
D) Risk-factor study
9. A multidisciplinary healthcare team operates a program aimed at the prevention,
identification, and treatment of diabetes in a rural community. Which aspect of the
program would be most likely to be classified as secondary prevention?
A) Regularly scheduled wound-dressing changes for clients who have foot ulcers
secondary to peripheral neuropathy and impaired wound healing.
B) Teaching schoolchildren how a nutritious, traditional diet can lessen their chances
of developing adult-onset diabetes.
C) Staffing a booth where community residents who are attending a baseball
tournament can have their blood glucose levels checked.
D) Administering oral antihyperglycemic medications to clients who have a diagnosis
of diabetes.
10. An occupational therapist conducts a group therapy program called MindWorks with
older adults who have diagnoses of dementia and Alzheimer disease. The goal of the
group is to slow the cognitive decline of clients by engaging them in regular, organized
mental activity, such as reading maps and solving puzzles. How would the program
most likely be characterized?
A) Primary prevention
B) Secondary prevention
C) Tertiary prevention
D) Prognosis enhancement
11. The clinical educator of a hospital medical unit is establishing evidence-based practice
guidelines for the nursing care on the unit. Which statement most accurately captures a
guiding principle of the nurse's task?
A) Evidence-based practice guidelines will be rooted in research rather than nurses'
subjective practice preferences and experiences.
B) Guidelines are synonymous with systematic research reviews.
C) The need for continuity and standardization of guidelines will mean that they will
be fixed rather than changeable.
D) The guidelines will combine individual expertise with external systematic
evidence.

12. To best understand the study of pathophysiology, the nurse must have a clear
understanding of the term itself. Of the definitions below, which one best describes the
term pathophysiology?
A) The physiology of altered health
B) Any deviation from or interruption of the normal structure or function of any part,
organ, or system of the body
C) Causes of disease
D) Changes in structure or form that is characteristic of a disease
13. A physician is examining a 21-year-old college student who is exhibiting the classic
symptoms of schizophrenia. In the course of her evaluation the physician begins
developing a treatment strategy based on what she knows about the disease, available
therapies, and medications. She also makes the client aware of the consequences of not
following the treatment regimen. To accomplish this, what aspect of the disease is the
physician using?
A) Etiology
B) Causation
C) Natural history
D) Morbidity statistics
14. A client has died and the nurse is responsible for filling out the death certificate. In
performing this task, the nurse is required to record the client's age, sex, and cause of
death, among other factors. What is the purpose of reporting these statistics?
A) These statistics are recorded so pharmaceutical companies may compile the data to
determine future need.
B) The government requires the statistics in order to calculate the crude mortality rate.
C) These statistics are useful in terms of anticipating healthcare needs, planning
public-education programs, directing health research efforts, and allocating
healthcare dollars.
D) These statistics are required by the hospital to inform the WHO for the coding of
the cause of death.
15. Researchers have designed a study where the health of a large group of babies will be
followed for several years. What type of study is this?
