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 Americans living with the disease
but relatively few new cases in recent years.Which of the following statements
best conveys an
accurate epidemiological characterization of the
disease?

B.Low mortality; high morbidity;high incidence;low
prevalence
C.High mortality;low morbidity;high incidence;low
prevalence

curve.
B. if the lab result is above the 50% distribution,the result is considered
elevated.
C. all lab values are adjusted for gender and weight.
D. if the result of a very sensitive test is negative, that does not mean
the person is disease free.

therapist (RT) is assessing the client for the first time.Which of the
following aspects of the patient's current state of health
