Question

2 multiple choice 1 point the incidence of a disorder within a specified time frame and a specified population: refers to the etiology of a given disorder cannot be lower than the prevalence of that disorder cannot be higher than the prevalence of that disorder refers to the prognosis of recovering from that disorder refers to the mortality rate of that disorder

Explanation:

• Etiology refers to the cause of a disorder, not incidence.
• Prevalence is the total number of existing cases in a population, while incidence is new cases in a time frame. Since incidence only counts new cases, it cannot exceed the total existing (and new) cases that make up prevalence, so incidence cannot be higher than prevalence.
• Prognosis is the outlook for recovery, unrelated to incidence.
• Mortality rate is the death rate from a disorder, not incidence.

Answer:

cannot be higher than the prevalence of that disorder
