Amember of the health care team is researching the etiology and pathogenesis of a number of clients who are under his care in a hospital context. which of the following aspects of clients' situations best characterizes pathogenesis rather than etiology? a. a client who has been exposed to the mycobacterium tuberculosis bacteriumb. a client who has increasing serum ammonia levels due to liver cirrhosisc. a client who was admitted with the effects of methyl alcohol poisoningd. a client with multiple skeletal injuries secondary to a motor vehicle accident

The correct answer is B. A client who has increasing serum ammonia levels due to liver cirrhosis

Explanation:

Etiology is the study of origin or cause of any disease. Pathogenesis is the mechanism of causing disease by any pathogen. Pathogens use four-step to become pathogenic which are contact, colonization, invasion, and infection.  

In pathogenesis the symptoms of disease is observed not the cause so in option B increasing serum ammonia level is the symptom of liver cirrhosis which characterize pathogenesis rather than etiology and in other option, only cause of a medical condition is described so the correct answer is B.

the earth is thought to have been formed about 4.6 billion years ago by collisions from a cloud of hydrogen, helium, rock, ice and other materials. these were pulled together by gravity to form objects in and around earth like- asteroids and small early planets called planetesimals.

so, the best possible answer to this question will be option d- to harden materials to form different parts of earth’s layers

because photosynthesis could not occur (apex)
