A patient has recently been diagnosed with multiple sclerosis. Which response best explains the etiology of multiple sclerosis (MS)?

A.

The disease is prevalent in certain geographical locations.

B.

There is a well-defined genetic cause.

C.

Inflammatory processes are responsible for the signs and symptoms.

D.

Ischemic lesions in the brain are responsible for the signs and symptoms.

Answer and Explanation

The Correct Answer is C

A. The disease is prevalent in certain geographical locations: This statement is true but does not explain the etiology of MS. Geographic prevalence does not address the underlying cause.

B. There is a well-defined genetic cause: While genetics may play a role in MS, there is no single well-defined genetic cause for the disease.

C. Inflammatory processes are responsible for the signs and symptoms: MS is an autoimmune disease characterized by inflammation and demyelination of the central nervous system, leading to the signs and symptoms of the disease.

D. Ischemic lesions in the brain are responsible for the signs and symptoms: MS is primarily caused by demyelination rather than ischemic lesions.

Explanation

26. A patient is admitted to the emergency department (ED) following an overdose of acetaminophen (Tylenol) and is diagnosed with cirrhosis. Which laboratory finding is consistent with the diagnosis?

  1. elevated serum protein hyperproteinemia
  2. decreased serum liver enzymes (ALT).
  3. elevated number of platelets thrombocytosis)
  4. decreased level of clotting factors.

Correct answer:

A. Elevated serum protein hyperproteinemia: In cirrhosis, serum protein levels, particularly albumin, are often decreased due to impaired liver synthesis.

B. Decreased serum liver enzymes (ALT): In cirrhosis, liver enzyme levels such as ALT (alanine aminotransferase) are typically elevated due to liver damage and inflammation.

C. Elevated number of platelets (thrombocytosis): Cirrhosis often leads to thrombocytopenia (decreased platelet count) due to splenomegaly and decreased production of thrombopoietin.

D. Decreased level of clotting factors: The liver synthesizes most clotting factors, and in cirrhosis, the production of these factors is impaired, leading to decreased levels and increased bleeding risk.
