A patient has been prescribed antacids and an antibiotic to eradicate Helicobacter pylori. The diagnosis is most likely

A. His body does not produce any insulin so he must receive insulin injections: Type I diabetes is characterized by the destruction of pancreatic beta cells, resulting in little to no insulin production. Therefore, insulin must be administered via injection to replace the insulin the body cannot produce.

B. The pills are not as effective as the insulin injections: While this might be partially true for Type I diabetes, it is not the complete answer. Oral medications are generally not effective in Type I diabetes because they stimulate the pancreas to produce insulin, which is not possible in these patients.

C. He will only be on insulin injections for a short while, then he can take a pill: This is incorrect. Type I diabetes requires lifelong insulin therapy.

D. He can stop the insulin injections once his body begins to make insulin again: This is incorrect as Type I diabetes is a permanent condition where the body cannot produce insulin.

A. Positive Brudzinski's sign: A positive Brudzinski's sign, which involves involuntary flexion of the hips and knees when the neck is flexed, is a common finding in meningitis (both viral and bacterial).

B. Dysarthria and double vision: These symptoms are not typical of viral meningitis; they are more often associated with neurological disorders such as multiple sclerosis.

C. Petechiae and purpura: These are more commonly associated with bacterial meningitis, particularly meningococcal meningitis, rather than viral meningitis.

D. Positive Babinski's reflex: A positive Babinski’s reflex indicates an upper motor neuron lesion and is not specific to meningitis.
