, What criterion establishes the diagnosis of diabetes in the older adult?
A) Blood glucose concentration 2 hours after an oral glucose intake that is
greater than 125mg/dL during an oral glucose tolerance test.
B) Symptoms of disease and a random blood glucose concentration greater
than 350mg/dL.
C) Fasting blood glucose concentration greater than or equal to 225 mg/dL
D) Blood glucose concentrations 2 hours after an oral glucose intake that is
greater than or equal to 200 mg/dL during an oral glucose tolerance test. -
Answer: D) Blood glucose concentrations 2 hours after an oral glucose
intake that is greater than or equal to 200 mg/dL during an oral glucose
tolerance test.
Rationale: Of the diagnostic tests for diabetes mellitus, the oral glucose
tolerance test is the most effective. Diagnosis is usually established when
the oral glucose intake is greater than or equal to 200 mg/dL during the oral
glucose tolerance test. A blood glucose level greater than 125 mg/dL is
insufficient to establish the diagnosis of diabetes; levels greater than or
equal to 225 mg/fL and greater than 350 mg/dL are higher than the
minimum necessary to establish the diagnosis.
Why are first generation antihistamines (e.g., diphenhydramine [Benadryl])
considered inappropriate for the older adult?
A) These drugs have anticholinergic effects and should not be administered
to the older adult.
B) These drugs cause euphoria in the older adult.
C) These drugs cause the older person to wander during the nighttime
hours.
