Laboratory studies indicate a client's blood pressure level is 185mg/dl. Two hours have passed since the client ate breakfast. Which test would yield the most occlusive diagnostic information about the client's glucose utilization?

  • A. A fasting blood glucose test
  • B. A test of serum glycosylated hemoglobin (HbA1c)
  • C. A 6-hour glucose tolerance test
  • D. A test for urine ketones
Correct Answer: C

Rationale: A 6-hour glucose tolerance test would yield the most occlusive diagnostic information about the client's glucose utilization in this case. The elevated blood pressure level of 185 mg/dL two hours after breakfast indicates poor glucose regulation. A glucose tolerance test involves monitoring the client's blood glucose levels over a period of time after ingesting a glucose solution. This test provides a comprehensive assessment of how the body processes glucose, revealing any abnormalities in glucose metabolism beyond fasting levels, such as postprandial (after-meal) glucose spikes and prolonged hyperglycemia. This can help identify conditions like insulin resistance, impaired glucose tolerance, or diabetes, which may not be evident from a fasting blood glucose test alone. Glycosylated hemoglobin (HbA1c) reflects average blood sugar levels over the past 2-3 months and would not provide immediate information about the client's current glucose metabolism. Urine ketones
