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?
Correct Answer: C
Rationale: The correct answer is C: A 6-hour glucose tolerance test. This test involves measuring blood glucose levels at specific intervals after consuming a glucose solution, providing a comprehensive assessment of glucose utilization over time. This test is particularly useful in evaluating how the body processes glucose after a meal and can help diagnose conditions such as diabetes.
A: A fasting blood glucose test would not provide a comprehensive picture of glucose utilization over time since it only measures glucose levels in a fasted state.
B: A test of serum glycosylated hemoglobin (HbA1c) reflects average blood glucose levels over the past 2-3 months but does not directly assess glucose utilization after a meal.
D: A test for urine ketones is used to detect ketones in the urine, which can indicate diabetic ketoacidosis but does not directly measure glucose utilization.
