  1. Which tube color is used for coagulation studies such as PT and aPTT?

    Answer: Light blue

    Light blue (sodium citrate) tubes are used for coagulation studies and must be filled to exactly the correct volume.

  2. A fasting blood glucose level of 126 mg/dL on two separate tests is diagnostic of which condition?

    Answer: Diabetes mellitus

    A fasting glucose ≥126 mg/dL on two occasions meets the ADA diagnostic criterion for diabetes mellitus.

  3. Which imaging modality uses sound waves to create real-time images of soft tissue structures?

    Answer: Ultrasound

    Ultrasound uses high-frequency sound waves and is particularly useful for visualizing soft tissues, organs, and blood flow.

  4. The normal reference range for adult hemoglobin in males is approximately:

    Answer: 13.5–17.5 g/dL

    Normal adult male hemoglobin is 13.5–17.5 g/dL; values below this range indicate anemia.

  5. Which blood test is the best indicator of long-term glycemic control over approximately 3 months?

    Answer: Hemoglobin A1c

    Hemoglobin A1c reflects average blood glucose over the lifespan of red blood cells (~90 days).

  6. When collecting a 24-hour urine specimen, which instruction is correct?

    Answer: Discard the first morning void, then collect all urine for 24 hours

    The first void is discarded to establish a baseline; all subsequent urine for 24 hours is collected and refrigerated.

  7. An ECG finding of a prolonged PR interval (>0.20 seconds) indicates:

    Answer: First-degree AV block

    A PR interval longer than 0.20 seconds (one large box) indicates first-degree AV block, a delay in conduction through the AV node.
