EXAM
1. Where is the V4 lead placed in a standard 12-lead EKG?
A. Fourth intercostal space, right of the sternum
B. Fourth intercostal space, left of the sternum
C. Fifth intercostal space, midclavicular line
D. Fifth intercostal space, anterior axillary line
Answer: C
Conceptual Explanation: V4 is placed at the fifth intercostal space at the midclavicular
line.
2. When performing a venipuncture, which tube should be drawn first according to the
standard order of draw?
A. Blood culture (SPS)
B. Coagulation (Light Blue)
C. Serum (Red/Gold)
D. Hematology (Lavender)
,Answer: A
Conceptual Explanation: Blood cultures or yellow (SPS) tubes are always drawn first to

3. Which of the following is the normal range for a PR interval on an EKG tracing?
A. 0.04 to 0.10 seconds
B. 0.12 to 0.20 seconds
C. 0.20 to 0.40 seconds
D. 0.06 to 0.12 seconds
Answer: B
Conceptual Explanation: A normal PR interval ranges from 0.12 to 0.20 seconds,
representing the time from atrial depolarization to ventricular depolarization.
4. A patient is scheduled for a glucose tolerance test (GTT). How long should they fast before
the procedure?
A. 4 to 6 hours
B. No fasting required
C. 24 hours
D. 8 to 12 hours

B. Only using gloves when blood is visible
C. Treating all body fluids as if they are infectious
D. Wearing a gown for every patient interaction
