Question 1
A centrifuge rotor holds tubes in paired positions. What is the best way to balance a 5 mL patient tube before centrifugation?
Correct Answer:
Place an equal-mass tube directly opposite it
Explanation:
A centrifuge should be balanced with tubes of approximately equal mass placed symmetrically opposite each other. Proper balancing reduces vibration, protects the rotor, and helps maintain safe operation.
Question 2
On the same centrifuge and with the same rotor radius, the speed is doubled. What happens approximately to relative centrifugal force?
Correct Answer:
It quadruples
Explanation:
Relative centrifugal force is proportional to the square of rotational speed. Doubling rpm increases RCF by 2 squared, or approximately fourfold, when rotor radius is unchanged.
Question 3
A microscope uses a 10x ocular and a 40x objective. What total magnification is produced?
Correct Answer:
400x
Explanation:
Total magnification equals ocular magnification multiplied by objective magnification. 10 x 40 = 400, so the specimen is viewed at 400x total magnification.
Question 4
A control material must be reconstituted with exactly 5.00 mL of water. Which device is most appropriate when the procedure requires the highest accuracy for a fixed volume?
Correct Answer:
Class A volumetric pipette
Explanation:
A Class A volumetric pipette is designed to deliver a specified volume with high accuracy and precision. Beakers, transfer pipettes, and graduated cylinders are less accurate for exact fixed-volume delivery.
Question 5
A laboratorian needs 0.125 mL of serum. How many microliters are required?
Correct Answer:
125 microliters
Explanation:
One milliliter equals 1,000 microliters. Therefore 0.125 mL x 1,000 = 125 microliters.
