SAMPLE QUESTIONS
To give you a preview, here are five sample questions from the book:

1) SAFE WORK PRACTICES
A skin cut is an example of which link in the chain of infection?
a. Infectious agent
b. Mode of transmission
c. Portal of entry
d. Reservoir

2) DATA AND SPECIMEN COLLECTION AND HANDLING
Tourniquets should be:
a. left on the arm for at least three minutes
b. removed after the needle is withdrawn
c. tight enough to slow arterial flow
d. tight enough to slow venous flow

3) PRE-ANALYTICAL PROCEDURES
A laboratory has an autoclave rule stating "Do not fill containers more than half full with liquids". If a lab technician has to prepare 220 ml of media for autoclaving, which of these volume containers would comply with the rule?
a. 200 mL
b. 300 mL
c. 400 mL
d. 500 mL

4) REAGENT PREPARATION
A lab technician is making a solution by combining 3 parts of a solute with 7 parts of water. How many millilitres of the solute and water are needed to make 100 mL of the solution?
a. 7 mL of solute and 3 mL of water
b. 10 mL of solute and 70 mL of water
c. 30 mL of solute and 70 mL of water
d. 70 mL of solute and 30 mL of water

5) COMMUNICATION AND INTERACTION
When drawing blood from a frightened child, you should:
a. bribe the child with candy
b. explain the procedure to the child in simple terms
c. say nothing to the child and just perform the procedure
d. tell the child that the needle won't hurt

Answers
1) c. Portal of entry
The portal of entry is the method a pathogen uses to enter a susceptible host. Examples include the respiratory tract, blood, mucous membranes, and broken skin.

2) d. tight enough to slow venous flow
The tourniquet should be tight enough to slow venous flow without affecting the arterial flow.

3) d. 500 mL
2 × 220 mL = 440 mL. This means only the 500 mL container can contain 220 mL without becoming more than half-full.

4) c. 30 mL of solute and 70 mL of water
3 + 7 is a total of 10 parts.

Therefore, the amount of solute needed:
100 mL × 3/10 = 30 mL

Amount of water needed:
100 mL × 7/10 = 70 mL

5) b. explain the procedure to the child in simple terms
When drawing blood from a scared child, explain the procedure in simple terms. Be honest with the child; don't lie by telling them the needle won't hurt. It's also good to have the parent hold the child when you take the blood, as this can be comforting.
