CER Scope Inspection and Testing 2

Question 1

During pre-cleaning inspection, a technician notices the insertion tube has a slight spiral twist. What is the correct action?

Accepted Answer

Immediately remove from service and notify the biomedical department

Answer

A spiral twist in the insertion tube indicates internal channel or coil damage and the scope must be removed from service pending inspection by a qualified repair technician.

Question 2

Which tool is used to verify that suction and biopsy channel lumens meet the minimum diameter specification during scope inspection?

Accepted Answer

Channel diameter gauge or brush compatibility chart

Answer

A channel diameter gauge or the manufacturer's brush compatibility chart is used to confirm lumen diameter is within specification so correct-sized brushes can be selected.

Question 3

When performing a leak test on a videoscope, the endoscope must be tested:

Accepted Answer

Dry, before any contact with water or cleaning solution

Answer

The leak test must be performed on a dry scope before immersion to detect existing damage before fluids can enter and worsen internal damage.

Question 4

A steady stream of bubbles rising from the universal cord during a leak test most likely indicates:

Accepted Answer

A breach in the outer sheath of the universal cord

Answer

Continuous bubbling from the universal cord during a leak test indicates a breach in the outer sheath, allowing pressurized air to escape into water.

Question 5

What is the purpose of bending the insertion tube in all four directions during the functional inspection?

Accepted Answer

To verify angulation wire and control wheel integrity

Answer

Flexing in all directions tests the angulation wires, control wheels, and bending section for damage that may restrict full tip deflection.
