Title: 2.5- Lesson Two Quiz
Course: 14SP-HIS-170-G101-CLINICAL PRACTICUM I

This quiz consists of 10 multiple choice questions.  It is due by Tuesday Oct. 29th.  Keep the following details in mind before you open the quiz:

1. All the questions should be visable when you open the quiz.
2. It must be completed in one session.
3. The time limit is one hour.
4. While it is considered open book you will do better if you have completed the lesson first and don't let the quiz sit idle for too long to look up answers.
5. Learning the information and taking the quiz with as little help from your notes as possible will help you prepare for the midterm.

Q: Audiometers should be calibrated every __________ .
- month
- day
- annually
- bi-annually
A: annually
If wrong: annually

Q: A sound level meter is:
- a device for measuring the vibration of sound.
- a device for measuring the intensity of sound waves in the air.
- a device for measuring the difference between sound waves in the air and vibrations of the mastoid.
- none of the above.
A: a device for measuring the intensity of sound waves in the air.
If wrong: a device for measuring the intensity of sound waves in the air.

Q: The definition of intensity is:
- the amount of sound energy per unit of area.
- the amount of sound vibration squared.
- the amount of sound energy measured on 100 normal hearing individuals.
- all of the above.
A: the amount of sound energy per unit of area.
If wrong: the amount of sound energy per unit of area.

Q: Biologic checks are important because:
- are only important if you haven't had your equipment calibrated.
- you are required to do them by most facilities and some state laws.
- you are required to do them for this program.
- improperly working equipment can affect test results.
A: improperly working equipment can affect test results.
If wrong: improperly working equipment can affect test results.

Q: An artificial mastoid is used to calibrate:
- air conduction earphones
- bone conduction ossilators.
- insert earphones.
- all of the above.
A: bone conduction ossilators.
If wrong: bone conduction ossilators.

Q: It is important to know the amount of ambient noise in the test environment because:
- the client may not hear the instructions clearly.
- it may affect the accuracy of the test results.
- it may distract the client during the testing procedures.
- it may distract the tester during test procedures.
A: it may affect the accuracy of the test results.
If wrong: it may affect the accuracy of the test results.

Q: If the client responds when no tone has been presented this is called a:
- no response
- false negative response
- hyperactive response
- false positive response
A: false positive response
If wrong: false positive response

Q: A false negative response suggests hearing is:
- better than it actually is
- worse than it actually is
- an accurate pure tone threshold
- thresholds are about 10dB better than reported
A: worse than it actually is
If wrong: worse than it actually is

Q: Acceptable client responses to pure tones include:
- raising hand or finger
- saying yes
- either a or b
- neither a or b
A: either a or b
If wrong: either a or b

Q: The pure tone average is typically the average of which frequencies:
- 500Hz, 1000Hz, 1500Hz
- 1000Hz, 2000Hz, 4000Hz
- 500Hz, 2000Hz, 4000Hz
- 500Hz, 1000Hz, 2000Hz
A: 500Hz, 1000Hz, 2000Hz
If wrong: 500Hz, 1000Hz, 2000Hz
