NCCT PRACTICE EXAM WITH RATIONALES – 3-hour PRACTICE EXAM!
1. Forced Vital Capacity is measured by instructing the patient to
A. forcefully breathe air out and continue to exhale for at least 6 seconds.
B. complete a minimum of eight acceptable efforts to validate the test.
C. move the one way valve to a minimum of 4000 ml capacity.
D. blow out as fast and hard as possible and document the highest
reading. Correct response:
forcefully breath air out and continue to exhale for at least 6 seconds.
Rationale: Respiratory tests are performed to assess and/or monitor lung function. A spirometer
measures how fast and how much air is pushed/forced out of the lungs. Forced Vital Capacity (FVC) is
measured by instructing the patient to forcefully breath air out and continue to exhale for at least 6
seconds. When doing spirometry testing, the total attempts should be limited to 8, not a minimum of 8.
The one way valve should not be moved to 4000 mL capacity. A patient should blow out as hard and fast
for as long as possible, and 3 acceptable attempts are documented to ensure test validity (not just the
highest reading).
2. Healthcare services for the evaluation and management of a disease consistent with the standard
of care are considered to be
A. V codes.
B. a medical necessity.
C. upcoding.
D. part of the audit
process. Correct response:
a medical necessity.
Rationale: A medically necessary healthcare service is generally the least invasive, most effective
treatment that is “reasonable and necessary” for the patient condition (i.e. standard of care). V codes
are used for non-injury or non-disease encounters (i.e. suture removal, infectious disease exposure,
etc.). Upcoding is the fraudulent act of submitting CPT codes for services that will reimburse at a higher
rate than the actual services provided. Part of the audit process is to help reduce fraud or unnecessary
treatment billed to insurance.
3. Which of the following techniques is correct when collecting a throat culture?
A. Depress the patient’s tongue and place the swab in a viral media tube following collection.
B. Insert swab into the nostril and rub against the turbinate to absorb mucous.
C. Use a tongue depressor and swab both sides of the throat.
