Chapters 1-15 | 100 Questions with Answers
Instructions: This exam contains 100 questions in three formats:
Questions 1-45: Straight Answer (select the best option)
Questions 46-75: "All-Correct-Except" (identify the one false
statement)
Questions 76-100: Complex Multiple Choice (A, B, C combinations)
The correct answer is provided directly below each question.
PART I: STRAIGHT ANSWER QUESTIONS (1-45)
1. The imaging technique that uses a transducer placed on skin
prepared with transmitting gel to send sound waves into the body
is:
1. computed tomography
2. magnetic resonance imaging
3. ultrasonography
4. fluoroscopy
Answer: 3. Ultrasonography uses a transducer placed on skin prepared
with transmitting gel. Sound waves are transmitted into the individual,
and echoes are received back to create images based on the echogenicity
of tissues.
,2. The procedure that involves inserting a needle into the
subarachnoid space to withdraw cerebrospinal fluid for testing is
called a:
1. cisternography
2. lumbar puncture
3. myelography
4. ventriculography
Answer: 2. Lumbar puncture or "spinal tap" is the insertion of a needle
into the subarachnoid space between the fourth and fifth lumbar
vertebrae to withdraw cerebrospinal fluid (CSF) for testing.
3. The test that measures the electrical response of the brain to
stimulation of specific sensory pathways is called:
1. electroencephalography
2. electromyography
3. evoked potentials
4. nerve conduction studies
Answer: 3. Evoked potentials are the measured electrical response of the
brain to stimulation of specific sensory pathways. Visual, auditory,
sensory, and motor evoked potentials can be performed.
4. The term for the loss of glucose from a blood sample due to
delayed centrifugation is:
1. hemolysis
2. lipemia
3. glycolysis
4. turbidity
Answer: 3. If centrifugation is delayed too long, the red and white blood
cells will consume (metabolize) the glucose. This loss of glucose is called
glycolysis.
,5. The condition in which an individual has impaired fasting
glucose between 110 and 125 mg/dL is called:
1. diabetes mellitus
2. pre-diabetes
3. metabolic syndrome
4. insulin resistance
Answer: 2. Impaired fasting glucose (IFG) is a form of pre-diabetes where
fasting blood glucose is between 110 and 125 mg/dL. These individuals
have increased risk of developing type 2 diabetes.
6. The condition in which blood pressure readings are high in the
physician's office but normal in other settings is called:
1. primary hypertension
2. secondary hypertension
3. white coat hypertension
4. resistant hypertension
Answer: 3. White coat hypertension (also called labile hypertension)
refers to high readings in the physician's office with normal readings in
other settings. Ambulatory blood pressure monitoring can help diagnose
this condition.
7. The term for an increase in the size of cells, rather than an
increase in their number, is:
1. hyperplasia
2. hypertrophy
3. dysplasia
4. metaplasia
Answer: 2. Hypertrophy is an increase in cell size, whereas hyperplasia is
an increase in the number of cells. Both can occur in response to
increased demand or stimulation.
, 8. The test that measures the protein produced in the prostate
and is used for cancer screening is:
1. CEA
2. AFP
3. PSA
4. CA-125
Answer: 3. Prostate-specific antigen (PSA) is a protein produced in the
prostate. Levels increase in cancer, benign prostatic hypertrophy (BPH),
and inflammation (prostatitis).
9. The term for a driver's license suspension that occurs before
conviction when a driver fails or refuses to take a chemical test
is:
1. implied consent violation
2. administrative license suspension
3. zero tolerance suspension
4. conditional privilege revocation
Answer: 2. Under a procedure called administrative license suspension,
driving privileges are suspended before conviction when a driver fails or
refuses to take a chemical test. This is separate from court-imposed
penalties.
10. The type of statistical measure that indicates how much
mortality risk exists for a specific group compared to a reference
population is the:
1. mortality rate
2. mortality ratio
3. standard deviation
4. confidence interval
Answer: 2. Mortality ratios indicate the relative risk of individuals in a
group, defining how much mortality risk there is for that specific group
compared to the mortality risk of the reference population.
