PART I: STRAIGHT ANSWER QUESTIONS (1-45)
1. The imaging modality that uses a continuous x-ray beam to visualize
moving structures in real time is:
1. computed tomography
2. magnetic resonance imaging
3. fluoroscopy
4. ultrasonography
Answer: 3. Fluoroscopy is an imaging tool that allows the physician to view, in
real time, moving parts of the body, such as barium moving through the
intestine. It involves a continuous x-ray beam.
2. The procedure that involves radiographic imaging of the
subarachnoid spaces containing spinal fluid to diagnose CSF problems
is called:
1. cisternography
2. myelography
3. ventriculography
4. pneumoencephalography
Answer: 1. Cisternography is the radiographic imaging of the subarachnoid
spaces that contain spinal fluid (cisterns). It is used to diagnose cerebral spinal
fluid problems such as normal pressure hydrocephalus or spinal fluid fistulas.
3. The test that measures the time it takes for an ingested meal
containing a radioactive isotope to pass out of the stomach is called:
1. gastric emptying study
, 2. reflux testing
3. cholescintigraphy
4. small bowel follow-through
Answer: 1. Gastric emptying is the time it takes for an ingested meal containing
a small amount of radioactive isotope to pass out of the stomach. It is indicated
for diagnosis of gastric outlet obstruction and gastroparesis.
4. The term for the presence of an anticoagulant in a blood sample tube
to prevent clotting is:
1. serum separator
2. clot activator
3. anticoagulant
4. preservative
Answer: 3. Blood samples include whole blood collected into a tube containing
an anticoagulant (an agent to stop the blood from clotting) and a serum tube in
which blood is allowed to clot.
5. The condition in which an individual has blood sugar levels that are
higher than normal but not high enough for diabetes diagnosis,
specifically measured two hours after a glucose load, is called:
1. impaired fasting glucose
2. impaired glucose tolerance
3. metabolic syndrome
4. insulin resistance
Answer: 2. Impaired glucose tolerance (IGT) is diagnosed when the two-hour
blood glucose level on an oral glucose tolerance test is between 140-199 mg/dl.
Normal is <140, diabetes is ≥200.
6. The type of hypertension that is inaccurately high in the elderly due
to stiff, calcified arteries is called:
1. systolic hypertension
2. white coat hypertension
3. pseudo-hypertension
4. resistant hypertension
,Answer: 3. Pseudo-hypertension refers to inaccurately high readings in the
elderly due to stiff, calcified arteries or in the obese due to a BP cuff that is too
small.
7. The term for the alteration of normal cells to a different cell type,
often in response to chronic irritation or inflammation, is:
1. hyperplasia
2. hypertrophy
3. metaplasia
4. dysplasia
Answer: 3. Metaplasia is the reversible replacement of one differentiated cell
type with another mature differentiated cell type, often in response to chronic
irritation or inflammation.
8. The test that measures the protein produced by the liver that is
decreased in starvation, cirrhosis, and cancer-related wasting is:
1. globulin
2. albumin
3. total protein
4. prealbumin
Answer: 2. Albumin, produced in the liver, is the most abundant protein in
blood. Albumin is decreased in starvation, cirrhosis, and in the weight loss
(wasting or cachexia) that often accompanies cancer or HIV.
9. The term for a court-mandated breathalyzer connected to the
ignition of a motor vehicle that prevents starting if alcohol is detected
is:
1. administrative per se device
2. ignition interlock device
3. alcohol monitoring system
4. passive alcohol sensor
Answer: 2. The interlock device is a court-mandated breathalyzer connected to
the ignition. It prevents the engine from starting if it detects a blood alcohol
content above the legal limit, typically 0.02-0.04%.
10. The statistical term for the range that includes 95% of test results
from a healthy population is the:
, 1. standard deviation
2. confidence interval
3. reference range
4. mortality ratio
Answer: 3. The reference range (normal or expected range) for a test is
determined by analyzing test values from a large group of healthy people. This
range usually includes 95% of the population.
11. The cardiac test that uses a catheter threaded from the femoral
vein into the right heart to stimulate various parts and induce
arrhythmias under controlled circumstances is:
1. electrophysiological mapping
2. coronary angiography
3. intracardiac echocardiography
4. fractional flow reserve
Answer: 1. Electrophysiological (EP) mapping is done to assess significant
arrhythmias. The cardiologist threads a catheter into the right heart and
stimulates various parts to induce cardiac arrhythmias under controlled
circumstances.
12. The type of stress testing that uses drugs to stress the heart when
the patient cannot exercise is called:
1. exercise tolerance test
2. pharmacologic stress test
3. ambulatory stress test
4. provocative stress test
Answer: 2. Pharmacologic stress testing is performed when the patient is
unable to exercise. Drugs such as adenosine, regadenoson, and dobutamine are
used to stress the heart, combined with imaging.
13. The legal term for damages awarded to a plaintiff to punish the
defendant is:
1. compensatory damages
2. punitive damages
3. liquidated damages
4. nominal damages
