The correct answer is provided directly below each question.
PART I: STRAIGHT ANSWER QUESTIONS (1-45)
1. The imaging technique that uses small amounts of a short-lived
radioactive substance formulated to be absorbed by targeted
tissues is:
1. magnetic resonance imaging
2. computed tomography
3. nuclear medicine
4. ultrasonography
Answer: 3. Nuclear medicine involves the use of small amounts of a
short-lived radioactive substance (radioisotope) that is formulated to be
absorbed by targeted tissues. A radionuclide can be attached to a carrier
substance and injected, taken orally, or inhaled.
,2. The endoscopic procedure that allows visualization of the
larynx and vocal cords is:
1. bronchoscopy
2. laryngoscopy
3. mediastinoscopy
4. thoracoscopy
Answer: 2. Laryngoscopy can be done indirectly with a handheld mirror
or directly using a flexible laryngoscope inserted through the nose or
mouth to visualize the pharynx, larynx, and vocal cords.
3. The test that measures the electrical activity produced by the
brain and records alpha, beta, delta, and theta waves is:
1. electromyography
2. evoked potentials
3. electroencephalography
4. transcranial doppler
Answer: 3. Electroencephalography (EEG) measures and records the low
voltage electrical activity produced by the brain. Electrodes are placed on
the scalp, and the recordings show standard patterns of alpha, beta, delta,
and theta waves.
4. The term for the presence of high concentrations of lipid in
serum that can transform clear straw-colored serum to milky
white is:
1. hemolysis
2. lipemia
3. glycolysis
4. turbidity
Answer: 2. Lipemia is the presence of high concentrations of lipid (fats)
in serum. Lipemic serum has a characteristic color that, in severe cases,
transforms the clear straw-colored serum to milky white.
,5. The type of diabetes that develops in some females during
pregnancy and generally resolves after delivery is:
1. type 1 diabetes
2. type 2 diabetes
3. gestational diabetes
4. LADA
Answer: 3. Gestational diabetes mellitus (GDM) is a form of diabetes that
develops in some females during pregnancy and generally resolves after
delivery. It affects approximately 2-10% of pregnancies.
6. The condition in which an individual has a sustained elevation
in systolic BP above 140 mmHg or diastolic BP above 90 mmHg is
called:
1. hypotension
2. hypertension
3. labile BP
4. white coat hypertension
Answer: 2. Hypertension is generally defined as a sustained elevation in
systolic BP above 140 mmHg or in diastolic BP above 90 mmHg. It is the
most common reason for physician visits.
7. The term for a group of abnormal cells considered to be either
a noninvasive cancer or a pre-cancerous condition is:
1. dysplasia
2. metaplasia
3. carcinoma in situ
4. hyperplasia
Answer: 3. Carcinoma in situ is a group of abnormal cells considered to
be either a noninvasive cancer or a pre-cancerous condition. Many types
have a high probability of progression to invasive cancer.
, 8. The test that measures the estimated glomerular filtration rate
using serum creatinine, age, and gender is:
1. BUN
2. cystatin C
3. eGFR
4. creatinine clearance
Answer: 3. Estimated glomerular filtration rate (eGFR) is calculated using
serum creatinine and the individual's age and gender. The lower limit of
normal is generally 60 ml/min/1.73m².
9. The term for driving under the influence of any drug that can
impair motor skills, reaction time, and judgment is:
1. DUI
2. drugged driving
3. administrative per se
4. zero tolerance
Answer: 2. Drugged driving is driving under the influence of any drug
that can impair motor skills, reaction time, and judgment. Drugs are used
by approximately 10-22% of drivers involved in crashes.
10. The type of error that occurs when a positive test result is
caused by a transient health condition and does not reflect a true
disease state is called a:
1. false positive
2. false negative
3. true positive
4. true negative
Answer: 1. A false positive occurs when a positive test result is caused
by a transient health condition or physical variation so that the result does
not reflect a true state of disease or abnormal health.
