ALU 101 - COMPLETE MOCK EXAM #2
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 magnetic field to induce
changes in proton spin within tissues is:
1. computed tomography
2. positron emission tomography
3. magnetic resonance imaging
4. fluoroscopy
Answer: 3. Magnetic resonance imaging (MRI) uses a magnetic field to
induce changes in proton spin within tissues. Radio waves are emitted at
specific frequencies that make atoms resonate and absorb energy, then
tissues release a weak radio wave that can be measured.
2. The type of endoscopic procedure used to visualize the trachea
and bronchi is:
, 1. colonoscopy
2. bronchoscopy
3. gastroscopy
4. laparoscopy
Answer: 2. Bronchoscopy permits visualization of the trachea and vocal
cords, as well as the main bronchial tubes and smaller branches. It allows
biopsy of tissue by bronchial washing, brushing, or direct tissue removal.
3. The test that measures intraocular pressure to screen for
glaucoma is:
1. Snellen test
2. fluorescein angiography
3. tonometry
4. Schirmer tear test
Answer: 3. Tonometry measures intraocular pressure. Non-contact
tonometry uses an air puff to gently flatten the cornea and is often used
to screen for glaucoma.
4. The laboratory test that measures the average blood glucose
level over the prior 120-day period is:
1. fructosamine
2. fasting blood glucose
3. hemoglobin A1c
4. glucose tolerance test
Answer: 3. Hemoglobin A1c measures the amount of glucose bound to
hemoglobin in red blood cells. Since red blood cells have a half-life of
about 120 days, A1c represents the average glucose concentration over
that period.
5. The condition in which an individual has blood sugar levels
higher than normal but not high enough for diabetes diagnosis is:
1. metabolic syndrome
, 2. hyperglycemic crisis
3. pre-diabetes
4. insulin resistance
Answer: 3. Pre-diabetes includes impaired fasting glucose (IFG) and
impaired glucose tolerance (IGT). These individuals have an increased risk
of developing type 2 diabetes.
6. The minimum pressure occurring at the end of the relaxation
phase of the heartbeat is:
1. systolic blood pressure
2. pulse pressure
3. diastolic blood pressure
4. mean arterial pressure
Answer: 3. Diastolic blood pressure is the minimum pressure occurring at
the end of diastole, the relaxation phase of the heartbeat.
7. The term for abnormal type of excessive cell proliferation
characterized by loss of normal tissue arrangement and cell
structure is:
1. hyperplasia
2. metaplasia
3. dysplasia
4. anaplasia
Answer: 3. Dysplasia is an abnormal type of excessive cell proliferation
characterized by loss of normal tissue arrangement and cell structure. It
can be described as mild to severe.
8. The presence of protein in urine greater than 150 mg/day is
called:
1. hematuria
2. glycosuria
3. proteinuria
, 4. ketonuria
Answer: 3. Proteinuria is the presence of protein in urine greater than
150 mg/day and is associated with excess mortality because of likely
kidney impairment or damage.
9. According to the NHTSA, the number of fatalities per 100
million vehicle miles traveled in 2022 was less than:
1. 0.5
2. 1.35
3. 2.5
4. 5.0
Answer: 2. Over the past four decades, deaths have declined steadily
from over 5 fatalities/100 million miles in 1968 to less than 1.35/100
million miles in 2022.
10. The measure of how well a laboratory test excludes the
possibility of a particular disease or abnormal health condition is:
1. sensitivity
2. specificity
3. reliability
4. accuracy
Answer: 2. Specificity is the measure of how well the test excludes the
possibility of a particular disease or abnormal health condition (i.e.,
identify true negatives).
11. The imaging study that uses a contrast material injected
directly into the coronary arteries to determine the site and
extent of obstruction is:
1. coronary CT angiography
2. myocardial perfusion scan
3. coronary angiography
4. electron beam computed tomography
