Test Questions from Boot Camp
When taking a patient’s history prior to intravenous (IV) contrast injection,
what factors are NOT a consideration for contraindication?
a. Renal insufficiency
b. Personal history of asthma
c. Sensitivity of Aspirin
d. Previous reaction to contrast media
c. Sensitivity of Aspirin
Explanation of the Correct Option
• c. Sensitivity of Aspirin: A patient's sensitivity or allergy to aspirin does not
correlate with an increased risk of a reaction to intravenous (IV) iodinated
contrast media. It is not considered a valid risk factor or contraindication
during pre-injection screening. [1]
Explanation of the Incorrect Options
• ❌ a. Renal insufficiency: This is a critical consideration because impaired
kidney function places the patient at high risk for contrast-induced
nephropathy (CIN) or post-contrast acute kidney injury. [1, 2, 3, 4]
• ❌ b. Personal history of asthma: Individuals with a medical history of
asthma are statistically more likely to experience a severe, acute
hypersensitivity or anaphylactoid reaction to contrast media. [1, 2]
• ❌ d. Previous reaction to contrast media: A prior adverse reaction to the
same class of contrast material is the single greatest predisposing risk factor
and serves as a significant relative contraindication
Which of the following contrast agents, when added to the body, decreases
the tissue density of the body part?
, Page 2 of 171
a. Carbon dioxide
b. Gastrografin
c. Barium sulfate
d. Omnipaque
a. Carbon dioxide
Explanation of the Correct Option
• a. Carbon dioxide: Carbon dioxide (\(CO_{2}\)) is classified as a negative
contrast agent. Because it is a gas, it has a low atomic number and low
physical density. When introduced into a body part or organ lumen, it
decreases the overall tissue density of that area, making it more radiolucent
(appearing darker or black on an X-ray or CT image). [1, 2, 3, 4]
Explanation of the Incorrect Options
• ❌ b. Gastrografin: This is a water-soluble, iodinated positive contrast
agent. Iodine has a high atomic number, which increases tissue density and
X-ray absorption (appearing bright white). [1, 2, 3]
• ❌ c. Barium sulfate: This is an insoluble positive contrast agent used
heavily for gastrointestinal imaging. Barium has a high atomic number and
increases the density of the organ. [1, 2, 3, 4]
• ❌ d. Omnipaque: This is a non-ionic, iodinated positive contrast agent
used for intravascular and intrathecal injections. Like other iodinated agents, it
increases tissue density to block X-rays
Epistaxis is the term used to describe:
a. Nosebleeds
b. Difficulty breathing
c. Hives
d. Reddening of the skin
a. Nosebleeds
Explanation of the Correct Option
• a. Nosebleeds: Epistaxis is the definitive medical term for a nosebleed. It
occurs when the fragile, superficial blood vessels lining the inside of the nasal
cavity rupture, causing blood to flow from one or both nostrils. [1, 2]
Explanation of the Incorrect Options
• b. Difficulty breathing: This symptom is medically referred to as
dyspnea.
• c. Hives: This itchy, raised skin rash is medically referred to as urticaria.
• d. Reddening of the skin: This condition is medically referred to as
erythema

A very serious and life-threatening response to an injection of contrast
medium is called:
a. Hypoglycemia
b. Anaphylaxis
c. Urticaria
d. Hypovolemic shock
b. Anaphylaxis
Explanation of the Correct Option
• b. Anaphylaxis: This is a severe, systemic hypersensitivity reaction that can
develop within seconds or minutes of a contrast medium injection. It causes a
massive release of histamine, leading to life-threatening complications like
airway obstruction (bronchospasm/laryngeal oedema), severe hypotension,
and circulatory collapse. [1, 2, 3, 4]
Explanation of the Incorrect Options
• ❌ a. Hypoglycemia: This term refers to abnormally low blood sugar levels,
which is a metabolic condition typically related to diabetes management rather
than an acute reaction to contrast media. [1, 2, 3]
• ❌ c. Urticaria: Commonly known as hives, urticaria represents a mild to
moderate localized cutaneous reaction. While it can be a symptom of a larger
anaphylactic response, isolated hives are not inherently life-threatening. [1, 2,
3, 4, 5]
• ❌ d. Hypovolemic shock: This form of shock is caused by a severe loss of
blood or body fluids (such as from trauma or severe dehydration). It is not a
direct pathological response triggered by contrast media administration
Streptococcus is a type of:
a. Virus
b. Bacteria
c. Protozoa
d. Fungi
b. Bacteria
Explanation of the Correct Option
• b. Bacteria: Streptococcus is a well-documented genus of spherical, Gram-
positive bacteria. They typically arrange themselves in pairs or characteristic
twisted chains and are responsible for common human illnesses like strep
throat, scarlet fever, and certain types of pneumonia. [1, 2, 3, 4]
Explanation of the Incorrect Options
, Page 4 of 171
• ❌ a. Virus: Viruses are submicroscopic, non-cellular infectious agents that
require a host cell to replicate. They are entirely distinct from cellular
organisms like Streptococcus.
• ❌ c. Protozoa: Protozoa are single-celled eukaryotic organisms (possessing
a membrane-bound nucleus and organelles), whereas Streptococcus species
are prokaryotes.
• ❌ d. Fungi: Fungi are eukaryotic organisms that include yeasts, molds, and
mushrooms. They possess chitin in their cell walls, unlike the peptidoglycan
cell walls found in Streptococcus bacteria.
The drug Nitroglycerin is indicated for the treatment of which two of the
following? (select 2)
a. Stroke
b. Heart attack
c. Angina
d. Hives
b. Heart attack
c. Angina
The technologist must use strict infection-control measures that include blood
and body fluid precautions:
a. For every patient
b. For patients who have known communicable disease
c. Only for patients who have acquired immunodeficiency syndrome (AIDS) or
hepatitis B
d. For patients who seem ill
a. For every patient
In an unwitnessed cardiac arrest, the first five seconds of rescue activity is
used to:
a. Palpate for a carotid pulse
b. Open the airway
c. Call a code
d. Establish unresponsiveness
d. Establish unresponsiveness
