Questions and Answers
- 1.
Which of the following symptoms indicate a vagal reaction to Contrast 1. Bradycardia 2.A systolic pressure of less than 80 mm Hg 3. Diastolic pressure of more than 90 mm Hg
- A.
1 only
- B.
3 only
- C.
1 and 2
- D.
1 and 3
Correct Answer
C. 1 and 2Explanation
Bradycardia and a systolic pressure of less than 80 mm Hg are symptoms that indicate a vagal reaction to Contrast. Vagal reactions are caused by stimulation of the vagus nerve, which can lead to a decrease in heart rate (bradycardia) and a decrease in blood pressure (systolic pressure less than 80 mm Hg). These symptoms can occur in response to the administration of contrast agents during medical procedures. Diastolic pressure of more than 90 mm Hg is not a symptom of a vagal reaction and therefore not included in the correct answer.Rate this question:

- A.
A statement releasing the health professional involved from any and all responsibility
- B.
A clause protecting the Tech from possible lawsuit or negligence
- C.
An explanation of the procedure with its accompanying risks and possible alternatives
- D.
All of the above
Correct Answer
C. An explanation of the procedure with its accompanying risks and possible alternativesExplanation
The correct answer is "an explanation of the procedure with its accompanying risks and possible alternatives." This is because a PT consent form for a CT scan with IV contrast should include a clear explanation of the procedure, including any associated risks and possible alternatives. This is important for informed consent, ensuring that the patient understands what the procedure entails and the potential outcomes. The other options, such as releasing the health professional from responsibility or protecting the Tech from lawsuits, are not necessary components of a consent form and may not be ethically appropriate.Rate this question:

Which of the following is an advantage of non-ionic contrast?
- A.
Decreased cost
- B.
Decreased nephrotoxicity
- C.
Decreased enhancment
- D.
Decreased incidence of adverse reaction
Correct Answer
D. Decreased incidence of adverse reactionExplanation
Non-ionic contrast agents have a decreased incidence of adverse reactions compared to ionic contrast agents. This is because non-ionic contrast agents have a lower osmolality, meaning they have a lower concentration of particles that can cause adverse reactions. This makes them safer to use, especially in patients with pre-existing renal impairment or those who are at a higher risk of adverse reactions.Rate this question:

Radiation exposure and its potentially harmful effects have a relationship that is termed
- A.
Stochastic
- B.
Nonstochastic
- C.
Negligible
- D.
None of the above
Correct Answer
A. StochasticExplanation
The term "stochastic" refers to a random or chance occurrence. In the context of radiation exposure and its effects, the term stochastic is used to describe the relationship between exposure and the likelihood of harmful effects. Stochastic effects are those that occur randomly and have a probability of happening, such as the development of cancer. Nonstochastic effects, on the other hand, have a threshold level of exposure below which no harm is expected. The term "negligible" implies that the effects of radiation exposure are insignificant, which is not true. Therefore, the correct answer is "stochastic" as it accurately describes the relationship between radiation exposure and its potentially harmful effects.Rate this question:

Intrathecal injection of Contrast may be performed for which of the following CT exams
- A.
Knee
- B.
Pituitary
- C.
Lumbar spine
- D.
High resolution chest
Correct Answer
C. Lumbar spineExplanation
An intrathecal injection of contrast is performed for CT exams of the lumbar spine. This procedure involves injecting contrast directly into the space around the spinal cord, known as the intrathecal space. By doing so, the contrast can better visualize the spinal cord and surrounding structures, helping to diagnose conditions such as spinal tumors, herniated discs, or spinal infections. The other options listed (knee, pituitary, high resolution chest) do not typically require an intrathecal injection of contrast for imaging purposes.Rate this question:

Which of the following lab values are the most dependable measures of renal function?
- A.
BUN
- B.
Creatinine
- C.
PT
- D.
PTT
Correct Answer
B. CreatinineExplanation
Creatinine is the most dependable measure of renal function because it is a waste product produced by muscles and filtered out of the blood by the kidneys. Elevated levels of creatinine indicate impaired kidney function, as the kidneys are not effectively filtering it out. BUN (blood urea nitrogen) is also used to assess renal function, but it can be influenced by factors such as diet and hydration status, making creatinine a more reliable indicator. PT (prothrombin time) and PTT (partial thromboplastin time) are tests used to assess blood clotting and are not directly related to renal function.Rate this question:

- B.
60-90 mmHG
- C.
80-120 mmHG
- D.
95-140 mmHG
Correct Answer
B. 60-90 mmHGExplanation
The diastolic blood pressure represents the pressure in the arteries when the heart is at rest between beats. A normal range for diastolic blood pressure in an adult is typically between 60-90 mmHg. This range indicates that the blood vessels are able to relax and fill with blood properly, allowing for adequate blood flow throughout the body. Values below or above this range may indicate underlying health conditions or cardiovascular problems.Rate this question:

PT preparation for CT of A/P may include which of the following 1. Receiving nothing by mouth for 4 hours before the exam 2.Digestion of a fatty meal 1 hour before the exam 3. Refraining from urination for 2 hours before the exam
- A.
1 only
- B.
2 only
- C.
1 and 3
- D.
1, 2, and 3
Correct Answer
A. 1 onlyExplanation
The correct answer is "1 only" because it is common practice to instruct patients to fast for a certain number of hours before a CT scan of the abdomen and pelvis. This is done to ensure that the digestive system is empty, allowing for better visualization of the organs and structures in the area. Digestion of a fatty meal (option 2) would not be recommended as it could interfere with the quality of the images. Refraining from urination (option 3) is not necessary for a CT scan of the abdomen and pelvis.Rate this question:

Which of the following types of oral contrast could cause peritonitis if leakage from the digestive tract occurs due to perforation?
- A.
Gastrographin
- B.
Barium sulfate
- C.
Hypaque
- D.
Effervescent granules
Correct Answer
B. Barium sulfateExplanation
Barium sulfate is a type of oral contrast used in medical imaging to enhance the visibility of the digestive tract. If there is a perforation in the digestive tract, leakage of barium sulfate could lead to peritonitis, which is inflammation of the peritoneum, the lining of the abdominal cavity. This can occur because barium sulfate is not absorbed by the body and can cause irritation and infection if it leaks into the peritoneum. Therefore, barium sulfate is the type of oral contrast that could cause peritonitis in the event of a perforation.Rate this question:

The reduction in number of infectious organisms w/o a complete elimination is termed
- A.
Medical asepsis
- B.
Sterilization
- C.
Surgical asepsis
- D.
Immunization
Correct Answer
A. Medical asepsisExplanation
Medical asepsis refers to the reduction in the number of infectious organisms without completely eliminating them. It involves practices such as hand hygiene, proper cleaning and disinfection of surfaces, and using personal protective equipment to prevent the spread of infection. Unlike sterilization, which completely eliminates all microorganisms, medical asepsis focuses on reducing the number of pathogens to a level that is not harmful to individuals. Surgical asepsis, on the other hand, refers to the complete elimination of all microorganisms in a specific area during surgical procedures. Immunization, on the other hand, is the process of inducing immunity to a specific disease through vaccination.Rate this question:
