Free Computed Tomography Trivia Questions and Answers

Question 1

For an adult, the usual range of respiration is

Accepted Answer

12-20 breaths per minute

Answer

A CT scout image, also known as a topogram or pilot scan, is a preliminary low-dose X-ray image taken before the main CT scan. While primarily used to plan the scan range and ensure proper patient positioning, it can also be utilized for specific measurements, including bone density in certain clinical contexts. It helps the technologist define the exact area to be scanned and optimize parameters.

Question 2

A patient having a history of an allergic reaction to iodinated contrast media may undergo the following procedures in advance of a contrast-enhanced CT scan:

Accepted Answer

Premedication with steroids and antihistamines

Answer

For an adult, the normal range of respiration is typically 12-20 breaths per minute. This rate can vary slightly based on activity level, age, and individual health status. Monitoring respiration rate is a standard vital sign assessment, providing insight into a patient's respiratory function and overall physiological state.

Question 3

Which of the following signs may a patient in shock display?

Accepted Answer

All of the above

Answer

Shock is a critical condition characterized by inadequate tissue perfusion, leading to a systemic response. Tachycardia (rapid heart rate) is a compensatory mechanism to maintain cardiac output, while rapid, shallow breathing attempts to increase oxygen intake. Cyanosis (bluish discoloration of the skin) indicates poor oxygenation due to insufficient blood flow. Therefore, all these signs are commonly displayed by a patient in shock.

Question 4

Which of the following signs may a patient in shock display? Which infection control measures are necessary at the site of an intravenous injection of iodinated contrast media?

Accepted Answer

Surgical asepsis

Answer

An intravenous injection involves penetrating the skin barrier and directly accessing the bloodstream. To prevent the introduction of microorganisms and subsequent infection, a sterile technique is absolutely essential. Surgical asepsis, also known as sterile technique, aims to eliminate all microorganisms from an area and is the appropriate measure for any procedure that invades sterile body tissues or the circulatory system.

Question 5

Iodinated contrast material is frequently injected intravenously at the following sites:

Accepted Answer

All of the above

Answer

The antecubital, cephalic, and basilic veins are all commonly used and accessible sites for intravenous injections, including the administration of iodinated contrast material. The antecubital vein, located in the bend of the elbow, is often preferred due to its size and superficial location. The cephalic and basilic veins, running along the forearm, also provide suitable and frequently utilized access points for venipuncture.
