ARRT Computed Tomography - Test Reviews Sample Questions

What type of catheter is also referred to as a condom catheter?

Correct Answer:
external catheter.


the type of catheter that is also referred to as a condom catheter is the external catheter.

external catheters, unlike other types of urinary catheters, are designed for external use. they are typically used by individuals who have urinary incontinence but do not have urinary retention issues that require internal catheterization. this type of catheter gets its informal name, "condom catheter," from its design and method of application. it resembles a condom in that it covers the external genitalia (specifically, the penis in males) and is held in place similarly. the external catheter is connected to a drainage bag, which collects the urine as it is expelled naturally from the bladder.

external catheters are made from a variety of materials including latex, silicone, or rubber, providing flexibility and comfort to the user. they are favored in situations where the patient prefers a non-invasive option, or where long-term use of catheters is necessary but internal catheterization is not ideal due to the risk of infections such as urinary tract infections (utis).

these catheters are particularly beneficial for patients with good bladder control but poor urethral control, neurological disorders affecting bladder control, or for those who are bedridden or in a coma. the use of external catheters can significantly improve the quality of life for patients with such conditions, providing them with a safer and more dignified way to manage urinary incontinence.

it is important to note that while external (condom) catheters can reduce the risk of certain complications associated with internal catheters, such as utis, they need to be changed daily to maintain hygiene and prevent other potential issues like skin irritation or breakdown. proper sizing and fit are crucial to ensure effectiveness and minimize any discomfort or complications.

When something unrelated to the anatomical subject appears on the CT image, it would be referred to which of the following?

Correct Answer:
artifact
when something unrelated to the anatomical subject appears on a ct image, the correct term to describe this phenomenon is "artifact."

artifacts on ct images are essentially visual anomalies or distortions that do not correspond to actual physical structures within the scanned body. these can arise due to various factors, including but not limited to patient movement, technical issues with the ct equipment, or even external interference. for example, if a patient moves during the scanning process, it could lead to blurring or streaks that appear on the final image. similarly, metal objects, such as dental fillings or surgical implants, can cause streaking and shadows due to their high density compared to surrounding tissues.

it is crucial for medical imaging technologists and radiologists to recognize and identify artifacts accurately. this knowledge helps in differentiating these from true anatomical or pathological findings, ensuring that diagnoses are based on correct interpretations of the ct images. misinterpretation of artifacts as genuine anatomical structures can lead to incorrect diagnoses and potentially harmful treatment decisions.

techniques and strategies to minimize the occurrence of artifacts include proper patient preparation and positioning, optimal setting of scanning parameters, and the use of advanced image processing software that can help filter out some types of artifacts. additionally, ongoing training and education for technologists and interpreting radiologists about different types of artifacts and their causes are crucial in improving the accuracy of ct imaging.
