A CT Scan can be used to detect colorectal cancer

True
False

Correct Answer

A. True

Explanation

A CT scan, also known as a computed tomography scan, is a medical imaging procedure that uses multiple X-ray images to create detailed cross-sectional images of the body. It can be used to detect colorectal cancer by providing a clear view of the colon and rectum, allowing doctors to identify any abnormalities or tumors. This imaging technique is often used alongside other diagnostic tests to confirm the presence of colorectal cancer and determine its stage and extent. Therefore, the statement "A CT Scan can be used to detect colorectal cancer" is true.

A Tox Screen can be taken through a ____________

Correct Answer
Blood Test
Stool Sample
Urine Sample

Explanation
A Tox Screen can be taken through a blood test, stool sample, or urine sample. These methods are used to detect the presence of toxins or drugs in the body. A blood test involves drawing a sample of blood from a vein, while a stool sample involves collecting a small amount of feces for analysis. A urine sample requires providing a sample of urine, which can be collected in a container. All three methods can be used to screen for toxins and drugs in the body.

Tick all that can be diagnosed through taking a Tox Screen.

Dementia
Aortic Stenosis
Alcoholism
Overdosage
Benign Tumours
Hemihepatectomy

Correct Answer(s)

A. Dementia
A. Alcoholism
A. Overdosage

Explanation

A Tox Screen is a test that can detect the presence of drugs or toxins in a person's system. Dementia, alcoholism, and overdosage can all be diagnosed through a Tox Screen because they can be associated with the use or abuse of certain substances. However, Aortic Stenosis, Benign Tumors, and Hemihepatectomy cannot be diagnosed through a Tox Screen as they are medical conditions that are not directly related to drug or toxin use.

What does an MRI scan use?

Radiation
Magnetism
Sound

Correct Answer

A. Magnetism

Explanation

An MRI scan uses magnetism to create detailed images of the body's internal structures. During the scan, the patient is placed inside a large magnet, which causes the hydrogen atoms in the body to align in a certain way. Radio waves are then used to disrupt this alignment, and as the atoms return to their original position, they emit signals that are detected by the MRI machine. These signals are then processed to generate the images. Unlike other imaging techniques such as X-rays, MRI scans do not use radiation, making them safer for patients.

An MRI scan can distinguish between different ____________ in the body

Correct Answer
soft tissue
soft tissues
soft matter

Explanation
An MRI scan is a medical imaging technique that uses magnetic fields and radio waves to create detailed images of the body's internal structures. It is particularly effective in distinguishing between different types of soft tissue, such as muscles, organs, and tumors. By analyzing the varying signals emitted by different types of soft tissue, an MRI scan can provide valuable information for diagnosing and monitoring various medical conditions. Soft tissues refer to the pliable and non-bony parts of the body, and soft matter is a broader term that includes both soft tissues and other substances like liquids or gels.

Tick all an LFT (liver function test) can do

Find different liver disorders
How damaged the liver is
The blood content in the liver
How many hormones are in the liver
Check if the patient has chronic liver disease

Correct Answer(s)

A. Find different liver disorders
A. How damaged the liver is
A. Check if the patient has chronic liver disease

Explanation

An LFT (liver function test) can be used to find different liver disorders by measuring the levels of certain enzymes and proteins in the blood that indicate liver damage or dysfunction. It can also provide information on how damaged the liver is by assessing the levels of bilirubin, a waste product produced by the liver. Additionally, an LFT can help in checking if the patient has chronic liver disease by evaluating the levels of certain liver enzymes and proteins over a period of time.

In a colonoscopy, what is the end of the camera coated in?

Lidocaine
Propofol
Salbutomol

Correct Answer

A. Lidocaine

Explanation

In a colonoscopy, the end of the camera is coated in lidocaine. Lidocaine is a local anesthetic that is commonly used to numb the area and reduce discomfort during medical procedures. Coating the camera with lidocaine helps to minimize any potential pain or discomfort that the patient may experience during the colonoscopy.

Tick the procedure used to remove an appendix

Appendeceptomy
Appendectomy
Appendoplasty

Correct Answer

A. Appendectomy

Explanation

An appendectomy is the correct procedure used to remove an appendix. This surgical procedure involves the removal of the appendix, which is a small pouch-like organ located in the lower right side of the abdomen. An appendectomy is typically performed to treat appendicitis, which is the inflammation of the appendix. During the procedure, the surgeon makes a small incision in the abdomen and removes the appendix. This is the most common and effective method for treating appendicitis.
