Which imaging technique utilizes magnetic fields and radio waves to produce detailed images of internal body structures?

  1. X-ray

  2. Ultrasound

  3. Magnetic Resonance Imaging (MRI)

  4. Computed Tomography (CT) scan


Correct Option: C
Explanation:

MRI employs magnetic fields and radio waves to generate cross-sectional images of organs and tissues, providing intricate anatomical and physiological details.

What is the primary role of a pathologist in the diagnosis of diseases?

  1. Performing surgeries

  2. Prescribing medications

  3. Examining tissue samples under a microscope

  4. Conducting patient interviews


Correct Option: C
Explanation:

Pathologists analyze tissue samples under a microscope to identify abnormalities that may indicate the presence of a disease or condition.

Which diagnostic technique involves the introduction of a small camera into the body through a natural orifice or incision?

  1. Biopsy

  2. Endoscopy

  3. X-ray

  4. Ultrasound


Correct Option: B
Explanation:

Endoscopy allows visualization of the internal organs and tissues using a small camera attached to a flexible tube inserted into the body.

What is the term for the process of removing a tissue sample from the body for examination?

  1. Biopsy

  2. Autopsy

  3. Excision

  4. Debridement


Correct Option: A
Explanation:

Biopsy involves the removal of a small tissue sample from the body for microscopic examination to aid in the diagnosis of diseases.

Which treatment modality utilizes high-energy radiation to target and destroy cancerous cells?

  1. Chemotherapy

  2. Radiation therapy

  3. Surgery

  4. Immunotherapy


Correct Option: B
Explanation:

Radiation therapy employs high-energy radiation to precisely target and eliminate cancerous cells while minimizing harm to surrounding healthy tissues.

What is the term for the surgical removal of a diseased or damaged organ or tissue?

  1. Biopsy

  2. Excision

  3. Debridement

  4. Ligation


Correct Option: B
Explanation:

Excision involves the surgical removal of a diseased or damaged organ or tissue to prevent further complications or spread of the disease.

Which treatment approach utilizes the body's immune system to recognize and attack cancer cells?

  1. Chemotherapy

  2. Radiation therapy

  3. Surgery

  4. Immunotherapy


Correct Option: D
Explanation:

Immunotherapy harnesses the body's immune system to identify and target cancer cells, stimulating an immune response to eliminate them.

What is the term for the use of drugs to treat or prevent diseases?

  1. Chemotherapy

  2. Radiation therapy

  3. Surgery

  4. Pharmacotherapy


Correct Option: D
Explanation:

Pharmacotherapy involves the administration of drugs to treat or prevent diseases by targeting specific biological processes or pathways.

Which treatment modality involves the use of heat to destroy cancerous tissues?

  1. Cryotherapy

  2. Hyperthermia

  3. Radiofrequency ablation

  4. Microwave ablation


Correct Option: B
Explanation:

Hyperthermia utilizes heat to destroy cancerous tissues by raising their temperature above a critical threshold, causing cell death.

What is the term for the surgical removal of a portion of an organ or tissue to treat a disease or condition?

  1. Biopsy

  2. Excision

  3. Resection

  4. Debridement


Correct Option: C
Explanation:

Resection involves the surgical removal of a portion of an organ or tissue to eliminate diseased or damaged tissue and restore normal function.

Which treatment approach utilizes targeted drugs to inhibit the growth and spread of cancer cells?

  1. Chemotherapy

  2. Radiation therapy

  3. Targeted therapy

  4. Immunotherapy


Correct Option: C
Explanation:

Targeted therapy employs drugs that specifically target molecules or proteins involved in cancer cell growth and survival, inhibiting their activity to halt tumor progression.

What is the term for the use of cold temperatures to destroy cancerous tissues?

  1. Cryotherapy

  2. Hyperthermia

  3. Radiofrequency ablation

  4. Microwave ablation


Correct Option: A
Explanation:

Cryotherapy utilizes extremely low temperatures to freeze and destroy cancerous tissues, causing cell death.

Which treatment modality involves the use of high-frequency sound waves to generate heat and destroy cancerous tissues?

  1. Cryotherapy

  2. Hyperthermia

  3. Radiofrequency ablation

  4. Microwave ablation


Correct Option: C
Explanation:

Radiofrequency ablation employs high-frequency sound waves to generate heat and destroy cancerous tissues by causing cell death.

What is the term for the surgical creation of an artificial opening in the body to allow the drainage of fluids or waste?

  1. Biopsy

  2. Excision

  3. Fistula

  4. Stoma


Correct Option: D
Explanation:

A stoma is an artificially created opening in the body, often in the abdomen, to allow the drainage of fluids or waste from an internal organ.

Which treatment approach utilizes genetic engineering techniques to modify immune cells to target and destroy cancer cells?

  1. Chemotherapy

  2. Radiation therapy

  3. Targeted therapy

  4. CAR T-cell therapy


Correct Option: D
Explanation:

CAR T-cell therapy involves genetically modifying a patient's own T cells to express chimeric antigen receptors (CARs) that recognize and target specific antigens on cancer cells, enabling the T cells to effectively eliminate the cancer cells.
