What is the primary function of a biomaterial?

  1. To replace or repair damaged tissue

  2. To deliver drugs or other therapeutic agents

  3. To monitor physiological parameters

  4. To provide structural support


Correct Option: A
Explanation:

Biomaterials are used to replace or repair damaged tissue, restore function, and improve the quality of life for patients.

Which type of biomaterial is commonly used in orthopedic implants?

  1. Metals

  2. Polymers

  3. Ceramics

  4. Composites


Correct Option: A
Explanation:

Metals, such as titanium and stainless steel, are commonly used in orthopedic implants due to their strength, durability, and biocompatibility.

What is the main advantage of using bioresorbable polymers in medical devices?

  1. They can be broken down by the body over time

  2. They are more flexible than traditional polymers

  3. They have better biocompatibility

  4. They are more resistant to wear and tear


Correct Option: A
Explanation:

Bioresorbable polymers are designed to be broken down and absorbed by the body over time, eliminating the need for a second surgery to remove the device.

Which type of medical device is used to monitor heart rate and rhythm?

  1. Pacemaker

  2. Implantable cardioverter-defibrillator (ICD)

  3. Electrocardiogram (ECG)

  4. Holter monitor


Correct Option: C
Explanation:

An electrocardiogram (ECG) is a medical device used to monitor heart rate and rhythm by recording the electrical activity of the heart.

What is the purpose of a stent in a medical device?

  1. To open up a blocked artery

  2. To support a weakened heart valve

  3. To deliver medication to a specific area of the body

  4. To monitor blood pressure


Correct Option: A
Explanation:

Stents are small, expandable devices used to open up blocked arteries and restore blood flow.

Which type of biomaterial is commonly used in dental implants?

  1. Titanium

  2. Zirconia

  3. Polyetheretherketone (PEEK)

  4. Hydroxyapatite


Correct Option: A
Explanation:

Titanium is commonly used in dental implants due to its strength, durability, and biocompatibility.

What is the main advantage of using nanotechnology in medical devices?

Which type of medical device is used to treat sleep apnea?

  1. Continuous positive airway pressure (CPAP) machine

  2. Bi-level positive airway pressure (BiPAP) machine

  3. Adaptive servo-ventilation (ASV) machine

  4. All of the above


Correct Option: D
Explanation:

All of the mentioned devices are used to treat sleep apnea by providing positive airway pressure to keep the airway open during sleep.

What is the primary function of a biosensor in a medical device?

  1. To detect and measure biological substances

  2. To deliver drugs or other therapeutic agents

  3. To monitor physiological parameters

  4. To provide structural support


Correct Option: A
Explanation:

Biosensors are used to detect and measure biological substances, such as glucose, oxygen, or hormones, in the body.

Which type of biomaterial is commonly used in artificial joints?

  1. Metals

  2. Polymers

  3. Ceramics

  4. Composites


Correct Option: A
Explanation:

Metals, such as titanium and cobalt-chromium alloys, are commonly used in artificial joints due to their strength, durability, and biocompatibility.

What is the main advantage of using 3D printing in the manufacturing of medical devices?

Which type of medical device is used to treat Parkinson's disease?

  1. Deep brain stimulator (DBS)

  2. Vagus nerve stimulator (VNS)

  3. Spinal cord stimulator (SCS)

  4. All of the above


Correct Option: A
Explanation:

Deep brain stimulation (DBS) is a surgical procedure that involves implanting electrodes into specific areas of the brain to alleviate symptoms of Parkinson's disease.

What is the main advantage of using biodegradable materials in medical devices?

  1. They can be broken down by the body over time

  2. They are more flexible than traditional materials

  3. They have better biocompatibility

  4. They are more resistant to wear and tear


Correct Option: A
Explanation:

Biodegradable materials are designed to be broken down and absorbed by the body over time, eliminating the need for a second surgery to remove the device.
