Medical and Biomedical Technology Questions

Multiple choice

Consider the following statements:

  1. Nanotechnology is also called atomic engineering.
  2. Nanotechnology is useful in destroying tumors of cancer.

Which of the given statements is/are correct?

  1. Only (1)

  2. Only (2)

  3. Both (1) and (2)

  4. Neither (1) nor (2)
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

(1) Nanotechnology is also called carbon engineering. (2) Yes, nanotechnology is useful in destroying tumors of cancer. A nanoshell of 100 nm diameter floating through the body will be able to get attached only to cancerous cells, which, upon excitation by a laser beam, will dissipate heat and destroy the tumor.

Multiple choice

Which of the following is a method of gene delivery using nanomaterials?

  1. Electroporation

  2. Impalefection

  3. Microinjection

  4. Biolistics

  5. Liposome mediated transfer
Reveal answer Fill a bubble to check yourself
E Correct answer
Explanation

Liposomes are able to interact with the negatively charged cell membrane more readily than uncharged liposomes, with the fusion between cationic liposome and the cell surface resulting in the delivery of the DNA directly across the plasma membrane.

Multiple choice

What is/are the advantage(s) of using nanotechnology for medical applications?

  1. Nanodevices are less invasive and can be implanted inside the body.
  2. Biochemical reaction takes longer time at nanoscale, hence healing is complete.

  1. Only 1

  2. Only 2

  3. Both 1 and 2

  4. Neither 1 nor 2
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Nanomedicine ranges from medical applications of nanomaterials to nanoelectronic biosensors and even possible future applications of molecular nanotechnology. A benefit of using nanoscale for medical technologies is that smaller devices are less invasive and can possibly be implanted inside the body.

Multiple choice

Which of the following is not the indication of catheterization?

  1. Retention of Urine

  2. Acute BPH

  3. Paraplegia

  4. Lumber Puncture

  5. Major abdominal and pelvic organ surgery
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

It is a simple procedure in which sample of spinal fluid is taken for diagnostic purpose. No catheterzation is required for a general patient.

Multiple choice

Which one of the following antibiotic is used?

In hybridoma technology for monoclonal Ab production antibiotic is used to select hybridoma cell over myeloma cells.

  1. Gentamycin

  2. Aminopterin

  3. Novobiocin

  4. Penicillin

  5. Rifampicin
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Aminopterin is used to select hybridoma over myeloma . Aminoptorine inhibits the denovo nucleotide synthesis pathway . However normal cells survive in a medium as they are able to use salvage pathway for nucleic acid biosynthesis. But if the cell unable to produce the enzyme Hypoxanthine Guanine Phospho Ribosyl –Transferase ( HGPRT ) utilized in salvage pathway, they die. Here in this method, myeoloma cell lack that particular enzyme thus, they die in Aminopterin containing medium.

Multiple choice

Which of the following statements is/are correct about micro biosensors?

  1. Microbiosensors are based on piezoelectric effect.
  2. They can be integrated on one chip and are useful for measuring various substrates in a small amount of sample solution simultaneously.
  3. It is possible to develop disposable transducers for biosensors through mass production.

  1. Only 1

  2. Only 2

  3. Only 3

  4. 1 and 2

  5. 2 and 3
Reveal answer Fill a bubble to check yourself
E Correct answer
Explanation

Micro biosensors can be integrated on one chip and are useful for measuring various substrates in a small amount of sample solution simultaneously. It is possible to develop disposable transducers for biosensors through mass production.

Multiple choice

Match the entries in group I with that in group II and select the correct answer.

 
Group I
Group II
P. Overlap-extension PCR 1. Splices together two or more DNA fragments that contain complementary sequences
Q. Hot start PCR 2. Reduces non-specific amplification during the initial set up stages of the PCR
R. Asymmetric PCR 3. Preferentially amplifies one DNA strand in a double-stranded DNA template
S. Digital PCR 4. Measures the quantity of a target DNA sequence in a DNA sample

  1. P - 1, Q - 2, R - 3, S - 4

  2. P - 1, Q - 3, R - 2, S - 4

  3. P - 2, Q - 1, R - 4, S - 3

  4. P - 2, Q - 3, R - 4, S - 1

  5. P - 4, Q - 3, R - 2, S - 1
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Overlap-extension PCR is a genetic engineering technique that is used to splice together two or more DNA fragments that contain complementary sequences. Hot start PCR is a technique that reduces non-specific amplification during the initial set up stages of the PCR. Asymmetric PCR preferentially amplifies one DNA strand in a double-stranded DNA template. Digital PCR is used to measure the quantity of a target DNA sequence in a DNA sample.

Multiple choice

Directions: For this question, select the best of the answer choices given.

Although the new cochleae manufactured by Medotech will cost more than twice as much as the cochlear implants now in use, Medotech implants should still be cost-effective. Not only will surgery and recovery time be reduced, but Medotech cochlear replacements should last longer, thereby reducing the need for further hospital stays. Which of the following must be studied in order to evaluate the argument presented above?

  1. The amount of time a patient spends in surgery versus the amount of time spent recovering from surgery.

  2. The amount by which the cost of producing Medotech cochlear replacements has declined with the introduction of the new technique for producing them.

  3. The degree to which the use of Medotech cochlear replacements is likely to reduce the need for repeat surgery when compared with the use of the replacements now in use.

  4. The degree to which the use of Medotech replacements are more carefully manufactured than are the replacements now in use.

  5. The amount by which Medotech will drop in cost as the production procedures become standardized and applicable on a larger scale.

C Correct answer
Explanation

The best answer is (3). To evaluate the argument it must be determined whether these savings will compensate for the increased cost. Therefore, study of the expected reduction in the need for further hospital stays is needed.
