AMR MCQs

Of course! Here are multiple-choice questions based on the provided text, organized by topic.

### Section 1: Fundamentals of Antimicrobials and AMR

1. What is the broad definition of antimicrobials?

b) Substances used to prevent and treat infections in humans, animals, and plants.

c) Chemicals that kill all microbes, including beneficial ones.

d) A specific class of drugs derived from fungi.

2. Which of the following is NOT a category of antimicrobials?

a) Antivirals

b) Antibiotics

c) Antipyretics

d) Antifungals

3. Antimicrobial Resistance (AMR) occurs when:

a) The human immune system becomes stronger.

b) Medicines become more potent and effective over time.

c) Microbes change and no longer respond to medicines, making infections harder to treat.

d) Patients take their medication exactly as prescribed.

4. The term "microbes" in the context of AMR includes:

b) Only multi-cellular parasites.

c) Bacteria, viruses, fungi, and parasites.

d) Only single-celled organisms.

### Section 2: The Scope and Impact of AMR

5. Using Tuberculosis (TB) as an example, what is a major cause of multidrug-resistant strains?

a) The development of a universal vaccine for TB.

b) The overuse and misuse of antibiotics.

c) The bacteria Mycobacterium tuberculosis is naturally resistant to all drugs.

d) Improved global sanitation standards.

6. The "ESCAPE" pathogens refer to:

a) A list of the most common viral infections.

b) A group of pathogens of high concern due to their increasing antibiotic resistance.

c) Beneficial bacteria that are endangered by antimicrobial overuse.

d) The first microbes to be eradicated by modern medicine.

7. Why is AMR considered a global threat?

a) It only affects healthcare in developing countries.

b) It threatens progress in healthcare, food production, and life expectancy.

c) It makes vaccines completely ineffective.

d) It causes an immediate and dramatic increase in all food prices.

8. In 2019, the estimated number of deaths directly caused by bacterial AMR was approximately:

a) 4.9 million

b) 1.3 million

c) 10 million

d) 500,000

9. The significant cost of AMR to national economies and healthcare systems is primarily due to:

a) The decreased cost of newer, simpler drugs.

b) Increased productivity of patients and caretakers.

c) Prolonged hospital stays and the need for more expensive care.

d) A reduction in the number of people seeking medical help.

### Section 3: How AMR Develops and Spreads

10. What is the correct sequence for the development of AMR?

a) Antibiotic kills all bacteria -> Resistant bacteria multiply -> Resistance genes are transferred -> Some bacteria are naturally resistant.

b) High number of bacteria, some resistant -> Antibiotic kills susceptible bacteria -> Resistant bacteria multiply without competition -> Resistance is transferred.

c) Resistance is transferred -> All bacteria are killed -> Resistant bacteria appear -> Bacteria multiply.

d) Bacteria multiply -> Antibiotic has no effect -> All bacteria become resistant -> Resistance is transferred.

11. The difference between innate and acquired resistance is that:

a) Innate resistance is developed through mutation, while acquired is present from birth.

b) Innate resistance is a microbe's natural ability to resist a drug, while acquired is when a susceptible microbe gains resistance.

c) Acquired resistance only occurs in viruses, while innate resistance occurs in bacteria.

d) Innate resistance can be transferred between bacteria, while acquired resistance cannot.

12. Which of the following is a method of HORIZONTAL gene transfer for antibiotic resistance?

a) Bacterial replication (Vertical Gene Transfer)

b) Conjugation

c) Cell division

d) Binary fission

13. In which genetic transfer method does a virus carry bacterial DNA from one cell to another?

a) Conjugation

b) Transformation

c) Transduction

d) Replication

14. A bacterium develops resistance by pumping an antibiotic out of its cell as soon as it enters. This is an example of which mechanism of resistance?

a) Limiting uptake of a drug

b) Modification of a drug target

c) Inactivation of a drug

d) Active efflux of a drug

a) Waste, Air, Safety, and Health

b) Water, Antibiotics, Sanitation, and Hygiene

c) Water, Sanitation, and Hygiene

17. A patient contributing to AMR by not completing their full course of antibiotics is an example of a:

a) Drug-related factor

b) Physician-related factor

c) Environmental factor

d) Patient-related factor

18. A physician contributing to AMR by prescribing broad-spectrum antibiotics before receiving test results is an example of:

a) Inadequate dosing

b) Increase in empiric poly-antimicrobial use

c) Lack of current knowledge

d) Substandard drug quality
