Introduction to medical devices and IVDs: definitions and scope MCQs With Answer

Introduction: This quiz set focuses on foundational concepts in medical devices and in vitro diagnostics (IVDs) tailored for M.Pharm students studying Regulatory Aspects of Medical Devices (MRA203T). It covers definitions, scope, classification principles, regulatory frameworks, quality systems, and practical examples that highlight regulatory requirements and real‑world applications. The questions are crafted to deepen understanding of intended use, risk‑based classification, IVD analytical and clinical performance, post‑market surveillance, and key standards such as ISO 13485 and ISO 10993. Use these MCQs to prepare for exams and to strengthen your regulatory reasoning when assessing device/IVD documentation and compliance strategies.

• Market demand and sales volume

Correct Answer: Intended use and associated risk to patient and user

Q5. Which regulation specifically governs in vitro diagnostic devices in the European Union?

• EU Medical Device Regulation (MDR) 2017/745
• EU In Vitro Diagnostic Regulation (IVDR) 2017/746
• CE Marking Directive 93/42/EEC
• EU Pharmaceutical Directive 2001/83/EC

Correct Answer: EU In Vitro Diagnostic Regulation (IVDR) 2017/746

Q6. Which ISO standard is the recognized Quality Management System requirement for medical device manufacturers?

• ISO 9001
• ISO 14971
• ISO 13485
• ISO 10993

Correct Answer: ISO 13485

Q7. What is a companion diagnostic?

• A type of sterilization indicator for surgical kits
• An IVD that identifies patients most likely to benefit from a specific therapeutic product or at increased risk of adverse reactions
• A device used to monitor manufacturing environmental conditions
• A diagnostic imaging device used alongside MRI

Correct Answer: An IVD that identifies patients most likely to benefit from a specific therapeutic product or at increased risk of adverse reactions

Q8. Which statement best differentiates analytical performance from clinical performance of an IVD?

• Analytical performance describes regulatory approval timeline; clinical performance describes manufacturing location
• Analytical performance relates to reproducibility, sensitivity and specificity at the laboratory level; clinical performance relates to the test’s ability to provide clinically relevant information about patient health outcomes
• Analytical performance concerns user instructions; clinical performance concerns packaging integrity
• Analytical performance is evaluated post-market only; clinical performance is pre-market only

Correct Answer: Analytical performance relates to reproducibility, sensitivity and specificity at the laboratory level; clinical performance relates to the test’s ability to provide clinically relevant information about patient health outcomes

Q9. Which of the following is an example of a medical device rather than a pharmaceutical?

• Insulin injectable solution
• Oral antibiotic tablet
• Infusion pump for delivering fluids
• Vaccines

Correct Answer: Infusion pump for delivering fluids

Q10. Which process is intended to render a medical device free of all viable microorganisms?

• Disinfection
• Cleaning
• Sterilization
• Pasteurization

Correct Answer: Sterilization

Q11. In regulatory documentation, which term refers to the specific diseases, conditions or patient populations for which a device is indicated?

• Label
• Intended use
• Indications for use
• Contraindications

Correct Answer: Indications for use

Q12. How is an accessory to a medical device defined?

• A separate medical product that competes with the primary device
• A product intended to be used together with a medical device to enable its intended purpose or to augment its functionality
• A consumable material used during sterilization only
• A device component that is permanently integrated into the main device during manufacturing

Correct Answer: A product intended to be used together with a medical device to enable its intended purpose or to augment its functionality

Q13. The FDA 510(k) pathway requires demonstrating which of the following for market clearance?

• Full clinical trial evidence proving superiority over existing devices
• Substantial equivalence to a legally marketed predicate device
• Approval from a Notified Body in the EU
• No evidence if the device is low risk

Correct Answer: Substantial equivalence to a legally marketed predicate device

Q14. Under the EU regulatory framework, which entity performs conformity assessment and issues certificates for medical devices?

• European Commission directly
• Notified Body designated by an EU Member State
• Manufacturer self-declaration only for all devices
• World Health Organization (WHO)

Correct Answer: Notified Body designated by an EU Member State

Q15. According to the EU IVDR risk classification, which class indicates the highest risk for in vitro diagnostics?

• Class A
• Class B
• Class C
• Class D

Correct Answer: Class D

Q16. What is the primary purpose of post‑market surveillance (PMS) for medical devices?

• To design initial marketing materials
• To collect and analyze real‑world data on device safety and performance after launch
• To establish manufacturing quotas
• To replace pre‑market clinical evaluation entirely

Correct Answer: To collect and analyze real‑world data on device safety and performance after launch

Q17. Which element is intended to provide traceability of a medical device through distribution and use and is increasingly required by regulators?
