ASQ Certified Medical Device Auditor Examination Practice Test

Medical device auditing examines whether design, production, and quality-system controls generate reliable evidence that devices meet defined requirements. The available practice questions sample design planning and validation, usability considerations, inspection criteria, software-change assessment, labeling review, regulatory records, and management response to quality-system performance.

About the ASQ Certified Medical Device Auditor Examination Exam

Auditors need to trace requirements into controlled procedures and objective records, then determine whether implementation is consistent across the organization. Relevant judgment includes checking how user needs inform design inputs, how validation demonstrates intended use, and how inspection acceptance criteria are established. Scenarios also address assessing the potential safety or performance effects of software changes, reviewing symbols and promotional claims for adequate support, and identifying the extent of a document-control problem when an obsolete instruction is in use. Other tasks involve evaluating timely access to records, interpreting quality metrics during management review, and determining whether processes interact as planned. These examples emphasize evidence-based audit reasoning: distinguish a documented procedure from proof that it is followed, investigate the scope and consequences of gaps, and connect findings to the applicable process controls.

Sample Practice Questions

Review a selection from this exam's published US Practice Tests practice bank.

Question 1

An auditor is reviewing design inputs for a device intended to be operated by users with varying levels of experience. Which evidence best supports that usability-related needs were considered during design planning?

  1. AA documented assessment linking intended users and use environments to relevant design inputs
  2. BA list of suppliers approved for device components
  3. CA production schedule showing planned build quantities
  4. DA record of final product inspection results
Show answerCorrect answer: A

Design inputs should account for intended users, use environments, and relevant user needs. A documented assessment connecting these factors to design inputs provides traceable evidence that they were considered.

Question 2

A manufacturer receives a request to provide device records to an authorized regulator. Which quality-system practice best supports a timely, reliable response?

  1. AMaintaining controlled, retrievable records with clear ownership and retention arrangements
  2. BKeeping records only in the personal folders of the employees who created them
  3. CReconstructing records from memory after receiving the request
  4. DDiscarding older records whenever a newer procedure is issued
Show answerCorrect answer: A

Controlled, retrievable records and defined retention arrangements enable the organization to locate and provide reliable information when needed. Personal storage and reconstruction undermine record integrity and availability.

Question 3

During review of a quality-system metric, management sees a sustained decline in on-time completion of required activities. What is a useful management-review response?

  1. AReview the trend, assess its significance, and determine whether actions or resources are needed
  2. BDelete the metric because it may make performance appear unfavorable
  3. CWait until an external auditor raises the issue before discussing it
  4. DChange the target to match current performance without evaluating the cause
Show answerCorrect answer: A

Management review should use relevant performance information to assess the quality system and determine appropriate decisions, actions, or resource needs. Removing an unfavorable measure or changing a target without evaluation prevents meaningful oversight.

Question 4

A manufacturer is planning inspection activities for a newly introduced device. Which approach best supports defining appropriate acceptance criteria?

  1. ASet criteria after reviewing the first production lot
  2. BUse criteria derived from applicable requirements and documented product specifications
  3. CAccept any result that is within the supplier's usual range
  4. DLet each inspector select criteria based on experience
Show answerCorrect answer: B

Acceptance criteria should be established and documented against applicable requirements and specifications before inspection results are evaluated, so decisions are consistent and justified.

Question 5

A manufacturer is determining whether a proposed software update could affect device safety or performance. Which initial activity is most appropriate?

  1. AAssess the change's potential effects and determine the verification and validation needed before release
  2. BRelease the update first, then collect user feedback to decide whether testing is necessary
  3. CTreat the update as administrative because it does not change the device's physical materials
  4. DUse the same testing as the prior update without considering differences in the current change
Show answerCorrect answer: A

A software change should be evaluated for its potential effect on device function, safety, and performance. The assessment informs suitable verification and validation before release; a change's software-only nature does not make it automatically low risk.

Question 6

A device's packaging artwork includes a symbol whose meaning may not be clear to all intended users. What should the manufacturer do before approving the artwork?

  1. AVerify that the labeling is appropriate for intended users and meets applicable labeling requirements
  2. BApprove it if the symbol is used by a competing manufacturer
  3. CAssume that users will infer the symbol's meaning from the device design
  4. DRemove all symbols and rely only on the package color
Show answerCorrect answer: A

Labeling should be reviewed for suitability to intended users and applicable requirements, including whether symbols are properly selected and understandable or explained where necessary. Competitor practice or assumptions about user interpretation are not adequate evidence of suitability.

Question 7

What is the primary purpose of design validation for a medical device?

  1. ATo confirm that specified design outputs were produced correctly
  2. BTo demonstrate that the device meets user needs and intended uses under defined conditions
  3. CTo prove that every manufacturing batch will be identical
  4. DTo establish that all suppliers have equivalent quality systems
Show answerCorrect answer: B

Design validation provides evidence that the resulting device can meet user needs and intended uses. Design verification, by contrast, checks whether design outputs meet specified design inputs. Validation is planned and performed under defined conditions, often using representative product.

Preparation tips

  • For design-control scenarios, trace user needs through design inputs, outputs, verification, and validation; distinguish evidence of usability consideration from evidence that a device meets intended-use needs.
  • When evaluating software updates or promotional claims, identify the documented basis for assessing effects on device safety or performance and for substantiating statements about clinical benefit.
  • Practice determining the scope of document-control findings by checking affected workstations, records, processes, and product since the superseded instruction was introduced.
  • For inspection-planning questions, relate acceptance criteria to defined requirements and the evidence needed to make a consistent disposition.
  • Interpret declining quality metrics as management-review input: consider trend significance, process causes, assigned actions, and follow-up evidence of effectiveness.
