Introduction

ISBT and International Haemovigilance Network (IHN) standards MCQs With Answer offers M.Pharm students a focused review of international standards that govern blood product identification, labeling, traceability and haemovigilance reporting. This quiz collection emphasizes ISBT 128 coding, donation identification, product description codes, barcoding symbologies, and practical haemovigilance concepts such as adverse reaction classification, lookback procedures, confidentiality and timelines for reporting. Questions are designed to deepen understanding of regulatory expectations, system components and global coordination mechanisms (ICCBBA and IHN). Use these MCQs to test, reinforce and prepare for regulatory discussions, audits and clinical safety responsibilities in transfusion and blood‑related product management.

Correct Answer: Code 128

Q6. One of IHN’s operational expectations for national haemovigilance systems is initial reporting of serious transfusion reactions within what timeframe?

• Within 24 hours of recognition
• Within 7 days of recognition
• Within 30 days of recognition
• Only at annual summary submission

Correct Answer: Within 24 hours of recognition

Q7. Which of the following best describes a key objective of the International Haemovigilance Network (IHN)?

• To improve transfusion safety by harmonizing definitions and facilitating information exchange between countries
• To license blood establishments worldwide
• To set mandatory legal penalties for transfusion incidents
• To manufacture blood test reagents for global distribution

Correct Answer: To improve transfusion safety by harmonizing definitions and facilitating information exchange between countries

Q8. Which of the following is included under haemovigilance activities?

• Surveillance and investigation of both adverse reactions and adverse events related to transfusion and donation
• Only monitoring donor eligibility criteria
• Only pharmaceutical adverse event reporting unrelated to blood products
• Quality control of reagent production unrelated to transfusion safety

Correct Answer: Surveillance and investigation of both adverse reactions and adverse events related to transfusion and donation

Q9. The ISBT 128 Donation Identification Number (DIN) incorporates which essential component to identify the issuing facility?

• Facility Identification Number (FIN)
• Manufacturer Lot Number
• Patient Hospital ID
• Temperature Indicator Code

Correct Answer: Facility Identification Number (FIN)

Q10. Which standardized transfusion reaction term refers to acute pulmonary edema due to cardiac fluid overload following transfusion?

• Transfusion-associated circulatory overload (TACO)
• Transfusion-related acute lung injury (TRALI)
• Acute hemolytic transfusion reaction (AHTR)
• Febrile non-hemolytic transfusion reaction (FNHTR)

Correct Answer: Transfusion-associated circulatory overload (TACO)

Q11. Which of the following is an example of a lookback investigation in haemovigilance?

• Tracing and notifying recipients of past donations from a donor who later tests positive for an infectious marker
• Conducting a clinical trial on a new blood storage solution
• Performing routine blood counts on all donors
• Issuing press releases about blood shortages

Correct Answer: Tracing and notifying recipients of past donations from a donor who later tests positive for an infectious marker

Q12. Which of the following data elements is NOT typically encoded in an ISBT 128 label?

• Donor blood pressure at donation
• Donation Identification Number
• Product Description Code
• Expiry date of the component

Correct Answer: Donor blood pressure at donation

Q13. The ISBT Product Description Code (PDC) is typically how many characters in length?

• Five characters
• Three characters
• Eight characters
• Twelve characters

Correct Answer: Five characters

Q14. Which of the following is considered an essential component of an effective haemovigilance system?

• Structured reporting, investigation, analysis and feedback mechanisms
• Exclusive focus on marketing blood services
• Storing blood products without records
• Elimination of donor confidentiality to increase data access

Correct Answer: Structured reporting, investigation, analysis and feedback mechanisms

Q15. Why is the use of standardized case definitions by IHN important for international haemovigilance?

• It enables comparability, pooling and meaningful analysis of data across centres and countries
• It allows each centre to invent unique event labels for internal use
• It replaces the need for local clinical investigation
• It mandates a single global regulatory authority

Correct Answer: It enables comparability, pooling and meaningful analysis of data across centres and countries

Q16. Which principle is central to maintaining confidentiality in haemovigilance reporting?

• Protecting donor and recipient identity while allowing de-identified data sharing for safety analysis
• Publicly releasing donor names to improve transparency
• Storing all haemovigilance files without access controls
• Publishing full medical records in annual reports

Correct Answer: Protecting donor and recipient identity while allowing de-identified data sharing for safety analysis

Q17. Which storage temperature range is commonly required for packed red blood cells?

• 1–6 °C
• 15–25 °C
• -80 °C
• 10–15 °C

Correct Answer: 1–6 °C

Q18. Which transfusion reaction is defined by acute hypoxemia and bilateral pulmonary infiltrates not explained by circulatory overload, usually occurring within 6 hours of transfusion?

• Transfusion-related acute lung injury (TRALI)
• Febrile non-hemolytic transfusion reaction (FNHTR)
• Acute hemolytic transfusion reaction (AHTR)
• Allergic urticarial transfusion reaction

Correct Answer: Transfusion-related acute lung injury (TRALI)

Q19. One of the primary aims of implementing ISBT 128 labeling is to reduce which type of error?

• Performing root-cause analysis followed by system changes and feedback to stakeholders
• Ignoring near‑miss events because no harm occurred
• Only recording events without investigation
• Replacing haemovigilance staff frequently to avoid responsibility

Correct Answer: Performing root-cause analysis followed by system changes and feedback to stakeholders
