Question 1 of 10Pass mark: 80%

Question 1 of 10 Which inspection finding would most strongly indicate that an organisation has implemented the article's governance expectations?

All mosunetuzumab cases are pooled under a single product code Procedures and database fields distinguish IV and SC products, and route-dose inconsistencies are reviewed Only spontaneous reports of CRS are retained Injection-site reactions are grouped with all systemic hypersensitivity events

Question 2 of 10 A case report states that the patient developed CRS after mosunetuzumab but does not identify the route or step-up dose. What is the main pharmacovigilance limitation?

The case cannot be medically valid without a laboratory-confirmed cytokine result The case cannot be used for any aggregate safety analysis The case has reduced value for route-specific and dose-position-specific evaluation The case must automatically be recoded as an injection-site reaction

Question 3 of 10 A report documents a subcutaneous administration using a strength and step-up position that do not match the expected regimen. What is the most appropriate initial PV action?

Ignore the discrepancy because the active substance is correct Automatically conclude that the patient experienced CRS Flag the case for review and verify product, route, strength and dosing history Delete the administration record and retain only the adverse-event term

Question 4 of 10 Why is cycle/day and prior dosing history important in a subcutaneous mosunetuzumab case?

It establishes the patient's insurance eligibility It helps define the patient's position in the step-up regimen and the relevant CRS susceptibility window It determines whether an injection-site reaction is reportable It replaces the need to document the exact product and route

Question 5 of 10 Which adverse-event group is most appropriately reviewed across the patient's full mosunetuzumab treatment history rather than only by formulation?

Injection-site reactions only Product-selection errors only Infection, hypogammaglobulinaemia and consequences of B-cell depletion Needle-related discomfort only

Question 6 of 10 Which statement best describes why subcutaneous mosunetuzumab requires formulation-specific pharmacovigilance even though it contains the same active antibody as the intravenous product?

The subcutaneous formulation has a different molecular target and therefore a different pharmacology The route changes absorption kinetics, dosing implementation, early cytokine behaviour and product-selection risks The subcutaneous formulation does not cause immune-mediated adverse reactions The intravenous and subcutaneous products are interchangeable if the total dose is equivalent

Question 7 of 10 What is the principal medication-error risk created by treating the subcutaneous product merely as a convenience version of intravenous mosunetuzumab?

The system may fail to distinguish products, routes, strengths and dosing architectures, allowing wrong-product use to go undetected The system will overestimate injection-site reactions in every patient The system will be unable to identify B-cell depletion The system will prevent all aggregate analyses of CRS

Question 8 of 10 Which interpretation of the subcutaneous cytokine profile is most appropriate for pharmacovigilance planning?

CRS surveillance can be discontinued because subcutaneous exposure does not produce cytokine increases CRS should be expected to occur at exactly the same time as after intravenous administration Subcutaneous administration may produce a slower and reduced cytokine-release pattern, but CRS remains clinically relevant Any fever after subcutaneous administration should be classified as CRS

Question 9 of 10 A patient develops confusion and aphasia after subcutaneous mosunetuzumab. Which approach best reflects the article's guidance?

Classify the event immediately as ICANS without further evaluation Assume it is an injection-site reaction because the product was administered subcutaneously Evaluate neurologic toxicity while considering infection, metabolic disturbance, CNS lymphoma and concomitant treatment effects Exclude the event from PV because neurologic effects are unrelated to the route

Question 10 of 10 What is the primary biological rationale for retaining step-up dosing with subcutaneous mosunetuzumab?

To prevent injection-site reactions caused by the needle To gradually suppress B-cell depletion before full treatment begins To reduce the risk associated with rapid T-cell activation in the presence of CD20-positive cells To ensure that subcutaneous absorption is complete before the next cycle
