Hemolysis, nothing, the first time antibodies are produced, antbodies
against ABO blood types are already present, anti Rh antibodies
develop after exposure

2.02 Prototype Assessment Items
Note: These items illustrate the types of items used in the item bank for this
objective. All items have been written to match the cognitive process of the
understand verb in the objective. Questions require students to interpret,
summarize or explain safety procedures. These exact questions will not be used
on the secured test, but questions in similar formats will be used.
These assessment items may be used as prototypes by teachers and students to
generate similar items to comprise formative assessments for you classroom.
This strategy is especially helpful during the field test year when classroom item
banks are not available. Results of formative assessment should be used to
diagnose levels of mastery, determine if re-teaching is needed, and guide further
instruction.
