Fiction. No real student, family or grade appears.

Antibiotic stewardship. The prescription that helps this patient a little is the one that costs the next patient a lot.

Drawing, panel 31: Antibiotic mechanisms.

Cell wall, protein synthesis, DNA replication, membrane. Four things to break, and each class of antibiotic breaks one.

Drawing, panel 32: Disk diffusion and MIC lab.

Disks of antibiotic on a lawn of bacteria, and you measure the clear zone where nothing grew. For any one antibiotic a bigger zone means this organism is more susceptible to it.

We measured the same plate and got different numbers. Agree on a rule, then remeasure everything.

Drawing, panel 33: Resistance and stewardship.

How resistance arises and spreads. It is not that individual bacteria learn, it is that the ones that already survive get to reproduce.

Panel 33Resistance and stewardship
Drawing, panel 34: Antibiotics report submission.

Zone measurements, comparison, a claim about which agent was most effective, and the measurement disagreement written into the limitations.

Drawing, panel 35: HOSA competitive event.

HOSA is choosing competitive events. I am looking at medical terminology because the vocabulary overlaps with what this class already makes me learn, and doing two things with one effort is the only way I get.
