First Aid 3 Confusions in FA

I have 3 queries which came about while reviewing FA and I need your input to clarify them for me Thanx.

1. It says in CYP 450 Inducers/Induction section that Quinidine is an Inducer but in errata of 2012 FA it is mentioned that Quinidine infact is an Inhibitor So what is the mechanism we have to follow for Exam Induction or Inhibition?

2. It says in 2012 FA that Ciprofloxacin is the DOC for Prophylaxis in meningocci but at other places and in previous editions Rifampin has been mentioned as First line agent.So what is right?

3. This one snit an error or confusion its just the graph on the bottom of pg 53 FA which shows 2 curves overlapping and sensitivity specifity NPV PPV is freaking me out, so please can any one explain it to me in simple words.

Thank you!

Quinidine can induce & inhibit but it went ahead to say its inducing effect is more.

Rifampin is DOC for prophylaxis after exposure to n.meningitis and h.influenza type b.its in uworld too

3.Check the graph in Kaplan video,dr Daugherty did a nice job on it
