Bearing in mind even Neil Armstrong was on record about reserving the right to be "wishy washy about a choice.. " (of the landing area) I'll offer the folowing..:
Q1. Where are we? Where are we going? What's the cost v benefit to the company of further delay vs. picking up a fine at the destination? ( tight connections, curfews etc etc - ? If possible might be worth contacting destination ops for more info before making a decision.
Q2: How critical is the medicine? Do you have similar in the Aircraft first aid kit? ( might mean another call, this time to medical advisors, if available, before making a decision)
Q3: Probably have to have a heart of stone not to turn back for that unless you're trying to escape civil war or tornado...( gretaer risk to the many etc if you go back). Presumably moot since we all know phones are supposed to be off early on in procedings, but in similar context I know of a company flight being delayed because a crew member got v bad news during boarding..
Hope that's vague enough with enough might and perhapses...
