if and only if
If (and only if) the victim is more than an hour away from a medical facility, place a lightly constricting band (that admits one finger beneath it) above the bitten area to prevent the systemic spread of the venom.
This line needs to be changed to reflect the intended meaning of "If (and only if)". As it is now it means that if you have placed a lightly constricting band around the wound, the victim is more than an hour away from a medical facility. But I'm sure it's meant to mean that you should not use a band if you are an hour or less away from a medical facility.
It would also be nice to know why you shouldn't if you're nearby to a medical facility, I assume it's because it wouldn't be worth the time spent, but I can't read the citation so I don't know the reason. — Preceding unsigned comment added by 188.8.131.52 (talk) 09:33, 26 April 2015 (UTC)
- It's correct as written. You're parsing it as the formal logic operator iff, which is not applicable in the context of this article, and in any event is not applicable when the subject clause of the condition ("place a lightly constricting band...") is an imperative clause rather than a declaratory clause.
