Gary Cahill curled in a fine 20-yard effort on the stroke of half-time, and once defender Danny Gabbidon had put through his own net, there was no way back for Rangers. QPR lost summer signing Kieron Dyer to a metatarsal injury after just five minutes and finished the afternoon with 10 men after defender Clint Hill was shown a red card for putting his head into the chest of Martin Petrov.
Warnock, however, insists all is not lost for his side and he said: "It was disappointing how we capitulated at 2-0 and we are going to have to learn lessons quickly. You have to look at all that really and rather than commit suicide, you have to say 'how can I eliminate the errors?' and that is what I am going to try to do."
He added: "We defended poorly and got punished, which is what happens in the Premier League.
"Up until the second goal, we created some chances and could have scored, the crowd got behind us.
"I am not happy we lost 4-0, but sometimes you have to smile through adversity. We do need one or two players, and I am confident we can get them in the next fortnight before the end of the window.
"There is something to work on and with the players I want, I still think we have an outside chance (of staying up)."
Warnock revealed there was positive news on Dyer.
"The good news is there is no break on the bones and might just be a soft tissue injury, which is not a long-term thing," said Warnock, who intends to appeal Hill's dismissal. "We just have to cross our fingers that he has a bit of luck for a change."
Bolton went on to secure a comfortable victory through Ivan Klasnic's deflected strike ahead of a fourth for Fabrice Muamba following a swift counter-attack with 11 minutes left.
