The Welsh club missed a great opportunity to push further clear of the relegation zone when the Baggies got the better of them at the Liberty Stadium but they get the chance to atone at Everton this Saturday.
A win could see Swansea move seven points clear of the bottom three and Monk is expecting a much-improved showing at Goodison Park against the sixth-placed Toffees.
"It wasn't rocket science what I had to tell them," Monk said in regards to the defeat. "It was the truth, and they have taken it on board.
"If you have a group who doesn't want to improve and put the work in then you have a problem. But this group is not like that.
"It was important to look back at what we've not done so well in recent games, and that's what we've shown the players.
"When you get questioned there's usually a reaction, and I hope that's the case this weekend. For me, the good thing is that it's in our own hands."
Swansea currently sit 14th on the table on 29 points and will be looking for a win on Merseyside after failing to record three points in their past four outings.
