McPake is taking nothing for granted in the relegation battle but he is aiming higher with Inverness five points ahead.
"You can blow it if you're complacent and you think it's done," the on-loan Coventry player said.
"I'm sure there have been bigger gaps blown. We have to make sure we are professional and pick up as many points as we can.
"We're still looking to catch Inverness. There is no way a club this size should be second bottom of the league.
"We have no divine right, you have to earn the points. Obviously the first aim is to avoid relegation but we want to catch them as well."
Hibs now take a break from their survival fight with a Hampden clash against Aberdeen in the William Hill Scottish Cup semi-finals on Saturday.
"It was a big game on two fronts, we had to gain confidence going into a massive game for this club," the former Livingston player said.
"It's been 110 years since we have won this cup. I didn't realise what it meant to the fans when I came up here but it's the holy grail to the Hibernian fans."
