It's a fantasy role-playing game.

DM: You are Vax Vax'ildan, a half-elf rogue . You are the member of the famous group of adventurers. Previously, Grog sprints directly into the mansion with Pike in his arms. you'ildan rockets towards the mansion door, stabbing Ghurrix in the face as he passes.
DM: You could use your haste attack to hit him on the way through, and that can only be used as an attack anyway, because that's the nature of the haste bonus. You can use your action to neutralize the poison.
Player: All right, question for Matt, and I'm Liam right now. If I bring her up ten hit points, right, poison doesn't bring her down anymore in 5e, it just puts her to disadvantage, correct?
DM: This poison, you're not quite sure. You don't know the circumstance.
Player: I'm going to use five points of Lay on Hands to cure the poison.
DM: Okay, so the poison is removed from her. That is as much as you can do.
Player: Well, if I can only use Lay on Hands once, I'm going to throw another dagger out the door into the pit fiend--
DM: You cannot see him from that side of the door. The doorway is facing outward. He's on the other side of the doorway. That is the end of your turn. Pike is no longer poisoned. The bulging black veins retract from her throat. The shallow breath is still there, though fading. Percy.
