Nurse

The Nurse is an NPC that will spawn once the following criteria have been met:
 * There is an empty house.
 * You have more than 100 maximum health (you have used at least one Life Crystal to increase your maximum health).
 * Merchant is alive.

The Nurse will heal your wounds and cure you of any active debuffs, for a small price. Healing costs can range from a few copper to a few silver, depending on how much damage you've taken. She charges Copper equal to 75% of the health restored (e.g. 75 copper for 100 health), plus an additional 7 silver coins and 50 copper coins for every active debuff on your character.

Names
The nurse may have any of the following names: Molly, Amy, Claire, Emily, Katie, Madeline, Katelyn, Emma, Abigail, Carly, Jenna, Heather, Katherine, Caitlin, Kaitlin, Holly, Kaitlyn, Hannah, Kathryn, Lorraine, Helen, Kayla, and Allison.

Seven of the nurse's possible names are variations on "Catherine".

Trivia

 * There appears to be conflict between the Nurse and the Mechanic during a Blood Moon. When both are present, they have various hostile sayings that replace their standard quotes (see Quotes). During this time, the Merchant has a chance of saying, "Oh, great. I can hear [name of Mechanic] and [name of Nurse] arguing from here."
 * The Arms Dealer has a crush on her according to one of his quotes.

Quotes
Note: The Nurse has many quotes that vary with the amount of damage you've taken, whether or not you have enough coins to pay, and whether it is a Blood moon.

Anytime other than during a Blood Moon:
 * "Show me where it hurts."
 * "That's not the biggest I've ever seen... Yes, I've seen bigger wounds for sure."
 * "Turn your head and cough."
 * "I wish [Name of Demolitionist] would be more careful. I'm getting tired of having to sew his limbs back on every day." (Only if Demolitionist is present.)
 * "Would you like a lollipop?"
 * "I need to have a serious talk with [Name of Guide]. How many times a week can you come in with severe lava burns?" (reference to the effects of the Guide Voodoo Doll when it is thrown into lava.)
 * "Hey, has [Name of Arms Dealer] mentioned needing to go to the doctor for any reason? Just wondering." (Only if Arms Dealer is present.)
 * "Have you seen that Old Man pacing around the dungeon? He looks troubled." (Only if Skeletron is not defeated.)

When player is moderately injured:
 * "Quit being such a baby! I've seen worse."
 * "Trouble with those bullies again?"
 * "That's gonna need stitches!"
 * "You look half digested. Have you been chasing slimes again?"
 * "Hold on, I've got some cartoon bandages around here somewhere."
 * "Walk it off, (Name of Player), you'll be fine. Sheesh."
 * "Does it hurt when you do that? Don't do that."

When player is badly injured:
 * "Dear friends we are gathered here today to bid farewell... oh, you'll be fine."
 * "I think you look better this way."
 * "Eww.. what happened to your face?"
 * "You left your arm over there. Let me get that for you."
 * "MY GOODNESS. I'm good but I'm not THAT good."

During a Blood Moon:
 * When player is at full health to moderately injured:
 * "What is that supposed to mean!?"
 * "I don't think I like your tone."
 * "Why are you even here? If you aren't bleeding, you don't need to be here. Get out."
 * "WHAT?!"


 * When player is badly injured:
 * "If you're going to die, do it outside."
 * "Hurry up and stop bleeding."
 * "You better not get blood on me."

When player clicks Heal:
 * When player clicks Heal if slightly injured:
 * "That didn't hurt too bad, now did it?"
 * When player clicks Heal if moderately injured:
 * "All better. I don't want to see you jumping off any more cliffs."
 * When player is badly injured:
 * "That's probably going to leave a scar."
 * When player clicks Heal if very badly injured:

 * When player clicks Heal at full health:
 * "Quit wasting my time."
 * "I don't give happy endings."
