I've always found that straightforward courtesy goes a long way with nurses. In other words, just say "Thank you." Beyond that, a card, flowers, maybe a Starbucks gift certificate? (I suspect there are times when nurses must rely heavily on caffeine.) Also, ask to speak with the Charge Nurse in Merrie's department, and tell *her* (or him) how wonderful and competent Merrie is. That's the kind of thing that goes into an employee file, and could mean more $ for Merrie down the road. The Patient Representative is also a good person to speak to.
Writing a letter or sending card is an amazing idea!
