Before you ask the officiant to declare, “You may give mouth to mouth to the groom,” or use bedpans to hold the flowers in your table decorations, consider the tone you want for the wedding. Having a white cake with a red cross and cake topper of a nurse bride may be as overtly nurse-themed as you want your wedding to be. However, if the bride and groom are gung ho about their medical professions, make it as over the top as possible.
Red and White
Use red and white, the traditional nursing colors, with old-fashioned white nurses’ hats with red crosses as the theme in your invitations and reception. Real nurses’ hats and toy ambulances can be part of the table decorations, along with red "syringes" that are actually pens. Use actual hospital gurneys for the cake and gift tables. The medical symbol, with snakes on the staff, or stethoscopes can be used on the invitations, cake and table decorations.
Red Drinks and Food
Much of the medical profession is not very appetizing; you probably don't want to make your guests nauseous with food in the shape of a pancreas, but you can use red gelatin in the shape of a cross. Blood-red martinis or Bloody Marys work with the nursing theme, as do strawberry daiquiris or margaritas. An IV bag set up to dispense alcohol is crazy but fun.
Have your wedding in the hospital chapel. As decoration, install an ice sculpture in the shape of a red cross, a stethoscope or anything nurse-related. The groomsmen can wear black scrubs, while the bridesmaids dress in old-fashioned white nurses’ uniforms. Use an ambulance for your getaway car. Save the drinks served in specimen cups for your shower or bachelor party.
