What is used to estimate the size and depth of burns? - ANSWER-Rule of 9's
Head= 9%
Each arm=9%
Front Trunk= 18%
Back Trunk= 18%
Upper leg= 9%

Hospital admission criteria for burn pt
(8) - ANSWER-1) Partial-thickness burns greater than 10% total BSA (TBSA)
2) Full-thickness burns greater than 2% TBSA
3) Burns involving the face, hands, genitalia, perineum, or major joints
4) Circumferential extremity burns
5) All high-voltage electrical burns, including lightning injury--Admission of low-voltage electrical burns is
selective
6) Chemical burns
7) Inhalation injury
8) Burn injuries in patients with preexisting medical disorders that could complicate management,
prolong recovery, or affect mortality (eg, diabetes, immunosuppression)
Parkland Formula for Fluid Resuscitation in Burn pt - ANSWER-3-4 mL Ringer lactate X weight (kg) X
%TBSA burned (second-degree and third degree);

next 16 hours*
What injuries may necessitate inter-hospital transfer?
(3) - ANSWER-1) Head or spinal cord trauma
2) Pulmonary contusions
3) Severe burns
*consider time between injury and definitive care as well as resources available at local facilities*

C. Apply iced water to burned areas until cool to touch
D. Do not apply anything to burned areas other than clean sheets - ANSWER-B. Apply clean water to
burned areas for up to 1-2 minutes
What treatment is NOT indicated in the routine management of the patient with a head injury?
A. Administration of 100% oxygen
