Question 5 - Parkland’s Formula is:

0.5 cc Albumin/ lb/ %BSA
4 cc DsW/ kg/ %BSA
4cc Ringers Lactate/ kg/ %BSA
0.5 cc paked RBC/ kg/ %BSA

5.4 L of normal saline
5.4 L of Ringer’s lactate
11 L of Ringer’s lactate
22 L of Ringer’s lactate

Question 7 - A 50 kg female arrives in the ED with 3rd degree burns extending from the soles of the feet to the knees on both legs. The burns were sustained in a house fire 2 hours prior to arrival. You begin fluid resuscitation using the Parkland formula. What total volume of Ringer’s lactate is required over the next 6 hrs?

1800 cc
3600 cc
1350 cc
450 cc

Question 8 - A 58-year-old man sustains 2nd and 3rd degree burns to the anterior chest and both arms. He has not suffered an inhalation injury. Does the patient get admitted to the burn unit?

Yes, because the 2nd and 3rd degree burns cover more than 20% of his body
No, because he has not suffered an inhalation injury
Yes, because the patient has 2nd and 3rd degree burns over more than 10% of his body
No, because the 2nd and 3rd degree burns cover less than 40% of his body

Question 9 - In the management of a burn patient, it is important to know that:

Burn wound infection can cause progression of a 2nd degree burn to a 3rd degree burn
Prophylactic systemic antibiotics should be given routinely
Topical antibiotics should not be used due to selection for resistant organisms in the wound
Burn wound infection is the most common infection in a burn patient

Question 10 - Select the INCORRECT response regarding burns that require admission to hospital or a burn centre:

2nd and 3rd degree burns greater than 10% of BSA in patients under 10 and over 50 years of age
2nd and 3rd degree burns greater than 20% of BSA in patients of any age
2nd and 3rd degree burns posing a serious threat of cosmetic impairment
3rd degree burns greater than 10% BSA in any age
Inhalation injury

Question 11 - 50-year-old female has 3rd degree burns over her head, neck face and both arms. What percent of her body has been burned?

18%
27%
36%

Scarlet Red dressing
Allevyn
Silver sulfadiazine
Acetic acid dressing

Question 14 - Prognosis in burn patients is best determined by:

BSA burn percentage, age of patient, and presence of inhalation injury
BSA burn percentage, and length of exposure to injurious agent
BSA burn percentage and age of patient
Age of patient and presence of an inhalation injury
Age of patient and length of exposure to injurious agent
