The nurse is caring for a client, with no other pertinent medical history, who was burned over 709% Total Body Surface Area (TBSA) and weighs 70kg. Using the Parkland Formula, calculate the amount of intravenous fluid required in the first 8 hours after the burn.
2.600mL
9,800 ml
4,900mL
19,600mL
The Correct Answer is B
Parkland Formula:
Total fluid requirement (ml)=4×Body weight (kg)×Total body surface area burned (%TBSA)
= 4×70×70
=19,600mL (total for 24 hours)
Fluids in first 8 hours: 19,600mL÷2
=9,800mL

Correct Answer is D
Explanation
A. Gently cleanse the wounds with warm soapy water
Initial burn care focuses on preventing hypothermia and infection. Cleaning is usually performed in a controlled setting like a burn unit, not in the emergency phase.
B. Remove blistered skin and cover with a dry dressing
Blisters should not be removed in the initial phase unless they are large and tense. Removal increases the risk of infection.
C. Apply saline-soaked wet-to-dry dressings
Wet dressings can lead to hypothermia in burn patients, which worsens outcomes. Dry coverings are preferred.
D. Cover with a clean dry sheet to prevent hypothermia
Burn patients lose heat rapidly due to loss of skin integrity. Covering with a clean, dry sheet helps prevent hypothermia and infection before transfer.
Correct Answer is C
Explanation
A. Urine output of less than 0.5 mL/kg
Norepinephrine is a vasopressor used to improve perfusion. A urine output of less than 0.5 mL/kg suggests ongoing hypoperfusion and inadequate organ perfusion, which is an undesirable outcome.
B. Improved mental status, decreased lactate level
These are positive indicators of improved perfusion and oxygen delivery, but they are not the primary target for norepinephrine therapy.
C. A mean arterial pressure (MAP) of 65
A MAP of at least 65 mmHg is the target for vasopressor therapy, as it ensures adequate perfusion of vital organs.
D. A pain level of 4 or less on a scale of 0-10
While pain management is important, norepinephrine’s primary role is not pain control but rather maintaining adequate perfusion.
