Which formula is used in the Parkland method for initial burn resuscitation in the first 24 hours?
4 mL x weight (lb) x %TBSA burned
6 mL x weight (kg) x %TBSA burned
4 mL x weight (kg) x %TBSA burned - Explanation: Parkland formula specifies 4 mL/kg/%TBSA for the first 24 hours using crystalloid (typically LR).
2 mL x weight (kg) x %TBSA burned
undefined
The first half of the Parkland-calculated fluid volume is administered in the first 8 hours from the time of injury.
True
False
undefined
Which fluid is preferred for Parkland formula resuscitation?
3% Hypertonic Saline
0.45% Normal Saline
5% Dextrose in Water (D5W)
Lactated Ringer's - Explanation: LR is preferred due to its electrolyte composition and reduced risk of hyperchloremic acidosis compared with normal saline.
undefined
In calculating %TBSA for Parkland, which burn depth is included?
Only full-thickness burns
Superficial burns only
Partial-thickness and full-thickness burns - Explanation: Only second- and third-degree areas count toward TBSA; superficial (first-degree) burns are excluded.
All burned areas including erythema
undefined
A 70 kg adult has 30% TBSA partial-thickness burns. What is the total 24-hour Parkland volume?
2,100 mL
8,400 mL - Explanation: 4 mL x 70 x 30 = 8,400 mL in 24 hours.
12,600 mL
4,200 mL
undefined
A 60 kg adult with 25% TBSA burn presents 2 hours after injury. How much fluid remains to infuse in the first phase and over how long?
6,000 mL over the next 8 hours
3,000 mL over the next 8 hours
3,000 mL over the next 6 hours - Explanation: Total 24h = 4x60x25=6,000 mL; first half 3,000 mL in 8h from injury. Arriving at 2h leaves 6h to give the remaining first-half volume.
6,000 mL over the next 6 hours
undefined
Which rule is commonly used at the bedside to estimate adult %TBSA for Parkland calculations?
Rule of Nines - Explanation: The Rule of Nines quickly estimates adult TBSA; the Lund-Browder chart offers more precision, especially in children.
CHA2DS2-VASc
APGAR score
Glasgow Coma Scale
undefined
In a child, which TBSA estimation method is preferred for accuracy when available?
Adult Rule of Nines only
Lund-Browder chart - Explanation: Pediatric body proportions differ; Lund-Browder adjusts for age.
Parkland chart
Wallace burn index
undefined
For adult arms in the Rule of Nines, approximately what %TBSA does one entire arm represent?
9% - Explanation: Each entire arm (anterior+posterior) is 9% in adults.
1%
4.5%
18%
undefined
In adults, how much of the Parkland volume is given in the second phase?
The remaining half over the next 16 hours - Explanation: 50% in first 8h from injury, 50% in the subsequent 16h.
None; only the first 8 hours matter
All remaining volume over the next 8 hours
One third over 16 hours
undefined
Which statement about normal saline vs LR in burn resuscitation is most accurate?
NS is hypotonic and therefore avoided
LR is preferred to avoid hyperchloremic acidosis - Explanation: Large volumes of NS can cause hyperchloremic metabolic acidosis; LR mitigates this risk.
NS is preferred because it contains lactate for buffering
Either is fine; neither affects acid-base status
undefined
A 65 kg adult with 40% TBSA burns. Calculate the initial infusion rate for the first 8 hours at time 0 (no delay).
325 mL/hr
2,600 mL/hr
650 mL/hr - Explanation: 4x65x40=10,400 mL; half 5,200 mL in 8h = 650 mL/hr.
1,300 mL/hr - Explanation: Total 24h = 4x65x40=10,400 mL; first 8h half=5,200 mL; rate=5,200/8=650 mL/hr. Wait, that is 650 mL/hr. Correction: 5,200/8=650 mL/hr.
undefined
The Parkland formula is designed to cover both resuscitation and ongoing maintenance metabolic needs in adults.
False
True
undefined
For a child, the urine output target during resuscitation is typically higher than for adults.
False
True
undefined
Which component of TBSA is 1% in the adult Rule of Nines?
One arm
Perineum - Explanation: In adults, perineum constitutes about 1% TBSA.
Anterior trunk
Entire head
undefined
Which is the correct adult Rule of Nines distribution for one lower limb (entire leg)?
18% - Explanation: Each entire lower limb is 18% in adults.
9%
14%
4.5%
undefined
In pediatric patients, the head represents a larger %TBSA than in adults.
False
True
undefined
Parkland formula recommends colloid administration within the first 8 hours for all major burns.
False
True
undefined
A 80 kg adult with 35% TBSA burn has an initial urine output of 10 mL/hr. What is the best immediate action?
Switch to hypertonic saline immediately
Wait 6 hours without changes
Increase the fluid rate - Explanation: Target is ~0.5 mL/kg/hr (about 40 mL/hr for 80 kg). Low UO suggests under-resuscitation.
Stop fluids and give diuretics
undefined
When calculating Parkland in chemical burns without large TBSA involvement, aggressive fluid resuscitation is often unnecessary.
False
True
undefined

Study Outcomes

  1. Calculate Fluid Requirements -

    Apply the Parkland formula to determine the appropriate fluid volume for burn resuscitation based on patient weight and percentage of total body surface area burned.

  2. Assess Burn Size -

    Evaluate the percentage of total body surface area (TBSA) affected by burns to ensure precise fluid management decisions.

  3. Apply Practice Questions -

    Engage with parkland formula practice questions to sharpen problem-solving skills in diverse burn management scenarios.

  4. Interpret Quiz Feedback -

    Analyze results from the parkland formula quiz to identify knowledge gaps and reinforce critical care concepts.

  5. Prepare for Certification -

    Use targeted CEN burn formula practice to build confidence and readiness for burn resuscitation components of critical care exams.

Cheat Sheet

  1. Accurate TBSA Assessment -

    Master the Rule of Nines for adults and Lund & Browder charts for children to estimate total body surface area (TBSA) burned precisely. For example, each adult leg is 18%, each arm is 9%, and the head is 9%. This accuracy is critical in parkland formula practice questions to avoid under” or over”resuscitation (American Burn Association).

  2. Core Parkland Formula Calculation -

    Use the formula 4 mL × body weight (kg) × %TBSA to calculate the 24-hour crystalloid requirement, administering half in the first 8 hours and the rest over 16 hours. For instance, a 70 kg patient with 30% burns needs 4×70×30=8400 mL of lactated Ringer's. Quizzing yourself with these parkland formula practice questions helps build speed and confidence.

  3. Timing and Infusion Scheduling -

    Always start the clock at the time of injury, not hospital arrival, when solving parkland formula quiz scenarios; if a patient presents 2 hours post”burn, the first half of fluids must be given in the next 6 hours. This nuance often appears in burn resuscitation formula questions to test real”world readiness (UpToDate, J Trauma Acute Care Surg).

  4. Optimal Fluid Choice -

    Lactated Ringer's is the fluid of choice due to its balanced electrolyte profile and reduced risk of hyperchloremic acidosis compared to normal saline. Remember the mnemonic "LS in Burn Care" (Lactated S=Solution) for your CEN burn formula practice. Crystalloid remains first-line during initial 24 hours per international guidelines.

  5. Endpoints and Adjustment Strategies -

    Monitor urine output (0.5 mL/kg/hr in adults, 1 mL/kg/hr in pediatrics) as your primary endpoint; vital signs, lactate, and base deficit are secondary parameters. Adjust the infusion rate by 10 - 20% based on these values to fine-tune resuscitation and avoid complications like volume overload.
