1. A patient in the emergent phase of a major burn injury has a blood pressure of 88/50
mmHg and a heart rate of 124 bpm. Which physiological process primarily explains these
findings?
A. Increased systemic vascular resistance due to catecholamine release
B. Loss of sympathetic tone leading to peripheral vasodilation
C. Reduced cardiac output resulting from myocardial infarction
D. Massive fluid shift from the intravascular to the interstitial space
Answer: D
Rationale: In the emergent phase of burns, increased capillary permeability leads to ‘burn
shock,’ where plasma and electrolytes leak into the interstitium, causing hypovolemia.
2. A client weighing 75 kg has sustained full-thickness burns to 40% of their total body surface
area (TBSA). Using the Parkland formula, how much Lactated Ringer’s should be administered
in the first 8 hours?
A. 6,000 mL
B. 12,000 mL
C. 3,000 mL
, D. 4,500 mL
Answer: A
Rationale: Parkland Formula: 4 mL x kg x % TBSA. Total = 4 x 75 x 40 = 12,000 mL. Half is
given in the first 8 hours: 12, = 6,000 mL.
3. Which assessment finding is the most sensitive indicator of adequate fluid resuscitation in
a patient being treated for hypovolemic shock?
A. Systolic blood pressure greater than 100 mmHg
B. Heart rate between 60 and 100 bpm
C. Urine output of at least 0.5 mL/kg/hr
D. Capillary refill time less than 2 seconds
Answer: C
Rationale: Urine output is the most reliable non-invasive indicator of organ perfusion and
fluid volume status during shock resuscitation.
4. An arterial blood gas (ABG) report shows: pH 7.28, PaCO2 55 mmHg, and HCO3 26 mEq/L.
Which condition does the nurse suspect?
A. Uncompensated respiratory acidosis
B. Fully compensated metabolic acidosis
C. Partially compensated respiratory alkalosis
D. Uncompensated metabolic alkalosis
