The nurse assesses the adult patient who weighs 132lb and discovers the following areas to be affected by burns: anterior trunk, anterior and posterior right leg, and anterior and posterior right arm. Using the Rule of Nines and the Parkland Formula, calculate the total volume of isotonic fluids this patient requires during the first 8 hours of treatment.

A) Heart rate of 130 beats per minute
A heart rate of 130 beats per minute is tachycardia, which is often a compensatory response to injury, particularly in cases of trauma, blood loss, or shock. It is common in the initial phase after trauma as the body attempts to compensate for decreased blood volume or oxygen delivery. However, tachycardia alone is not typically fatal in the immediate post-injury period and can often be managed.

B) pH of 7.21 (normal 7.35–7.45)
A pH of 7.21 indicates acidosis, which is life-threatening and typically arises from shock, blood loss, or severe trauma. Acidosis occurs when the body is unable to compensate for lactic acid or other metabolic byproducts that accumulate due to insufficient oxygen delivery to tissues. In the case of a gunshot wound to the abdomen, there is a high risk of internal bleeding, hypoperfusion, and hypoxia, all of which can lead to metabolic acidosis. Severe acidosis can cause organ failure, particularly affecting the heart, kidneys, and brain.

C) Serum potassium 5.7 mEq/L (normal 3.5–5.3)
A serum potassium of 5.7 mEq/L is elevated, but it is moderately high and not typically life-threatening unless it reaches much higher levels (e.g., >6.0 mEq/L), which can cause cardiac arrhythmias. Elevated potassium can occur due to cellular injury (e.g., muscle trauma or rhabdomyolysis), but it would need to be corrected to prevent complications like arrhythmias.

D) Platelet count 200,000 (normal 150,000–450,000)
A platelet count of 200,000 is within the normal range (150,000–450,000) and does not indicate a problem with coagulation. The blood loss and the NG tube hemorrhage mentioned in the scenario suggest that the patient may be at risk for bleeding, but a platelet count in the normal range suggests that the body’s ability to form clots is likely intact.

A) Blood pressure 102/78:
This blood pressure is within an acceptable range, especially after resuscitation with fluids and blood products. While hypotension is a concern in hypovolemic shock, this blood pressure is stable and does not indicate an immediate need for intervention. Blood pressure monitoring is essential, but this finding is not as urgent as other options.

B) Pulse oximetry 95%:
A pulse oximetry reading of 95% is generally considered within normal limits for a patient who has undergone resuscitation and is stable. Oxygen saturation levels should be monitored, but this finding does not indicate an immediate need for intervention. Values below 90% would be more concerning, especially in trauma patients, but 95% is acceptable.

C) Crackles at bilateral bases:
The presence of crackles at the bilateral lung bases is a sign of pulmonary edema, which can occur as a result of fluid overload, especially after aggressive resuscitation with fluids like lactated Ringer's solution (LR) and blood products. In hypovolemic shock, rapid infusion of fluids can overwhelm the heart's ability to handle the volume, leading to fluid accumulation in the lungs. This finding is concerning because it can indicate a shift from hypovolemic shock to a state of volume overload, which can worsen respiratory function and lead to acute respiratory distress syndrome (ARDS).

D) Heart rate 105 beats per minute:
A heart rate of 105 beats per minute is slightly elevated but can be expected in a patient who has experienced trauma and is undergoing fluid resuscitation. Tachycardia is often seen in hypovolemic shock as the body compensates for decreased circulating volume. While monitoring the heart rate is important, this finding does not indicate an immediate life-threatening concern compared to crackles in the lungs, which suggest pulmonary edema.
