A client in the rehabilitative phase of a burn injury has healed graft sites and is beginning mobility exercises.
Which intervention is most important to minimize scarring and promote functional recovery?

Disseminated intravascular coagulation involves systemic activation of coagulation, leading to microthrombi formation. Assessing for organ dysfunction requires understanding how thrombotic microangiopathy causes ischemia in high-vascularity organs, specifically focusing on renal and hepatic biomarkers and physiological changes in perfusion.

Choice A rationale

Thrombotic microangiopathy in the lungs would typically cause increased respiratory rates and decreased oxygen saturation due to impaired gas exchange. Decreased rates and normal saturation do not indicate the ischemic damage associated with microvascular clotting.

Choice B rationale

The kidneys are highly susceptible to microthrombi. Elevated BUN (normal 10 to 20 mg/dL) and creatinine (normal 0.6 to 1.2 mg/dL) indicate acute kidney injury caused by fibrin deposition and subsequent ischemia in the glomerular capillaries.

Choice C rationale

While bilirubin might rise due to hemolysis, white blood cell counts are not a primary indicator of thrombotic organ dysfunction. Bilirubin increases are more common in hepatic failure or red blood cell fragmentation during DIC.

Choice D rationale

DIC typically presents with abnormal coagulation profiles, including prolonged PT and PTT and low fibrinogen. Normal profiles would contradict the diagnosis of DIC, even if transaminases were elevated due to localized hepatic microvascular occlusion.

Splenic rupture involves internal hemorrhage and peritoneal irritation. Assessing this requires understanding Kehr sign and signs of hypovolemic shock. Knowledge of hemodynamic parameters and abdominal symptoms is essential to identify occult bleeding and impending cardiovascular collapse following trauma.

Choice A rationale

Splenic injury causes blood to accumulate in the peritoneal cavity, leading to abdominal pain and distension. This irritation of the peritoneum is a hallmark sign of internal organ damage following blunt force trauma to the left side.

Choice B rationale

Headaches are not typically associated with splenic injury unless there is concurrent head trauma. While shock can cause lightheadedness, a primary headache is not a specific or supportive clinical indicator for an isolated splenic laceration or rupture.

Choice C rationale

Hypotension occurs as a result of significant internal bleeding and decreased circulating blood volume. Blood pressure falls below the normal systolic range of 90 to 120 mmHg as the body fails to compensate for acute blood loss.

Choice D rationale

Tachycardia is a compensatory mechanism where the heart rate increases above 100 beats per minute to maintain cardiac output during hemorrhage. It is often one of the earliest signs of volume depletion and internal splenic bleeding.

Choice E rationale

Polyuria, or excessive urination, is not a sign of splenic injury or hypovolemia. In fact, blood loss usually leads to oliguria, where urine output drops below 30 mL per hour as the kidneys conserve fluid and sodium.

Choice F rationale

Wide pulse pressure is often seen in conditions like aortic regurgitation or increased intracranial pressure. Splenic rupture causes hypovolemia, which typically results in a narrow pulse pressure as the systolic pressure falls and diastolic pressure stays.

Choice G rationale

Nausea is a common symptom of peritoneal irritation and the systemic response to acute internal bleeding. The presence of blood in the abdominal cavity can stimulate the vagus nerve and gastrointestinal distress, leading to vomiting or nausea.
