Which client does the nurse assess most carefully for obstructive shock?

Choice A reason: Full thickness burns involve the destruction of all skin layers and underlying structures, leading to a massive inflammatory response and "capillary leak" syndrome. This loss of intravascular fluid into the interstitial space causes a profound decrease in circulating volume, known as burn-induced hypovolemic shock.

Choice B reason: Hypertension is not an expected finding in the acute phase of a major burn injury. The primary hemodynamic challenge is hypotension due to fluid loss and systemic vasodilation. Hypertension would only be seen much later in the recovery phase or as a result of a pre-existing condition.

Choice C reason: Fluid volume deficit is a certainty in large percentage burns. The loss of the skin barrier leads to massive evaporative water loss, while the systemic inflammatory response causes fluid to shift from the vascular compartment into the tissues, resulting in severe dehydration and intravascular depletion.

Choice D reason: An increased pulse rate, or tachycardia, is a compensatory mechanism by the sympathetic nervous system. In response to a decreased stroke volume from fluid loss, the heart beats faster to attempt to maintain adequate cardiac output and perfusion to vital organs during the shock state.

Choice E reason: Decreased cardiac output occurs during the initial "eb b" phase of burn shock. The combination of reduced intravascular volume (low preload) and the release of myocardial depressant factors during the systemic inflammatory response leads to a significant reduction in the heart's overall pumping efficiency.

Choice A reason: This client is exhibiting signs of emotional distress and potential depression related to their injury. While psychological support is a critical component of burn rehabilitation, it is not a life-threatening emergency and does not take priority over hemodynamic instability or acute physiological decline.

Choice B reason: This client is demonstrating signs of hypovolemic shock or early sepsis, evidenced by hypotension (MAP < 65 mm Hg). In burn patients, fluid shifts and loss of skin barrier make them highly susceptible to circulatory collapse. Immediate assessment and fluid resuscitation are required to prevent organ failure.

Choice C reason: Postoperative pain is expected and requires intervention; however, pain is not more stable than a compromised blood pressure. While the nurse should address the pain promptly, the client with hemodynamic instability represents a higher risk for immediate mortality and must be assessed first.

Choice D reason: A potassium level of 5.0 mEq/L is at the high end of normal, and a hematocrit of 55% is common in the first 24 hours of burn care due to hemoconcentration. These findings are expected in the emergent phase and do not require more immediate action than hypotension.
