Most of the deaths from burn trauma in the emergent phase that require a referral to a burn center result from:
cardiac arrest related to septic shock
Infection
adrenal failure
hypovolemic shock and renal failure.
The Correct Answer is D
A. Cardiac arrest related to septic shock:
Septic shock can occur in burn patients due to the breakdown of the skin barrier, which allows pathogens to enter the bloodstream and cause systemic infection. However, while septic shock is a serious complication of burn injuries, it is not the primary cause of death in the emergent phase. Septic shock can lead to multiple organ failure and contribute to mortality, but it is often a later complication rather than an immediate cause in the emergent phase.
B. Infection:
Infections are a significant concern in burn patients, especially as the burn wound provides an ideal environment for bacterial growth. However, infections typically contribute more significantly to mortality in the later phases of burn care rather than in the emergent phase. In the emergent phase, hypovolemic shock and other immediate complications have a greater impact on mortality.
C. Adrenal failure:
Adrenal failure, specifically acute adrenal insufficiency or Addisonian crisis, can occur in burn patients due to the stress response and corticosteroid depletion. While adrenal insufficiency is a concern in severe burn cases, it is not the primary cause of death in the emergent phase requiring referral to a burn center.
D. Hypovolemic shock and renal failure:
Hypovolemic shock is a critical concern in the emergent phase of burn trauma because burns can lead to significant fluid loss and electrolyte imbalances. Hypovolemic shock results from insufficient circulating blood volume, leading to inadequate perfusion of organs and tissues, which can be life-threatening. Additionally, renal failure can develop due to hypovolemia, decreased cardiac output, and the release of inflammatory mediators, leading to acute kidney injury (AKI). Hypovolemic shock and subsequent renal failure are major contributors to mortality in the emergent phase of burn trauma, necessitating prompt referral to a burn center for specialized care.

Correct Answer is D
Explanation
A. Diabetic ketoacidosis (DKA) in a person with emphysema:
In DKA, there is typically metabolic acidosis due to the accumulation of ketones in the blood, leading to a decrease in pH. However, the respiratory compensation mechanism in DKA usually results in a decreased PaCO2 (respiratory alkalosis) rather than an elevated PaCO2 as seen in the blood gas values provided. Additionally, emphysema is associated with chronic respiratory acidosis, not respiratory alkalosis as indicated by the elevated PaCO2.
B. Diarrhea for 36 hours in an older, frail woman:
Prolonged diarrhea can lead to metabolic acidosis due to the loss of bicarbonate through the gastrointestinal tract. The pH of 7.12 and the decreased HCO3- (22 mEq/L) suggest metabolic acidosis. However, the elevated PaCO2 (respiratory acidosis) is not consistent with pure metabolic acidosis caused by diarrhea. Respiratory acidosis typically occurs due to hypoventilation or respiratory dysfunction.
C. Anxiety-induced hyperventilation in an adolescent:
Anxiety-induced hyperventilation can lead to respiratory alkalosis due to excessive blowing off of CO2, resulting in a decrease in PaCO2. The pH of 7.12 is consistent with acidosis, but the elevated PaCO2 contradicts respiratory alkalosis. Anxiety-induced hyperventilation would typically result in a higher pH and lower PaCO2.
D. Bronchial obstruction related to aspiration of a hot dog:
A bronchial obstruction causing inadequate ventilation can lead to respiratory acidosis due to CO2 retention. The pH of 7.12 and the elevated PaCO2 (65 mm Hg) indicate respiratory acidosis. This situation is consistent with the blood gas values provided.
Correct Answer is A
Explanation
A. Colonization - replicating microorganisms: not yet Infected
This pairing is correct. Colonization refers to the presence and replication of microorganisms on the wound surface. At this stage, the wound is not yet infected, as there may be microorganisms present, but they have not caused an inflammatory response or tissue damage.
B. Systemic infection - Wound is darker than the surrounding skin with noted drainage present
This description does not match the stage of systemic infection. Systemic infection refers to an infection that has spread beyond the initial wound site, affecting the entire body systemically. The symptoms of systemic infection may include fever, increased heart rate, malaise, and altered mental status. The description provided seems more indicative of a local infection with drainage.
C. Contaminated - infection beyond the wound
This pairing is incorrect. Contaminated wounds refer to wounds with a high risk of infection due to the presence of foreign material or significant contamination. However, contamination does not necessarily mean that an infection has already developed beyond the wound. It signifies a risk of infection but does not define the infection stage itself.
D. Local infection - sepsis
This pairing is incorrect. A local infection is confined to the wound site and may present with symptoms such as erythema, warmth, swelling, pain, and purulent drainage. Sepsis, on the other hand, is a severe systemic response to infection, characterized by widespread inflammation and organ dysfunction. Sepsis is not synonymous with a local infection; it represents a more advanced and life-threatening stage of infection.
