A patient with new third-degree burns over 60% of the body is confused and presents with a blood pressure of 79/56 mm Hg, heart rate of 132 beats/min, and respirations of 28 breaths/min with crackles on auscultation.
The patient’s body temperature is 76° F, and the skin is pale and clammy. Which stage of shock is this patient experiencing?

Irreversible.

End-organ dysfunction.

Early reversible.

Preshock.

Answer and Explanation

The Correct Answer is C

Choice A rationale:

Irreversible shock is the final stage of shock, where the body's compensatory mechanisms have failed, and damage to vital organs is irreversible. This stage is characterized by:

Profound hypotension (systolic blood pressure persistently below 60 mmHg) Severely altered mental status (unresponsiveness or coma)

Widespread organ failure (kidney failure, liver failure, respiratory failure) Lack of response to aggressive fluid resuscitation and vasopressor therapy

The patient in the question does not exhibit all of these signs and symptoms, particularly the profound hypotension and irreversible organ failure. Therefore, irreversible shock is not the most likely stage.

Choice B rationale:

End-organ dysfunction is a stage of shock where inadequate tissue perfusion has begun to cause damage to vital organs. This stage is characterized by:

Hypotension that may respond to fluid resuscitation

Signs of organ dysfunction, such as decreased urine output, altered mental status, or respiratory distress

The patient in the question does have some signs of organ dysfunction, such as confusion and crackles on lung auscultation. However, the hypotension is not as severe as typically seen in end-organ dysfunction shock, and there is no mention of other organ dysfunction like decreased urine output. Therefore, end-organ dysfunction is not the most likely stage.

Choice C rationale:

Early reversible shock is the initial stage of shock, where the body's compensatory mechanisms are still able to maintain blood pressure and organ perfusion. This stage is characterized by:

Mild to moderate hypotension Tachycardia

Cool, clammy skin Narrowed pulse pressure Restlessness or anxiety

The patient in the question presents with all of these signs and symptoms, making early reversible shock the most likely stage.

Choice D rationale:

Preshock is a state of impending shock, where the body's compensatory mechanisms are activated but not yet fully effective. This stage is characterized by:

Normal or slightly low blood pressure Tachycardia

Cool, clammy skin Restlessness or anxiety

The patient in the question has hypotension, which is not consistent with preshock. Therefore, preshock is not the correct stage.

Correct Answer is A

Explanation

Choice A rationale:

Hypovolemic shock is a life-threatening condition that occurs when the body loses a significant amount of blood or fluids, leading to a decrease in circulating blood volume. This can result in inadequate perfusion of organs and tissues, which can cause damage and even death if not treated promptly.

In this case, the athlete's symptoms and vital signs are consistent with hypovolemic shock. The athlete has been practicing twice a day in the heat, which can lead to significant fluid loss through sweating. The athlete is also dizzy, which is a common symptom of hypovolemia due to decreased blood flow to the brain. The athlete's blood pressure is low (100/2 mm Hg), pulse rate is elevated (100 beats/minute), and respiratory rate is increased (26 breaths/minute), all of which are compensatory mechanisms to try to maintain blood pressure and perfusion in the setting of hypovolemia. The athlete's skin is cool to touch

and pale in color, which is due to decreased blood flow to the skin. The athlete also does not remember the last voiding time, which may indicate decreased urine output, another sign of hypovolemia.

Key points supporting hypovolemic shock:

Significant fluid loss due to exercise in the heat Dizziness

Low blood pressure Elevated pulse rate Increased respiratory rate Cool, pale skin

Decreased urine output Additional details:

Hypovolemic shock can be caused by various factors, including:

Hemorrhage (blood loss) Severe dehydration Burns

Severe vomiting or diarrhea

Treatment for hypovolemic shock typically involves:

Intravenous fluid replacement to restore circulating blood volume Blood transfusion if the shock is due to hemorrhage

Oxygen therapy to support breathing

Medications to support blood pressure and heart function

A. Metabolic alkalosis. B. Metabolic acidosis. C. Respiratory alkalosis. D. Respiratory acidosis.

Correct Answer is B

Explanation

Choice A rationale:

Metabolic alkalosis is characterized by a high pH (above 7.45), high bicarbonate (HCO3-) levels, and normal or low PaCO2. The patient's ABGs show a low pH (7.26), low bicarbonate (14 mEq/L), and low PaCO2 (30 mm Hg), which are not consistent with metabolic alkalosis.

Choice C rationale:

Respiratory alkalosis is characterized by a high pH (above 7.45), low PaCO2, and normal or slightly elevated bicarbonate levels. The patient's ABGs do show a low PaCO2, but the pH is low (acidic) and the bicarbonate is low, which are not consistent with respiratory alkalosis.

Choice D rationale:

Respiratory acidosis is characterized by a low pH (below 7.35), high PaCO2, and normal or slightly elevated bicarbonate levels. The patient's ABGs do show a low pH, but the PaCO2 is also low, which is not consistent with respiratory acidosis.

Rationale for the correct answer, B:

Metabolic acidosis is characterized by a low pH (below 7.35), low bicarbonate levels, and normal or low PaCO2. The patient's ABGs are consistent with metabolic acidosis because they show a low pH (7.26), low bicarbonate (14 mEq/L), and low PaCO2 (30 mm Hg).

Acute kidney injury is a common cause of metabolic acidosis. The kidneys play a vital role in regulating acid-base balance by excreting acids and reabsorbing bicarbonate. When the kidneys are damaged, they are unable to excrete acids effectively, leading to an accumulation of acids in the blood and a decrease in bicarbonate levels.

Additional Information:

It's important to note that the patient's low PaCO2 is likely a compensatory mechanism for the metabolic acidosis. In response to acidosis, the respiratory system tries to increase ventilation to blow off more carbon dioxide, which helps to raise the pH. However, this compensatory mechanism is often not enough to fully correct the acidosis.
