Which patient is in decompensated shock?

Which patient is in decompensated shock?

• A. A 20-year-old female with absent radial pulses and dilated pupils
• B. A 25-year-old male with rapid, strong pulse
• C. A 40-year-old female with warm skin and good capillary refill
• D. A 60-year-old male with normal blood pressure

Answer: (A)

Decompensated shock happens when the body's compensatory mechanisms can no longer maintain adequate blood flow to vital organs. Signs include weak or absent central pulses, altered mental status, cool or mottled skin, and often a drop in blood pressure. The patient with no radial pulse and dilated pupils illustrates this stage: the circulation to the extremities is lost and brain perfusion is impaired, signaling that perfusion is failing and urgent intervention is needed. The other presentations fit stages or states that are not decompensated: a rapid, strong pulse suggests the body is still compensating; warm skin with good capillary refill indicates maintained perfusion; and normal blood pressure means the patient hasn’t yet progressed to decompensation.
