Which of the following is a component of the lethal diamond?

• A. Coagulopathy
• B. Hyperkalemia
• C. Hypoglycemia
• D. Hypertension

Answer: (A)

The lethal diamond describes four deadly problems that commonly accompany severe hemorrhage and resuscitation: coagulopathy, hypothermia, acidosis, and hypocalcemia. Coagulopathy is central because when clotting ability is impaired, bleeding continues and the cycle worsens as temperature drops and acid builds up, further hampering clot formation. In transfusion scenarios, citrate can also lower calcium, feeding the coagulopathy. So, coagulopathy is the component that fits the lethal diamond. The other options—hyperkalemia, hypoglycemia, and hypertension—aren’t part of this defined set, even though they can occur in critical illness or during massive transfusion.
