Which of the following is NOT among the five T's?

• A. Tension Pneumothorax
• B. Tamponade (Cardiac)
• C. Trauma
• D. Thrombosis (Pulmonary)

Answer: (C)

The idea being tested is the ACLS framework of reversible causes of cardiac arrest, often taught as the five Hs and five Ts. The five T’s encompass tension pneumothorax, cardiac tamponade, toxins, thrombosis (pulmonary), and thrombosis (myocardial). Trauma isn’t listed as one of these five T’s, even though chest or blunt trauma can lead to problems like tamponade or tension pneumothorax or cause hemorrhage leading to hypovolemia. In others words, trauma can precipitate the T-type conditions, but it isn’t itself one of the five Ts used in this mnemonic. That’s why trauma is the correct choice for NOT being among the five Ts.
