Which of the following is one of the Ts in the Hs and Ts approach?

• A. Tension Pneumothorax
• B. Tamponade
• C. Toxins
• D. Thrombosis Coronary

Answer: (D)

In ACLS, you think about reversible causes of cardiac arrest organized as Hs and Ts. The Ts include Thrombosis (coronary or pulmonary), Toxins, Tamponade, and Tension pneumothorax. Coronary thrombosis is a clot in a heart artery that can trigger a myocardial infarction and precipitate arrest, so it clearly fits as one of the Ts. Recognizing this helps you target urgent reperfusion actions once resuscitation is underway. The other options—toxins, tamponade, and tension pneumothorax—are also Ts, so they share the same category, but coronary thrombosis specifically embodies the Thrombosis component.
