ACLS Basics 4

Question 1

Which of the following is a 'T' in the ACLS H's and T's mnemonic for reversible causes of cardiac arrest?

Accepted Answer

Thrombosis (pulmonary or coronary)

Answer

Thrombosis (pulmonary embolism or coronary occlusion) is one of the reversible T's to consider during cardiac arrest.

Question 2

During CPR, what is the recommended allowable chest recoil technique?

Accepted Answer

Allowing full chest recoil after each compression

Answer

Full chest recoil after each compression allows the heart to refill with blood, improving cardiac output during CPR.

Question 3

What is the correct dose of epinephrine for a patient in pulseless ventricular fibrillation?

Accepted Answer

1 mg IV/IO every 3–5 minutes

Answer

Epinephrine 1 mg IV/IO is administered every 3–5 minutes during cardiac arrest regardless of rhythm.

Question 4

Which of the following describes high-quality CPR in an adult?

Accepted Answer

Compression depth of at least 2 inches at 100–120 compressions/min

Answer

High-quality adult CPR requires compressions at least 2 inches deep at a rate of 100–120 per minute with full chest recoil.

Question 5

Which condition is classified as an 'H' in the ACLS reversible causes mnemonic?

Accepted Answer

Hypothermia

Answer

Hypothermia is one of the H's — severe hypothermia can mimic cardiac arrest and requires warming as a reversible treatment.
