ACLS Pretest
Section 1: Basic Life Support (BLS) & Initial Assessment
1.What is the first step when encountering an unresponsive patient?oA) Check for a pulse oB) Activate emergency response oC) Begin chest compressions oD) Check for breathing
Answer: B) Activate emergency response
Explanation: Early activation ensures prompt advanced care.
2.How long should you check for a pulse in an unresponsive patient?oA) 5 seconds oB) 10 seconds oC) 15 seconds oD) 20 seconds
Answer: B) 10 seconds
Explanation: Prolonged assessment delays life-saving interventions.
3.What is the correct compression rate during CPR?oA) 60–80 compressions/min oB) 80–100 compressions/min oC) 100–120 compressions/min oD) 120–140 compressions/min
Answer: C) 100–120 compressions/min
Explanation: This rate maximizes circulation without causing fatigue.
4.What is the recommended compression depth for an adult?oA) 1–1.5 inches oB) 1.5–2 inches oC) At least 2 inches 1 / 2
oD) More than 3 inches
Answer: C) At least 2 inches
Explanation: Ensures effective perfusion without excessive injury.
5.Which is the correct ventilation rate for a patient with an advanced airway?oA) 1 breath every 4 seconds oB) 1 breath every 6 seconds oC) 1 breath every 8 seconds oD) 1 breath every 10 seconds
Answer: B) 1 breath every 6 seconds
Explanation: Prevents hyperventilation, which reduces cardiac output.
Section 2: Cardiac Arrest & Rhythms
6.Which rhythms are shockable in cardiac arrest?oA) Pulseless electrical activity (PEA) and asystole oB) Ventricular fibrillation (VF) and pulseless ventricular tachycardia (pVT) oC) Bradycardia and SVT oD) First-degree AV block and atrial fibrillation
Answer: B) VF and pVT
Explanation: Defibrillation is effective for these rhythms.
7.What is the initial shock energy for biphasic defibrillation?oA) 50 J oB) 100 J oC) 120–200 J oD) 360 J
Answer: C) 120–200 J
Explanation: Follow the device manufacturer’s recommendation.
8.What is the first medication administered in a shockable rhythm cardiac arrest?oA) Amiodarone
