Study Guide Newest Actual Questions
and Answers (A+ Guide Solution)
1. What is the primary function of the coronary arteries?
A. Supply blood to the brain
B. Supply blood to the heart muscle
C. Return deoxygenated blood to the lungs
D. Circulate blood to the extremities
B. Supply blood to the heart muscle
Rationale: The coronary arteries branch from the aorta and supply oxygenated blood
to the myocardium, ensuring the heart muscle receives nutrients and oxygen to function
effectively.
2. A 60-year-old male presents with chest pain radiating to his left arm. What is the
most likely cause?
A. Pulmonary embolism
B. Acute myocardial infarction
C. Pneumothorax
D. Esophageal rupture
B. Acute myocardial infarction
Rationale: Chest pain radiating to the left arm is a classic symptom of acute
myocardial infarction (AMI), caused by reduced blood flow to the heart muscle due to
coronary artery occlusion.
3. What is the appropriate compression depth for adult CPR?
A. 1.0–1.5 inches
B. 2.0–2.4 inches
C. 3.0–3.5 inches
D. 4.0–4.5 inches
B. 2.0–2.4 inches
Rationale: According to the American Heart Association, adult CPR requires chest
compressions to a depth of 2.0–2.4 inches to ensure adequate circulation.
4. Which rhythm is shockable by an AED in cardiac arrest?
A. Asystole
B. Pulseless electrical activity
C. Ventricular fibrillation
D. Sinus bradycardia
C. Ventricular fibrillation
Rationale: Ventricular fibrillation (V-Fib) is a shockable rhythm because it involves
chaotic electrical activity that can be corrected with defibrillation. Asystole and PEA are
non-shockable.

5. What is the compression-to-ventilation ratio for two-rescuer adult CPR?
A. 15:2
B. 30:2
C. 5:1
D. 10:1
B. 30:2
Rationale: The American Heart Association recommends a 30:2 compression-to-
ventilation ratio for two-rescuer adult CPR to balance circulation and oxygenation.
6. A patient with chest pain has a BP of 180/100. What condition should you suspect?
A. Cardiogenic shock
B. Hypertensive emergency
C. Pulmonary edema
D. Stable angina
B. Hypertensive emergency
Rationale: A blood pressure of 180/100 with chest pain suggests a hypertensive
emergency, which requires immediate medical intervention to prevent organ damage.
7. What is the primary action of nitroglycerin in treating chest pain?
A. Increases heart rate
B. Dilates coronary arteries
C. Constricts peripheral veins
D. Reduces blood pressure only
B. Dilates coronary arteries
Rationale: Nitroglycerin is a vasodilator that primarily dilates coronary arteries,
increasing blood flow to the myocardium and relieving ischemic chest pain.
8. When should you check for a pulse in an unresponsive infant?
A. Carotid artery
B. Femoral artery
C. Brachial artery
D. Radial artery
C. Brachial artery
Rationale: The brachial artery is the preferred site for pulse checks in infants due to
its accessibility and reliability in small patients.
9. What does the P wave represent on an ECG?
A. Ventricular depolarization
B. Atrial depolarization
C. Ventricular repolarization
D. Atrial repolarization
B. Atrial depolarization
Rationale: The P wave on an ECG represents atrial depolarization, the electrical
activity that triggers atrial contraction.
10. A patient in cardiac arrest receives a “no shock advised” message from the AED.
What should you do next?
A. Administer epinephrine
B. Resume chest compressions
C. Check for breathing
