#1
Which of the following is a common symptom of a myocardial infarction (heart attack)?

ExplanationPrompt actions to improve outcomes.
#4
Which of the following is a characteristic symptom of a pulmonary embolism?
Gradual onset of shortness of breath
ExplanationSlow development of breathing difficulty.
#5
Which of the following is a primary symptom of an aortic dissection?
Sharp, tearing chest pain
ExplanationSevere, distinct pain due to a tear in the aorta.
#6
What is the first-line treatment for ventricular fibrillation?
Defibrillation
ExplanationImmediate delivery of an electrical shock to restore normal heart rhythm.
#7
Which of the following is NOT a risk factor for cardiovascular disease?
Regular exercise
ExplanationRegular exercise is a protective factor, not a risk factor for heart disease.
#8
What is the purpose of administering oxygen during a cardiovascular emergency?
To improve oxygenation of tissues
ExplanationEnhances oxygen delivery to vital organs.
#9
What is the most common initial rhythm in sudden cardiac arrest?
Ventricular fibrillation
ExplanationAbnormal heart rhythm leading to ineffective pumping.
#10
What is the primary goal of prehospital management in cardiovascular emergencies?
Stabilize the patient's condition
ExplanationCritical for preventing further deterioration.
#11
Which of the following is NOT a sign of acute coronary syndrome?
Persistent cough
ExplanationTypically presents with chest pain, not cough.
#12
What is the role of an automated external defibrillator (AED) in prehospital management?
Deliver electrical shocks to correct abnormal heart rhythms
ExplanationCritical for restoring normal heart rhythm.
#13
Which of the following is a common sign of congestive heart failure?
Peripheral edema
ExplanationFluid buildup leading to swelling in extremities.
#14
What is the recommended initial treatment for stable angina?
Beta-blockers
ExplanationHelps reduce the workload on the heart.
#15
Which of the following medications is commonly used to reduce preload in heart failure?
Furosemide
ExplanationDiuretic that decreases fluid buildup.
#16
What is the most common cause of sudden cardiac arrest in young athletes?
Hypertrophic cardiomyopathy
ExplanationA condition where the heart muscle becomes abnormally thick, leading to arrhythmias.
#17
What is the recommended depth for chest compressions during CPR in adults?
3-4 inches
ExplanationAdequate depth ensures effective circulation.
#18
What is the recommended ratio of compressions to ventilations during CPR in adults?
30:2
ExplanationOptimal cycle for chest compressions and ventilation.
#19
Which of the following is a potential complication of defibrillation?
Cardiac tamponade
ExplanationRare but serious; excess fluid around the heart.
#20
What is the recommended initial dose of epinephrine in the treatment of cardiac arrest?
1 mg
ExplanationAdministered to stimulate heart activity.
#21
Which of the following is a potential complication of administering nitroglycerin?
Headache
ExplanationCommon side effect due to vasodilation.
#22
What is the recommended action if a patient becomes unresponsive during a cardiovascular emergency?
Perform chest compressions
ExplanationInitiates circulation and maintains blood flow.
#23
Which of the following is a common side effect of administering aspirin in the prehospital setting?
Gastrointestinal bleeding
ExplanationMay cause stomach irritation and bleeding.
#24
What is the purpose of administering atropine in bradycardia?
To increase heart rate
ExplanationStimulates the heart's electrical conduction.
#25
Which of the following is a potential complication of administering morphine in acute coronary syndrome?
Hypotension
ExplanationMay cause a sudden drop in blood pressure.
