CARDIOVASCULAR SYSTEM (HARD)


CARDIOVASCULAR SYSTEM (HARD)Version en ligne CARDIOVASCULAR SYSTEM MCQ par SITI RABIATUL ADAWIYAH ABDUL RAHIM 1 The following conditions are most often indicated by a prolonged PR interval: (HARD) a Atrial fibrillation b First-degree AV block c Bundle branch block d Hypertrophy of the ventricles 2 Why does an ECG's QRS complex have a substantially bigger amplitude than its P wave? a Compared to the ventricles, the atria contract more forcefully b The ventricles produce greater electrical activity and have bigger muscle mass c Both atrial and ventricular depolarization are present in the P wave d The atria repolarize as part of the QRS complex, strengthening it. 3 How much blood is in each ventricle at the conclusion of atrial systole, and what is the name of this volume? (HARD) a 70 mL, stroke volume b 50 mL, end-systolic volume c 130 mL; end-diastolic volume d 100 mL; ejection fraction 4 What is a common effect of increased blood pressure on the cardiovascular system? a Decreased heart rate b Increased oxygen supply to muscles c Increased workload on the heart d Reduced blood flow to the brain 5 What is the role of the Purkinje fibers in the heart? a To provide structural support to the heart b To conduct electrical impulses throughout the ventricles c To prevent backflow of blood in the heart d To temporarily hold blood before it is pumped from the heart 6 Which of the following is the primary cause of the dicrotic notch in the aortic pressure waveform? a Closure of AV valves b Opening of semilunar valves c Closure of aortic valve d Ventricular systole 7 What condition is associated with abnormal and uncoordinated contraction of heart muscle, often life-threatening? a Bradycardia b Fibrillation c Tachycardia d AV block 8 Which cardiac structure delays the electrical impulse, allowing atrial contraction before the ventricles contract? a SA node b AV node c Bundle of His d Purkinje fibers 9 What effect does sympathetic nervous system stimulation have on heart rate? a Decreases heart rate b No effect c Increases heart rate d Halts the heartbeat 10 What happens to the heart valves when the ventricles contract? a The heart stops beating b The atrioventricular valves open, and the semilunar valves close c The semilunar valves open, and the atrioventricular valves close d All valves remain open simultaneously. Feedback 1 ANSWER B: An atrioventricular (AV) node conduction delay is indicated by a prolonged PR interval (more than 0.20 seconds). This is referred to as a first-degree AV block, and although it is typically asymptomatic, an ECG can show it. 2 ANSWER B : The ventricles produce higher electrical activity because they have bigger muscle mass. The reason for this is that because the ventricles are bigger and stronger than the atria, their electrical depolarization causes a greater voltage change, which raises the amplitude of the QRS complex. Because it reflects the atria's lower depolarization, the P wave is smaller. 3 ANSWER C: The end-diastolic volume (EDV), which is equivalent to the volume of blood in each ventricle at the conclusion of atrial systole, is 130 milliliters. Prior to contraction, it symbolizes the ventricle's maximum blood volume. 4 ANSWER : C Elevated blood pressure forces the heart to pump harder, leading to increased myocardial oxygen demand and potential hypertrophy over time. The heart's increased workload may lead to heart failure, where the heart struggles to maintain adequate blood circulation throughout the body. 5 ANSWER : B Purkinje fibers are specialized cardiac muscle fibers that facilitate rapid conduction of electrical impulses, ensuring synchronized ventricular contraction. They originate from the bundle of His and spread throughout the ventricular myocardium, allowing for efficient pumping of blood. 6 ANSWER: C The dicrotic notch represents a brief rise in aortic pressure following the closure of the aortic valve, due to elastic recoil. 7 ANSWER : B Fibrillation is a chaotic contraction pattern, especially dangerous when it occurs in the ventricles (ventricular fibrillation). 8 ANSWER : B The AV node slows down the signal from the SA node, giving the atria time to contract before the ventricles are stimulated. 9 ANSWER : C Sympathetic stimulation increases heart rate and contractility to meet the body’s increased demand for blood and oxygen. 10 ANSWER : C During ventricular contraction, known as systole, pressure increases within the ventricles, leading to the opening of the semilunar valves.The closure of the atrioventricular valves prevents backflow of blood into the atria, ensuring efficient blood flow into the arteries.
