A client was recently diagnosed with a heart murmur and is asking the nurse for more information. The nurse will educate the client that a heart murmur:
indicates turbulent blood flow through a valve.
is an extra sound due to blood entering an inflexible chamber.
means that there is some inflammation around the heart.
is a high-pitched sound due to a narrow valve.
The Correct Answer is A
A. Indicates turbulent blood flow through a valve:
This statement is correct. A heart murmur is an abnormal sound during the heartbeat cycle, often indicating turbulent blood flow through a valve. Murmurs can result from various factors such as valve disorders, structural abnormalities, or other heart conditions.
B. Is an extra sound due to blood entering an inflexible chamber:
This statement is not accurate. Heart murmurs are primarily associated with turbulent blood flow rather than an extra sound related to an inflexible chamber.
C. Means that there is some inflammation around the heart:
This statement is incorrect. Heart murmurs are not specifically related to inflammation around the heart. They are primarily caused by issues with blood flow through the heart valves.
D. Is a high-pitched sound due to a narrow valve:
This statement is a bit oversimplified. While murmurs can sometimes be associated with narrow valves (stenosis), they can also result from various other valve abnormalities or conditions, and not all murmurs are high-pitched. The pitch and characteristics of a murmur can provide clues about its cause, but they are not the sole indicators.

Correct Answer is ["B","C","D","E"]
Explanation
A. Age: While age itself is not modifiable, it is included in the list because aging increases the risk of developing cardiovascular disease. However, individuals cannot change their age, so it is not a modifiable risk factor.
B. Smoking: Smoking is a significant risk factor for cardiovascular disease. It damages the heart and blood vessels and can lead to atherosclerosis (narrowing and hardening of the arteries), which can result in heart attacks and strokes.
C. Hypertension: High blood pressure is a leading cause of cardiovascular disease. It can damage the arteries over time, making them more susceptible to atherosclerosis.
D. Diabetes: Diabetes, especially if poorly controlled, increases the risk of cardiovascular disease. High blood sugar levels can damage the blood vessels and the heart.
E. High cholesterol: Elevated levels of cholesterol, especially low-density lipoprotein (LDL) cholesterol, can lead to the buildup of plaque in the arteries, increasing the risk of atherosclerosis and cardiovascular events.
Correct Answer is B
Explanation
A. AV node - SA node - bundle of His - bundle branches:
This sequence is incorrect. The SA node (sinoatrial node) initiates the electrical impulse in the heart, followed by the AV node (atrioventricular node), bundle of His, and then the bundle branches.
B. SA node - AV node - bundle of His - bundle branches:
This sequence is correct. The electrical stimulus of the cardiac cycle starts at the SA node, which is the natural pacemaker of the heart. From the SA node, the impulse travels to the AV node, then to the bundle of His, and finally to the bundle branches, which distribute the impulse to the ventricles, causing them to contract.
C. Bundle of His - AV node - SA node - Erb's Point:
This sequence is incorrect. Erb's Point is a point on the chest where heart sounds S2 and S3 can be heard most distinctly.
D. AV node - SA node - bundle of His - Erb's Point:
This sequence is incorrect. The AV node comes after the SA node in the electrical conduction system of the heart. Erb's Point is not a part of the normal cardiac conduction pathway; it is a location for auscultation on the chest.
