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.

Answer and Explanation

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 D

Explanation

A. Clear and equal breath sounds bilaterally

Explanation: Clear and equal breath sounds bilaterally indicate normal lung sounds, suggesting proper air exchange in both lungs. This is a normal finding and does not require immediate reporting.

B. Oxygen saturation of 98% on room air

Explanation: An oxygen saturation level of 98% on room air indicates adequate oxygenation of the blood. This is a normal and healthy oxygen saturation level and does not require immediate reporting.

C. Cough producing clear, thin sputum

Explanation: A cough producing clear, thin sputum is indicative of a non-infected or non-inflammatory condition in the respiratory system. Clear and thin sputum is often normal, especially in the absence of other symptoms. It does not require immediate reporting unless the client has other concerning symptoms.

D. Visible use of accessory muscles during inhalation

Explanation: Visible use of accessory muscles, such as neck or intercostal muscles, during inhalation suggests that the client is working hard to breathe. This could indicate respiratory distress, potentially due to conditions like asthma, COPD (Chronic Obstructive Pulmonary Disease), or other severe lung problems. It's a concerning sign and should be reported to the healthcare practitioner promptly for further evaluation and intervention.

A. Indicates the beginning of diastole B. Coincides with the carotid artery pulse C. is louder than an S1 D. Is caused by the closure of the semilunar valves

Correct Answer is D

Explanation

A. Indicates the beginning of diastole: This statement is not accurate. S2, the second heart sound, indicates the end of systole and the beginning of diastole. It is specifically associated with the closure of the aortic and pulmonary valves.

B. Coincides with the carotid artery pulse: This statement is not accurate. S2 is associated with the closure of the aortic and pulmonary valves in the heart, not with the carotid artery pulse.

C. Is louder than an S1: This statement is not accurate. S1, the first heart sound, is usually louder than S2. S1 is associated with the closure of the mitral and tricuspid valves and marks the beginning of systole.

D. Is caused by the closure of the semilunar valves: This statement is accurate. S2 is caused by the closure of the aortic and pulmonary valves, which are the semilunar valves in the heart. It marks the end of systole and the beginning of diastole.
