A nurse is reinforcing teaching with an older adult client who has been newly diagnosed with a heart murmur. Which of the following statements should the nurse make?
"A heart murmur is a high-pitched sound due to a narrow valve."
"A heart murmur is an extra sound your heart makes due to blood entering an inflexible chamber."
"This means that there is some inflammation around your heart."
"This indicates turbulent (chaotic, random fluctuations) blood flow through a valve."
The Correct Answer is D
A. "A heart murmur is a high-pitched sound due to a narrow valve." While some murmurs may be caused by a narrow valve (stenosis), not all murmurs are high-pitched. Murmurs vary in pitch depending on the cause, so this is not a comprehensive explanation.
B. "A heart murmur is an extra sound your heart makes due to blood entering an inflexible chamber." This describes an S3 or S4 sound rather than a murmur. A heart murmur is typically related to turbulent blood flow through valves, not just an inflexible heart chamber.
C. "This means that there is some inflammation around your heart." This statement incorrectly links a murmur to pericarditis or myocarditis, which involve inflammation. A murmur is associated with abnormal blood flow, not inflammation.
D. "This indicates turbulent (chaotic, random fluctuations) blood flow through a valve." A heart murmur is caused by turbulent blood flow, which can occur when blood moves through a valve that is narrow or has regurgitation. This is the correct explanation.

Explanation
A. Monitor your blood pressure on a regular basis: Regular monitoring of blood pressure is important for clients taking lisinopril to ensure the medication is effectively controlling hypertension.
B. Your cholesterol levels must be monitored monthly while taking this medication: Lisinopril does not typically require monthly cholesterol monitoring. This instruction is more relevant for statins or other lipid-lowering agents.
C. Report the development of a persistent dry cough.: A dry cough is a common side effect of ACE inhibitors like lisinopril. Clients should report this side effect as it may necessitate discontinuing the medication.
D. Your diet should include plenty of potassium-rich foods daily: Lisinopril can increase potassium levels, potentially causing hyperkalemia. Clients should be advised to avoid excessive potassium intake, not to increase it.
