A client asks the nurse to describe what causes a murmur. What would be the correct response by the nurse?
"Poor electric impulse conduction through the heart
"Turbulent blood flow through the heart valves"
"Enlargement of the left ventricle."
"Weak contraction of the atria."
"Long-term systemic hypertension."
The Correct Answer is B
A. Poor electrical impulse conduction may lead to arrhythmias but does not cause a murmur.
B. A heart murmur is caused by turbulent blood flow, often through narrowed or leaking valves, creating an abnormal heart sound.
C. Left ventricular enlargement can contribute to other cardiac issues but does not directly cause murmurs.
D. Weak atrial contractions may lead to decreased cardiac output but not necessarily to a murmur.
E. While hypertension can affect the heart, it is not the direct cause of a murmur.

Correct Answer is A
Explanation
A. A heave (or lift) often indicates ventricular hypertrophy or enlargement, suggesting increased workload on the heart.
B. Turbulent blood flow may lead to murmurs but is not specifically associated with a heave.
C. A persistently slow heartbeat is referred to as bradycardia and does not correlate with a heave.
D. An extreme pulse deficit relates to discrepancies between heartbeats and palpable pulses but is not linked to a heave.
E. Coronary artery blockage would not directly produce a heave; it typically leads to ischemic changes.
Correct Answer is B
Explanation
A. Venous insufficiency typically presents with swelling and pain that worsens with prolonged standing, not with exercise.
B. Claudication is the correct term, as it describes pain due to decreased blood flow to the muscles during exercise, often relieved by rest, which matches the patient's symptoms.
C. Muscle cramps may cause pain but are usually not consistently triggered by activity and relieved by rest.
D. Deep vein thrombosis would typically present with pain, swelling, warmth, and redness rather than exercise-induced pain relieved by rest.
E. Bruit from turbulent blood flow is an audible sound over an artery and not directly related to the type of pain described.
