"Long-term systemic hypertension."

Answer and Explanation

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.

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 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.

A. Pulse 60 B. Pulse 90 C. Oxygen saturation of 92% D. Oxygen saturation 89% E. Blood pressure 130/80

Correct Answer is D

Explanation

A. A pulse of 60 is low but does not necessarily indicate a need to stop suctioning if the patient remains stable otherwise.
B. A pulse of 90 is within normal limits and does not require stopping suctioning.
C. An oxygen saturation of 92% is slightly low but still acceptable; suctioning can continue if the client is stable.
D. An oxygen saturation of 89% is below the acceptable threshold and indicates hypoxia, prompting the nurse to stop suctioning immediately to avoid further compromising the client's respiratory status.
E. A blood pressure of 130/80 is within normal limits and does not warrant cessation of suctioning.
