The nurse should place a client being admitted to the hospital with suspected tuberculosis (TB) on what type of isolation?

A. Coronary artery disease (CAD):

Coronary artery disease primarily affects the blood vessels supplying the heart muscle. Symptoms often include chest pain (angina) rather than pain in the lower extremities. The symptoms described in the scenario are not characteristic of CAD.

B. Arterial embolus:

An arterial embolus is a blood clot or debris that travels through the bloodstream and can block an artery. While it can cause decreased blood flow and pain, the presentation in the lower left leg and foot with relief of pain at rest is more suggestive of peripheral arterial disease (PAD) or intermittent claudication rather than an acute arterial embolus.

C. Raynaud disease:

Raynaud's disease is characterized by episodes of reduced blood flow to the extremities, usually triggered by cold or stress. It typically involves color changes (white, blue, red) in the fingers or toes. The symptoms described, including pain in the lower leg and foot during walking, are not typical of Raynaud's disease.

D. Intermittent claudication:

Intermittent claudication is a symptom associated with peripheral arterial disease (PAD). It involves pain or cramping in the legs during physical activity, such as walking, due to reduced blood flow to the muscles. Rest typically relieves the pain. The observation of a hairless leg and slight edema suggests potential vascular compromise in the lower extremity, supporting the diagnosis of intermittent claudication.

A. International normalized ratio (INR):

INR is a test used to monitor the effectiveness of anticoagulant therapy, particularly drugs like warfarin. It measures the time it takes for blood to clot. It's not directly related to assessing heart failure but is more associated with monitoring anticoagulation status.

B. Brain natriuretic peptide (BNP):

BNP is a peptide released by the heart in response to increased pressure and volume in the heart, often seen in heart failure. Elevated BNP levels can indicate the presence of heart failure. It's a useful diagnostic marker for heart failure.

C. Troponin:

Troponin is a protein released into the blood when there is damage to the heart muscle, usually during a heart attack. It is not specific to heart failure but is commonly used to diagnose myocardial infarction (heart attack).

D. Creatinine:

Creatinine is a waste product that comes from the normal wear and tear on muscles. While elevated creatinine levels can be seen in conditions affecting kidney function, it's not a direct marker for assessing heart failure. However, kidney function is often evaluated in conjunction with heart failure assessments.
