The nurse is caring for a patient who has decreased mobility. Which intervention is a simple and cost-effective method for reducing the risks of stasis of pulmonary secretions and decreased chest wall expansion?

A. Frequent change of position:

Frequent changes in position help prevent pooling of secretions and promote lung expansion. This simple and cost-effective measure is important in preventing complications related to immobility, such as pneumonia and atelectasis. It aids in maintaining optimal respiratory function.

B. Antibiotics: Antibiotics are used to treat bacterial infections and would not directly address the risks associated with decreased mobility.

C. Oxygen humidification: While oxygen therapy may be necessary in some cases, humidification is typically used to prevent drying of mucous membranes and is not a primary intervention for preventing complications of decreased mobility.

D. Chest physiotherapy: Chest physiotherapy involves techniques to mobilize respiratory secretions and may be indicated in specific situations. However, it is not as simple and cost-effective as frequent changes in position.

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.
