A nurse is assessing a client who has COPD. The nurse should expect the client's chest to be which of the following shapes?

A. Montelukast: Montelukast is a leukotriene receptor antagonist commonly used in the management of asthma and allergic rhinitis. It is not part of the standard tuberculosis treatment regimen.

B. Rifampin: Rifampin is a key component of tuberculosis treatment and is effective against both active and latent tuberculosis.

C. Acyclovir is an antiviral medication primarily used for herpes simplex virus infections and is not part of the standard treatment for tuberculosis.

D. Isoniazid: Isoniazid is another essential drug in the treatment of tuberculosis, particularly for the prevention of latent tuberculosis progression to active disease.

E. Pyrazinamide: Pyrazinamide is part of the standard combination therapy for tuberculosis.

A. Foot ulcers: Foot ulcers are more commonly associated with the later stages of peripheral arterial disease (PAD) when there is significant impairment of blood flow to the extremities, leading to tissue damage and delayed wound healing.

B. Intermittent claudication: This is the correct answer. Intermittent claudication is a classic symptom of PAD in the early stage. It is characterized by cramping leg pain or discomfort that occurs during physical activity, such as walking, and is relieved by rest. It is caused by insufficient blood flow to meet the demands of the muscles during exercise.

C. Rest pain: Rest pain is typically a symptom of more advanced PAD. It occurs when blood flow is severely compromised even at rest, leading to pain in the affected extremity that is not relieved by activity.

D. Dependent rubor: Dependent rubor is a sign of severe PAD and occurs when the foot or leg becomes red or flushed when in a dependent position. It is associated with compromised arterial blood flow.
