The physician orders warfarin (Coumadin) 10 mg PO to be administered to a client at 1800 today. The pharmacy only has 2.5 mg tablets available. How many tablets will the nurse administer?

A. Diaphragmatic breathing:

Diaphragmatic breathing, also known as abdominal or deep breathing, is a normal and effective way of breathing. It involves the contraction and relaxation of the diaphragm, allowing for efficient lung expansion. This is a healthy and efficient breathing technique.

B. Controlled breathing:

Controlled breathing refers to a deliberate and regulated breathing pattern. It can include techniques such as paced breathing, where the individual consciously controls the rate and depth of their breaths. Controlled breathing is generally considered a positive and intentional approach to managing respiratory function.

C. Pursed-lip breathing:

Pursed-lip breathing is a breathing technique where the individual breathes in through the nose and exhales through pursed lips. This method is often taught to individuals with certain respiratory conditions, such as chronic obstructive pulmonary disease (COPD), to help improve lung function and alleviate shortness of breath. Pursed-lip breathing can be a helpful strategy in specific situations.

D. Use of accessory muscles:

The use of accessory muscles indicates that the person is experiencing increased difficulty in breathing. Accessory muscles, such as the neck and shoulder muscles, are not typically heavily involved in breathing under normal circumstances. When these muscles are visibly working during breathing, it suggests increased respiratory effort and can be a sign of respiratory distress or difficulty.

A. To ensure long-term prevention of asthma exacerbations:

This statement is not accurate. Prednisone is typically not used for long-term prevention of asthma exacerbations. It is more commonly prescribed for short-term use during acute exacerbations to quickly reduce inflammation and improve symptoms.

B. To gain control of inadequately controlled, persistent asthma:

This is the most accurate explanation. Prednisone is often prescribed to gain control over inadequately controlled, persistent asthma by providing anti-inflammatory effects and helping to manage symptoms during acute episodes.

C. To cure any systemic infection underlying asthma attacks:

Prednisone is not used to cure infections. While it can have anti-inflammatory and immunosuppressive effects, its primary role in asthma is to reduce airway inflammation and control symptoms, not to treat underlying infections.

D. To prevent recurrent pulmonary infections:

Prednisone is not typically prescribed for the prevention of infections. Its use in asthma is more focused on managing inflammation and symptoms during acute exacerbations rather than preventing infections.
