A nurse is explaining to a client with asthma what her new prescription for prednisone, a systemic corticosterioid, is used for in the treatment of asthma. What would be the most accurate explanation that the nurse could give?
To ensure long-term prevention of asthma exacerbations
To gain control of inadequately controlled, persistent asthma
To cure any systemic infection underlying asthma attacks
To prevent recurrent pulmonary infections
The Correct Answer is B
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.

Correct Answer is ["125"]
Explanation
To calculate the amount of mL that the client should receive, we need to use the formula:
mL = (g * 5 mL) / mg
where g is the ordered dose of the medication, mg is the concentration of the medication, and mL is the volume of the solution.
Plugging in the given values, we get:
mL = (4 g * 5 mL) / 160 mg
Simplifying, we get:
mL = 0.125 g/mL
Multiplying by 1000 to convert grams to milligrams, we get:
mL = 125 mg/mL
Therefore, the client should receive 125 mL of the solution.
Correct Answer is B
Explanation
A. Intermittent claudication:
Intermittent claudication is more commonly associated with peripheral arterial insufficiency rather than venous insufficiency. It is caused by inadequate blood flow to the muscles during activity, resulting in cramping or pain that typically resolves with rest.
B. Brownish discoloration to the legs:
Brownish discoloration to the legs, often referred to as hemosiderin staining, is a common finding in peripheral venous insufficiency. It occurs due to the breakdown of red blood cells and the deposition of hemosiderin in the tissues, especially around the ankles.
C. Weak or absent pedal pulses:
Weak or absent pedal pulses are more indicative of peripheral arterial insufficiency rather than venous insufficiency. Peripheral arterial disease can result in decreased blood flow to the extremities, leading to diminished pulses.
D. Unequal peripheral pulses between extremities:
Unequal peripheral pulses between extremities are also more suggestive of arterial insufficiency. Conditions such as atherosclerosis or arterial embolism can cause variations in pulses between different limbs.
