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 B
Explanation
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.
Correct Answer is B
Explanation
A. Standard precautions:
Standard precautions are the basic level of infection control and should be used for all patient care. These precautions include practices like hand hygiene, the use of personal protective equipment (PPE), and safe injection practices.
B. Airborne precautions:
These precautions are used to prevent the transmission of infectious agents that are spread through the air. In the case of tuberculosis (TB), which is caused by Mycobacterium tuberculosis, airborne precautions are necessary to reduce the risk of airborne transmission.
C. Contact precautions:
Contact precautions are used for patients with known or suspected infections that can be transmitted by direct or indirect contact. Examples include Clostridium difficile infection and multidrug-resistant organisms. These precautions involve the use of PPE and may include patient placement in a private room.
D. Droplet precautions:
Droplet precautions are used when a patient is known or suspected to be infected with pathogens that are transmitted by respiratory droplets. Examples include influenza and certain types of bacterial meningitis. These precautions include placing the patient in a private room and using PPE.
